Establishing preadipocyte cell lines from mature adipose tissues could help lead to a better understanding of adipogenesis. We have established a unique preadipocyte cell line, AP-18, derived from the subepidermal layer of ear skin from an adult C3H/HeM mouse. AP-18 cells exhibit fibroblast-like morphology, slow growth, and contact inhibition. The doubling time of AP-18 cells is 50-60 h, which ...
The coat proteins of clathrin-coated vesicles (CCV) spontaneously self-assemble in vitro, but, in vivo, their self-assembly must be regulated. To determine whether phosphorylation might influence coat formation in the cell, the in vivo phosphorylation state of CCV coat proteins was analyzed. Individual components of the CCV coat were isolated by immunoprecipitation from Madin-Darby bovine kidne...
Transcription factor E3 (TFE3) is a transcription factor that binds to E-box motifs and promotes energy metabolism-related genes. We previously reported that TFE3 directly binds to the insulin receptor substrate-2 promoter in the liver, resulting in increased insulin response. However, the role of TFE3 in other tissues remains unclear. In this study, we generated adipose-specific TFE3 transgeni...
We investigated whether Rad51 overexpression plays a role in soft tissue sarcoma (STS) chemoresistance as well as the regulatory mechanisms underlying its expression. The studies reported here show that Rad51 protein is overexpressed in a large panel of human STS specimens. Human STS cell lines showed increased Rad51 protein expression, as was also observed in nude rat STS xenografts. STS cells...
Sterol regulatory element-binding proteins (SREBPs) are a family of membrane-bound transcription factors that regulate cholesterol and fatty acid homeostasis. In mammals, three SREBP isoforms designated SREBP-1a, SREBP-1c, and SREBP-2 have been identified. SREBP-1a and SREBP-1c are derived from the same gene by virtue of alternatively spliced first exons. SREBP-1a has a longer transcriptional a...
The Ethylene Response Factor (ERF) transcription factors form a subfamily of the AP2/ERF family that is instrumental in mediating plant responses to diverse abiotic stressors. Herein, we present isolation and characterization GmERF105 gene from Williams 82 (W82), which rapidly induced by salt, drought, abscisic acid (ABA) treatments soybean. protein contains an AP2 domain localizes nucleus. was...
Systemic deficiency of PIKfyve, the evolutionarily conserved phosphoinositide kinase synthesizing cellular PtdIns5P and PtdIns(3,5)P2 and implicated in insulin signaling, causes early embryonic death in mice. In contrast, mice with muscle-specific Pikfyve disruption have normal lifespan but exhibit early-age whole-body glucose intolerance and muscle insulin resistance, thus establishing the key...
