Project description:HDAC5 belongs to Class IIa histone deacetylases and forms corepressor complex with HDAC3 to suppess gene expression. To identify the target genes of HDAC5, we performed ChIP-seq analysis in FLAG-tagged HDAC5 PDAC escaper cells. HDAC5 binding chromatins were pulled down by HDAC5 antibody and FLAG antibody as replicates.
Project description:HDAC5 drives PDAC cells to bypass KRAS* dependency. To dissect the molecular mechanisms that regulated by overexpressed HDAC5 in the bypass of KRAS* dependency, we conducted RNA-seq analysis of HDAC5 escaper PDAC cells and KRAS*-expressing iKPC PDAC cells.
Project description:HDAC5 drives PDAC cells to bypass KRAS* dependency. To dissect the molecular mechanisms that regulated by overexpressed HDAC5 in escaper cells, we conducted RNA-seq analysis of HDAC5 escaper PDAC cells knocking down of HDAC5 or scramble shRNA control.
Project description:HDAC5 belongs to Class IIa histone deacetylases and forms corepressor complex with HDAC3. To understand the epignetic regulations by HDAC5, we performed ChIP-seq analysis of H3K4me3, H3K27ac and H3K9ac in PDAC cells overexpressing GFP or HDAC5, and in HDAC5 escaper cells with HDAC5 knockdown or scramble control.
Project description:KRAS mutation is the most frequently mutated oncogene, occurring in approximately 90% of patients with PDAC, where KRASG12D is the most common allele in PDAC. Recent studies revealed that KRASG12D mutation caused the aberrant gene expression profile by regulating RNA processing to drive tumor progression (9, 17). However, the role of the KRASG12D mutation in triggering the circRNA process during tumor development remains unknown. Our study aims to explore the genes that regulates circRNA biogenesis in the LN metastasis of PDAC.
Project description:Hierarchical clustering of pancreatic cancer cell lines based on differentially regulated genes between mesenchymal and epithelial PDAC cells derived from primary tumours and metastases from KrasG12D-driven mouse models of pancreatic cancer.
Project description:We analyzed chromatin accessibility genome wide in EZH2KO and control cells derived from PDAC tumors of KrasG12D/PEC-IkkαΔPEC PDAC model mice to gain insight how the ablation of EZH2 affects the accessibility of genes involved in PDAC tumorigenesis.
