Phospholipase C-related catalytically inactive protein (PRIP)-deficient mouse embryonic fibroblasts exhibited increased cell migration, and was significantly attenuated upon transfection with a siRNA targeting p110alpha, a catalytic subunit of class I phosphoinositide 3-kinases (PIK3CA).
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

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.
Data suggest a critical role for KDM3A in the PI3K/AP-1 oncogenic axis and propose a novel strategy for inhibition of KDM3A against liver tumor development under PI3K pathway activation.
Data show that tumors lacking PSMA had less than half the abundance of type 1 insulin-like growth factor receptor (IGF-1R), less activity in the survival pathway mediated by PI3K-AKT signaling, and more activity in the proliferative pathway mediated by MAPK-ERK1/2 signaling.
Both PIK3CA mutants H1047R and E545K are able to activate the AKT/mTOR pathway. An intact AKT2/mTOR complex 1 cascade is required for tumourigenesis induced by H1047R/c-Met or E545K/c-Met in the liver in mice.
Loss of HDAC-mediated repression and gain of NF-kappaB activation underlie cytokine induction in ARID1A- and PIK3CA-mutation-driven ovarian cancer.
We further demonstrate that loss of one allele of PTEN is sufficient to shift isoform dependency from p110alpha to p110beta in vivo. These results provide insight into the molecular mechanism by which ErbB2-positive breast cancer escapes p110alpha inhibition.
Studies indicate that the Pten+/- genotype displayed neoplasia in multiple organs, including the endometrium and that the Pten is a key regulatory player in the PI3K/PTEN/AKT pathway.
This study detected gain-of-function mutations in exon 20 of PI3KCA gene in 11% of gastric cancer patients.
These results suggest that the classical metabolic PI3K pathway and not the canonical proliferation ERK pathway is involved in the insulin/insulin-like growth factor-1-induced increase in crypt proliferation in obese humans, which may contribute to abnormal tissue renewal and function.
The pooled analysis confirmed that the presence of a PIK3CA mutation represents an independent negative prognostic factor (HR = 1.67, 95%CI: 1.15-2.43; P = 0.007) in BC, as previously reported. As PI3K signaling is also a result of other pathways' hyperactivation.
High PIK3CA expression is associated with hepatocellular carcinoma.
PIK3CA silencing inhibited Nalm-6 cell proliferation and invasion, and promoted their apoptosis and sensitivity to chemotherapeutic drugs, potentially through regulation of the PI3K/AKT signaling pathway.
findings provided a comprehensive mutation profiling of AKT1, PIK3CA, PTEN and TP53 genes in Chinese breast cancer patients, which have potential implications in clinical management.
LASP1 may function as an oncogene in glioblastoma and regulate cell proliferation and chemosensitivity in a PI3K/AKT-dependent mechanism.
Targeting activating mutations in PIK3CA assay was used for screening tumor DNA from Metastatic Relapse in Advanced Bladder Cancer patients; at least one mutation was detected in 19 of the 60 patients.
Six mutations located at the BRAF, KRAS, and PIK3CA genes have been detected in colorectal cancer patients using a novel multiplex surface enhanced Raman spectroscopy-multiplex PCR method.
Inflammatory stress displayed by endothelial cells derived from lymphatic malformation is consistent with errors in lipid metabolism that may be linked to PIK3CA acquired mutations.
Results show that activating PIK3CA mutations in lymphatic malformations are specifically localized in lymphatic endothelial cells (LECs); identified a new mutation in exon 10 and a Glu109 deletion of the gene and show that several kinase inhibitors have the potential to block LEC proliferation.
Levels of miR381 were decreased in clear cell and endometrioid carcinoma ovarian cancer. Experimentally induced upregulation of miR381 led to a decrease in the level of PIK3CA in ovarian cancer cells and inhibition of ovarian cancer cells proliferation and migration.

We identified a total of five distinct mutations in PIK3CA (NM_006218.2), including one hotspot mutation (c.1624G>A;p.Glu542Lys); two recurrent, strong (gain of function) mutations (c.3140A>T;p.His1047Leu, c.1258T>C;p.Cys420Arg); one previously described mutation in patients with macrodactyly (c.344G>C;p.Arg115Pro); and one novel somatic PIK3CA mutation (c.248T>C; p.Phe83Ser) not previously described
PIK3CA mutation in gastric cancer is a rare finding. It is strongly associated with the microsatellite instability (MSI) molecular subgroup, presenting a worse outcome than other MSI patients. A completely different outcome is associated with the mutation in exon 9 compared to the mutation in exon 20, with the latter being more favorable.
In early breast cancer, PIK3CA mutations seem to identify HER2+ patients who are less likely to reach pCR. The clinical implications of PIK3CA mutations tend to vary between exon 9 and exon 20. This mechanism should be explored in further studies.
Data show that both class I and III phosphoinositide 3-kinases (PI3Ks) re present in trafficking vesicles.

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.
