Bone Abstracts

The gut microbiota (GM), the commensal bacteria living in our intestine, performs numerous useful functions, including modulating host metabolism and immune status. Our recent studies demonstrate that the GM is also a regulator of bone mass and we propose that the effect of the GM on bone mass is mediated via effects on the immune system, which in turn regulates osteoclastogenesis. A role of the GM in bone metabolism is further supported by studies demonstrating that antibioti...

It is well established that estrogen, mainly via estrogen receptor alpha (ERα), has positive effects on bone, but estrogen is not considered as a treatment option against osteoporosis due to negative side-effects in other tissues. ERα is widely subjected to posttranslational modifications (PTMs), which can affect cellular responses to estrogen in a tissue specific manner by influencing the function of ERα and its interactions with other proteins. The in vivo...
