The role of subclonal population of cells on tumor growth

ABSTRACT: In this study we activated subclonal differentiation in pancreatic adenocarcinoma cells to study the role of differentiated cells on tumor growth. Mesenchymal pancreatic adenocarcinoma (MiaPaCa) cells differentiated into adipose and endothelial cells to assess the tumor initiation potential of the differentiated cells and molecular changes associated with cell differentiation. Epithelial (TC-2742-2) cells expressed with Ebf2 were analyzed for its tumorigenic potential and molecular changes associated with Ebf2 expression.

Hypoxia TMT Proteomics on Pancreatic Cancer Cell Lines

Project description:PDAC(pancreatic ductal adenocarcinoma) cell lines- MiaPaca and 8988T were exposed to normoxic (20% Oxygen, 2 replicates each for MiaPaca and 8988T) or Hypoxia (0.1% Oxygen,3 replicates each for MiaPaca and 8998T) for 24 hrs

Translational control of mTOR/4E-BP1 axis in MiaPaca-2 cells

Project description:Pancreatic ductal adenocarcinoma (PDAC) relies on hyper-activated protein synthesis. Consistently, human and mouse PDAC lose expression of the translational repressor and mTOR target 4E-BP1. Using genome-wide polysome-profiling, we here explore mRNAs whose translational efficiencies depend on the mTOR/4E-BP1 axis in Miapaca-2 cells. This was performed by isolating cytoplasmic and efficiently translated (heavy polysome-associated) mRNAs from MiaPaca-2 cells upon PP242-mediated mTOR inhibition

RNA-Sequencing for pancreatic cancer cells with scramble-shRNA and GPx1-shRNA

Project description:We reported glutathione peroxidase-1 (GPx1) was negatively associated with overall survival in pancreatic ductal adenocarcinoma patients. Silencing GPx1 in pancreatic cancer cells showed epithelial–mesenchymal transition phenotype and increased chemoresistance to gemcitabine in vitro and in vivo. Next, to search for a putative molecular mechanism, we used a high-throughput gene expression profiling array in scramble-shRNA and GPx1-shRNA pancreatic cancer cells (MiaPaCa-2). This study provides the differentially expressed genes and altered signaling pathways towards characterization of gemcitabine resistance cell populations.

Project description:Cell conditioned medium from human pancreatic cancer cell lines MiaPaCa-2, AsPC-1, primary pancreatic cell lines as well as human FFPE tissue samples from pancreatic ductal adenocarcinoma (PDAC), chronic pancreatitis (CP), ampullary cancer, non-malignant adjacent pancreas and normal pancreas were analyzed via targeted (SRM, PRM) and/or explorative (DIA) mass spectrometry.

Ebf2 is a selective marker of brown and beige adipogenic precursor cells (Microarray)

Project description:Brown adipocytes, muscle and dorsal dermis descend from precursor cells in the dermomyotome, but the factors that regulate commitment to the brown adipose lineage are unknown. Here, we prospectively isolated and determined the molecular profile of embryonic brown preadipose cells. Brown adipogenic precursor activity in embryos was confined to PdgfrÎ±+, Myf5Cre-lineage-marked cells. RNAseq analysis identified Early B Cell Factor-2 (Ebf2) as one of the most selectively expressed genes in this cell fraction. Importantly, Ebf2-expressing cells purified from Ebf2-GFP embryos or brown fat tissue did not express myoblast or dermal cell markers and uniformly differentiated into brown adipocytes. Interestingly, Ebf2-expressing cells from white fat tissue in adult animals differentiated into brown-like (or beige) adipocytes. Loss of Ebf2 in brown preadipose cells reduced the expression levels of brown preadipose-signature genes, whereas ectopic Ebf2-expression in myoblasts activated brown preadipose-specific genes. Altogether, these results indicate that Ebf2 specifically marks and regulates the molecular profile of brown preadipose cells. Embryonic fibroblasts, isolated from dorsal body wall of E14.5 Ebf2(GFP)/+ embryos, were further fractionated based on the expression of PDGFRÎ± and Ebf2 (GFP). Affymetrix microarray analysis was prefromed,to compare the gene expression between PDGFRÎ±+ Ebf2(GFP)- and PDGFRÎ±+ Ebf2(GFP)+ cells.

Expression data of MIAPaCa-2 cells transfected with NDRG1

Project description:NDRG1 functions as a metastasis suppressor in pancreatic and other cancers. To determine the molecular function of NDRG1 in MIAPaCa-2 pancreatic cancer cells, we performed a whole genome gene array analysis on these cells stably transfected with NDRG1 when compared to empty vector-transfected controls. The differentially expressed genes indetified in this microarray may represent potential molecular targets of NDRG1 in pancreatic cancer. Two separate RNA extracts of MIAPaCa-2 vector control and NDRG1 transfected cells were collected and hybridised to Affymetrix Human Genome U133 Plus 2.0 chips.

Secretome analysis of Pancreatic Cancer Spheroid with myeloid cell infiltration

Project description:Pancreatic ductal adenocarcinoma (PDAC) is one of the most hypoxic, lethal, and treatment resistant cancers. Due to its desmoplastic and hypoxic nature along with the abundance of myeloid cell infiltration and scare T cell infiltration, PDAC is considered a cold tumor. Using MiaPaCA-2 as a PDAC spheroid model with hypoxic core grown in serum-free defined media and immune cell infiltration, we assessed the modulation of PDAC secretome and characterized immunomodulatory factors secreted.
