Protein kinase Cα mediates erlotinib resistance in lung cancer cells.
Overexpression and mutational activation of the epidermal growth factor receptor (EGFR) plays an important role in the pathogenesis of non-small cell lung cancer (NSCLC). EGFR tyrosine-kinase inhibitors (TKIs) are given as a primary therapy for advanced patients with EGFR-activating mutations; however, the majority of these tumors relapse and patients eventually develop resistance to TKIs. To a...
متن کاملMigration of retinal pigment epithelium cells is regulated by protein kinase Cα in vitro.
PURPOSE Retinal pigment epithelium (RPE) cell migration and proliferation are considered key elements in proliferative vitreoretinopathy (PVR). Downregulation of protein kinase Cα (PKCα) can inhibit RPE cell proliferation. Here, we sought to analyze whether PKCα affects the migration of RPE cells. METHODS Human RPE (hRPE) cells were cultured, confirmed by immunofluorescence staining, and divi...
متن کاملProtein Kinase Cα Modulates Estrogen-Receptor-Dependent Transcription and Proliferation in Endometrial Cancer Cells
Endometrial cancer is the most common invasive gynecologic malignancy in developed countries. The most prevalent endometrioid tumors are linked to excessive estrogen exposure and hyperplasia. However, molecular mechanisms and signaling pathways underlying their etiology and pathophysiology remain poorly understood. We have shown that protein kinase C α (PKC α ) is aberrantly expressed in endome...
متن کاملTargeting of Protein Kinase Cα to Caveolae
Previously, we showed caveolae contain a population of protein kinase Calpha (PKCalpha) that appears to regulate membrane invagination. We now report that multiple PKC isoenzymes are enriched in caveolae of unstimulated fibroblasts. To understand the mechanism of PKC targeting, we prepared caveolae lacking PKCalpha and measured the interaction of recombinant PKCalpha with these membranes. PKCal...
متن کاملExpression of Anaplastic Lymphoma Kinase Protein in Human Breast Cancer
Background & Objectives: Anaplastic lymphoma Kinase (ALK) is a receptor tyrosine kinase involved in the genesis of several human cancers. ALK was initially identified because of its involvement in anaplastic large cell lymphoma (ALCL). ALK is believed to foster tumorigenesis following activation by autocrine and/or paracrine growth loops. Studies reveal that the presence of anti-ALK antibodies ...
