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.
However, there is a lack of information about the ability of PolyI:C to affect PI3K/Akt/p53 signaling pathway in non-small cell lung cancer (NSCLC), and its pharmacodynamic evaluation in vivo still remain unclear so far.
Further analyses identified an integrin β3-mediated ternary complex comprising NRP1-integrin β3-KRAS<sup>MUT</sup> and its downstream signaling of PI3K-Akt and RalB-TBK1 as a primary resistance mechanism of KRAS<sup>MUT</sup> NSCLC to cetuximab treatment.
HYSA suppressed LPS-mediated proliferation, migration, invasion, and EMT in A549 and H1299 cells by inhibiting the PI3K/Akt/mTOR and ERK/MAPK signaling pathways, indicating that HYSA may be a potential candidate to treat inflammation-mediated NSCLC.
The present findings suggested that treatment with pemetrexed may exhibit synergistic effects with PTEN on lung cancer cells via the inhibition of the PI3K/AKT/mTOR signaling pathway and through carbohydrate metabolism, and treatment with pemetrexed combined with PTEN overexpression may represent a novel therapeutic strategy for the treatment of NSCLC.
The present study investigated the effects of a PI3K inhibitor on NSCLC growth in bone and osteoclast formation, and aimed to determine whether it could control symptoms associated with bone metastasis.
Mechanistically, miR-31 directly repressed RASA1 and FIH-1 expression, and thus, at least partially activated the RAF-MEK-ERK and PI3K-AKT signaling pathways in NSCLC with acquired resistance to gefitinib.
We report for the first time significant differences in dynamic signaling between colorectal cancer and NSCLC cell lines exposed to clinically relevant equimolar concentrations of the pan-PI3K inhibitor pictilisib including a lack of reduction of p-AKTser473 in colorectal cancer cell lines (<i>P</i> = 0.037) and lack of compensatory increase in p-MEK in NSCLC cell lines (<i>P</i> = 0.036).
<b>Conclusion:</b> Taken together, we proved that miR-224 might play essential roles in cellular functions of nutrient-depleted A549 cells possibly through regulating the target PTEN and downstream signal PI3K, suggesting the potential of miR-224 to be a therapeutic target for NSCLC therapy.
Our results suggest that miR-503 inhibits NSCLC progression by targeting PDK1/PI3K/AKT pathway, potentiating the use of miR-503 as a biomarker and therapeutic target for NSCLC.
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.
We assessed whether buparlisib, a class 1 PI3K inhibitor, can be safely combined with radiotherapy in patients with non-small cell lung carcinoma (NSCLC) and investigated its effect on tumour hypoxia.
