miR-144-3p was significantly overexpressed, whereas PTEN was more underexpressed in tumor tissues than in adjacent tissues. miR-144-3p promoted the proliferation and invasion of NPC cells and inhibited apoptosis by directly targeting PTEN, which improves PI3K-Akt signaling. miR-144-3p forced epithelial-mesenchymal transition in NPC.
Taken together, BMI-1 depletion enhanced the chemosensitivity of NPC cells by inducing apoptosis; which is associated with inhibition of the PI3K/AKT pathway.
Traditional Herbal Formula NPC01 Exerts Antiangiogenic Effects through Inhibiting the PI3K/Akt/mTOR Signaling Pathway in Nasopharyngeal Carcinoma Cells.
In conclusion, TCS radiosensitized NPC <i>in vitro</i> and <i>in vivo</i> via downregulation of PI3K pathways and the upregulation of cleaved caspase-3.
These findings show that mutated PI3K may be involved in the NPC tumorigenesis but does not affect patient's prognosis, suggesting that PI3K is a potential target in NPC for targeted therapeutics using specific kinase inhibitors.
Profiling of somatic mutations and copy number variations (CNV) in NPC tumors identified alterations in RTK/RAS/PI3K, NOTCH, DNA repair, chromatin remodeling, cell cycle, NF-κB, and TGF-β pathways.
VPS33B interacts with NESG1 to modulate EGFR/PI3K/AKT/c-Myc/P53/miR-133a-3p signaling and induce 5-fluorouracil sensitivity in nasopharyngeal carcinoma.
Taken together, our data suggest that APLNR could potentially predict prognosis for patients with NPC and inhibit proliferation, migration, invasion, and EMT in nasopharyngeal cancer cells.-Liu, Y., Liu, Q., Chen, S., Liu, Y., Huang, Y., Chen, P., Li, X., Gao, G., Xu, K., Fan, S., Zeng, Z., Xiong, W., Tan, M., Li, G., Zhang, W. APLNR is involved in ATRA-induced growth inhibition of nasopharyngeal carcinoma and may suppress EMT through PI3K-Akt-mTOR signaling.
Pre-treatment with angiotensin-(1-7) inhibits tumor growth via autophagy by downregulating PI3K/Akt/mTOR signaling in human nasopharyngeal carcinoma xenografts.
Genetic variations in the PI3K-PTEN-AKT-mTOR pathway are associated with distant metastasis in nasopharyngeal carcinoma patients treated with intensity-modulated radiation therapy.
To investigate the effects of microRNA-122 (miR-122) on the proliferation and apoptosis of nasopharyngeal carcinoma (NPC) HONE-1 cells, and its correlation with the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway.
Galangin effects on apoptosis and S-phase arrest in NPC cells are mediated via interfering with the PI3K-AKT signaling pathway in a p53-independent manner.
