In summary, our findings showed that EHMT2 facilitated EGFR-TKI resistance by regulating the PTEN/AKT pathway in NSCLC cells, suggesting that EHMT2 may be a target in the clinical treatment of EGFR-TKI-resistant NSCLC.
In summary, our results support the role of ERK, AKT and TAK1 in mediating the expression of PD‑L1 during the EMT process, and indicate a promising strategy of PD‑L1‑targeted therapy for the clinical treatment of NSCLC.
In the present study, we investigated the effect of Akt1 on homologous recombination (HR)-dependent repair of radiation-induced DSBs in non-small cell lung cancer (NSCLC) cells A549 and H460.
In this review, we will briefly discuss the main PTEN/PI3K/AKT pathway alterations found in NSCLC, as well as the cell processes regulated by PTEN/PI3K/AKT leading to tumorigenesis.
In this study, we showed that erlotinib (1.25-10μM) treatment down-regulating of TS expression in an AKT inactivation manner in two NSCLC cell lines, human lung squamous cell carcinoma H1703 and adenocarcinoma H1975 cells.
In this study, we showed that salinomycin (0.5-2μg/mL) treatment down-regulating of TS expression in an AKT inactivation manner in two NSCLC cell lines, human lung adenocarcinoma A549 and squamous cell carcinoma H1703 cells.
Inhibition of FASN was accompanied by a loss in AKT activation and profound apoptosis in several non-small cell lung cancer (NSCLC) cells at the growth inhibitory concentrations of EC1 and EC5.
Inhibition of TAZ by panobinostat or short hairpin RNA sensitized KRAS-mutant/EGFR-wild-type NSCLC to gefitinib through abrogating AKT/mammalian target of rapamycin (mTOR) signaling.
Interestingly, miR-196a was significantly overexpressed also in human NSCLC-derived cell lines (n=11) and primary lung cancer samples (n=28).By manipulating the expression of miR-196a in BEAS-2B and NCI-H460 cells, we obtained compelling evidence that this miRNA acts downstream the PI3K/AKT pathway, mediating some of the proliferative, pro-migratory and tumorigenic activity that this pathway exerts in lung epithelial cells, possibly through the regulation of FoxO1, CDKN1B (hereafter p27) and HOXA9.
Long non-coding RNA UCA1 induces non-T790M acquired resistance to EGFR-TKIs by activating the AKT/mTOR pathway in EGFR-mutant non-small cell lung cancer.
Luteoloside induces G<sub>0</sub>/G<sub>1</sub> arrest and pro-death autophagy through the ROS-mediated AKT/mTOR/p70S6K signalling pathway in human non-small cell lung cancer cell lines.
Mechanistically, we found that circFGFR3 promoted NSCLC cell invasion and proliferation via competitively combining with miR-22-3p to facilitate the galectin-1 (Gal-1), p-AKT, and p-ERK1/2 expressions.
Moreover, miR-182 could repress cell migration, invasion, and EMT of lung cancer cells induced by hepatocyte growth factor (HGF). miR-182 might suppress the EMT and metastasis via inactivation of Met/AKT/Snail in non-small cell lung cancer (NSCLC) cells, which implicates miR-182 may be useful as a new therapeutic target in NSCLC.
Moreover, mRNA expression of selected DEGs (SGK1, IGFBP3, PEG10, GDF15, PTGES, S100P, respectively) correlated with the activation status of the PI3K/AKT pathway assessed by S473 phosphorylation in NSCLC cell lines (n = 6).
Mutations of EGFR, ERBB2, ERBB3, ERBB4, KRAS, NRAS, BRAF, PTEN, PIK3CA, LKB1, and AKT1 genes were determined by direct sequencing in 173 surgically resected NSCLCs--56 squamous cell carcinomas (SCCs) and 117 adenocarcinomas (ACs).
Netrin‑1 interference potentiates epithelial‑to‑mesenchymal transition through the PI3K/AKT pathway under the hypoxic microenvironment conditions of non‑small cell lung cancer.
Next, we discovered that LMO1 promoted cancer cell proliferation in our in vitro/vivo cell proliferation assay, and our cell signaling experiments showed that LMO1 expression correlated with elevated AKT phosphorylation in NSCLC, while the AKT phosphorylation was required for LMO1's oncogenic effects.
