We have previously reported induction of fatty acid synthase ment with 10 nM insulin increased CAT activity by 2.1 + 0.2-, (FAS) gene expression by insulin and adipocyte differentiation in 2.6+ 0.1-, 2.0 + 0.2and 1.7 + 0.2-fold respectively in 3T3-LI 3T3-L1 cells. In order to identify sequences responsible for adipocytes transiently transfected with 2100CAT, -1400CAT, insulin regulation of the ...
Aquaglyceroporins, belonging to the family of aquaporins (AQPs), are integral plasma membrane proteins permeable to water and glycerol that have emerged as key players in obesity. The aim of this study was to investigate the expression profile of AQPs in undifferentiated and differentiated 3T3-L1 cells and to investigate the changes in expression of aquaglyceroporins in 3T3-L1 cells differentia...
An American ginseng (Panax quinquefolius) extract (GE) that contained a quantifiable amount of ginsenosides was investigated for the potential to inhibit proliferation, affect the cell cycle, influence lipid acquisition and adiponectin expression in 3T3-L1 cells. Six fingerprint ginsenosides were quantified by high performance liquid chromatography and the respective molecular weights were conf...
Enhancers are developmentally controlled transcriptional regulatory regions whose activities are modulated through histone modifications or histone variant deposition. In this study, we show by genome-wide mapping that the newly discovered deoxyribonucleic acid (DNA) modification 5-hydroxymethylcytosine (5hmC) is dynamically associated with transcription factor binding to distal regulatory site...
Age-associated thymic involution is characterized by decreased thymopoiesis, adipocyte deposition and changes in the expression of various thymic microenvironmental factors. In this work, we characterized the distribution of fat-storing cells within the aging thymus. We found an increase of unilocular adipocytes, ERTR7(+) and CCR5(+ )fat-storing multilocular cells in the thymic septa and parenc...
Brain and muscle Arnt-like protein-1 (BMAL1; also known as MOP3 or Arnt3) is a transcription factor known to regulate circadian rhythm. Here, we established its involvement in the control of adipogenesis and lipid metabolism activity in mature adipocytes. During adipose differentiation in 3T3-L1 cells, the level of BMAL1 mRNA began to increase 4 days after induction and was highly expressed in ...
The present study including two experiments was designed to determine the effect of media containing different rare earth elements (REE) on proliferation and fatty acids accumulation in 3T3-L1 cell cultures. In Experiment 1, 3T3-L1 preadipocytes in 96-well plates (1.5×10 cells/ml) were cultured with Dulbecco’s modified Eagle’s medium (DMEM) containing 10% fetal bovine serum (FBS) for 24 h. Then...
Insulin-induced differentiation of 3T3 L1 cells to adipocytes can be mimicked by the expression of transfected ras oncogenes but not of the tyrosine-kinase oncogenes src and trk. Expression of two different transfected, dominant inhibitory ras mutants resulted in significant inhibition of insulin-induced differentiation, suggesting that endogenous Ras proteins are mediators of insulin signaling...
The insulin/insulin-like growth factor 1 (IGF-1) signaling pathway is a major regulator of adipose tissue growth and differentiation. We recently demonstrated that human protein tyrosine phosphatase (PTP) L1, a large cytoplasmic phosphatase also known as PTP-BAS/PTPN13/PTP-1E, is a negative regulator of IGF-1R/IRS-1/Akt pathway in breast cancer cells. This triggered us to investigate the potent...
