The novel lysine deacetylase ABHD14B regulates transcription of metabolic genes

ABSTRACT: Purpose: To understand the role of ABHD14B in cellular metabolism by regulation of transcription. To address this, we performed a RNA-seq experiment with stable knockdowns of ABHD14B in HEK293T cells generated by lentivirus-based shRNA technology. Methods: Four biological replicates of HEK293T wild-type control, non-targeting shRNA control (NT), and two knockdowns (KD_2 and KD_3) of ABHD14B cells were collected and total RNA was extracted in QIAzol. The total RNA was used to generate a cDNA library using Quantseq 3' mRNA kit Fwd. Results: Transcriptional profiling revealed that genes involved in cellular metabolism are differentially regulated in HEK293T ABHD14B knockdown cells. Conclusions: Our study demonstrates the first extensive transcriptomics analysis of mammalian cells upon knocking down ABHD14B, and finds that loss of ABHD14B results in altered expression of glucose and lipid metabolic genes. This observation was complemented by changes in the levels of key intermediates of glucose metabolic pathways and triglycerides. Together, our findings illuminate an important metabolic role played by the KDAC ABHD14B.

mRNA expression profiling in MDA-MB-231 (LM1) cells with a tet-incible MBD2 or p66α knock down, or treated with MBD2-targeting small molecule ABA or APC

Project description:The goal of this study is to compare mRNA expression profiles among wild type, MBD2 knock down, p66α knock down, and ABA- and APC-treated cells.. All cell lines were maintained in DMEM supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin. For the doxycycline inducible gene expression regulation, each cell lines were incubated in the presence of 1 μg/ml doxycycline for 2 days. For the drug treatment, MDA-MB-231 (LM1) cells were incubated in the presence of 10 μM ABA or APC for 2 days. Total cellular RNAs were extracted using Qiazol reagent. The RNA quality was examined by spectrophotometry, agarose gel electrophoresis (calculating the 18S and 28S rRNA ratio) and an Agilent Technologies 2100 Bioanalyzer (ensuring a RIN value greater than 7). Library was prepared with QuantSeq 3’ mRNA-Seq Library Prep Kit FWD. The constructed libraries were subjected to 75-bp single-end sequencing using an Illumina NextSeq 500 sequencer. Using an optimized data analysis workflow, we mapped to the human genome (build hg19) and identified 25,737 transcripts in these cell lines.

RNA sequencing of young versus aged endothelial cells

Project description:Freshly dissected Thymus, Kidney, and Spleen from young and aged mice were subjected to collagenase digestion to prepare single-cell suspension for the isolation of endothelial cells. Endothelial cells form the single-cell suspension was isolated using a magnetic bead-based separation method using CD144 and Endomucin antibody. RNA from 150,000 cells from each group was isolated using the RNeasy Plus Micro Kit (QIAGEN) according to the manufacturer’s instructions. The library preparation was performed using QuantSeq 3’ mRNA-Seq Library Prep Kit FWD for Illumina.

QUANTSEQ 3' sequencing of protrusions and cell bodies of control (NT) or LARP6 siRNA (LARP6 KD) transfected MDA-MB231 breast cancer cells

Project description:To assess how LARP6 affects mRNA localisation to cell-protrusions, we transfected MDA-MB231 cells with either non-targeting control siRNA or LARP6 siRNA for 72 hrs, before fractionating the cells into protrusion and cell-bodies, and analysed total RNA from each fraction via Lexogen QUANTSEQ FWD 3' mRNA sequencing. Protrusion induction was done for 2 hrs on 3 micron transwell filters (Corning). The experiment was performed twice using two independent batches of cells, and sequencing was carried out on an Illumina NextSeq 500 sequencer.

Transcription factor network analysis identifies REST/NRSF as an intrinsic regulator of CNS regeneration

Project description:The goal of this study is to use RNA-seq to investigate the molecular mechanisms by which REST inhibition regulates corticalspinal axon regeneration. To achieve this goal, cortical motor neurons from adult wild-type (WT) and REST conditional knockout (cKO) were purified at 1, 3, 7 days following spinal cord injury (SCI) or sham operation. RNA-seq libraries for cortical motor neurons were prepared with the QuantSeq mRNA-Seq library prep kit FWD for Illumina (Lexogen) and sequenced using HiSeq4000 (Illumina). Sequenced reads were mapped to reference genome (mm10) using STAR, and count level data were quantifed using Salmon. Differential gene expression analysis was performed using limma voom.

SPANX control of Lamin A/C modulates nuclear architecture and promotes melanoma growth

Project description:Purpose: To investigate mechanisms underlying SPANX knockdown phenotypes, we monitored changes in gene expression profiles in A375 melanoma cells subjected to SPANX KD (RNA-Seq). Methods: RNASeq Libraries were prepared from isolated total RNA using the QuantSeq 3' mRNA-Seq Library Prep Kit FWD for Illumina from Lexogen, (Vienna, Austria). Barcoded libraries were pooled and single end sequenced (1X75) on the Illumina NextSeq 500 using the High output V2.5 kit (Illumina Inc., San Diego CA). Raw data FASTQ files were generated by standstard illumina base calling pipeline and stored in illumina cloud service BaseSpace. Reads were aligned with the STASR aligner. Analyses of differentially expressed genes (DEGs) were subsequently performed using a negative binomial test method (edgeR)10 implemented using SARTools R Package Results: Of 609 genes deregulated by both shRNA, 454 were upregulated and 123 were downregulated. Networks associated with cell division were downregulated following SPANX KD, while those associated with 3-phosphoinositide biosynthesis were upregulated. Notably, IPA analysis identified the cell cycle as the primary pathway deregulated, and further analysis using the reactome database revealed that most of those genes were associated with the G1/S transition.
