BabA-Leb binding intensity by radioimmunoassay with 125I-labelled

BabA-Leb binding intensity by radioimmunoassay with 125I-labelled conjugate showed a variation among individual H. pylori strains (18, 19). Marked heterogeneity in babA genetic content and BabA expression among H. pylori strains has been reported (19, 26). Regarding the relationship between the status of babA2 and BabA adhesion, 44% of babA2-negative strains were bound to Leb in Sweden, while 45% of babA2-positive strains showed no binding capacity to Leb in Portugal (23), possibly due to uncertain PCR detection with a single primer. We determined the status of babA2 by PCR with two primer pairs. babA2-positive or -negative

strains were each defined as being positive or negative by all primer

pairs. Where a contradiction was found, the PCR amplicons Selleck BMN 673 were subjected to sequence analysis to confirm the babA2 sequence. Evaluation for both BabA MBS and the subtle difference in the BabA amino acid sequence (middle region (AD1–5)) might allow determination of the extent of the BabA functional adhesion (18). Thus, the alignment of BabA sequences was analyzed in HPK5 and 20 randomly chosen isolates. The sequence analyses showed that the diversity of the BabA middle region was not a determinant of the degree of BabA-MBS, which is consistent with a previous report (24). Interestingly, find more the prevalence of AD2 (90.5%) was considerable greater than that reported previously (45.5%) (24), indicating that variation of the BabA middle region might exist within Japan. SabA is a prerequisite for the non-opsonic activation of human neutrophils (27), evokes a strong inflammatory response in human neutrophils (28) and has been identified as the sialic acid-dependent hemagglutinin based on sialidase-sensitive hemagglutination (29), suggesting that SabA is a candidate virulence molecule. However, the evidence explaining the association of SabA and its pathogenesis is not enough. SabA expression is regulated by CT-dinucleotide

repeats and the number of CT repeats depends on environmental conditions (5, AMP deaminase 17). Although the interaction between host sialyl-Lewis x and H. pylori SabA determines the degree of bacterial colonization in patients lacking gastric Leb, the sequence of the sabA gene, irrespective of CT repeats, is not a reliable predictor of SabA expression (30). Thus, the status of both babA2 and sabA genes does not always reflect these functions, implying that it is critical to evaluate the functional binding efficacy of BabA and SabA. The Leb-nonbinding strain with weak expression of BabA, but not the Leb-binding strain with strong expression of BabA, is associated with more severe mucosal injury and worse clinical outcome, suggesting that in vitro binding activity does not accurately reflect in vivo effects (19).

These studies underscore, quantitatively, the dominance and impor

These studies underscore, quantitatively, the dominance and importance of signal-activated transcription factors downstream of T-cell receptor (TCR) signalling and cytokine receptor signalling in initiation of T-cell polarization. Further, they reflect how co-operative binding of transcription BGB324 chemical structure factors to combinatorial motifs across the genome is a common strategy for the activation of lineage-specific enhancers. Treatment of fibroblasts with the DNA methyltransferase inhibitor 5-azacytodine results in de-repression of a number of genes and their conversion to myoblasts. Davis, Weintraub and Lassar discovered myogenic differentiation 1 (MYOD) to be highly induced under these conditions

and went on to show its sufficiency for myogenesis in a number of cell types.[8] Since this discovery, a number of ‘master regulator’ transcription factors have been described, with the notable characteristic that their expression in immediate precursor cells (and sometimes alternative lineages, in so-called ‘transdifferentiation’) PF-562271 clinical trial is necessary and ‘sufficient’ for differentiation and acquisition of distinctive cell-type-specific characteristics. Genomic approaches allow for the study of the global activity of such transcription factors. For example, MYOD functions in the global de novo activation of enhancers involved in muscle growth and differentiation;

MYOD is required for acquisition of chromatin characteristics associated with active enhancers: monomethylation of histone 3, lysine 4 (H3K4me1),

recruitment of PolII and the histone acetyltransferase, p300, and histone acetylation (characteristically of H3K27).[9] The ability of ‘master regulator’ transcription factors to “open” and activate latent lineage-specific regulatory DNA is intuitive and appealing in its simplicity – it represents a single-step mechanism for the extraction of information from dispersed regulatory DNA and its use in the control of cell-type-specific transcription. Dichloromethane dehalogenase Enhancer activation typically progresses from transcription factor binding at specific DNA motifs to recruitment of ‘co-activators’ – histone and chromatin modifying factors such as the SWItch/Sucrose Non-Fermentable chromatin remodelling complex and histone-modifying enzymes, like p300 – and the recruitment of general transcription factors and PolII, often with physical interaction with the associated gene promoter.[10, 11] Several studies suggest that complex and incremental control of regulatory elements and their chromatin states by sequentially and co-operatively acting transcription factors underlies the progressive alteration of enhancer states through differentiation.[3, 12-15] However, some factors—definitive ‘pioneer factors’—have the capacity to bind to nucleosomal DNA or higher-order chromatin and establish enhancer accessibility and responsiveness to subsequent binding of other factors.

