Objective: The enzyme methylenetetrahydrofolate reductase (MTHFR) is known to play an important role in the removal of circulating homocysteine via the methionine cycle. C677T polymorphism is associated with higher plasma homocysteine levels, which could affect collagen maturation. The aim of the present study was to examine possible associations of C677T polymorphism in the MTHFR gene with a variability of femoral (F-BMD), spinal BMD (S-BMD) together with circulating...

It is well known that sex hormone deficiency leads to increased bone turnover and subsequent bone loss. The metabolism of estrogens involves, among others, oxidation (mainly hydroxylation) by CYPs. The aim of this study was to determine whether Leu432Val polymorphism in the CYP1B1 gene is present also in Slovak population and subsequently, if it is associated with femoral and spinal bone mineral density (FBMD and SBMD), bone remodeling markers and fracture incidence in this po...
