“Objective: To investigate the antitumor activity of metformin combined with valproic acid (VPA) on renal cell carcinoma

(RCC) cell lines. Methods: The effects of metformin combined with VPA on the viability of 786-O and caki-2 cell lines were evaluated by MTT assay. The inhibitory effect of combination of the two drugs was analyzed by the Chou and Talalay method. BIBF 1120 clinical trial Flow cytometry was employed to analyze cell cycle and cell apoptosis. Results: MTT assay showed that both metformin and VPA decreased 786-O and Caki-2 cells viability in a dose-dependent and time-dependent manner. In 786-O cells, metformin combined with VPA had a synergistic inhibitory effect (CI GSK461364 mw smaller than 1) when the inhibition effect was bigger than = 0.3. In Caki-2 cells, metformin combined with VPA had a synergistic inhibitory effect (CI smaller than 1) when the inhibition effect was bigger than = 0.4. Metformin and VPA combination elicited significant apoptosis compared to drug used alone (P smaller than 0.05). Furthermore, metformin and VPA acted synergistically to arrest 786-O and Caki-2 cells in G(0)/G(1) phase. Conclusion: We highlighted for the first time that metformin combined with VPA could significantly increase anti-ccRCC effect through synergetic effect; its possible mechanisms were inducing apoptosis and adjusting cell cycle.”

acetic acids (6) and 5-arylidene-4-oxo-2-thioxothiazolidines (7), which we recently synthesised and assayed as aldose reductase inhibitors, were evaluated as anti-inflammatory/antidegenerative agents in cultures of human chondrocytes stimulated by IL-1 beta. In this screening, most of the tested compounds were able to control key components of the IL-1 beta-induced inflammatory signalling, by reducing the levels of NF-kB, ICAM-1, and NO as well as increasing the production of glycosaminoglycans by chondrocytes. Moreover, these 4-thiazolidinone derivatives exhibited

BMS-754807 antioxidant properties and were shown to inhibit MMP-3 and MMP-13 at micromolar concentrations, with a generally marked preference toward MMP-13 which plays a major role in cartilage degeneration. Thus, on the whole, compounds 6 and 7 were shown to be capable of both counteracting inflammatory events and contributing to restore normal levels of cartilage components. This anti-inflammatory/antidegenerative profile makes them interesting cell-permeable molecules that can be assumed as lead compounds in the search for novel anti-inflammatory agents.”
“The aim of this article is to assess the potential relationships between TNF alpha gene promoter methylation in peripheral white blood cells and central adiposity (truncal fat), metabolic features and dietary fat intake. A group of 40 normal-weight young women (21 +/- 3 y; BMI 21.0 +/- 1.7 kg/m(2)) was included in this cross-sectional study.
