ProteomicsElucidating PTEN Conformational Dynamics and Phosphatase Regulation via Integrative Modeling and Mutation Prediction
PTEN (Phosphatase and TENsin homolog deleted on chromosome ten) is a major tumor suppressor gene that is frequently mutated or lost under cancerous conditions. PTEN is a dual-specificity phosphatase that negatively regulates the PI3K/AKT/mTOR signaling pathway at the plasma membrane (PM). Its functi...

TranscriptomicsTranscription profiling of mouse model of intestinal polyposis PTEN-deficient mutant reveals intestinal stem cells initiate intestinal polyposis
Intestinal polyposis, a precancerous neoplasia, results primarily from an abnormal increase in the number of crypts. Crypts contain intestinal stem cells (ISCs). Thus intestinal polyposis provides an ideal condition for studying stem cell involvement in polyp/tumor formation. Using a conditional kno...

TranscriptomicsFunctional properties of PTEN and PTEN mutants in U87MG glioblastoma cells
To investigate the effects of PTEN activity on gene expression in 3D cultured glioblastoma cells and the contributions of PTEN's lipid and protein phosphatase activities to these effects. We expressed wild type PTEN, a catalytically dead mutant (C124S) or mutants selectively lacking protein or lipid...

TranscriptomicsBiallelic and complicated inactivation of Pten in radiation-induced mouse thymic lymphomas
Inactivation of Pten occurs by multiple mechanisms including epigenetic silencing, point mutations, insertion, and deletion, which are tissue dependent. Although frequent loss of heterozygosity around Pten locus and plausible involvement of epigenetic silencing have been reported in radiation-induce...

ProteomicsPhosphoproteomics of MEFs with loss-of-function PTEN mutations
The PTEN tumor suppressor controls cell death and survival by regulating functions of various molecular targets. Whilst the role of PTEN lipid-phosphatase activity on PtdIns(3,4,5)P3 and inhibition of PI3K pathway is well characterized, the biological relevance of PTEN protein-phosphatase activity r...

TranscriptomicsTranscription profiling of human HCT116 PTEN+/+ cell lines and three independently-derived HCT116 PTEN-/- cell lines
In an effort to identify genes whose expression is regulated by activated PI3K signaling, we performed microarray analysis and subsequent qRT-PCR on an isogenic set of PTEN gene-targeted human cancer cells. Numerous p53 effectors were upregulated following PTEN deletion, including p21, GDF15, PIG3, ...

TranscriptomicsFOXO1/3 and PTEN Depletion in Granulosa Cells Promotes Ovarian Granulosa Cell Tumor Development
The Forkhead Box, FOXO1 and FOXO3, transcription factors regulate multiple functions in mammalian cells. Selective inactivation of the Foxo1 and Foxo3 genes in murine ovarian granulosa cells severely impairs follicular development and apoptosis causing infertility, and as shown herein, granulosa cel...

TranscriptomicsPTEN intact and NULL prostates in intact and castrate mice.
We performed expression profiling of prostates of 3 month wild-type and PTEN NULL mice and assessed the response to 3 days of castration. Seven three month old WT and PbCre x PTEN f/f (PTEN NULL) mice were used. They are in the C57B6 background. Three mice in each group were castrated. Three days af...

ModelsPhosphatase activities on PI(3,4,5)P3 and PI(3,4)P2
Phosphatase activities on PI(3,4,5)P3 and PI(3,4)P2 This model describes the action of various phosphatases on PI(3,4,5)P3 and PI(3,4)P2, in response to a stimulation by EGF. It contains boolean switches to simulate knock-down and knock-out of phosphatases as well as inhibition of PI3 kinase. ...
