We genotyped 70 genes involved in the pathogenesis of renal-cell carcinoma (including the VHL/HIF/VEGF and PI3K/AKT/mTOR pathways, and genes involved in immune regulation and metabolism) for single nucleotide polymorphisms.
Together, our study reveals a novel mechanism of PI3K-AKT inhibition-mediated feedback regulation and may identify FoxO as a novel biomarker to stratify patients with RCC for PI3K or AKT inhibitor treatment, or a novel therapeutic target to synergize with PI3K-AKT inhibition in RCC treatment.
In this study, we identified miR-30d as a downstream effector of the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway in renal cell carcinoma (RCC) cells.
A novel HDAC inhibitor OBP-801 and a PI3K inhibitor LY294002 synergistically induce apoptosis via the suppression of survivin and XIAP in renal cell carcinoma.
We genotyped 70 genes involved in the pathogenesis of renal-cell carcinoma (including the VHL/HIF/VEGF and PI3K/AKT/mTOR pathways, and genes involved in immune regulation and metabolism) for single nucleotide polymorphisms.
This study proposes a novel treatment paradigm where combining PI3K/AKT/mTOR pathway inhibitors and autophagy inhibitors lead to enhanced RCC cell apoptosis.
The PI3K/Akt pathway and other pathways associated with cyclins, DNA replication and cell cycle/mitotic regulation were also associated with the synergy of DAC and PTX against RCC.
Using specific inhibitors of phosphoinositide 3-kinase (PI3K) and depletion of Akt kinase by RNA interference, we established that PTHrP is one of the main factor involved in the constitutive activation of this pathway in human RCC, independently of von Hippel-Lindau (VHL) tumor suppressor gene expression.
