DNA methylation data from AML12 cells during EMT

Project description:We investigated genome-wide DNA methylation during EMT in AML12 cells using comprehensive high throughput arrays for relative methylation (CHARM). We used custom Nimblegen microarrays. We isolated genomic DNA from cells at different timepoints post-TGF-β stimulation and hybridized to custom-designed Nimblegen microarrays (CHARM arrays). AML12 cells from 4 representative experiments were collected and used for the genome-wide DNA methylation analysis.

Effect of DUSP6 overexpression or knockdown on gene expression in AML12 cells

Project description:DUSP6 plays important roles in MAPK signaling pathway, but whether and how it is involved in liver funciton remains to be explored. Here, we performed RNA-seq analyses in AML12 cells where DUSP6 is disrupted. We overexpressed GFP-DUSP6 or GFP in AML12 cells, and tested the effects of DUSP6 increase on gene expression in AML12 cells. Meanwhile, we knocked down DUSP6 in AML12 cells and tested the effects of DUSP6 decrease on gene expression in AML12 cells. Taken together, we analyzed the changes of gene expression mediated by DUSP6, which provides new insights for the function of DUSP6 in liver

Fumarate hydratase orchestrates hepatic steatosis via ULK1 mediated lipophagy

Project description:Hepatic lipid homeostasis is coordinated by various metabolic pathways, such as lipogenesis, lipid uptake, storage, and oxidation. However, the underlying mechanism that orchestrates metabolic crosstalk remains unclarified. Herein, we demonstrated that fumarate hydratase (FH) functioned as an indispensable adaptor governing mitochondria metabolism and lipid droplets (LDs) degradation. Hepatic FH overexpression prevented hepatic steatosis in normal mice and ob/ob mice without interfering mitochondrial lipid oxidation and lipogenesis. Strikingly, we found that FH selectively activated lipophagy-mediated LDs lipidolysis. Mechanistically, FH interacted with ULK1 and stabilized ULK1 through preventing its ubiquitination and degradation, resulting in lipophagy activation and the elimination of hepatic lipid accumulation. Meanwhile, hepatic ULK1 deficiency abrogated the protective effects in FH-overexpressing mice. Also, we clarified that the interaction between FH and ULK1 occurred in cytoplasm, but not in mitochondria. Cytoplasmic FH was sensitive to lipids and downregulated without affecting mitochondrial FH in vivo. Moreover, the FH-ULK1 axis was identified closely associated with hepatic steatosis in human patients. Taken together, our research demonstrates a “two-side” insight of FH on hepatic lipid metabolism and provides a promising strategy for fatty liver treatment.

Central Role of ULK1 in Type I Interferon Signaling

Project description:We provide evidence that the Unc-51-like kinase 1 (ULK1) is phosphorylated and activated during engagement of the Type I IFN receptor. Our studies demonstrate that the function of ULK1 controls expression of key interferon stimulated genes (ISGs) that mediate important biological functions, including anti-viral and antineoplastic responses. Total RNA was isolated from untreated and IFNβ-treated Ulk1/2+/+ and Ulk1/2-/- mouse embryonic fibroblasts (MEFs). Cells were treated for 6 hours with or without mouse IFNβ (2500 IU/ml).

Transcription profiling of mouse AML12 hepatocytes transfected with v-erbA

Project description:The v-erbA oncogene belongs to a superfamily of transcription factors called nuclear receptors, which includes the retinoic acid receptors (RARs) responsible for mediating the effects of retinoic acid (RA). Nuclear receptors bind to specific DNA sequences in the promoter region of target genes and v-erbA is known to exert a dominant negative effect on the activity of the RARs. The repressor activity of v-erbA has been linked to the development of hepatocellular carcinoma (HCC) in a mouse model. We have used microarray analysis to identify genes differentially expressed in hepatocytes in culture (AML12 cells) stably transfected with v-erbA and exposed to RA. We have found that v-erbA can affect expression of RA-responsive genes. We have also identified a number of v-erbA-responsive genes that are known to be involved in carcinogenesis and which may play a role in the development of HCC. Experiment Overall Design: AML12 control cells and v-erbA-transfected AML12 cells were exposed to 1 ÂµM RA for 3h or 24h. Using microarray analysis, we compared gene expression in the presence and absence of v-erbA and identified RA-regulated genes differentially expressed in the presence of v-erbA.