These results suggest that MS activates human PDL cells to expres

These results suggest that MS activates human PDL cells to express immune/defence genes encoding cytokines, chemokines, defensins and TLRs via a SIRT1 pathway. Orthodontic tooth movement is achieved by the remodelling of alveolar bone and periodontal ligaments (PDL) in response to mechanical loading [1]. The host response to orthodontic force has been described as an aseptic and transitory inflammation, Selleck SAHA HDAC mediated by a variety of endogenous mediators such as cytokines and chemokines, which are involved in adaptive and innate immunity [2]. Chemokines are a superfamily of small chemotactic cytokines recognized

as regulators of inflammatory reactions, and Omipalisib molecular weight the development of an appropriate immune response by co-ordinating leucocyte recruitment [3]. Mechanical stress (MS) or loading increases the production of chemokines and chemokine receptors, including interleukin (IL)-8 receptor in osteoblasts [4], IL-8 in human periodontal ligament (PDL) cells [5] and IL-11 and IL-8 in

human PDL cells [6]. A study has reported recently that chemokines such as monocyte chemoattractant protein (MCP)-1, regulated upon activation normal T cell expressed and secreted (RANTES) and macrophage inflammatory protein (MIP)-2 are up-regulated during rat orthodontic tooth movement [5]. However, an equibiaxial tensile strain of a low magnitude inhibits IL-1β-induced synthesis of IL-1β, IL-6 and IL-8 in PDL cells [7]. Furthermore, Lee et al. [8] reported that compressive stress

in PDL cells had no significant effect on IL-8 expression. In vivo, IL-1, IL-6, IL-8, IL-11 and tumour necrosis factor (TNF)-α are produced by inflammatory cells and periodontal tissue cells upon the application of orthodontic force [9]. The mechanisms involved in host immune responses to MS, however, are not completely understood. One host defence mechanism that involves activation of an innate immune response following exposure to the external environment is the production of defensins, small cationic anti-microbial Bumetanide peptides that are classified into the α- and β-defensin subfamilies [10]. Human β-defensin 1 (hBD-1) is expressed constitutively in epithelial cells, whereas hBD-2 and hBD-3 are expressed inducibly by bacteria, Candida albicans and inflammatory cytokines such as TNF-α and IL-1β[11]. Toll-like receptors (TLRs) are a transmembrane receptor family that plays a pivotal role in the modulation of immune response by recognizing pathogen-associated molecular patterns [12]. This recognition subsequently stimulates a sequence of signalling mechanisms, resulting ultimately in the production of various cytokines that serve as a link between innate and specific immune mechanisms.

The latter proteins not only link transmembrane TJ/AJ proteins an

The latter proteins not only link transmembrane TJ/AJ proteins and the actin cytoskeleton but also take part in intracellular signaling (Gonzalez-Mariscal et al., 2003). TJs are composed of the integral transmembranous proteins, occludin, claudins, and junctional adhesion molecules (JAMs), while vascular endothelium cadherin (Ve-cadherin) is the major transmembrane protein of endothelial AJs. Transmembrane proteins of TJs are

connected to the actin cytoskeleton by TJ-anchoring proteins, zonula occludens proteins ZO-1, ZO-2, and ZO-3 (Fig. 1). Infections are quite common, but why do we BAY 80-6946 clinical trial only see infections of the CNS in rare occasions? One major factor is the special barrier BBB and its building blocks BMECs. BMECs and normal ECs differ from each other in functional and structural terms. Some of these differences are with respect to cytokine and growth-related molecules, stress-related proteins, metabolic enzymes, and signal transduction proteins (Lu et al., 2007). Several TJ proteins, see more including occludin, claudin-1, claudin-3, claudin-5, claudin-12, JAM-A, JAM-B, JAM-C, endothelial cell-selective adhesion molecule, ZO-1, ZO-2, cingulin, 7H6 antigen, and PAR-3, are expressed differentially in BMECs and peripheral vascular ECs (Nagasawa et al., 2006). For example, claudin-1, claudin-4, claudin-5, claudin-7, and

