Project description:We used microarrays to study the global gene expression and identified differentially expressed genes in PTEN knockout SF763 cells, aiming to identify genes and pathways that are regulated by PTEN.
Project description:MicroRNA profiling in Pten knockout mouse thymus cells. microRNAs (miRs) are short noncoding RNAs of 20â22 nucleotides that function to regulate gene expression at the posttranscriptional level. They play fundamental roles in the regulation of cellular proliferation, differentiation, and apoptosis. miRs are dysregulated in many types of cancer, including T-ALL (T cell lymphoblastic leukemia). miRs can function as oncogenes, favoring the initiation and progression of cancers, or as tumor suppressors, preventing tumorigenesis. The biological functions of miRs in T-ALL are largely unknown. In human T-ALL patients, recurrent mutations in the Phosphatase and tensin homolog (PTEN) gene are common, consistent with Pten-knockout mice developing T-ALL. To better understand T-ALL pathogenesis and identify new therapeutic targets in T-ALL, we developed a Pten-knockout T-ALL mouse model and the mice developed T-ALL within 3 months as expected. We profiled the miRs in the Pten-deficient mouse T-ALL. A576, A577, A578 and A579 are PTEN-knockout mouse T-ALL samples. A580 andA 581 are wild-type mouse thymocytes.
Project description:The goal of this study was to perform transcriptomics on wildtype, PTEN single knockout (SKO) and PTEN;Rb1 double knockout (DKO) mouse prostate organoids. We isolated basal cells from PTEN floxed and PTEN;Rb1 floxed mouse prostates and infected with either RFP control or Cre recombinase to establish wildtype, SKO, and DKO mouse prostate organoids.
Project description:extracellular PTEN treatment did not affect the growth of PTEN knockout B16-F10 cells cultured in vitro. , To investigate whether extracellular PTEN act on the tumor microenvironment to exert a tumor-suppressive role in vivo,molecular changes caused by PTEN treatment inside the B16-F10-PTEN tumors were monitored by RNA sequencing.

WT (n=3). B. Pten-/- (n=4). C. Pten-/- Tgfbr2-/- (n=4).
Project description:PTEN treatment can affect the tumor growth of PTEN knockout B16-F10 cells in C57BL/6J mice,We hope to analyze the changes that occur in various cells in tumors through single-cell RNA sequencing.

Project description:We used microarrays to analyze the global gene expression and to identify the differentially expressed genes among wild type, prostate-specific Pten knockout, and prostate-specific Pten and Pml double knockout prostates at 12 weeks of age.
