The occurrence of ARID1A mutations and alterations in the PI3K/AKT pathway in endometriosis and endometriosis-associated ovarian carcinomas, as well as the possible functional and clinical implications are discussed in this review.
Here, we outline the importance of PI3K/AKT/mTOR signaling pathway in OC tumorigenesis, proliferation and progression, and pre-clinical and clinical experience with several PI3K/AKT/mTOR pathway inhibitors in OC.
Our results indicate that FAK inhibition can suppress ovarian cancer cells migration and invasion through inhibiting downstream signaling (PI3K/AKT), which might be a therapeutic target or biomarker for ovarian cancer.
Taken all data together, these findings demonstrated that the absence of SMURF1 repressed cell proliferation, invasive capability, and EMT process in ovarian cancer through DAB2IP/AKT/Skp2 signaling loops, suggesting that SMURF1 may serve as a new potential therapeutic agent for ovarian cancer.
Importantly, we found that ΔNp63α, AKT1, and phospho-AKT levels are greater in 2008CI3 CDDP-resistant ovarian cancer cells than in 2008 CDDP-sensitive cells. siRNA-mediated knockdown of ΔNp63α expression dramatically decreased AKT1 expression, whereas knockdown of either ΔNp63α or AKT1 decreased cell proliferation and increased death of ovarian and head/neck cancer cells.
High prevalence of genetic alterations in PI3K/AKT pathway in a Middle Eastern ovarian carcinoma provides genetic evidence supporting the notion that dysregulated PI3K/AKT pathways play an important role in the pathogenesis of ovarian cancers.
The PI3K/AKT/mTOR signaling pathway is considered as a promising therapeutic target in the treatment of ovarian cancer (OC); however, inhibition of this pathway only exhibited moderate clinical efficacy when tested clinically.
This is the first evidence that Tan-Ⅰ induced apoptosis and promoted autophagy via the inactivation of PI3K/AKT/mTOR pathway on ovarian cancer and further inhibited tumour growth, which might be considered as effective strategy.
We utilized ovarian cancer cell line, Caov3, cells to investigate the effect of paclitaxel on EGFR-mediated MAP kinase and AKT activation, and the expression of survivin.
KIAA0101 activated the PI3K/AKT/mTOR signaling pathway to inhibit cisplatin-induced apoptosis and autophagy in ovarian cancer cells resulting in cisplatin resistance.
Gene composition analyses of the disrupted modules revealed five common genes (mitogen‑activated protein kinase 1, phosphoinositide 3‑kinase‑encoding catalytic 110‑KDα, AKT serine/threonine kinase 1, cyclin D1 and tumor protein P53) across the four subtypes of ovarian cancer.
Together, REDD1 and p-AKT over-expression may serve as a prognostic biomarker in OC, but KRAS mutations and REDD1 protein over-expression were not correlated in OC.
In this study, we have investigated the expression profile of 22 genes involved in the PI3K-AKT pathway in 26 high-grade ovarian carcinomas (19 serous and 7 clear cell carcinomas).
