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.
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.
In conclusion, this integrative pharmacology-based analysis revealed the anti-NPC effects of RO might be related to its regulatory impact via the PI3K-AKT signaling pathway, the Wnt signaling pathway, and the cAMP signaling pathway by targeting VEGFA, TP53, and HSPA8.
Moreover, we explored whether HAGLROS modulated the expression of autophagy-related gene 14 (ATG14) by competitively sponging miR-100, and then regulated the briskness of PI3K/AKT/mTOR signals in NPC development.
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.
Pre-treatment with angiotensin-(1-7) inhibits tumor growth via autophagy by downregulating PI3K/Akt/mTOR signaling in human nasopharyngeal carcinoma xenografts.
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.
The expression of Klf4 in the nucleus can be used as a biomarker for predicting the effects of cetuximab treatment in nasopharyngeal carcinoma, which might be attributed to the H-RAS and PI3K mutations, leading to cetuximab resistance.
Taken together, our results not only provide understanding of the molecular mechanisms by which PI3K/AKT signaling is activated but also suggest that targeting the LZTS2/PI3K/AKT signaling axis is a promising therapeutic strategy for radiosensitization of nasopharyngeal carcinoma.
Downregulation of monocarboxylate transporter 1 inhibits the invasion and migration through suppression of the PI3K/Akt signaling pathway in human nasopharyngeal carcinoma cells.
In conclusion, these results indicate that camptothecin treatment may inhibit the viability of NPC cells and aggressiveness by regulating the TGF-β-induced PI3K/AKT signaling pathways, which in turn may be a potential molecular target for the treatment of NPC.
