Application

LY2109761 has been used as an inhibitor of type I and II transforming growth factor-beta (TGFβ) receptors to reduce the phosphorylation of SMAD2 (mothers against decapentaplegic homolog) in HepG2 cells.

Biochem/physiol Actions

LY2109761 is a potent and orally active TGF-β receptor (TGFβR) type I & II dual inhibitor (IC50 = 70 and 322 nM against TGFβRI/ALK5 and TGFβRII autophosphorylation, respectively, with 4 μM ATP), inhibiting Fyn/JNK3/Lck/MKK6/SAPK2α only at much higher concentrations (58-89% inhibition at 20 μM) and exhibiting little or no potency against 37 other kinases (IC50 >20 μM). LY2109761 inhibits 0.25 ng/mL TGFβ-induced NIH/3T3 proliferation in cultures (IC50 = 210 nM; 2-hr pretreatment prior to TGFβ for 24 hrs) and suppresses human MX1 breast carcinoma xenograft tumor growth in mice in vivo (by ∼80% on day 37; 75 mg/kg p.o. bid from day 7 to 20). When administered in combination with gemcitabine (25 mg/kg/day i.p.), LY2109761 (50 mg/kg p.o. bid) is shown to significantly reduce tumor burden and spontaneous abdominal metastases in a murine model of metastatic pancreatic cancer.
LY2109761 suppresses transforming growth factor (TGF)-β1-induced fibroblasts proliferation and collagen synthesis in hypertrophic scar fibroblasts. Therefore, it is used in treating hypertrophic scars.

Previous studies have shown that CD61 (integrin-β3) promotes the differentiation of human umbilical cord mesenchymal stem cells (hUC-MSCs) into germ-like cells. However, the mechanism remains unclear. In this study, we showed that overexpression of CD61 in canine adipose-derived mesenchymal stem

Expression of the Coxsackie and Adenovirus Receptor (CAR) is frequently reduced in carcinomas, resulting in decreased susceptibility of such tumors to infection with therapeutic adenoviruses. Because CAR participates physiologically in the formation of tight-junction protein complexes, we examined whether molecular

The stem cell niche is a complex local signaling microenvironment that sustains stem cell activity during organ maintenance and regeneration. The mammary gland niche must support its associated stem cells while also responding to systemic hormonal regulation that triggers pubertal

Most pancreatic cancer patients present with inoperable disease or develop metastases after surgery. Conventional therapies are usually ineffective in treating metastatic disease. It is evident that novel therapies remain to be developed. Transforming growth factor beta (TGF-beta) plays a key

JPJD was an ideal alternative traditional Chinese medicine compound in the prevention and treatment of CRC, but its underlying mechanisms has not been fully elucidated. In this study, we demonstrated in vitro that TGF-β-induced EMT promoted the invasion and metastasis
