Characterization of VPS34-IN1, a selective inhibitor of Vps34, reveals that the phosphatidylinositol 3-phosphate-binding SGK3 protein kinase is a downstream target of class III phosphoinositide 3-kinase [PDF]

, 2014
The Vps34 (vacuolar protein sorting 34) class III PI3K (phosphoinositide 3-kinase) phosphorylates PtdIns (phosphatidylinositol) at endosomal membranes to generate PtdIns(3)P that regulates membrane trafficking processes via its ability to recruit a ...

High‐Content SRS Imaging Unveils Altered Cholesterol Metabolism in Ovarian Cancers Under CAR‐T Treatment

Advanced Science, EarlyView.
High‐content Stimulated Raman Scattering (SRS) Imaging reveals that ovarian cancer cells surviving Chimeric Antigen Receptor (CAR) ‐T cell challenge exhibit increased cholesterol esterification. Pharmacological inhibition of this pathway with Avasimibe significantly enhances CAR‐T induced killing of ovarian cancer cells by reducing cancer cell ...

Phosphatidylinositol 3 Kinase δ Inhibitors

The Cancer Journal, 2019
Abstract Inhibitors of PI3Kδ hold great potential for the therapy of chronic lymphocytic leukemia and B-cell malignancies. After initially exciting efficacy results with idelalisib, the first-in-class inhibitor, the emergence of unexpected and unpredictable autoimmune toxicities, worse in less heavily treated and younger patients, has ...

Chaperone‐Mediated Autophagic Degradation of USP9X in Macrophages Exacerbates Postmyocardial Infarction Inflammation and Cardiac Dysfunction

Advanced Science, EarlyView.
This study demonstrates that inflammatory stimuli induce the acetylation‐triggered, chaperone‐mediated autophagic degradation of ubiquitin‐specific peptidase 9 X‐linked (USP9X) in macrophages. USP9X acts as a macrophage “inflammation switch” after myocardial infarction (MI). USP9X loss destabilizes tumor necrosis factor receptor‐associated factor (TRAF)

Atypical protein kinase C (PKCzeta/lambda) is a convergent downstream target of the insulin-stimulated phosphatidylinositol 3-kinase and TC10 signaling pathways. [PDF]

, 2004
Insulin stimulation of adipocytes resulted in the recruitment of atypical PKC (PKCzeta/lambda) to plasma membrane lipid raft microdomains. This redistribution of PKCzeta/lambda was prevented by Clostridium difficile toxin B and by cholesterol depletion ...

Rapamycin induces transactivation of the EGFR and increases cell survival. [PDF]

, 2009
The mammalian target of rapamycin (mTOR) signaling network regulates cell growth, proliferation and cell survival. Deregulated activation of this pathway is a common event in diverse human diseases such as cancers, cardiac hypertrophy, vascular ...

Integrative Approaches to Treating Cellular Senescence in Kidney Disease

Advanced Science, EarlyView.
ABSTRACT Cellular senescence in the kidney plays a crucial role in the progression of acute kidney injury and chronic kidney disease. Therapeutic approaches targeting senescent cells, such as small molecule senolytic and senomorphic drugs, display efficacy in preclinical models.

Phosphatidylinositol 3‐kinase regulation of fluid phase endocytosis

FEBS Letters, 1995
Endocytosis of the fluid phase marker, horse radish peroxidase, into baby hamster kidney cells is inhibited by treatment of cells with the fungal metabolite wortmannin. The IC50 of approximately 5 nM is consistent with the well‐described action of wortmannin upon phosphatidylinositol (PI) 3‐kinase. Analysis of the kinetics of uptake indicates a > 50%

CircRSU1 Activates the hnRNPA1/HIF‐1α/CD24 Signaling Axis, Promoting Stemness Features of Hepatocellular Carcinoma

Advanced Science, EarlyView.
This study reveals circRSU1 with important oncogenic roles in hepatocellular carcinoma (HCC). CircRSU1, highly abundant in HCC, interacts with and stabilizes hnRNPA1 from ubiquitination and degradation. This stabilization facilitates hnRNPA1 binding to the internal ribosome entry site of HIF1A to increase HIF‐1α protein translation.
