An indole alkaloid tumor promoter, dihydroteleocidin B, was able to modulate a membrane property of 3T3-L1 preadipocytes, showing an almost complete reduction of epidermal growth factor binding capacity. This receptor modulating potency of dihydroteleocidin B, was 10 times that of a phorbol ester tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA). Dihydroteleocidin B, however, had little...

A standardized extract of the plant Caralluma fimbriata (SlimalumaTM) is widely used in the management of obesity but its mode of action is not yet clarified. This study investigated the ability of Caralluma fimbriata extract (CFE) to modify pre-adipocyte cell division and thus the development of hyper-plastic obesity. Mouse 3T3-L1 pre-adipocyte cell line samples were treated with different con...

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 cente...

BACKGROUND A major portion of available fatty acids for adipocyte uptake is derived from lipoprotein lipase (LPL)-mediated hydrolysis of circulating lipoprotein particles. In vivo studies aimed at identifying the precise role of adipocyte-derived LPL in fat storage function of adipose tissue have been unable to provide conclusive evidence due to compensatory mechanisms that activate endogenous ...

The adipocyte-derived hormone leptin is a critical regulator of many physiological functions, ranging from satiety to immunity. Surprisingly, very little is known about the transcriptional pathways that regulate adipocyte-specific expression of leptin. In a recent published study, we pursued a strategy integrating BAC transgenic reporter mice, in vitro reporter assays, and chromatin state mappi...

Abstract Background To investigate the relationship between levels of serum adipokine retinol-binding protein 4 (RBP4) and essential hypertension as well to explore role mechanism RBP4-induced activation renin–angiotensin system (RAS) in adipocyte. Methods From December 2016 March 2019, 96 hypertensive patients without treatment 64 healthy nonhypertensive subjects were recruited. The difference...

Environmental endocrine disruptors (EDCs), including bisphenol-A (BPA), have been recently involved in obesity and diabetes by dysregulating adipose tissue function. Our aim was to examine whether prolonged exposure to low doses of BPA could affect adipogenesis and adipocyte metabolic functions. Therefore, 3T3-L1 pre-adipocytes were cultured for three weeks with BPA 1 nM to mimic human environm...

The transcription factor PPARγ is the key regulator of adipocyte differentiation, function and maintenance, and the cellular target of the insulin-sensitizing thiazolidinediones. Identification and functional characterization of genes regulated by PPARγ will therefore lead to a better understanding of adipocyte biology and may also contribute to the development of new anti-diabetic drugs. Here,...

To elucidate the role of norepinephrine (NE) in the hyperplasia of brown adipose tissue (BAT), we investigated the effects of NE on the expression of fibroblast growth factor-2 (FGF-2) in rat brown adipocyte primary culture and on capillary growth in an in vitro angiogenesis model in which microvascular fragments and brown adipocyte precursor cells isolated from rat BAT were grown in coculture....
