- |||||||||| Journal: ENKUR Is Involved in the Regulation of Cellular Biology in Colorectal Cancer Cells via PI3K/Akt Signaling Pathway. (Pubmed Central) - May 14, 2019
Downregulation of the epithelial marker, E-cadherin, and upregulation of the mesenchymal markers, vimentin and N-cadherin, were detected in ENKUR-underexpressing cells, suggesting the induction of epithelial-mesenchymal transition. In conclusion, the present study demonstrates that ENKUR may be responsible for alterations in the proliferative, migratory, and invasive potential of colorectal cancer cells through possible involvement in the phosphoinositide 3-kinase /Akt signaling pathway.

Journal: MicroRNA-150 enhances radiosensitivity by inhibiting the AKT pathway in NK/T cell lymphoma. (Pubmed Central) - May 11, 2019 Conclusively, EP inhibits the active secretion of HMGB1 from proximal tubular cells during IR injury by inducing HO-1 via activation of PI3K/Akt and Nrf2 pathway. Taken together, this study demonstrates that miR-150 might serve as a potential therapeutic sensitizer through inhibition of the AKT pathway in NK/T cell lymphoma treatment.

Journal: Exosomal microRNA-32-5p induces multidrug resistance in hepatocellular carcinoma via the PI3K/Akt pathway. (Pubmed Central) - May 11, 2019 Our findings suggest that inhibition of 14, 15-EET or inactivation of integrin αvβ3/FAK/PI3K/AKT pathway could serve as a novel approach to reverse EMT and cisplatin resistance in breast cancer cells. Our study demonstrated that the multidrug-resistant cell, Bel/5-FU delivers miR-32-5p to sensitive cell, Bel7402 by exosomes and activates the PI3K/Akt pathway to further induce multidrug resistance by modulating angiogenesis and EMT.

Further analyses demonstrated that COS induced the phosphorylation of extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), p38, p85 and Akt, and the nuclear translocation of p65, indicating that they are able to activate the mitogen-activated protein kinases (MAPKs) and phosphoinositide 3-kinases (PI3K)/Akt signaling pathways dependent on nuclear factor (NF)-κB activation. In conclusion, COS activate RAW 264.7 cells via the MAPK and PI3K/Akt signaling pathways and are potential novel immune potentiators.

Moreover, γδT17-dependent skin inflammation was ameliorated in mice deficient in RhoH, an adaptor known to recruit Syk. Thus, we deciphered lineage-specific TCR signaling and identified the Syk/PI3K pathway as a critical determinant of proinflammatory γδT cell differentiation.

Clinical, Journal: Kinome rewiring reveals AURKA limits PI3K-pathway inhibitor efficacy in breast cancer. (Pubmed Central) - May 8, 2019 Incomplete inhibition of AURKA was a common source of therapy failure, and combinations of PI3K, AKT or mTOR inhibitors with the AURKA inhibitor MLN8237 were highly synergistic and durably suppressed mTOR signaling, resulting in apoptosis and tumor regression in vivo. This signaling map identifies survival factors whose presence limits the efficacy of targeted therapies and reveals new drug combinations that may unlock the full potential of PI3K-AKT-mTOR pathway inhibitors in breast cancer.

Journal: Morin inhibits PDGF-induced proliferation, migration, and invasion of vascular smooth muscle cells via modulating p27KIP1, AKT, and MMP-9 activities. (Pubmed Central) - May 8, 2019 ...Using the PI3K inhibitor, LY294002, we revealed that AKT is a key regulator in the inhibitory mechanism of morin against PDGF-induced proliferation of VSMCs...Using electrophoretic mobility shift assays, we verified that NF-κB, AP-1, and Sp-1 transcription factors are implicated in the mode of action of morin, which suppresses the MMP-9 activity in PDGF-induced VSMCs. Based on the results, we believe that morin may be a potential therapeutic agent for atherosclerosis without negative side effect.

Journal: Talaumidin Promotes Neurite Outgrowth of Staurosporine-Differentiated RGC-5 Cells Through PI3K/Akt-Dependent Pathways. (Pubmed Central) - May 7, 2019 The neurite outgrowth effect of talaumidin was inhibited by phosphatidylinositol 3-kinase (PI3K) inhibitor, LY294002, but not by Erk inhibitor, PD98059. These data suggest that talaumidin promotes neurite outgrowth through PI3K/Akt pathway and that the potential of talaumidin serves as a promising lead compound for the treatment of retinal degenerative disorders.
