Adipose (fat) tissues contain white, brown, and beige adipocytes. White adipocytes store extra energy in the form of lipids; ectopic and excessive accumulation of white adipose in the body leads to overweight and obesity, which often causes insulin resistance and Type 2 diabetes. Brown adipocytes, in contrast, contain hundreds of mitochondria per cell, dissipate energy into heat, and are negati...
The precise control of neuronal migration and morphological changes during differentiation is essential for neocortical development. We hypothesized that the transition of progenitors through progressive stages of differentiation involves dynamic changes in levels of mitochondrial reactive oxygen species (mtROS), depending on cell requirements. We found that progenitors had higher levels of mtR...
Genetic factors are important for the development of sarcopenia, a geriatric disorder characterized by low lean body mass. The aim of this study was to search for novel genes that regulate lean body mass in humans. We performed a large-scale search for 250K single-nucleotide polymorphisms (SNPs) associated with bone mineral density (BMD) using SNP arrays in 1081 Japanese postmenopausal women. W...
Heterochromatin serves important functions, protecting genome integrity and stabilizing gene expression programs. Although the Suv39h methyltransferases (KMTs) are known to ensure pericentric H3K9me3 methylation, the mechanisms that initiate and maintain mammalian heterochromatin organization remain elusive. We developed a biochemical assay and used in vivo analyses in mouse embryonic fibroblas...
Gene trap mutagenesis is a powerful tool to create loss-of-function mutations in mice and other model organisms. Modifications of traditional gene trap cassettes, including addition of conditional features in the form of Flip-excision (FlEx) arrays to enable directional gene trap cassette inversions by Cre and Flpe site-specific recombinases, greatly enhanced their experimental potential. By ta...
Prostate cancer (PCa) is one of the most prevalent malignant tumors. The alternation microRNA (miRNA) expression associated with prostate progression, whereas its way to influence progression remains elusive. levels PRDM16 mRNA and miR-372-3p in PCa cell lines were analyzed using qRT-PCR. protein was also western blot. CCK-8, wound healing, Transwell assays applied examine proliferation, migrat...
As a zinc-finger protein, PR domain containing 16 (PRDM16) controls brown fat determination by stimulating brown fat cell production while suppressing the expression of genes for production of white fat cells; mutations in this domain are associated with myelodysplastic syndrome and leukemogenesis. In our study, polymorphisms in exons 2, 3, 4, 5, 7, 8, and 9 of the PRDM16 gene were detect...
A clear relationship exists between visceral obesity and type 2 diabetes, whereas subcutaneous obesity is comparatively benign. Here, we show that adipocyte-specific deletion of the coregulatory protein PRDM16 caused minimal effects on classical brown fat but markedly inhibited beige adipocyte function in subcutaneous fat following cold exposure or β3-agonist treatment. These animals developed ...
مطالعات گذشته، اثر تمرین هوازی تداومی (CAT) را بر بیان ژن «پروتئین دارای منطقۀ تنظیمی مثبت 16» (PRDM16) در بافت چربی سفید بررسی کرده‌اند. با این حال، تاکنون مطالعه‌ای اثر انواع مدل‌های تمرینی به‌ویژه تمرین تناوبی شدید (HIIT) را بر بیان این ژن مطالعه نکرده است. بنابراین، در این مطالعه، اثر دو شیوۀ تمرین هوازی تداومی (CAT) و همچنین دو شیوۀ تمرین تناوبی شدید (HIIT) بر بیان این ژن بررسی شد. 40 سَ...
Transcriptional cofactors are essential to the regulation of transforming growth factor beta (TGFbeta) superfamily signaling and play critical and widespread roles during embryonic development, including craniofacial development. We describe the cleft secondary palate 1 (csp1) N-ethyl-N-nitrosourea-induced mouse model of non-syndromic cleft palate (NSCP) that is caused by an intronic Prdm16 spl...
