Dual molecular targeted therapy for mTOR and PI3K may be a promising therapeutic strategy in the specific population of patients with lung cancer with LKB1 loss.
Mutations in EGFR, KRAS, BRAF, and PIK3CA genes are widely analyzed in solid tumors such as lung cancer, colorectal cancer, breast cancer, and melanoma.
Therefore, targeting the PI3K pathway may be a potential therapeutic strategy that prevents the structural skeletal damage associated with bone metastasis of lung cancer.
Consistently, DOK7V1 overexpression in lung cancer cells suppressed the phosphoinositide 3‑kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathways, but activated the focal adhesion kinase (FAK)/paxillin signaling pathway.
The phosphoinositide 3-kinase (PI3K)/AKT/mechanistic target of rapamycin (mTOR) signaling has been shown to contribute to tumorigenesis, tumor progression, and resistance to therapy in most human cancer types, including lung cancer.
Our studies suggest that miR-183-5p may function as a tumor suppressor in lung cancer via the miR-183-5p/PIK3CA regulatory axis and identify a potentially effective therapeutic strategy for lung cancer.
Finally, we identified that the PI3K-AKT and epilthelial-mesenchymal transition (EMT) signaling pathways were inhibited by miR-3666 overexpression in lung cancer cells.
Furthermore, cotreatment with sesamin and CAY10404 markedly reduced the levels of phosphorylated protein kinase B (pAkt) and phosoinositide 3 kinase (PI3K) in three lung cancer cell lines.
All of these results suggested that the lncRNA FER1L4 suppressed cell proliferation and metastasis by inhibiting the PI3K/Akt signaling pathway in lung cancer.
Methyl nonanoate, (R)-citronellol, cis-carveol (L-carveol), 3-methyl-Cyclohexanone, 4-carene and thujopsene were finally screened for PI3K targeted anti-cancer therapies which may find direct application as inhalers or sprays against lung cancer as these compounds are highly volatile.
The effect of paclitaxel combined with lobaplatin on the sensitivity of lung cancer cell line NCI-H446 through influencing the phosphatidylinositol 3-kinase (PI3K)/Akt pathway was investigated.
RAS signaling through PI3K is necessary for normal lymphatic vasculature development and for RAS-induced transformation in vitro and in vivo, especially in lung cancer, where it is essential for tumor initiation and necessary for tumor maintenance.
Taken together, these findings demonstrate that PI3K/AKT/YY1 is involved in the regulation of lung cancer cell behavior induced by IL‑13, and miR‑29a represents a promising therapeutic target.
