Potent, selective small molecule inhibitors of type III phosphatidylinositol-4-kinase α- but not β-inhibit the phosphatidylinositol signaling cascade and cancer cell proliferation.

چکیده
Two series of inhibitors of type III phosphatidylinositol-4-kinase were identified by high throughput screening and optimised to derive probe compounds that independently and selectively inhibit the α- and the β-isoforms with no significant activity towards related kinases in the pathway. In a cellular environment, inhibition of the α- but not the β-subtype led to a reduction in phosphatidylinositol-4-phosphate and phosphatidylinositol-4,5-bisphosphate concentration, causing inhibition of inositol-1-phosphate formation and inhibition of proliferation in a panel of cancer cell lines.

Phosphatidylinositol 3-kinase (PI3K) inhibitors as cancer therapeutics
Phosphatidylinositol 3-kinases (PI3Ks) are lipid kinases that regulate diverse cellular processes including proliferation, adhesion, survival, and motility. Dysregulated PI3K pathway signaling occurs in one-third of human tumors. Aberrantly activated PI3K signaling also confers sensitivity and resistance to conventional therapies. PI3K has been recognized as an attractive molecular target for n...
متن کاملInhibition of mitogen-activated protein kinase and phosphatidylinositol 3-kinase activity in MCF-7 cells prevents estrogen-induced mitogenesis.
Estrogen acts to promote DNA synthesis in the MCF-7 human breast cancer cell line via its interaction with high levels of estrogen receptor. The primary mode of estrogen action has been considered to be through transcriptional activation of genes containing estrogen response elements, including the immediate early genes c-myc and fos. Recent reports have indicated that estrogen, acting through ...
متن کاملTwo hits are better than one: targeting both phosphatidylinositol 3-kinase and mammalian target of rapamycin as a therapeutic strategy for acute leukemia treatment
Phosphatidylinositol 3-kinase (PI3K) and mammalian target of rapamycin (mTOR) are two key components of the PI3K/Akt/mTOR signaling pathway. This signal transduction cascade regulates a wide range of physiological cell processes, that include differentiation, proliferation, apoptosis, autophagy, metabolism, motility, and exocytosis. However, constitutively active PI3K/Akt/mTOR signaling charact...

Background: Novel roles for the interaction of cardiotonic steroids to Na+/K+-ATPase have been established in recent years. The aim of the present study was to investigate the intracellular signaling events downstream the action of ouabain on Na+/K+-ATPase in Sertoli cell obtained from immature rats. Treatment of Sertoli cells with ouabain (1 μM) induced a rapid and transient increase in the ex...
متن کاملThe Role of Wnt/β-catenin Signaling Pathway in Rat Primordial Germ Cells Reprogramming and Induction into Pluripotent State
Primordial Germ Cells (PGCs) are unipotent precursors of the gametes. PGCs can give rise to a type of pluripotent stem cells in vitro that are called embryonic germ (EG) cells. PGCs can also acquire such pluripotency in vivo and generate teratomas. Under specific culture conditions, PGCs can be reprogrammed to embryonic germ cells which are capable of expression of key pluripotency marker...
