PluriSIn 1

CAS No. : 91396-88-2

MCE 站：PluriSIn 1

产品活性：PluriSIn 1 (NSC 14613) 是一种酰基-辅酶A去饱和酶 (SCD) 抑制剂，是一种多能细胞特异性的抑制剂。

研究领域：Metabolic Enzyme/Protease  |  Apoptosis

作用靶点：Stearoyl-CoA Desaturase (SCD)  |  Apoptosis

In Vitro: PluriSIn 1, a small-molecule inhibitor of stearoyl-coA desaturase (SCD), on induced pluripotent stem cells (iPS)-derived cardiomyocytes (CM). PluriSIn 1 treatment significantly decreases the mRNA and protein level of Nanog, a marker for both cell pluripotency and tumor progression; importantly, we provide evidence that PluriSIn 1 treatment at 20 ?M for 1 day significantly induces the apoptosis of Nanog-positive iPS derivates (iPSD). In addition, PluriSIn 1 treatment at 20 ?M for 4 days diminished Nanog-positive stem cells in cultured iPSD while not increasing apoptosis of iPS-derived CM. To investigate whether PluriSIn 1 treatment prevents tumorigenicity of iPSD after cell transplantation, we intramyocardially injected PluriSIn 1- or DMSO-treated iPSD in a mouse model of myocardial infarction (MI). DMSO-treated iPSD readily formed Nanog-expressing tumors 2 weeks after injection, which is prevented by treatment with PluriSIn 1. Moreover, treatment with PluriSIn 1 does not change the expression of cTnI, α-MHC, or MLC-2v, markers of cardiac differentiation (P>0.05, n=4). Importantly, PluriSIn 1-treated iPS-derived CM exhibits the ability to engraft and survive in the infarcted myocardium.
