Cytokines as important playmakers of experimental hepatocarcinogenesis confounded by diabetes
Journal Title: Annals of Hepatology - Year 2012, Vol 11, Issue 1
Abstract
Purpose. To explore the possible intermediary pathways through which diabetes mellitus (DM) adversely worsens hepatocellular carcinoma (HCC), focusing on cell life controllers as some transcription factors and inflammatory mediators. Material and methods. Forty male albino rats were divided into four groups, control, cancer [given single intra-peritoneal (IP) dose of diethyl nitrosamine, NDEA, 125 mg/kg body weight], diabetic (given single dose of streptozotocin, STZ, 65 mg/kg) and cancer diabetic. HCC was initiated with NDEA, 3 weeks later, DM was induced with STZ. At 14th week, animals were sacrificed. Serum ALT, AST, GGT activities, AFP, IL-6, TNF-α levels and liver tissue Bax and Bcl2 proteins were measured. Liver sections were stained for histological examination. Both histological and AFP variations were chosen to prove cancer development. Results. NDEA group showed significant increase in liver weight, serum ALT, AST, GGT, AFP, TNF-α, IL-6 and liver Bcl2 protein with decrease in total body weight, liver Bax protein and Bax/Bcl2 ratio. These effects were more pronounced in DENA plus STZ group. IL-6, TNF-α and Bcl2 were positively correlated while Bax and Bax/Bcl2 ratio were negatively correlated to AFP levels reflecting potential diagnostic value. Conclusion. Co-induction of DM in the course of hepatocarcinogenesis can dramatically influence disease progression through inflammation and retarded apoptosis. The suggested apoptotic and inflammatory markers seem to be beneficial diagnostic tools for HCC and improve the diagnostic performance of AFP.

Direct-Acting Antiviral Therapy Outcomes in Canadian Chronic Hepatitis C Telemedicine Patients
Introduction. Many of the 300,000 HCV-infected Canadians live in under-served and remote areas without access to HCV healthcare specialists. Telemedicine (TM) and advances in HCV management can facilitate linkage of thes...
Novel cytochrome P450-2D6 promoter sequence variations in hepatitis C positive and negative subjects
Introduction. CYP2D6 is a liver enzyme that metabolizes more that 25% of drugs and thus may play a pivotal role in drug-drug interactions. The promoter sequences of cytochrome P450 2D6 (CYP2D6) gene could impact metaboli...
