Project description:The dolichyl-diphosphooligosaccharide-protein glycosyltransferase non-catalytic subunit (DDOST) is a key component of the oligosaccharyltransferase complex catalyzing N-linked glycosylation in the endoplasmic reticulum lumen. DDOST is associated with several cancers and congenital disorders of glycosylation. However, its role in pancreatic cancer remains elusive, despite its enriched pancreatic expression. Using quantitative mass spectrometry, we identify 30 differentially expressed proteins and phosphopeptides (DEPs) after DDOST knockdown in the pancreatic ductal adenocarcinoma (PDAC) cell line PA-TU-8988T. We evaluated DDOST / DEP protein-protein interaction networks using STRING database, correlation of mRNA levels in pancreatic cancer TCGA data, and biological processes annotated to DEPs in Gene Ontology database. The inferred DDOST regulated phenotypes were experimentally verified in two PDAC cell lines, PA-TU-8988T and BXPC-3. We found decreased proliferation and cell viability after DDOST knockdown, whereas ER-stress, ROS-formation and apoptosis were increased. In conclusion, our results support an oncogenic role of DDOST in PDAC by intercepting cell stress events and thereby reducing apoptosis. As such, DDOST might be a potential biomarker and therapeutic target for PDAC.

Project description:We report that m6A reader IGF2BP2 participates in the regulation of glutamine metabolism in AML. To further clarify whether IGF2BP2 knockdown (KD) leads to translational inhibition, we perform Ribo-seq in control and IGF2BP2 KD cells.

Project description:T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive malignant leukemia with extreme limited treatment for relapsed patients. N6‐methyladenosine (m6A) reader Insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2) participates in the initiation and growth of cancers by communicating with various targets. Here, we found IGF2BP2 is highly expressed in T-ALL. Gain and loss of IGF2BP2 demonstrated IGF2BP2 was essential for T-ALL cell proliferation in vitro and loss of IGF2BP2 prolonged animal survival in a human T-ALL xenograft model. Mechanistically, IGF2BP2 directly bound to T-ALL oncogene NOTCH1 via an m6A dependent manner. Furthermore, we identified a small-molecule IGF2BP2 inhibitor JX5 and treatment of T-ALL with JX5 showed similar functions as knockdown of IGF2BP2. These findings not only shed light on the role of IGF2BP2 in T-ALL, but also provide an alternative γ‑Secretase inhibitors (GSI) therapy to treat T-ALL.

Project description:Purpose: Due to its high metastatic proclivity, pancreatic ductal adenocarcinoma (PDAC) is one of the most deadly types of cancer. Therefore, it is imperative to better understand how the disease spreads as it progresses. Using a novel genetically engineered mouse model that allows us to isolate a subpopulation of cancer cells with superior metastatic capacity, we show that this aggressive phenotype correlates exclusively with a strong hypoxia signature. We subsequently identified the novel hypoxia-inducible gene Blimp1, which appears to play a critical role in regulating the hypoxic response upon its induction. Furthermore, genetic ablation of Blimp1 greatly reduces the level of metastasis in a PDAC mouse model. The nature of this Blimp1-regulated hypoxia signature is very unstable, since the seeded metastatic lesions mostly re-adopt similar transcriptomic profiles as the primary tumors. In conclusion, our results offer a potential mechanistic insight into how hypoxia drives metastasis in PDAC. Methods: The liver metastasis cell line 688M was subjected to control or knockdown of Blimp1 before assay. Cells ere validated for knockdown efficiency and then cultured under normoxia and hypoxia (0.5% O2) for 24 hours before preparation for ATAC-Seq (total of 4 groups with 2 technical replicates per group, overall 8 samples). Reference for ATACSeq: Buenrostro et al. 2013. Nat Methods 12:1213-8. Results: For the control knockdown group, 0.5% O2 culture (hypoxia) for 24 hours induced dramatic changes in global genome accessibility, and Blimp1 knockdown appeared to induce minimum changes in chromatin accessibility under hypoxia or normoxia (20% O2). Conclusions: Compared to our RNASeq profiles of the same liver met PDAC cell line under identical conditions, Blimp1 appeared to impact a global gene expression changes under hypoxia that is not associated with a corresponding changes of chromatin accessibility.

Project description:This microarray is an analysis of differentially expressed genes in three pancreatic ductal adenocarcinoma cell lines treated with LXR-agonist GW 3965. We first report that GW 3965 has antiproliferative effects in three PDAC cell lines. This microarray was designed to identify key mechanisms of the antiproliferative effect of LXR agonists within pancreatic cancer cell lines. Total RNA obtained from BxPC-3, MIA-PaCa-2, and PANC-1 pancreatic cancer cells grown in culture treated GW 3965 or ethanol (vehicle control) for 72 hours.
