[Aging-related frailty and sarcopenia. Kampo medicine for frailty and sarcopenia.].

In Japan, which is entering a super-aged society, the prevention of long-term care and bedridden caused by frailty and sarcopenia have been recognized as an urgent need. The pathology of frailty and sarcopenia includes broad problems of senility. A traditional herbal medicine is known to improve symptoms across the organs, many herbal medicines administered by examining the balance of mind and body are effective for frailty and sarcopenia.

Maternal stress affects postnatal growth and the pituitary expression of prolactin in mouse offspring.

Maternal stress exerts long-lasting psychiatric and somatic on offspring, which persist into adulthood. However, the effect of maternal stress on the postnatal growth of pups has not been widely reported. In this study, we found that maternal immobilization stress (IS) during lactation resulted in low body weight of male mouse offspring, which persisted after weaning.

alphaB-crystallin: a novel p53-target gene required for p53-dependent apoptosis.

The p53 protein is a transcription factor that trans-activates various genes in response to DNA-damaging stress. To search for new p53-target genes, we applied a cDNA microarray system using two independent p53-inducible cell lines, followed by in silico analysis to detect p53 response elements. Here, we report on crystallin alpha B gene (CRYAB), which encodes alphaB-crystallin, and is one of the genes directly trans-activated by p53.
