Revolutionary studies from Leipzig: GPR133 strengthens bones and muscles!

researchers from the University of Leipzig examined the role of the receptor GPR133 in bone structure. The results of this research, published in the renowned Nature Journal "Signal Transduction and Targeted Therapy", show promising approaches to the treatment of osteoporosis and to strengthen bones and muscles in old age. In Germany, about six million people, especially women, are affected by this bone loss.

GPR133 is a little researched adhesion g protein-coupled receptor, which activates both the bone-building cells (osteoblasts) and inhibits the bone-reducing cells (osteoclasts). In the case of mice, gene changes in the GPR133 lead to signs of bone loss, which underlines the importance of this receptor in bone health. The identification of the active ingredient AP503, which acts as a stimulator of GPR133, could offer revolutionary therapeutic possibilities. This showed that AP503 increases bone resistance in both healthy and osteoporotic mice.

research results and application potential

The study examines the mrNA expression of osteoblastic differentiation markers and the differences between different mouse lines, including wild types and various knockout variants. Methods such as measuring serum concentrations of type 1 Procollages AMINO terminal Prepeptide (P1NP) as a marker for bone formation and cross-link C-telopeptides of type I collagen (CTX) as a marker for bone absorption was obtained that regulate the bone structure and degrading balance.

outlook on future research

The University of Leipzig, which is internationally leading in the research of Adhäsions-G-protein-coupled receptors, is already planning further projects to deepen research on AP503 and GPR133. In the future, this work could enable decisive progress in treatment and possibly also to prevent osteoporosis. The potential that results from these findings could not only improve the life of millions of people affected, but also show new therapeutic paths in alternative medicine.
