AI Technical Summary

Benefits of technology

The present invention provides a peptide molecule called Ala-Hyp-Gly, Hyp-Gly-Pro, Leu-Hyp, Glu-Hyp, Gly-Pro-Hyp, Pro-Ala, Hyp-Gly, and Pro-Hyp that can promote the differentiation of myoblasts, which are a type of muscle cell. This peptide is more effective than previous methods and can be used to develop better treatments for muscle disorders.

Problems solved by technology

However, whether these peptide molecules have a myoblast differentiation promoting effect has not been known.

Abstract

A peptide selected from the group consisting of Ala-Hyp-Gly, Hyp-Gly-Pro, Leu-Hyp, Glu-Hyp, Gly-Pro-Hyp, Pro-Ala, Hyp-Gly and Pro-Hyp, or a pharmaceutically acceptable salt thereof has a myoblast differentiation promoting effect superior to conventional arts.

Description

TECHNICAL FIELD[0001]The present invention relates to a myoblast differentiation promoter comprising peptide molecule(s) or the like.BACKGROUND ART[0002]Recently, prevention and the like of locomotive syndrome and sarcopenia (reductions in muscle quantity and muscle strength, and decrease in physical function) attract attentions, and it is demanded to ameliorate such symptoms by increases in muscle quantity and muscle strength. Also for healthy persons, prevention of muscular fatigue and enhancement of muscle are demanded.[0003]In an initial process of muscle cell differentiation, an undifferentiated cell differentiates into a myoblast which is a cell derived from a muscle fiber. The myoblast further differentiates, and a protein that is specific to a muscle cell is expressed. A phenomenon characteristic of differentiation of a muscle cell is cell fusion, i.e., a phenomenon that myoblasts which are mononuclear cells fuse to differentiate into a myotube cell which is a multinucleate ...
