Effects of gene scilencing of USP2 on expression profiles of HL60 cells

ABSTRACT: So far, we have found PMA induced USP2b isoform in myeloid leukemia cell lines such as HL60, THP-1, and U937. To explore molecular function of USP2 in the cells, we assess expression profiles of HL60-derivatives continuously expressing shRNA for USP2 and control shRNA.

Effects of gene scilencing of USP2 on expression profiles of HL60 cells

Project description:So far, we have found PMA induced USP2b isoform in myeloid leukemia cell lines such as HL60, THP-1, and U937. To explore molecular function of USP2 in the cells, we assess expression profiles of HL60-derivatives continuously expressing shRNA for USP2 and control shRNA. HL60 derivatives continuously expressing shRNA for USP2 and control shRNA were treated with PMA (30nM) for 0, 1, 2, and 3 days. Total RNA was extracted from the cells and subjected to microarray experiments using Human Genome U133 GeneChips.

Effects of gene scilencing of USP2 on expression profiles of HL60 cells (PMA 1day and LPS 4hrs)

Project description:So far, we have found phorbol 12-myristate 13-acetate (PMA) induced ubiquitin specific peptidase (USP) 2b isoform in myeloid leukemia cell lines such as HL60, THP-1, and U937. HL60, THP-1, and U937 undergoes differentiation into macrophage-like cells after stimulation with phorbol ester. To explore molecular function of USP2 in macrophages especially during lipopolysaccharide(LPS) response, we assess expression profiles of HL60-derivatives continuously expressing shRNA for USP2 and control shRNA.

Effects of PMA on exon usage of HL60, THP-1, and U937 cells

Project description:Myeloid leukemia cell lines HL60, THP-1, and U937 undergo macrophage-like differentiation after treatment with phorbol ester. To explore genes whose exon usage was altered during macrophage differentiation, we compared exome of PMA-treated (differentated) and vehicle-treated (undifferentiated) myeloid cell lines. HL60, THP-1, and U937 cells were treated with either phorbol 12-myristate 13-acetate (PMA,30nM) or its vehicle (DMSO) for 3 days, and subjected to exome analysis using Affymetrix human exon 1.0ST arrays.

Effects of supernatants of USP2 knockdown HL-60 cells and mock transfected HL60 cells on differentiated 3T3-L1 cells

Project description:Ubiquitin specifc protease (USP) 2 modulates various cellular responces including carcinogenesis, spermatogenesis, and glucose metabolism. So far, we established USP2 knockdown HL-60 cells to explore roles of USP2 in macrophages. In this experiment, we investigated whether USP2 knockdown HL-60 cells more prominently modulate function of adipocytes compared with control cells. USP2 knock down(KD) HL-60 cells and mock vector-transfected mock control cells were differentiated into macrophage-like cells in the presence of 30nM of phorbol 12-myristate 13-acetate for 5 days. Subseqently, supernatants of the USP2 KD cells and control cells were added to differentiated 3T3-L1 cells for 3 and 6 hrs. Total RNA was isolated from the supernatant-treated 3T3-L1 cells, and subjected to microarray analysis. Duplicate samples were prepared for each cell and time point.

Transcriptome analysis on whole kidney of Usp2 knockout mice

Project description:Ubiquitylation plays an important role in the control of Na+ homeostasis by the kidney. It is well established that the epithelial Na+ channel ENaC is regulated by the ubiquitin-protein ligase NEDD4-2, limiting ENaC cell surface expression and activity. Ubiquitylation can be reversed by the action of deubiquitylating enzymes (DUBs). One such DUB, USP2-45, was identified previously as an aldosterone-induced protein in the kidney, and is also a circadian output gene. In heterologous expression systems USP2-45 binds to ENaC, deubiquitylates it and enhances channel density and activity at the cell surface. Because the role of USP2-45 in renal Na+ transport had not been studied in vivo, we investigated here the effect of Usp2 gene inactivation in this process. We demonstrate first that the USP2-45 protein has a rhythmic expression with a peak at ZT12. Usp2-KO mice did not show any differences to wild-type littermates with respect to the diurnal control of Na+ or K+ urinary excretion and plasma levels neither on standard diet, nor after acute and chronic changes to low and high Na+ diets, respectively. Moreover, they had similar aldosterone levels either at low or high Na+ diet. Blood pressure measurements using telemetry did not reveal variations as compared to control mice. Usp2-KO did neither display alternations in ENaC or Na+,Cl--cotransporter (NCC) expression, nor were there any changes in regulatory protein levels, as evidenced by immunoblotting and transcriptome analysis. We conclude that USP2-45 is not crucial for the regulation of Na+ balance or maintenance of blood pressure in vivo.
