Abstract Background As the incidence of secretory osteoporosis has increased, bone loss, osteoporosis and their relationships with thyroid-stimulating hormone (TSH) have received increased attention. In this study, the role of TSH in bone metabolism and its possible underlying mechanisms were investigated. Methods We analyzed the serum levels of free triiodothyronine (FT3), free thyroxine (FT4), and TSH and the bone mineral density (BMD) levels of 114 men with normal thyroid function. In addition, osteoblasts from rat calvarial samples were treated with different doses of TSH for different lengths of time. The related gene and protein expression levels were investigated. Results A comparison of the BMD between the high-level and low-level serum TSH groups showed that the TSH serum concentration was positively correlated with BMD. TSH at concentrations of 10 mU/mL and 100 mU/mL significantly increased the mRNA levels of ALP, COI1 and Runx2 compared with those of the control (P < 0.05, P < 0.01). Bone morphogenetic protein (BMP)2 activity was enhanced with both increased TSH concentration and increased time. The protein levels of Runx2 and osterix were increased in a dose-dependent manner. Conclusions The circulating concentrations of TSH and BMD were positively correlated with normal thyroid function in males. TSH promoted osteoblast proliferation and differentiation in rat primary osteoblasts.

Abstract Human genetic variants play major roles in predicting and prognosis of several diseases. The effect of rs58542926 variant in transmembrane 6 superfamily member 2 (TM6SF2) gene on liver fibrosis among patients with chronic hepatitis C (CHC) is still debatable. The aim of this study is to investigate the possible effects of this variant in CHC patients. The study comprised 351 subjects: 250 CHC patients with different fibrosis stages (F0-F4) and 101 healthy volunteers. TM6SF2 (rs58542926) genotype was determined for all subjects. Blood samples were collected for complete blood count and biochemical analysis and cohort subjects were genotyped for the variant TM6SF2 rs58542926. Fibrosis staging was performed using Fibrotest and Fibroscan standard tests. The presence of the minor allele was significantly associated with severe liver fibrosis, as well as thrombocytopenia as an extrahepatic alteration. In addition, there was a significant association between the minor allele and lower thrombopoietin levels. The association of TM6SF2 genotype with thrombocytopenia was explored by measuring plasma thrombopoietin (TPO) levels for CHC patients. The results showed an association with extrahepatic alteration (thrombocytopenia) through its effect on plasma TPO level, and consequently on platelets production, which raises questions about the role of this variant in HCV treatment outcome. In conclusion, the occurrence of the minor allele of the variant rs58542926 can be linked to severe fibrosis stages as well as thrombocytopenia, enabling this variant to be used as a diagnostic pharmacogenetic marker for predicting the risk of fibrosis onset in CHC patients.
