Description
Prenatal exposure to valproic acid, an established anti-epileptic drug, has been reported to impair postnatal cognitive function of children from epileptic mothers. Nevertheless, its pathology and proper treatment to minimize the effects remain unknown. In mice, we found that the postnatal cognitive function impairment was mainly caused by a reduction of adult neurogenesis and abnormal neuronal features in the hippocampus, which could be ameliorated by voluntary running.

Description
Estrogen clearly prevents osteoporotic bone loss by attenuating bone resorption. The molecular basis of how this is accomplished, however, remains elusive. Here we report a critical role of osteoclastic ERa in mediating estrogen action on bone in females. We selectively ablated ERa in differentiated osteoclasts (ERa dOc/dOc). ERa dOc/dOc females, but not males, exhibited clear trabecular bone loss, similar to the osteoporotic bone phenotype in post-menopausal women. Recovery of bone loss by estrogen treatment of the ovariectomized ERa dOc/dOc females was ineffective in the trabecular areas of the long bones and lumbar vertebral bodies. Osteoclastic apoptosis, induced by estrogen, occurred simultaneously with up-regulation of Fas ligand (FasL) expression in intact trabecular bones of ERa +/+mice, but not in ERa dOc/dOc mice. ERa was also required for similar effects of estrogen and tamoxifen in cultured osteoclasts. These findings suggest that the osteoprotective actions of estrogen and SERMS are mediated at least in part through osteoclastic ERa in trabecular bone; and the life span of mature osteoclasts is regulated through activation of the Fas/FasL system.

Description
Bisphenol A (BPA), an endocrine-disrupting chemical (EDC), is a well-known, ubiquitous estrogenic chemical. To investigate the effects of fetal exposure to low-dose BPA on the development of the prostate, we first examined the alterations of in situ sex steroid hormonal environment in the mouse urogenital sinus (UGS).

Description
Rett syndrome (RTT) is a devastating neurodevelopmental disorder that occurs once in every 10,000-15,000 live female births. Despite intensive research, no effective cure is yet available. Valproic acid (VPA) has been used widely to treat mood disorder, epilepsy, and a growing number of other disorders. In limited clinical studies, VPA has also been used to control seizure in RTT patients with promising albeit somewhat unclear efficacy. In this study we tested the effect of VPA on the neurological symptoms of RTT and discovered that short-term VPA treatment during the symptomatic period could reduce neurological symptoms in RTT mice. We found that VPA restores the expression of a subset of genes in RTT mouse brains, and these genes clustered in neurological disease and developmental disorder networks. Our data suggest that VPA could be used as a drug to alleviate RTT symptoms.

Description
Exosomes are small membrane vesicles (30-100 nm in diameter) secrted by numerous cells. Exosome have been shown to contain mRNA and DNA. We found at least two types of salivary exosomes (exosome I and exosome II) that are different in size and have different proteome. In previous study, we performed small RNA transcriptome analysis by next generation sequencing technology and reported that many types of small RNA, such as miRNA, piwi-interacting RNA (piRNA), small nucleolar RNA (snoRNA), other small RNAs and genomic repeats were contained in exosome I, II and whole saliva. In this study, we performed whole-transcriptome analysis using cDNA libraries constructed from total RNA except small RNAs. We found that 11-32% of reads from salivary exosomes and whole saliva were mapped to pseudogene. The Data Access Committee of the National Bioscience Database Center (NBDC) approved that this personal genetic data were made published according to NBDC data sharing guidelines (http://humandbs.biosciencedbc.jp/).

Description
To explore the potential targets of Bmi1 in the liver development of hepatic carcinogenesis, we assayed the gene expression level in the liver of Bmi1 knockout mice. We isolated the liver tissue of Bmi1 WT and KO mice around 6-8 weeks. Then we extracted total RNA and run the microarray detection. Gene expression in Bmi1 KO mouse livers was compared with that in Bmi1 WT mouse livers to screen potential targets of Bmi1.
