Hypoxia-induced p53 modulates both apoptosis and radiosensitivity via AKT.
In J Clin Invest, Jun 2015
Evaluation of hypoxia-induced transcripts in multiple cell lines identified a group of genes that are hypoxia-inducible proapoptotic targets of p53, including inositol polyphosphate-5-phosphatase (INPP5D), pleckstrin domain-containing A3 (PHLDA3), sulfatase 2 (SULF2), B cell translocation gene 2 (BTG2), cytoplasmic FMR1-interacting protein 2 (CYFIP2), and KN motif and ankyrin repeat domains 3 (KANK3).
Proposed megakaryocytic regulon of p53: the genes engaged to control cell cycle and apoptosis during megakaryocytic differentiation.
Evanston, United States. In Physiol Genomics, 2012
Among substantially downregulated p53 targets in p53-KD megakaryocytes were cell cycle regulators CDKN1A (p21) and PLK2, proapoptotic FAS, TNFRSF10B, CASP8, NOTCH1, TP53INP1, TP53I3, DRAM1, ZMAT3 and PHLDA3, DNA-damage-related RRM2B and SESN1, and actin component ACTA2, while antiapoptotic CKS1B, BCL2, GTSE1, and p53 family member TP63 were upregulated in p53-KD cells.
Global methylation profiling for risk prediction of prostate cancer.
Rochester, United States. In Clin Cancer Res, 2012
Validation of genes by pyrosequencing from group 1 (GSTP1, HIF3A, HAAO, and RARβ), group 2 (CRIP1, FLNC, RASGRF2, RUNX3, and HS3ST2), group 3 (PHLDA3, RASGRF2, and TNFRSF10D), and group 4 (BCL11B, POU3F3, and RASGRF2) confirmed the microarray results.
Physiological regulation of Akt activity and stability.
In Am J Transl Res, 2009
This literature review details findings of those reports and others relevant to the regulation of Akt activation by its upstream kinases, with a focus on mammalian target of rapamycin complexes (mTORCs) and inactivation by PHLDA3 and the protein phosphatases PP2A and pleckstrin homology domain leucine-rich repeat protein phosphatase (PHLPP).
Microarray analysis of prothrombin knockdown in zebrafish.
San Antonio, United States. In Blood Cells Mol Dis, 2009
One particular gene, phlda3, was at least eleven fold upregulated, and in situ hybridization revealed expansion of phlda3 expression in the central nervous system, branchial arches, and head endoderm in knockdown embryos.
RVB1/RVB2: running rings around molecular biology.
Charlottesville, United States. In Mol Cell, 2009
RVB1/RVB2 (also known as Pontin/Reptin, TIP49/TIP48, RuvbL1/RuvbL2, ECP54/ECP51, INO80H/INO80J, TIH1/TIH2, and TIP49A/TIP49B) are two highly conserved members of the AAA+ family that are present in different protein and nucleoprotein complexes.
PH domain-only protein PHLDA3 is a p53-regulated repressor of Akt.
Tokyo, Japan. In Cell, 2009
Study identifies PHLDA3 as a p53 target gene that encodes a PH domain-only protein and finds that PHLDA3 competes with the PH domain of Akt for binding of membrane lipids, inhibiting Akt translocation to the cellular membrane and activation.
A p53-dominant transcriptional response to cisplatin in testicular germ cell tumor-derived human embryonal carcinoma.
United States. In Oncogene, 2005
Several of these gene products, including FAS, TRAILR3, PHLDA3, LRDD, and IER3 are previously implicated in the apoptotic death receptor pathway, while others including SESN1, FDXR, PLK3, and DDIT4 are known mediators of reactive oxygen species generation.
