Our data show that combined targeting of MEK and PI3K-AKT with mTOR is a better option than single agents alone for KRAS mutant NSCLC, thus opening the possibility of a beneficial treatment strategy in the future.
Silencing long non-coding RNA ROR improves sensitivity of non-small-cell lung cancer to cisplatin resistance by inhibiting PI3K/Akt/mTOR signaling pathway.
Although the role of EGFR in PI3K/Akt signaling cascade in NSCLC is extensively studied, the molecular link between EGFR and p53 and the role of ROS in pathogenesis of NSCLC are limitedly addressed.
Here we investigated PIK3CA gene alterations, the expression of core components of PI3K pathway, and evaluated their clinical importance in non-small cell lung cancer (NSCLC).
Taken together, our study provides evidence that PDCD4 inhibits cell growth through PI3K/Akt signaling in NSCLC and may be a potential therapeutic target for NSCLC.
Shikonin is a naphthoquinone compound isolated from the roots of <i>Lithospermum erythrorhizon</i> In the present study, the anti-cancer activity of Shikonin was evaluated on afatinib-resistant NSCLC <i>in vitro</i> and <i>in vivo</i> The data showed that Shikonin inhibited the proliferation and induced apoptosis of afatinib-resistant NSCLC cell line by activating apoptosis signaling pathway and negatively regulating PI3K/Akt signaling pathway.
These data suggest that cardamonin suppressed NSCLC cell proliferation and inhibited metastasis partly by restraining the PI3K/Akt/mTOR pathway and it might be an effective therapeutic compound for NSCLC in the future.
SPIN1 overexpression in miR-409-transfected NSCLC cells effectively rescued the suppression of cell migration, growth, and proliferation regulated by miR-409. miR-409 regulates the PI3K/AKT (protein kinase B) pathway in NSCLC.
We hypothesized that insulin-like growth factor-binding protein-3 might be targeted by microRNA-125b and promote tumor invasion and poor outcome in non-small-cell lung cancer via activation of the PI3K/AKT signaling pathway.
Mechanistically, luteolin induced degradation of the EGF receptor by inhibiting the association of Hsp90 with the mutant EGF receptor, and, therefore, prevented PI3K/Akt/mTOR signalling, which resulted in NSCLC cell apoptosis.
NSCLC cell lines with mutant KRas-Gly12Asp had activated phosphatidylinositol 3-kinase (PI-3-K) and mitogen-activated protein/extracellular signal-regulated kinase kinase (MEK) signaling, whereas those with mutant KRas-Gly12Cys or mutant KRas-Gly12Val had activated Ral signaling and decreased growth factor-dependent Akt activation.
The protein expression of Bax, epidermal growth factor receptor (EGFR), phosphatidylinositol 3‑kinase (PI3K) and phosphorylated‑protein kinase B (AKT) was examined by western blot analysis. miR‑145 expression was downregulated in patients with NSCLC who were treated with chemotherapy.
Our findings that both EML4-ALK and mutant EGFR upregulate PD-L1 by activating PI3K-AKT and MEK-ERK signaling pathways in NSCLC reveal a direct link between oncogenic drivers and PD-L1 expression.
In the present study, the effects of curcumin‑induced multiple PCDs on human non‑small cell lung cancer (NSCLC) cells and the potential molecular mechanisms of apoptosis and autophagy triggered by curcumin via the PI3K/Akt/mTOR signaling pathway were explored, further confirmed by co‑culture of curcumin with mTOR blocker rapamycin and PI3K/Akt inhibitor LY294002.
The upregulation of miR-126 in NSCLC A549 cells can reduce the expression of the target gene PIK3R2 and influence the PTEN/PI3K/AKT signaling pathway, suppressing the proliferation, migration, and invasive abilities of A549 cells.
Nicotine, the major component among the 4000 identified chemicals in cigarette smoke, binds to nicotinic acetylcholine receptors (nAChRs) on non-small-cell lung cancer (NSCLC) cells and regulates cellular proliferation by activating mitogen-activated protein kinases [AQ: MAPK has been expanded to mitogen-activated protein kinases.Please approve.]and PI3K/Akt pathways.
The mechanisms underlying acquired resistance to TKIs have been explored and Phosphoinositide 3- kinase (PI3K)/Akt/mTOR pathway plays a very important role in NSCLC development as well as EGFR-TKI resistance.
