AIM: Thiazolidinediones (TZD) are a new class of oral antidiabetic drugs that have been shown to inhibit growth of same epithelial cancer cells. Although TZD were found to be ligands for peroxisome proliferator-activated receptor γ (PPARγ), the mechanism by which TZD exert their anticancer effect is presently unclear. In this study, we analyzed the mechanism by which TZD inhibit growth of human pancreatic carcinoma cell lines in order to evaluate the potential therapeutic use of these drugs in pancreatic adenocarcinoma. METHODS: The effects of TZD in pancreatic cancer cells were assessed in anchorage-independent growth assay. Expression of PPARy was measured by reverse-transcription polymerase chain reaction and confirmed by Western blot analysis. PPARy activity was evaluated by transient reporter gene assay. Flow cytometry and DMA fragmentation,assay were used to determine the effect of TZD on cell cycle progression and apoptosis respectively. The effect of TZD on ductal differentiation markers was performed by Western blot. RESULTS: Exposure to TZD inhibited colony formation in a PPARγ-dependent manner. Growth inhibition was linked to G1 phase cell cycle arrest through induction of the ductal differentiation program without any increase of the apoptotic rate. CONCLUSION: TZD treatment in pancreatic cancer cells has potent inhibitory effects on growth by a PPAR-dependent induction of pacreatic ductal differentiation.

AIM To build a regional database of chronic patients to define the clinical epidemiology of hepatitis B virus(HBV)-infected patients in the Tuscan public health care *** This study used a cross-sectional cohort design. We evaluated chronic viral hepatitis patients with HBV referred to the outpatient services of 16 hospital units. Information in the case report forms included main demographic data, blood chemistry data, viral hepatitis markers, instrumental evaluations, and eligibility for treatment or ongoing therapy and liver transplantation. RESULTS Of 4015 chronic viral hepatitis patients, 1096(27.3%) were HBV infected. The case report form was correctly completed for only 833 patients(64% males, 36% females; mean age 50.1 ± 15.4). Of these HBV-infected patients, 73% were Caucasian, 21% Asian, 4% Central African, 1% North African and 1% American. Stratifying patients by age and nationality, we found that 21.7% of HBV-infected patients were aged < 34 years(only 2.8% were Italian). The most represented routes of transmission were nosocomial/dental procedures(23%), mother-to-child(17%) and sexual transmission(12%). The most represented HBV genotypes were D(72%) and A(14%). Of the patients, 24.7% of patients were HBe Ag positive, and 75.3% were HBe Ag negative. Of the HBV patients 7% were anti-HDV positive. In the whole cohort, 26.9% were cirrhotic(35.8% aged < 45 years), and 47% were eligible for or currently undergoing treatment, of whom 41.9 % were cirrhotic. CONCLUSION Only 27.3% of chronic viral hepatitis patients were HBV infected. Our results provide evidence of HBV infection in people aged < 34 years, especially in the foreign population not protected by vaccination. In our cohort of patients, liver cirrhosis was also found in young adults.
