Project description:Combinatorial knock down of LHX9, OSR1, PRRX1, TWIST2, fibroblast specific transcription factors and adipogenic induction by medium change induce transdifferentiation from fibroblast to adipocyte. Adipogenesis from meshencymal stem cell (MSC) and human preadipocyte (PreADP) were used for general reference of adipogenesis. 54 Samples total with 3 replicates each of sample and treatment types.

Project description:MicroRNAs (miRNAs) have been globally profiled in cancers but there tends to be poor agreement between studies including in the same cancers. Additionally, few putative miRNA targets have been validated. To overcome the lack of reproducibility, we profiled miRNAs by next generation sequencing and locked nucleic acid miRNA microarrays, and we verified concordant changes by quantitative RT-PCR. Notably, miR-125b and the miR-99 family members miR-99a, -99b, -100 were down-regulated in all assays in advanced prostate cancer cell lines relative to the parental cell lines from which they were derived. All four miRNAs were also down-regulated in human prostate tumor tissue compared to normal prostate. Transfection of miR-99a, -99b or -100 inhibited the growth of prostate cancer cells and decreased the expression of prostate-specific antigen (PSA), suggesting potential roles as tumor suppressors in this setting. To identify targets of these miRNAs, we combined computational prediction of potential targets with experimental validation by microarray and polyribosomal loading analysis. Three direct targets of the miR-99 family that were validated in this manner were the chromatin remodeling factors SMARCA5 and SMARCD1 and the growth regulatory kinase mTOR. We determined that PSA is post-transcriptionally regulated by the miR-99 family members at least partially by repression of SMARCA5. Together, our findings suggest key functions and targets of miR-99 family members in prostate cancer suppression and prognosis. C4-2 cells were transfected with miR-99a and harvested after 48hr. si-GL2 was used as control.

Project description:To investigate the effect of ZNF395 on adipogenesis, we tested whether ZNF395 enhance cell conversion from human dermal Fibroblast (FIB) to Adipocyte (ADP). PPARG2 was reported as a master regulator and can induce adipogenesis in non-adipogenic fibroblasts. We transduced PPARG2 with or without ZNF395 in FIB with lentivirus. Interestingly, co-transduction of PPARG2 and ZNF395 showed higher occurrence of adipocyte-like cells as compared with PPARG2 alone. Moreover, genes related with lipid metabolic process and lipid transport was significantly up-regulated in combination of PPARG2 and ZNF395. These results suggest that ZNF395 co-ordinate the transcriptional regulatory pathway with PPARG2, necessary for the induction of adipogenesis. Total RNA was obteined from human dermal fibroblast transduced with mock lentivirus vector (FIB_ctrl), PPARG2 (FIB_PPARG2) and co-transduced with PPARG2 and ZNF395 (FIB_PPARG2+ZNF395).

Project description:Although cancer associated fibroblasts (CAF) play a critical role in cancer progression, their identities are still unknown. Because cells’ own identity is determined by core regulatory circuit (CRC) comprising master transcription factors (TFs), it is critical to find CAF’s master TF. Therefore, we attempt to find master TF of CAF through the extensive screening of single cell RNA-seq database of cancer tissues, and discovered Prrx1, master regulator of embryonic mesenchymal cells, as candidate for master TF of CAF. Prrx1 was abundantly expressed in CAFs with significant correlation with unfavorable clinical outcomes. Furthermore, Prrx1 in fibroblasts dramatically enhanced tumor progression and metastasis in fibroblast-specific Prrx1 inducible mice. On the other hand, tumor formation was severely inhibited in conditional Prrx1 knock-down mice. Finally, we confirmed that Prrx1 is a master TF of CAF and normal fibroblast executing wound healing program using ChIP-SEQ, CRC modeling, and in vivo validation. Furthermore we also revealed that targeting Prrx1 in fibroblast alone induced complete remission of chemotherapy-resistant cancer in preclinical mouse experiments.
