Studies indicate that proteins of hepatitis C virus (HCV) disturb expression of cell-cycle-related proteins. A disturbed cell-cycle control is a hepatocellular carcinoma (HCC) risk factor in patients with HCV-related liver damage. The present study aimed to analyse the cellular expression of p21/Wafl/Cipl (p21) in long-lasting chronic hepatitis C (CH-C),(More)
Interleukin 2 (IL-2), or T-cell growth factor (TCGF), represents the first identified, fully-characterized, purified human interleukin. It is produced mainly by T helper (CD4+) lymphocytes, stimulates cell-mediated immune responses, controls growth and differentiation of B lymphocytes, and intensifies proliferation and activity of all cytotoxic cell clones.(More)
Hepatitis C virus (HCV) continues to represent the main causative agent of the hepatitis, which leads to chronic transformation of the process in 60-80% individuals. It remains unclear how far cellular expression of HCV proteins in vivo may represent an index of progression of the disease and of proliferative activity in the liver in chronic hepatitis C.(More)
The results of presented study demonstrate expression of ghrelin, its functional receptor GHSR-1a and their genes in spermatogenic cells of rat testis suggesting their functioning within seminiferous epithelium. The immunohistochemical and hybrydocytochemical expression, of proteins and transcripts, was estimated taking into account the cycle of(More)
In view of the unclear prognostic and diagnostic role of interleukin 2 (IL-2) and its receptor in human tumours, we examined the cellular expression of IL-2 and of the subunit alpha of its receptor (IL-2Ralpha, CD25) in relation to the proliferative activity of various subtypes of lung tumours. The immunocytochemical ABC technique was applied to archival(More)
Chronic infection with hepatitis C virus (HCV) is regarded as a risk factor for hepatocellular carcinoma (HCC), mostly in patients with liver cirrhosis. Present study aimed at evaluation of cellular expression of p53 protein, genetic TP53 changes in liver samples and anti-p53 in serum of patients with chronic hepatitis C virus infection. The expression of(More)
