Endosome maturation requires a coordinated change in the Rab GTPase and phosphoinositide composition of the endosomal membrane. In this issue, Liu et al. (2017. J. Cell Biol. https://doi.org/10.1083/jcb.201705151) identify WDR91 as a ubiquitous Rab7 effector that inhibits phosphatidylinositol 3-kinase activity on endosomes and is critical for endosome maturation, viability, and dendrite growth ...

This study aims to explore the cytotoxic, apoptotic and autophagic effects of thymoquinone on human acute myeloid leukemia. The cytotoxic were determined with 3-(4, 5-dimethylthiazol-2-yl)-2 5-diphenyltetrazolium bromide (MTT) tests. B-cell lymphoma 2 associated X protein (Bax), (Bcl-2), caspase 3, mammalian target rapamycin (mTOR), phosphatidylinositol-3-kinase (PI3K), kinase B (AKT) gene expr...

Objective: To explore the possible mechanism of Erzhi Pill in treatment breast cancer based on network pharmacology. Methods: Through systematic pharmacology database and analysis platform Traditional Chinese medicine (TCMSP) literature review, candidate active ingredients corresponding targets were retrieved collected. The UniProt Human Genome Annotation Database (Genecards) used to compare re...

PTEN/MMAC1 is a tumor suppressor gene located on chromosome 10q23. Inherited PTEN/MMAC1 mutations are associated with a cancer predisposition syndrome known as Cowden's disease. Somatic mutation of PTEN has been found in a number of malignancies, including glioblastoma, melanoma, and carcinoma of the prostate and endometrium. The protein product (PTEN) encodes a dual-specificity protein phospha...

Phosphatidylinositol 3-kinase (PI 3-kinase) is a lipid kinase which has been implicated in mitogenesis, protein trafficking, inhibition of apoptosis, and integrin and actin functions. Here we show using a green fluorescent protein-tagged p85 subunit that phosphatidylinositol 3-kinase is distributed throughout the cytoplasm and is localized to focal adhesion complexes in resting NIH-3T3, A431, a...
