Project description:To explore the effect of Ptenα on antiviral immunity pathway, we conducted RNA transcriptome profiling of wild-type and Ptenα-/- MEFs (mouse embryonic fibroblast cells) in response to VSV (vesicular stomatitis virus)
Project description:To determine whether PTENα directly binds to viral RNA, we performed Cross-Linking and Immunoprecipitation (CLIP) sequencing of HEK293T cells transfected with vector encoding PTENα under VSV (vesicular stomatitis virus) infection
Project description:To explore the binding sites of PTENα on viral or host RNAs, we performed HyperTRIBE assay of HEK293T cells overexpressing ADAR1-CD, PTENα-N(WT)-ADAR1-CD, or PTENα-N(6R/D)-ADAR1-CD fusion protein under VSV-GFP (green fluorescent protein-expressing vesicular stomatitis virus) infection.
Project description:Stress granules are known to be related with selective translation. To determine which proteins are regulated by stress granules assembly in Ptenα─/─ MEFs, we performed a mass spectrometry analysis of Ptenα+/+ and Ptenα─/─ MEFs under oxidative stress.
Project description:In contrast to the ubiquitous expression profile of PTEN, PTENα is predominantly expressed in brain. To study the biological function of PTENα in brain, we employed LCMV to induce murine viral encephalitis model. Through single cell RNA sequencing, we revealed the immunological function of PTENα during viral infection in the brain.
