20. 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.

Human Phosphoinositide-3-Kinase, Catalytic, alpha Polypeptide (PIK3CA) interaction partners

2. This study determined the mutation frequencies and prognostic values of KRAS exon 2, 3 and 4, NRAS exon 2 and 3, PIK3CA exon 9 and 20, and BRAF exon 15 by PCR and direct sequencing in 353 colorectal cancer patients from two Chinese clinical centers.

3. Study shows that ARQ092 counteracts overactivation of PI3K signal pathway in primary fibroblast cells derived from patients with PIK3CA-related overgrowth spectrum.

4. We detected the same PIK3CA mutation in her affected tissue, urine, and tumor, indicating Wilms tumors probably arise from PIK3CA mutant cells in patients with CLOVES. No urine sample from a participant with Klippel-Trenaunay (KTS) had detectable PIK3CA mutations.

To investigate the reasons for which miR-375 holds a special place among circulating miRNAs in Acute myocardial infarction (MI), enrichment and network analyses of miR-375 target genes and their interactions were carried out. PIK3CA and TP53 genes, regulated by miR-375, were identified as the key players of MI disease module.

7. We report the first characterization of clinical acquired resistance to MEKi + CDK4i, identifying a rare preexisting PIK3CA(E545K) subpopulation that expands upon therapy and exhibits drug resistance.
