Opis:: Introduction: The pathogenesis of chronic hepatitis B depends on both, the immune response and oxidative stress. Aim of the study: To assess the hepatic expression of miR-122 and the antioxidant genes: HMOX-1, NQO1 and GFER1, in liver biopsy specimens obtained from patients with chronic hepatitis B, with regard to selected clinical and histological parameters, using RT-PCR. Results: The study group comprised 34 HBV-infected patients. Statistically significant associations were found between lower hepatic expression of HMOX-1 and greater severity of liver inflammation (p=0.04). However, significantly higher expression of NQO1 was observed in patients with advanced liver fibrosis (p=0.035). Hepatic expression of miR-122 in HBV patients was not associated with viral load or liver injury. Conclusion: The hepatic expression of HMOX-1and NQO1 may be associated with liver injuries in chronic hepatitis B. However, hepatic expression of miR-122 does not seem to correspond to progression of the liver disease.

Opis:: RUNX2 is a member of the PEBP2/CBF transcription factors family controlling the expression of genes whose products are essential for bone formation. Mutations in the RUNX2 gene may be associated with cleidocranial dysplasia (CCD), a rare skeletal disease characterized by stature aberrations, delayed closure of the cranial sutures, hypoplastic or aplastic clavicles, and multiple dental abnormalities. As RUNX2 is involved in many signaling pathways, we hypothesize that CCD may be associated with their changes. We determined the expression of RUNX2 and its signaling partners TCF7, involved in canonical Wnt signaling, and fibroblast growth factor receptors, FGFR1 and FGFR2 in periodontum of CCD patients and control individuals. We did not observe any differences between the level of RUNX2, TCF7 and FGFR1/2 mRNA, determined by real-time PCR, in CDD patients and controls. Therefore, RUNX2 signaling pathways with their partners TCF7 and FGFR1/2 may not be involved in CCD pathogenesis.

Opis:: Introduction. Hepatitis C virus (HCV) infection is a global health problem which can lead to liver cirrhosis or hepatocellular carcinoma in one-fifth of chronically infected patients. Materials and methods. The study group consisted of 123 patients: 90 with HCV mono- and 33 with HIV/HCV co-infection, who were treated with pegylated interferon alfa (Peg-IFN-α) and ribavirin. We analyzed selected pretreatment factors: age, sex, HIV/HCV co-infection, grade of inflammation, necrotic changes and fibrosis in histological analysis of liver bioptates, HCV viral load, HCV genotypes, and single nucleotide polymorphisms (SNPs) of IL28B and tried to find out which of them influence sustained virological response (SVR). The IL28B SNP C/T (rs12979860) was analyzed using Custom® SNP Genotyping Assays (Applied Biosystems). Results. Multivariate analysis demonstrated that after adjusting for the other variables three predictors independently influence SVR, namely genotype 3 of HCV, presence of the CC genotype and age >40 years (OR respectively 15.14, 3.62, and 0.36). HCV mono-infected patients were infected with HCV genotype 3 or 4 less frequently (p=0.0001) compared to HIV/HCV co-infected individuals. In patients with HIV/HCV co-infection the CC variant occurred more frequently whereas CT was found less frequently (p=0.001, p=0.0146, respectively). In patients with HIV/HCV co-infection, 3 and 4 genotype of HCV occurred more frequently compared to patients with HCV mono-infection (p=0.0001). Conclusions. These data suggest that age, HCV genotype and IL28B polymorphism are useful for prediction of the response to treatment with Peg-IFN-α and ribavirin. The more frequent occurrence of HCV genotypes 3 or 4 in patients with HIV/HCV co-infection could be associated with the route of transmission.

Opis:: Bronchial asthma is characterized by persistent airway inflammation and airway wall remodeling. Among many different cells and growth factors triggering changes in bronchi structure, transforming growth factor β1-induced fibroblast to myofibroblast transition is believed to be very important. The aim of this study was to evaluate whether theophylline (used in asthma therapy) and two other methylxanthines (pentoxifylline and its active metabolite lisofylline), may affect transforming growth factor β1-induced fibroblast to myofibroblast transition in bronchial fibroblasts derived from asthmatic patients. We show here for the first time that selected methylxanthines effectively reduce transforming growth factor β1-induced myofibroblast formation in asthmatic bronchial fibroblast populations. PTX was found to be the most effective methylxanthine. The number of differentiated myofibroblasts after PTX, LSF and THEO administration was reduced at least twofold. Studies on the use of methylxanthines opens a new perspective in the development of novel strategies in asthma therapy through their two-pronged, anti-inflammatory and anti-fibrotic action. In the future they can be considered as promising anti-fibrotic drugs.
