AIM: To investigate the effects of fenofibrate on angiotensin Ⅱ ( AngⅡ)-induced cardiomyocyte hypertrophy .METHODS:Primary neonatal cardiomyocytes were pretreated with fenofibrate (10μmol/L) for 1 h followed by stimulation with AngⅡ(100 nmol/L).The mRNA levels of ANF, BNP andβ-MHC were measured by real-time PCR. Western blotting was employed to determine the nuclear translocations of NFATc 4 and p65-NFκB.Co-immunoprecipitation was used to investigate the interaction of NFATc 4 with p65-NFκB in the nucleus of cardiomyocytes .In addition, the DNA binding activity of NFATc4 on the BNP promoter was determined by EMSA .RESULTS:Fenofibrate significantly inhibited AngⅡ-induced cardiomyocyte hypertrophy .Fenofibrate treatment inhibited the nuclear translocations of NFATc 4 and p65-NFκB, as well as the interactions of NFATc 4 with p65-NFκB in the nucleus of cardiomyocytes induced by AngⅡ.Fenofi-brate inhibited the binding activity of NFATc 4 with the BNP promoter , which was strengthened by AngⅡ.CONCLU-SION:Fenofibrate enhances the interaction of NFATc 4 with PPARα, decreases the interaction of NFATc 4 with p65-NFκB in the nucleus of cardiomyocytes , and inhibits the DNA binding activity of NFATc 4 induced by AngⅡ, which may be the important mechanisms of fenofibrate on inhibiting cardiac hypertrophy .

OBJECTIVESTo detect aberrant p16 promoter methylation in serum of patients with colorectal cancer (CRC), and to explore the possibility of using this assay in early detection or as a prognostic marker.
METHODSMethylation-specific PCR was used to detect p16 methylation in DNA extracted from 52 CRCs and corresponding serum samples. Serum samples from 34 patients with adenomatous polyps and 10 healthy individuals were used as controls. The association of p16 hypermethylation in serum DNA of CRC patients with clinicopathological characteristics was analyzed.
RESULTSp16 methylation was found in 38% (20 of 52) of CRC tissues. Among the 20 patients with aberrant methylation in the tumor tissues, similar changes were also detected in the serum of 14 (70%) patients. No methylated p16 sequences were detected in the peripheral serum of the 32 CRC patients without these changes in the tumor, in 34 paitents with adenomatous polyps, or in 10 healthy controls. Clinicopathological analysis revealed that p16 methylation in serum was significantly associated with later Dukes' stage (chi(2) = 5.7, P = 0.03).
CONCLUSIONThis assay offers a potential means for the serum-based detection and/or monitoring of CRC patients.
