Isoginkgetin induces autophagic cell death in hepatocellular carcinoma [ChIP-seq 2]

ABSTRACT: Purpose: Our previous studies have identified isoginkgetin as an inducer of autophagic cell death in hepatocellular carcinoma. We set out to analyze how isoginkgetin regulates the genome-wide enhancer activity in HepG2 cells. Methods: ChIP-seqs for H3K4me, H4K8ac, H3K27me3 and H3K9ac were performed in HepG2 followed by treatment with 20 μM isoginkgetin for 24 h. Conclusions: Isoginkgetin treatment reduces the expression of glucose transporters and inhibts SLC2A1 enhancer activity in HepG2 cells.

Isoginkgetin induces autophagic cell death in hepatocellular carcinoma [RNA-Seq]

Project description:Purpose: Our previous studies have identified Isoginkgetin as an inducer of autophagic cell death in hepatocellular carcinoma. We set out to analyze how isoginkgetin regulates gene expression in HepG2 cells. Methods: RNA-seq was performed with two repetitions in HepG2 followed by treatment with DMSO and 20 μM Isoginkgetin for 24 h. Conclusions: Isoginkgetin treatment reduces the expression of glucose transporters in HepG2 cells.

A total RNA-Seq screen reveals that the splicing inhibitor Isoginkgetin blocks transcription elongation

Project description:Pharmacological perturbation is a powerful tool for understanding gene expression, but identification of the specific steps of this multi-step process targeted by small molecules remains challenging. Here we apply total RNA-Seq to distinguish specific pharmacological effects on transcription and pre-mRNA processing, revealing unexpectedly that the splicing inhibitor isoginkgetin blocks transcription elongation.An RNA-Seq screen reveals that the compounds TBBz and CYT387 mimic the transcriptional effects of isoginkgetin and are inhibitors of CSNK2A2, suggesting that isoginkgetin blocks transcription elongation via inhibition of CSNK2A2. Our results reveal RNA-Seq screening as a tool for disentangling complex pharmacological effects on gene expression.

Microarray analysis of isoginkgetin-treated HCT116 and HCT116p53-/- cells

Project description:Isoginkgetin (IGG) is a small molecule inhibitor of the spliceosome although the direct target remains elusive. Widespread failure to accurately remove introns poses a risk to cells and organisms through the potential production of aberrant mRNAs and proteins. The cellular responses to accumulation of these intermediates and/or the direct interference of spliceosome assembly itself may constitute a splicing stress but this is not well defined yet. We used oligonucleotide microarrays to assess genome wide changes in gene expression associated with exposure to IGG in HCT116 cells and an isogenic subline lacking the p53 tumor suppressor that responds to a variety of transcriptional stresses (Oncogene 18 (3), 583-592). Two of the 3 enriched pathways identified using PANTHER analysis of differentially expressed transcripts are linked to the ATF4 transcription factor and these effects are p53-independent.