claudin-8 are less abundant in BMECs than in gut ECs; VCAM, ICAM-1, and E-selectin are induced in lower extent than in HUVEC; and the expression of endothelial nitric oxide synthase and ICAM-1 (approximately 30-fold) is lesser than in pulmonary ECs (Panes et al., Carnitine palmitoyltransferase II 1995; Stevens et al., 2001). Occludin and Ve-cadherin are expressed

much higher in BMECs compared to non-neuronal ECs (Hirase et al., 1997; Stevens et al., 2001). Similarly, researchers observed high abundance of Lutheran membrane glycoprotein (Shusta et al., 2002), CD46 complement regulator, and autoantigen Ro52 (Shusta et al., 2002)as well as relatively low expression of P-selectin and tissue factor pathway inhibitor on BMECs (Bajaj et al., 1999; Solovey et al., 2004). It is interesting to note that BMECs express unique cell surface glycoproteins that are not found on other ECs, such as the cerebral cell adhesion molecule, LK48, BBB-specific anion transporter 1, angiogenic factors (vascular endothelial growth factor, follistatin, fibroblast growth factor 1 and 5), and CXC chemokines with Glu-Leu–Arg motifs (epithelial cell-derived neutrophil-activating peptide 78 and growth-regulated oncogene-α) (Grab et al., 2005). BMECs interact dynamically with neighboring cells, astroglia, pericytes, and microglia that contribute to their unique characteristics. Despite the fact that astrocytes envelop more than 99% of the BBB endothelium, they are not directly involved in the physical properties of BBB (Hawkins & Davis, 2005).

In the most literal sense, granulomatosis indicates a condition c

In the most literal sense, granulomatosis indicates a condition characterized by multiple granulomas. Sarcoidosis is an archetype granulomatosis, although the term granulomatosis is rarely used in discussing or writing about sarcoidosis. In fact, the term granulomatosis is most often used selleck compound in the medical literature in the context of GPA (WG). Especially in the acute lesions of GPA

(WG), the predominant pattern of inflammation is not granulomatous, but purulent. Thus, the inflammation has the appearance of an abscess more than a granuloma (Fig. 2). Often, the only feature in the acute inflammatory lesions that is reminiscent of granulomatous inflammation is the presence of scattered multi-nucleated giant cells. As lesions age, they often develop APO866 nmr a central zone of necrosis that seems to evolve from extensive karyorrhectic (leucocytoclastic) debris to a central zone with a slightly basophilic hue, and finally to a central zone of amorphous acidophilic material (Fig. 3). Concurrent with this degeneration of the central zone of neutrophils, the periphery of the lesion accrues palisades of elongated macrophages and scattered multi-nucleated giant cells that justify being called granulomatous inflammation. Mark et al. [6] concluded that in GPA (WG):

‘Micronecrosis, usually with neutrophils (microabscesses), constitutes the early phase in the development of the pathognomonic organized palisading granuloma.’ They suggested that the multi-nucleated giant cells might be a secondary reactive response to the acute necrotizing lesions. This is supported PLEK2 by the finding of engulfed apoptotic and necrotic neutrophil debris that can be seen occasionally within the multi-nucleated giant cells at sites of necrotizing inflammation in GPA (WG) (Fig. 2b). This prominence of neutrophilic

infiltrates (microabscesses) in the acute phase of the disease and the atypicality of the granulomatous inflammation that follows have been reported in detail in the literature [6,7] but probably, in part because of the term ‘granulomatosis’ in the name, concepts and theories about the pathogenesis of the extravascular inflammation in GPA (WG) have drawn analogies to typical granulomatous inflammation as seen in sarcoidosis or tuberculosis, which has little or no resemblance to the granulomatosis of GPA (WG). In a careful pathological study of pulmonary specimens from 35 patients with GPA (WG), Mark et al. [6] concluded that: ‘Compact granulomas of tuberculoid or sarcoidal type did not occur in the cases of Wegener’s granulomatosis.

