Differential protein expression between ESCC and normal tissues

Project description:To understand the difference of protein expression between paired esophageal squamous cell carcinoma (ESCC) and adjacent normal tissues, we collected 10 paired ESCC and normal tissues from surgical resected specimems for high-throughput proteomic experiments. From comparative analysis, the dysregulated signaling pathways in ESCC could be uncovered.

Expression data from EI24 knockdown in ESCC cells

Project description:Analysis of TE-1 cells following knockdown of EI24 and control vector. Etoposide induced 2.4 kb transcript (EI24), also known as p53-induced gene 8 (PIG8), is located on human chromosome 11q23. Serving as a p53 responsive pro-apoptotic factor, EI24 plays a pivotal role in inhibiting cell growth and activating autophagy and is associated with drug resistance. Results provide insight into the role of EI24 in cell proliferation and drug resistance of ESCC cells.

Characterizing the contrasting roles of JMJD3 and UTX histone demethylases in T cell acute lymphoblastic leukemia [short_hairpins_RNA-seq]

Project description:T-cell acute lymphoblastic leukemia (T-ALL) is an immature hematopoietic malignancy driven mainly by oncogenic activation of NOTCH1 signaling. In this study we abrogated the expression of JMJD3 (KDM6B) and UTX (KDM6A) H3K27me3 demethylases in human T-ALL lines and assayed for genome-wide expression changes using RNA sequencing. This piece of data was further integrated to ChIP-Sequencing analysis of H3K27me3 from the same treatment as well as H3K27me3 and JMJD3 genome-wide analysis from treatment of T-ALL lines with the GSKJ4 inhibitor. These results, coupled to genomic analysis of primary samples for the genomic status of the UTX gene in T-ALL, helped us to identify a hitherto unknown role of JMJD3as an oncogenice facilitator in leukemia whereas UTX seems to play a tumor suppressor role. Whole RNA was extracted from 1-5 million T-ALL (lines) cells or primary cells using the RNAeasy kit (Qiagen) according to the manufacturer’s protocol. Poly-A+ (magnetic oligodT-containing beads (Invitrogen)) or Ribominus RNA was used for library preparation. cDNA preparation and strand-specific library construction was performed using the dUTP method. Libraries were sequenced on the Illumina HiSeq 2000 using 50bp single-read method. Differential gene expression analysis was performed for each matched knockdown vs control pairs, separately in each biological or technical replicate in each of two cell lines (CUTLL1, CEM). Three types of comparisons were tested: (a) JMJD3 knockdown vs Renilla, (b) JMJD3 knockdown vs UTX knockdown, and (c) UTX knockdown vs Renilla. Analysis was performed using both DEGseq and Cufflinks packages leading to very similar conclusions.

Histone demethylase JMJD3 is a key epigenetic activator of FGF21 signaling-induced hepatic autophagy and lipolysis

Project description:Autophagy is essential for cellular survival and energy homeostasis under nutrient deprivation. Despite the emerging importance of nuclear events in autophagy regulation, epigenetic control of autophagy gene transcription remains unclear. Here, we identify Jumonji-D3 (JMJD3/KDM6B) histone demethylase as a key epigenetic activator of hepatic autophagy. Upon fasting-induced fibroblast growth factor-21 (FGF21) signaling, JMJD3 epigenetically upregulated global autophagy-network genes, including Tfeb, Atg7, Atgl, and Fgf21, through demethylation of histone H3K27-me3, resulting in autophagy-mediated lipid degradation. Mechanistically, phosphorylation of JMJD3 at Thr-1044 by FGF21 signal-activated PKA increased its nuclear localization and interaction with the nuclear receptor PPARto transcriptionally activate autophagy. Chronic administration of FGF21 in obese mice improved defective autophagy and hepatosteatosis in a JMJD3-dependent manner. Remarkably, in non-alcoholic fatty liver disease patients, hepatic expression of JMJD3, ATG7, LC3, and KL were substantially decreased. These findings demonstrate that FGF21-JMJD3 signaling epigenetically links nutrient deprivation with hepatic autophagy and lipid degradation in mammals

The dataset to discover ESCC related proteins

Project description:To discover ESCC related proteins, we used SWATH to quantify the protein abundance between ESCC and adjacent tissues. Briefly, we pooled 10 ESCCtissues and their corresponding adjacent tissues for SWATH acquisition with three replicates.Three DDA repeats were also acquired with the pooled 10-paired ESCC tissue.The trypsin digested peptide mixture was analyzed by AB SCIEX 5600 (AB SCIEX).The database searching procedure was achieved using ProteinPilot v4.5 (AB Sciex). The database is IPI_homo_sapiens_V3.87.
