Our results suggest that TOPK is a potential therapeutic target in lung cancer that promotes cell migration by modulating a PI3K/PTEN/AKT-dependent signaling pathway; they also suggest that high TOPK expression, either alone or in combination with a low level of PTEN, may serve as a prognostic marker for lung cancer.
INSM1 functions as a key player in NE lung cancer via Shh signaling that crosstalk with PI3K/AKT and MEK/ERK<sup>1/2</sup> pathway to enhance N-myc stability in NE lung cancer.
Here, we reported that the AKT inhibitor perifosine and the MEKERK inhibitor MEK-162 synergistically induced lung cancer cell (A549 and H460 lines) growth inhibition and apoptosis.
Our data provide evidence that, although AKT1 mutations are apparently rare in lung cancer (1.9%), the oncogenic properties of E17K-AKT1 may contribute to the development of a fraction of lung carcinoma with squamous histotype (5.5%).
In surveying a number of tumor types for differences in intrinsic levels of HIF under hypoxia, we find that the reduction of the upstream pathways of HIF, AKT, and mammalian target of rapamycin (mTOR) correlates with increased toxic effects of 2-deoxy-D-glucose (2-DG) in lung cancer cell lines when treated under hypoxia.
Here, we utilize a bioluminescence reporter for AKT kinase activity (BAR) to noninvasively assess the therapeutic efficacy of the EGFR inhibitor erlotinib in KRAS-mutated lung cancer therapy.
In this manuscript, we sought to determine whether this AKT1 variant is a bona-fide activating mutation and plays a role in the development of 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.
The combination of an AKT inhibitor and cisplatin efficiently suppressed lung cancer cell growth both <i>in vitro</i> and <i>in vivo</i> Our study illustrated an upstream regulatory mechanism of FEN1, which will contribute to the development of effective lung cancer therapies.These findings identified AKT as a regulator of FEN1 activity and revealed the AKT signaling pathway's contribution to drug resistance, which will contribute to the development of effective lung cancer therapy.
Furthermore, meta-analysis showed the correlation between LINK-A expression and incidence of a single nucleotide polymorphism (rs12095274: A > G), AKT phosphorylation status, and poor outcomes for breast and lung cancer patients.
Overexpression of Akt1 restores cancerous growth of A549 cells in B23-knockdown (KD) cells while Akt2 overexpression did not restore proliferating potential in cells with downregulated B23, thus suggesting Akt2 requires B23 to drive proliferation of lung cancer cell.
For example, multiple downstream components of the EGFR-family-signaling pathway, including CDK5, AKT1 and SHC1, are overexpressed as a direct result of gene amplification in lung cancer.
We showed that RBL2/p130 and AKT1 physically interact and AKT phosphorylates RBL2/p130 Ser941, located in the pocket domain, but not when this residue is mutated into Ala. We found that pharmacological inhibition of AKT, through the highly selective AKT inhibitor VIII (AKTiVIII), impairs RBL2/p130 Ser941 phosphorylation and increases RBL2/p130 stability, mRNA expression and nuclear levels in both lung cancer and mesothelioma cell lines, mirroring the more extensively studied effects on the p27 cell-cycle inhibitor.
The aim of the present study was to investigate the effect of short hairpin (sh)RNA targeting AKT1 and phosphatidylinositol 3-kinase (PI3K)/p85 on the proliferation and self-renewal of lung cancer stem cells (LCSCs).
Genetic variants in the PI3K/PTEN/AKT/mTOR pathway predict platinum-based chemotherapy response of advanced non-small cell lung cancers in a Chinese population.