FISH confirmed the presence of Aspergillus and Candida within the

FISH confirmed the presence of Aspergillus and Candida within the infectious process, a prerequisite for inferring a causal relationship with the infection. The combination of broad-range PCR with sequence analysis and FISH applied on tissue samples is a powerful approach Selleck Navitoclax to identify the aetiology of invasive fungal infections, including mixed infections. “
“Fluconazole, which is a drug of the azole family, is safely used in systemic treatment of oral and intravenous injection, but it is difficult to use fluconazole as a topical application because

of its large molecular weight and strong hydrophilic property. This study is a multicentre, double-blind, randomised, non-inferiority study to compare the antifungal effect and safety of fluconazole cream 0.5% and 1% with flutrimazole cream 1% in superficial mycosis. A total of 162 subjects selected to participate in this study were equally divided into three groups and assigned to be given fluconazole cream 0.5%, fluconazole

cream 1%, and flutrimazole cream 1% in the ratio of 1 : 1. The primary index of drug efficacy was determined by complete mycological cure in which no fungus was detected on KOH smear test 4 weeks after application of fluconazole. The secondary index of efficacy was defined as complete mycological cure 4 weeks after the application of fluconazole, improvement of clinical symptoms and overall effectiveness assessed by the research staff. According to this study, on comparing the efficacy of cure of superficial selleck chemicals dermatomycosis after 4 weeks of application, both fluconazole

0.5% and fluconazole 1% cream were found to be equally effective and non-inferior to flutrimazole 1% cream. Given the effectiveness and safety of the drug, both fluconazole 0.5% and 1% cream might be said to be optimal concentration in the treatment of superficial dermatomycosis. “
“Candida species are the fourth most common cause of nosocomial invasive infections. Biofilm formation is recognised as one virulence factor of Candida species. A total of 243 Candida albicans, 81 C. glabrata, 33 C. parapsilosis, 14 C. dubliniensis, 8 C. tropicalis, 8 C. lusitaniae, 5 C. Epothilone B (EPO906, Patupilone) krusei and 1 C. pelliculosa isolates causing bloodstream infections were evaluated for biofilm formation. The biofilm formed on silicone elastomer preincubated with human serum was quantified by estimation of the metabolic activity through XTT assay and visualised by light and scanning electron microscopy. Forty per cent of the C. albicans isolates formed biofilm compared to 88.7% of the non-albicans Candida isolates (P < 0.0001). Among non-albicans Candida spp., biofilm formation was most commonly observed in C. tropicalis and C. lusitaniae (100%), followed by C. glabrata (95%), C. dubliniensis (85.7%) and C. parapsilosis (66.7%). A quantitative correlation was observed between the amount of biofilm observed microscopically, and that determined by metabolic activity measurements.

We describe a recently encountered case of tumor lysis syndrome detected during detailed examination of lung cancer with liver metastasis. Methods & Results: The patient was a 79-year-old male. He was being managed at the Department of Nephrology of our hospital because of chronic kidney disease (Cr: 2.5 mg/dl). Early in April of XXXX, he developed pain involving the right hypochondrial region and anorexia. Because of intense malaise, he visited the outpatient critical care unit of our hospital on April 6. At that time, blood tests revealed marked elevation of

hepatobiliary enzymes, and CT scan disclosed a tumorous lesion approximately 13 cm in size in the right lobe of the liver. He was thus hospitalized to undergo detailed examination. Liver biopsy was performed on the 11th hospital day. Around April 15, his urine volume began to decrease, and blood tests the following day revealed elevation of BUN (60.0 mg/dl) and Cre (3.67 mg/dl), accompanied Maraviroc by uric acid elevation (22.2 mg/dl). Renal function did not improve despite fluid therapy. Hemodialysis was thus started on April 18. Thereafter, the uric acid level decreased but urine volume showed no improvement and his general condition gradually deteriorated. The biopsy results allowed a diagnosis of small-cell carcinoma, suggesting that the nodular shadow noted in the right lung represented the primary Clomifene tumor. Treatment

was judged to be difficult in view of his general condition, and the patient was followed without active treatment. He died on April 23. Conclusion: We thus encountered a case of tumor lysis syndrome probably arising from autolysis of small-cell lung carcinoma and an associated metastatic hepatic lesion.

