The urinary albumin excretion rate and prevalence of microalbuminuria were higher in isolated-impaired glucose tolerance subjects than those in isolated-impaired fasting glycaemia subjects. At early abnormal glucose tolerance stage, the increasing post-challenge glycaemia might be a more important risk factor for urinary albumin excretion rate and microalbuminuria than increasing fasting glycaemia.

HoxD10 gene plays a critical role in cell proliferation in the process of tumor development. However, the protein expression level and the function of HoxD10 in prostate cancer remain unknown. Using tissue microarray, we demonstrate that the protein expression of HoxD10 is commonly decreased in prostate cancer tissues (n = 92) compared to adjacent benign prostate tissues (n = 77). Functionally, knockdown of HoxD10 resulted in significant promotion of prostate cancer cell proliferation. Moreover, knockdown of HoxD10 strikingly stimulated prostate tumor growth in a mouse xenograft model. We also found a significant association between decreased immunohistochemical staining of HoxD10 expression and higher Gleason score (P = 0.031) and advanced clinical pathological stage (P = 0.011). An analysis of the Taylor database revealed that decreased HoxD10 expression predicted worse biochemical recurrence (BCR)-free survival of PCa patients (P = 0.005) and the multivariate analyses further supported that HoxD10 might be an independent predictor for BCR-free survival (P = 0.027). Collectively, our data suggest that the loss of HoxD10 function is common and may thus result in a progressive phenotype in PCa. HoxD10 may function as a biomarker that differentiates patients with BCR disease from the ones that are not after radical prostatectomy, implicating its potential as a therapeutic target.

ABSTRACT. The purpose of this study was to evaluate single nucleotide polymorphism (SNP) variants of the estrogen receptor 1 gene (ESR1) at rs2234693 and rs9340799, as well as to investigate the relationship between ESR gene polymorphisms and postmenopausal osteoporosis (OP) of the spine in Chinese women. We recruited 198 postmenopausal women with OP and 276 healthy women between May 2012 and September 2015 in Zhongshan Hospital. Dual energy x-ray absorptiometry was used to measure the bone mineral density (BMD) of the lumbar vertebrae in all subjects. In addition, PCR-restriction fragment length polymorphism based analysis was conducted to identify the genotypes of ESR1. The distribution of ESR1 in the osteoporosis group and the control group was determined; the relationship between ESR polymorphisms and BMD was analyzed. The distributions of BMD were: TT < TC < CC, GG < AG < AA. The TT, TTGG, and TCGG genotypes were found to be lower as compared to the other genotypes. Stratified analysis suggested that the TT genotype and the combined genotypes TTGG and TCGG were significantly higher in the OP group as compared to the control group (P < 0.01). Therefore, ESR1 polymorphisms at rs2234693 and rs9340799 may be associated with OP, and could be used as markers to screen those with high risks to postmenopausal OP in Chinese women.
