Here, we demonstrated that inducible MuSC-specific deletion of p110alpha, a catalytic subunit of phosphatidylinositol 3-kinase (PI3K), rendered MuSCs unable to exit quiescence, resulting in severely impaired MuSC proliferation and muscle regeneration.
miR152 may have an important role in pancreatic beta cell function, and established an association between miR152 and the PI3Kalpha axis.
H1047R mutation of Pik3ca induces centrosome amplification in cultured mouse cells.
The crucial role of p110beta and the more subtle role of p110alpha in the production of PIP3 molecular species following platelet stimulation has been demonstrated.
Here, we describe a role for PI3K/AKT in the regulation of TRF1, an essential component of the shelterin complex. PI3K and AKT chemical inhibitors reduce TRF1 telomeric foci and lead to increased telomeric DNA damage and fragility. We identify the PI3Kalpha isoform as responsible for this TRF1 inhibition.
The data establish oncogenic PIK3CA mutations as a cause of glutamine dependency in colorectal cancer.
High PI3k expression is associated with gastrointestinal stromal tumor.
High PI3K expression is sensitive to initial injury intensity induced by freeze damage.
excessive proliferation of endometrial epithelial cells was observed in Pik3cad/d mice. Our studies suggest that Pik3ca has a critical role in uterine gland development and female fertility
Long latency DMBA induced mouse mammary tumors reproduce the molecular profile of human luminal breast carcinomas, displaying a high incidence of activating Pik3caH1047 and loss of function Pten mutations.
Data show that the phosphoinositide 3-kinase (PI3K) inhibitor BKM120 led to a precipitous drop in DNA synthesis within 8 h of drug treatment, whereas DNA synthesis in normal tissues was less affected.
Using genetic inactivation of the growth and metabolism regulator, Pik3ca (encoding PIK3CA also known as p110alpha, alpha/+), the interplay between the maternal genome and the fetal genome on placental phenotype, was examined.
these results identify the PI3K-GSK3-SMAD1 axis as a central node integrating multiple signaling networks that govern bone formation and homeostasis.
Study identified a novel F977Y kinase domain PIK3CA mutation exclusively present in a recurrent cell line of head and neck squamous cell carcinoma (HNSCC), potentially conferring resistance to PI3K inhibitors.
KRAS wild-type metastatic colorectal cancer patients with mutant type phosphatidylinositol 3-kinases receiving an epidermal growth factor receptor monoclonal antibody (anti-EGFR) inhibitor as first-line therapy have significantly lower overall response rate, shorter progression-free survival and overall survival.
The study shows a high concordance of KRAS, NRAS, BRAF and PIK3CA gene mutations in plasma against mutation status in tumor tissue.
Study data from human hepatocellular carcinoma (HCC) liver samples, human HCC cells, and Sgk3 knockout mice model suggest that SGK3 plays a role in transducing helical domain mutant PIK3CA signaling during liver tumor development.
AR + /FOXA1 + expression defines a luminal-like TNBC subgroup affected with a worse outcome compared to other TNBC and a higher risk of late recurrences. This subgroup appears enriched in PIK3CA mutations, suggesting a role for PI3K inhibitors in this subgroup.
PIK3CA expression in triple negative breast cancer is not associated with specific clinical or diagnostic features. Further molecular studies and meta-analysis are warranted to clarify the prognostic and predictive role of PIK3CA protein expression.
In this large pooled analysis, PIK3CA mutations were significantly associated with a better IDFS, DDFS, and OS, but had a lesser prognostic effect after adjustment for other prognostic factors.

The expression levels of ARID1A and PIK3CA in gastric cancer were significantly associated with the depth of invasion of gastric cancer.
While PIK3CA mutations generally had no impact on survival, and were not associated with clinicopathological variables, patients with exon 9 charge-changing mutations were associated with poor survival in endometrial primary tumors. PIK3CA mRNA levels were increased in metastases compared to the primary tumors, independent of PIK3CA mutation status, which rather associated with reduced PIK3CA mRNA expression.
The ARID1A and PIK3CA were the most frequently mutated genes. Specifically, ARID1A mutations and PIK3CA mutations were detected in 77.8% and 66.7% of ovarian clear cell carcinoma patients, respectively. Mutations in other genes, including MLH1 (6.3%) and CREBBP (6.3%), were detected in the Taiwanese population.
These results suggest that in addition to overgrowth of bone and soft tissue, gain of function variants in PIK3CA may predispose to overgrowth of scar tissue, resulting in the formation of abnormal scars such as keloids or hypertrophic scars.
biomarkers that are predictive of a response, such as PIK3CA mutations for inhibitors of the PI3K catalytic subunit alpha isoform, must be identified and analytically and clinically validated.. we review the current experience with anticancer therapies that target the PI3K-AKT-mTOR pathway.
Authors used six whole-exome-sequenced primary HGSOC/USC cell-lines and three xenografts overexpressing HER2/neu and harboring mutated or wild-type PIK3CA/PIK3R1 genes to evaluate the role of PI3K-mutations as potential mechanism of resistance to afatinib.

crystallographic and biochemical approaches used to gain insight into activating mutations in two noncatalytic p110alpha domains-the adaptor-binding and the helical domains
Phosphatidylinositol 3-kinase is composed of an 85 kDa regulatory subunit and a 110 kDa catalytic subunit. The protein encoded by this gene represents the catalytic subunit, which uses ATP to phosphorylate PtdIns, PtdIns4P and PtdIns(4,5)P2. This gene has been found to be oncogenic and has been implicated in cervical cancers.