Traditionally, naive and memory cells are characterized ex vivo b

Traditionally, naive and memory cells are characterized ex vivo by their mutually exclusive expression of CD45RA and CD45RO molecules, respectively. However, it is known that upon activation and proliferation in vitro naive T lymphocytes first acquire the expression of CD45RO and subsequently lose the expression of CD45RA, making the timing of the analysis of CD45 molecule expression in vitro critically important [23]. Nevertheless, it can be assumed that the percentage of CD4+CFSElow cells with the CD45RA-CD45RO+ phenotype also reflects

more or less accurately the frequency of memory cell-derived antigen-specific precursor T cells in our experimental system. Therefore, based on our data it KU-57788 order seems that in children with CD CD4+ T cells specific to gTG have mainly a memory phenotype, whereas Selleck R428 in healthy children these cells are more predominantly of naive origin. Consequently, in children with CD the stronger proliferative responses observed to gTG also presumably reflect the higher

frequency of memory CD4+ T cells specific to gTG in vivo. We also examined the expression of the gut-homing β7 integrin and observed that gTG-specific T cells expressed high levels of the molecule. This finding suggests that the CD4+ T cells specific to gTG are generated in the gut mucosa and are capable of trafficking back to the intestine. The specificity of the increased β7 integrin expression by gTG-specific T cells was demonstrated by a considerably lower expression of the molecule by TT-specific T cells that are primed by subcutaneous injections and thus lack the capacity to traffic to the gut. Our current results corroborate earlier reports demonstrating the

expression of β7 integrin by CD4+ T cells specific to gTG [12,14]. In conclusion, we have shown that CD4+ T cells specific to gTG are detectable in the peripheral blood of more than half of children with newly diagnosed CD, whereas this was significantly less common among buy AZD9291 healthy control children. In contrast, the responses to native gliadin did not differ between children with CD and healthy controls. We also demonstrate that in children with CD the CD4+ T cells specific to gTG have a memory cell phenotype and express β7 integrin as a marker of gut homing. Taken together, our results support the widely accepted model for the importance of T cell responses to gTG epitopes in the pathogenesis of CD. Moreover, further development of assays to detect specific CD4+ T cell responses to gTG in the peripheral blood may also have practical applications for the diagnostics of the disease, as demonstrated recently by HLA-tetramer staining in patients with uncertain CD [24]. We thank Virpi Fisk for the skilful technical assistance. The study was supported financially by the Finnish Cultural Foundation, the Finnish Coeliac Society and the Finnish Medical Foundation.

Rituximab® was used in the concentration 0·1 μg/ 0·2 × 106 target

Rituximab® was used in the concentration 0·1 μg/ 0·2 × 106 target cells. After counting and centrifugation

(200 g, 10 min) the target cells were adjusted to 2 × 106 cells/ml AIM-V medium. Ten μl antibodies were added to 0·2 × 106 target cells (0·1 ml) and incubated for 15 min at room temperature. The effector cells were counted and resuspended in AIM-V to a final concentration of 2 × 106 cells/ml; 0·2 × 106 of these cells were added to the antibody-coated target cells and after centrifugation (30 g for 3 min) the cells were incubated in a humidified incubator with 5% CO2 at 37°C for 2 h. After one wash in phosphate-buffered saline (PBS) the cells were ready for staining with the monoclonal antibodies given below and subsequent flow cytometry. Samples were labelled with monoclonal antibodies for 30 min in the dark at 4°C, washed once in PBS (pH 7·4) and finally resuspended Romidepsin in PBS. The following monoclonal mouse antibodies and other markers were used: anti-CD3 fluorescein isothiocyanate (FITC) (clone UCHT1, IgG1, F0818; Dako, Glostrup, Denmark), anti-CD56 phycoerythrin (PE) [clone c5·9, immunoglobulin (Ig)G2b, R7251; Dako], anti-CD107a Alexa 647 (clone eBio H4A3, IgG1, #51-1079; eBioscience, San Diego, CA, USA), anti-CD8 PC7 (clone SFCI21Thy2D3, IgG1, #737661; Beckman Coulter, Indianapolis, IN, USA), CD2/CD2R (CD2 clone L303·1,CD2R clone L304·1; #340366; BD Pharmingen, San Jose, CA, USA), AlexaFluor 647 mouse IgG1k isotype

control (clone MOPC-21, #557714; BD Pharmingen) and 7-aminoactinomycin D (7-AAD) (# 555816; BD Via Probe, BD Pharmingen). Flow cytometric analyses were performed using a Cytomics FC500 five-colour flow cytometer Napabucasin (Beckman Coulter) equipped with two lasers, an argon laser (488 nm) and a HeNe laser (633 nm). FlowJo software version 9·3 (Tree Star, Inc., Ashland, OR, USA) was used for data analysis. A total of 20 000 events were collected for further analysis. NK cells were defined as CD3−/CD56+ lymphocytes. Effector cells alone were used to define the initial CD107a level of positive NK cells or CD8+ cells. In Fig. 1,

