چکیده

Using a subtraction method, we have isolated genes that are induced early in the differentiation of mouse 3T3-L1 preadipocyte cells into adipocytes. These include the genes encoding transcription factors and signalling proteins, as well as unknown genes. Bach1, a transcription factor, and ARA70, a cofactor, were rapidly induced during differentiation. The induction of these two genes was observed only in growth-arrested 3T3-L1 cells, and not in proliferating cells. In NIH-3T3 cells, no induction was observed under either set of conditions. These results strongly indicate that Bach1 and ARA70 have valuable roles at the onset of adipocyte differentiation.

Regulation of adipocyte differentiation of 3T3-L1 cells by PDZRN3.

PDZRN3, a member of the PDZRN (or LNX) family of proteins, is essential for the differentiation of mesenchymal stem cells into myotubes, but it plays an inhibitory role in the differentiation of these cells into osteoblasts. Given that mesenchymal stem cells also differentiate into adipocytes, we examined the possible role of PDZRN3 in adipogenesis in mouse 3T3-L1 preadipocytes. The expression ...

Gelsolin, an actin regulatory protein, is required for differentiation of mouse 3T3-L1 cells into adipocytes.

To elucidate molecular mechanisms of adipocyte differentiation, we previously isolated TC10-like/ TC10betaLong (TCL/TC10betaL), which was transiently expressed in the early phase of adipogenesis of 3T3-L1 cells and seemed to be a positive regulator of adipogenesis. By using TCL/TC10betaL-overexpressing NIH-3T3 cells, we also isolated gelsolin as a gene whose expression was up-regulated by TCL/T...

Fifty Percent Ethanolic Extract of Momordica charantia Inhibits Adipogenesis and Promotes Adipolysis in 3T3-L1 Pre-Adipocyte Cells

Background: Natural products have gained importance recently for the treatment of obesity and its complications, partly because of the side effects of modern drugs.Hence, we aimed to study and compare the effect of varying concentrations of Momordicacharantiaon adipogenesis and adipolysis using 3T3-L1 pre-adipocyte cell lines. Methods: 3T3-L1 pre-adipocytes were procured from the National Ce...

A Novel Splicing Variant of Peroxisome Proliferator-Activated Receptor-γ (Pparγ1sv) Cooperatively Regulates Adipocyte Differentiation with Pparγ2

Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors that regulate expression of a number of genes associated with the cellular differentiation and development. Here, we show the abundant and ubiquitous expression of a newly identified splicing variant of mouse Pparγ (Pparγ1sv) that encodes PPARγ1 protein, and its importance in adipogenesis. The novel splicing variant has a...
