BACKGROUND: As a primary clinical predictor of fracture risk, bone mineral density (BMD) is partly genetically determined. Osteoprotegerin (OPG) is one important candidate gene in the pathogenesis of osteoporosis. OBJECTIVE: To investigate the association between T245G polymorphisms in the OPG gene and BMD. METHODS: A total of 281 elderly men and postmenopausal women, 182 males and 99 females, who received routine examinations at Peking University People's Hospital between September 2008 and April 2010 were included in this study. T245G polymorphisms in the OPG gene was detected by polymerase chain reaction-restriction fragment length polymorphism together with DNA sequencing. The BMD of the lumbar spine, Ward's triangle, and forearrm was determined by dual energy X-ray absorptiometry. Clinical variables and biochemical measurements were collected simultaneously. The association between T245G polymorphisms and each detection index was analyzed using analysis of variance. RESULTS AND CONCLUSION: The distribution of T245G genotype (alleles T, G) had no difference in elderly men or postmenopausal women (P > 0.05). The GG genotype and TG genotype had higher lumbar spine BMD and TT genotype had lower lumbar spine BMD (P < 0.05). There was no difference in BMD of the Ward's triangle or forearm among different genotypes (P > 0.05). Association between T245G polymorphism and BMD was not found in postmenopausal women. These findings indicate that OPG gene is related to lumbar spine BMD in elderly men.

OBJECTIVETo investigate the effects and mechanisms of high glucose on the phenotype transformation of rat vascular smooth muscle cells (VSMCs).
METHODSVSMCs ere isolated from rat thoracic aorta and the 3rd-5th VSMCs were incubated with normal glucose (5.5 mmol/L), high glucose (25 mmol/L), or high glucose (25 mmol/L) + P38 inhibitor (25 mmol/L +SB203580) for another 24 hours. Then the gene expression of osteopontin (OPN), alpha smooth-actin (alpha-SMA), matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9(MMP-9) were assayed by real time RT-PCR, the protein expression of P38 were assayed by Western blot.
RESULTS(1) High glucose promoted the phenotype transformation of VSMCs and up-regulated the expression of MMP-2 and MMP-9. (2) High glucose promoted the phosphorylation of P38. (3) SB203580, the inhibitor of P38/MAPK signal pathway, inhibited the effects of high glucose on phenotype transformation and expression of MMP-2 and MMP-9.
CONCLUSIONHigh glucose may promote phenotype transformation of VSMCs via the signal pathway of P38/MAPK.

AIM: To identify the down-regulated genes in adult rat cardiac fibroblasts (CF) stimulated with angiotensin Ⅱ (AngⅡ). METHODS: Suppression subtractive hybridization (SSH) was performed between the CF stimulated by AngⅡ (driver) and unstimulated CF (tester) to generate subtractive cDNA library. The library was screened with dot blots hybridization to further verify the differentially expressed cDNA clones. Partial positive clones were sequenced and BLAST analyzed. RESULTS: Seventeen down-regulated genes related to intracellular signal transduction, transcriptional repression, deposition of fibrous matrix and cellular cytoskeletal rearrangement, and 4 new expression sequence tags (EST) were acquired. CONCLUSION: SSH is a powerful technique with high sensitivity for the detection and clone of down-regulated genes expressed in CF induced by AngⅡ, which is helpful to clarify the mechanism of cardiac remodeling.
