Objective　To explore the molecular mechanism underlying the decreased velocity of tension rise in rat myocardium during congestive heart failure (CHF) and left ventricular hypertrophy (LVH) induced by aortic stenosis. Methods　The maximum velocity of tension rise (+dT/dtmax) was measured in left ventricular papillary muscle and the mRNA level of myosin heavy chain (MHC) isoforms in the left ventricle were detected by Northern blot analysis. Results　The value of +dT/dtmax in CHF and LVH group were 64.17% and 37.15% lower than sham-operated controls (Sham) (P<0.01); values in the CHF group were 42.99% lower than that of LVH (P<0.01). The level of α-MHC mRNA in LVH was not different from that of the Sham (P>0.05), but decreased significantly in CHF to 42.3% of Sham and 56.1% of LVH (P<0.01). The level of β-MHC mRNA was up-regulated by 88.3% (P<0.01) in LVH compared with Sham and the level of β-MHC in CHF was 1.5-fold and 3.7-fold higher than that in LVH and Sham respectively (P<0.01). The ratio of α-MHC/β-MHC mRNA in LVH and CHF decreased to 42.4% and 9.8% respectively of the value in Sham (P<0.01). Correlation between α-MHC/β-MHC mRNA level and +dT/dtmax was analyzed which showed that these values were positively correlated with a correlation coefficient of 0.875 (P<0.01). Conclusion　The decreased ratio of α-MHC/β-MHC mRNA was the major molecular mechanism underlying the decreased +dT/dtmax in CHF and LVH myocardium. The decreased ratio of α-MHC/β-MHC mRNA in LVH was mainly due to the up regulation of β-MHC mRNA while in CHF both down regulation of α-MHC and up regulation of β-MHC were involved.

BACKGROUND:The regulatory role of extracellular signal regulated kinase 1/2 (ERK1/2) and nuclear factor kappa B (NF-κB) signal pathways in the osteogenic differentiation of MC3T3-E1 cells subjected to mechanical strain remains unclear.
OBJECTIVE:To investigate the effects of ERK1/2 and NF-kB signal pathway on alkaline phosphatase, type Ⅰcol agen, osteocalcin and interleukin-6 expression in osteoblasts in response to mechanical strain, and to explore the regulatory effects of ERK1/2 and NF-kB signal pathway on osteoblast differentiation.
METHODS:MC3T3-E1 cells cultured in vitro were separately treated with ERK1/2 pathway specific inhibitor PD098059 and NF-kB pathway inhibitor PDTC for 30 minutes, and subjected to12%elongation for 24 hours. Normal cells and cells along loading 12%mechanical strain for 24 hours were considered as controls. Enzyme linked immunosorbent assay and real-time PCR were utilized to detect alkaline phosphatase activities, type Ⅰcol agen, osteocalcin and interleukin-6 mRNA expression before and after cellloading.
RESULTS AND CONCLUSION:Under 12%mechanical strain, alkaline phosphatase, type I col agen, and interleukin-6 expression was regulated by ERK1/2 signal pathway in MC3T3-E1 cells, but osteocalcin gene expression was not affected by ERK1/2 pathway. NF-kB signal pathway inhibitor PDTC significantly suppressed alkaline phosphatase activities in MC3T3-E1 cells under mechanical strain, and inhibited interleukin-6 gene expression. However, type I col agen and osteocalcin gene expression was not affected by NF-kB signal pathway. Results suggested that mechanical strain affected osteogenic differentiation and relevant gene expression in MC3T3-E1 cells by ERK1/2 and NF-kB signal pathway.
