Endotrophin (Mus musculus)
Endotrophin (Mus musculus) is an adipokine, a cleavage fragment derived from Collagen VI, whose levels are elevated in adipose tissue and breast tumors of obese mice. Endotrophin (Mus musculus) activates the TGF-β signaling pathway and reduces the expression of hormone-sensitive lipase. Endotrophin (Mus musculus) induces adipogenesis, lipid accumulation, fibrosis, inflammation, angiogenesis, adipose tissue expansion, epithelial-mesenchymal transition, and insulin resistance; it also induces Cisplatin (HY-17394) resistance in cancer cells. Endotrophin (Mus musculus) can be used in research related to metabolic diseases such as obesity and type 2 diabetes, as well as cancers such as breast cancer.

Biological Activity
Endotrophin (Mus musculus) (24 h) upregulates the expression of pro-fibrotic (Col1α1, Tgfβ1, TgfβR2) and pro-inflammatory (Nlrp3, Tlr4) genes in the stromal vascular fraction (SVF) isolated from mouse white adipose tissue (WAT)[1].
Endotrophin (Mus musculus) (24-72 h) induces fibrosis in differentiating 3T3-L1 mouse adipocytes, reduces adiponectin expression, promotes adipogenesis, inhibits lipolysis, and increases lipid accumulation[1].
Endotrophin (Mus musculus) (24 h) upregulates the expression of Lox, pro-inflammatory genes (Il-1β, Tnf-α, F4/80), and M1 macrophage markers (Cd40, Cd86) in primary macrophages isolated from mouse white adipose tissue (WAT)[1].
Endotrophin (Mus musculus) is abundantly secreted in fully differentiated 3T3-L1 adipocytes, whereas no secreted level is detected in 3T3-L1 preadipocytes[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Neutralizing antibody against Endotrophin (Mus musculus) neutralizes endotrophin activity in high-fat diet-induced obese mice and significantly improves insulin sensitivity[2].
Overexpression of Endotrophin (Mus musculus) in MMTV-PyMT transgenic mice significantly increases primary tumor volume, promotes the growth of lung metastatic lesions, and restores tumor growth in collagen VI-deficient MMTV-PyMT mice[2].
Induction of Endotrophin (Mus musculus) confers cisplatin resistance in breast tumor-bearing mice, while neutralizing Endotrophin activity or reducing its levels using TZDs restores cisplatin sensitivity[2].
Endotrophin (Mus musculus) induces adipose tissue fibrosis and inflammation in mice, and causes systemic dyslipidemia, hepatic steatosis and insulin resistance; blocking endogenous Endotrophin with neutralizing antibodies effectively reverses these manifestations[3].
