Ubiquitin-modified proteome analysis of wildtype and UFD1s-deficient HEK293T cells

ABSTRACT: To order to determine cellular ubiquitination levels, wildtype (WT) and UFD1s-deficent (MUT) cells were treated with 25 μM MG132 for 6 h. Cells were then lysed in UA buffer (8 M Urea, 100 mM Tris-HCl pH 8.5) on ice for 10 min. Cells were harvested, frozen in liquid nitrogen and stored at -80 ℃ for further ubiquitin (label-free)-modified proteome.

Comparative analysis of Tet2 catalytic deficient and knockout bone marrow over time

Project description:In this study, we investigated the role of Tet2 in regulation of hematopoietic genes by performing transcriptomic analysis of Tet2 WT, Mut, and KO LSK and Lin– cells at 3, 6, 9, and 12 months by RNA-seq, and mapping the DNA methylation landscape of 3-month-old Tet2 WT, Mut, and KO LSK and Lin– cells. (1) We find that loss of Tet2 (Tet2 KO) vs. a loss of Tet2 catalytic function (Tet2 Mut) at different time points and cell types causes distinct gene expression changes when compared to WT samples as assessed by RNA-seq. (2) Additionally, we find that many genes implicated in lymphoma and leukemia are deregulated in Tet2 Mut and KO LSK and Lin– cells, consistent with the phenotypes observed in mice transplanted with Tet2 Mut and KO bone marrow. (3) We also mapped genome-wide DNA methylation levels of WT, Tet2 Mut, and KO LSK and Lin– cells at 3 months by WGBS and establish a role for Tet2 in demethylating genes implicated in lymphoma and leukemia initiation and progression.

Catalytic dependent and independent roles of Tet3 in activation of ectodermal and silencing of mesodermal programs during neuroectoderm specification

Project description:In this study: (1) we distinguished Tet3 target genes that are regulated by its catalytic vs. noncatalytic functions in neuroectoderm (NE) cells by transcriptomic profiling of Tet3 wildtype (WT), Tet3 catalytic mutant (Mut), and Tet3 knockout (KO) NE cells by RNA-seq. (2) We mapped genome-wide DNA methylation of Tet3-WT, Tet3-Mut, and Tet3-KO NE cells by WGBS. (3) We determined Tet3 genome-wide occupancy in Tet3-WT NE cells by CUT&Tag. (4) We mapped 5hmC rich regions in Tet3-WT, Tet3-Mut, and Tet3-KO NE cells by hmeDIP. (5) We overexpressed (OE) the Tet3 target gene Dnmt1 (D) or an empty vector (EV) in Tet3-WT, Tet3-Mut, and Tet3-KO NE cells and assessed gene expression by RNA-seq. (6) We overexpressed (OE) Tet3 (T) or an empty vector (EV) in Tet3-WT, Tet3-Mut, and Tet3-KO NE cells and examined gene expression changes in these cells by RNA-seq.

Ubiquitin remnant motif profiling (Ubiquitomics) in VACV infected HeLa cells

Project description:HeLa cells were pretreated with MG132, inoculated with VACV-Cop at an MOI of 3 for 1 h, and posttreated with MG132 again. Cells were lysed and extracted proteins were digested to peptides using trypsin, and desalted peptides were subjected to automated diGly enrichment using the PTMScan ubiquitin remnant motif kit (Cell signaling) according to manufactuer's instructions.

Systemic Comparison of Heat Shock Response Induced by Heat Shock and a Proteasome Inhibitor in Mouse Fibrosarcoma Cells and Their Thermotolerant Counterparts

Project description:Heat shock response (HSR) is a cellular defense mechanism against various stresses. Both heat shock and proteasome inhibitor MG132 cause the induction of heat shock proteins, a distinct feature of HSR. To better understand the molecular basis of HSR, we subjected the mouse fibrosarcoma cell line, RIF-1, and its thermotolerant variant, TR-RIF-1 cells, to heat shock and MG132. We compared mRNA expressions using microarray analysis during recovery after heat shock and MG132 treatment. This study led us to group the 3,245 up-regulated genes by heat shock and MG132 into three families: genes regulated 1) by both heat shock and MG132 (e.g. chaperones); 2) by heat shock (e.g. DNA-binding proteins including histones); and 3) by MG132 (e.g. innate immunity and defense-related molecules). RIF-1 and TR cells were heat shock treated or MG132 treated and harvested after various times of recovery. mRNA expressions were compared to untreated samples. Biological replication was done.

Natural compounds ursolic acid and digoxin exhibit inhibitory activities to cancer cells in RORγ-dependent and -independent manner

Project description:Natural compounds ursolic acid (UA) and digoxin isolated from fruits and other plants display potent anti-cancer effects in preclinical studies. UA and digoxin have been at clinical trials for treatment of different cancers including prostate cancer, pancreatic cancer and breast cancer. However, they displayed limited benefit to patients. Currently, a poor understanding of their direct targets and mechanisms of action (MOA) severely hinders their further development. We previously identified nuclear receptor RORγ as a novel therapeutic target for castration-resistant prostate cancer (CRPC) and triple-negative breast cancer (TNBC) and demonstrated that tumor cell RORγ directly activates gene programs such as androgen receptor (AR) signaling and cholesterol metabolism. Previous studies also demonstrated that UA and digoxin are potential RORγt antagonists in modulating the functions of immune cells such as Th17 cells. Here we showed that UA displays a strong activity in inhibition of RORγ-dependent transactivation function in cancer cells, while digoxin exhibits no effect at clinically relevant concentrations. In prostate cancer cells, UA down-regulates RORγ-stimulated AR expression and AR signaling, whereas digoxin up-regulates AR signaling pathway. In TNBC cells, UA but not digoxin alters RORγ-controlled gene programs of cell proliferation, apoptosis and cholesterol-biosynthesis.Together, our study reveals for the first-time that UA, but not digoxin, acts as a natural antagonist of RORγ in the cancer cells. Our finding that RORγ is a direct target of UA in cancer cells will help select patients with tumors that likely respond to UA treatment.