we present examples of spontaneous up-regulation of CD107a on effector cells, as well as FMO (fluorescence-minus one), an isotype antibody control for CD107a and 7AAD viability staining. Using the CD2/CD2R system, we also performed positive effector cell control experiments, confirming the Ribonucleotide reductase activation potential of the effector cells (data not shown). In 51Cr cytotoxicity assays results are given normally as percentages of cell killing, with the maximum killing as a basic value. In assays measuring granularity by CD107a this is not meaningful, as a maximum value is difficult, if not impossible, to give. The results are therefore given as increments, where either the NK value or the value with preimmune serum is subtracted from the value with immune serum. The increase can also be given as a ratio between, for example, immune sera and preimmune sera.

In order to perform Western blot assays, HC– and SSc–MSC cells we

In order to perform Western blot assays, HC– and SSc–MSC cells were pelleted, washed twice with PBS, lysed on ice in lysis buffer (1% Triton X-100, 0·5% NP-40, 50 mM Tris–Cl, pH 7·5, 150 mM NaCl, 1 mM EDTA, supplemented with 1 mM phenylmethylsulfonyl fluoride, 1 mM NaF, 1 mM Na3VO4, 5 μg/ml aprotinin, 5 μg/ml leupeptin) for 30 min and cleared by centrifugation. The protein concentration was calculated by Bradford protein assay reagent (Bio-Rad, Hercules,

CA, USA). A 12% sodium dodecyl sulphate (SDS)-polyacrylamide gel electrophoresis (PAGE), under reducing conditions, was loaded with equal amount of proteins. All the loaded proteins were electrophoresed and then transferred to nitrocellulose Sirolimus supplier membranes C59 wnt (Amersham Pharmacia Biotechnology, Piscataway, NJ, USA). After 1 h blocking at room temperature in blocking buffer [5% non-fat milk in Tris-buffered saline/1% Tween 20 (TBS/T)] and after washing three times for 5 min each in TBS/T, the membranes were incubated overnight at 4°C with the primary antibodies: p53 [DO-1-mouse monoclonal antibody (mAb); Santa Cruz Biotechnology, Santa Cruz, CA, USA], p21 (Waf1/Cip1-DCS60-mouse mAb; Cell Signaling, Danvers, MA, USA), diluted in 5% bovine

serum albumin in TBS/T. Following three washes with TBS/T, horseradish peroxidase-conjugated secondary antibody (Santa Cruz Biotechnology) diluted in blocking buffer was added for 30 min at room Interleukin-2 receptor temperature and washed three times with TBS/T. The

detection was performed by enhanced chemiluminescence detection (ECL) reaction (Amersham Pharmacia Biotechnology). All the signals were quantified by normalizing to the tubulin signal (CP06 anti-α-tubulin mouse mAb-DM1A). Total RNA was extracted from normally cultured, doxorubicin-treated and MSC co-cultured with peripheral blood mononuclear cells (PBMC) using Trizol (Sigma) reagent and reverse-transcribed into complementary DNA (cDNA) using ThermoScript reverse transcription–PCR kit (Invitrogen, San Diego, CA, USA). The qRT–PCR was performed using SYBR green kits (Applied Biosystems, Life Technologies distributors, Paisley, UK). Primers were designed on the basis of the reported sequences (PrimerBank NCBI; p21: 5′-TGGAGACTCTCAGGGTCGAAA-3′ (forward) and 5′- TCTACCACTCCAAACGCCG-3′ (reverse); p53: 5′-CCAGGGCAGCTACGGTTTC-3′ (forward) and 5′-CTCCGTCATGTGCTGTGACTG-3′ (reverse); β-actin: 5′- CCTGGCACCCAGCACAAT-3′ (forward) and 5′-AGTACTCCGTGTGGATCGGC-3′ (reverse); TGFβ: 5′-CTAATGGTGGAAACCCACAACG-3′ (forward) and 5′-TATCGCCAGGAATTGTTGCTG-3′ (reverse); and IL-6: 5′-AATTCGGTACATCCTCGAGGG-3′ (forward) and 5′-TTGGAAGGTTCAGGTTGTTTTCT-3′ (reverse). Ki67 and GAPDH gene expressions were assessed by commercial Taqman gene expression assay (assay ID: Hs01032443_m1; Hs02758991_g1, respectively). The RT–PCR was run in triplicate. Results were analysed after 40 cycles of amplification using the ABI 7500 Fast Real-Time PCR system.
