Project description:Human hepatocytes, HepaRG cells and HCC HepG2 cells were treated with 50nM of Microcystin-LR and cylindrospermopsin (CYN) to observe changes in gene expression.
Project description:We analyzed the effect of knockdown of miR-214 compared to wild type on the expression of genes and pathways involved in prostate cancer cells.
Project description:We chronically exposed HepaRG (differentiated hepatic cells that retain primary human hepatocytes characteristics) and HepaG2 (liver hepatocarcinoma cells) liver cells to physiologically relevant concentrations of Cadmiun and PFOAs chemicals (10nM) to observed how these affect global gene expression in these cellular models.
Project description:We investigated how selective mutation in STK11 or KEAP1 alters the transcriptional profile of cancer cells, and how the transcriptional profile of co-mutant cells might uniquely affect cancer-related pathways including control of proliferative potential, metabolic homeostasis, and cell death. We performed bulk RNAseq on none, single or double mutation of these genes in single cell knockout clones (n=3 per group) from both H358 and H292 cell lines.
Project description:We found that the fungus, Debaryomyces hansenii (D. hansenii), is enriched in inflamed intestinal tissue from patients of Crohn's disease and its administration to mice impairs colonic wound healing in multiple models of colonic injury and repair. To understand the mechanism, we isolated bone marrow derived macrophages from mice and stimulated them in vitro with a pure isolate of D. hansenii. Total RNA was isolated at multiple time points and assayed for transcriptomic analysis.
Project description:In this experiment, SUM149 IBC cells were cultured using baseline medium (N=3), and in baseline medium supplemented with increasing concentration of Lapatinib to induce resistance (N=3; rSUM149). Resistant reversal SUM149 cells (rrSUM149) were then generated by culturing in rSUM149 cells in baseline medium. Gene expression data were generated to identify differentially expressed genes, as well as differentially activated proteins and pathways during Lapatinib resistance and resistance reversal. Gene expression were also integrated with proteome expression data generated under the same conditions.
Project description:In this study, blood was collected from human participants with osteoarthritis pain, along with radiographic scores (Kellgren & Lawrence Score (KL)) and pain scores (Numerical Rating Scale (NRS)). Peripheral blood mononuclear cells were isolated from whole blood, and classical and intermediate monocytes were further isolated using fluorescence-activated cell sorting. mRNA was then extracted from monocytes for sequencing.
Project description:Genomic alterations that activate Fibroblast Growth Factor Receptor 2 (FGFR2) are common in intrahepatic cholangiocarcinoma (ICC), a deadly bile duct malignancy. FGFR kinase inhibitors (FGFRi) have shown promising efficacy against FGFR2+ ICC in clinical trials, leading to the regulatory approval of the ATP-competitive FGFR inhibitors, pemigatinib and infigratinib (BGJ398), for this subset of patients who failed standard treatment . However, the objective response rate (ORR) for each FGFR inhibitor (FGFRi) studied to date in FGFR2+ ICC is <45% and disease progression invariably arises within ~6-12 months. By employing high-throughput drug screens and signaling studies, we identified signaling feedback via the EGFR pathway as a major mediator of adaptive resistance to FGFR kinase inhibition in a set of patient-derived ICC models. To further gain insights into the synergistic effects of the EGFR/FGFR combination and address the mechanisms underlying the survival pathway reactivation, we performed RNA sequencing in our FGFR-driven ICC models (ICC21 and ICC10-6). For these studies, we treated FGFR2 fusion+ ICC cell lines ICC21/ICC10-6 with four conditions (DMSO/Infigratinib/Afatinib/Combo) for 4 hours followed by RNA sequencing.
Project description:The miR-99 family is one of the evolutionarily most ancient microRNA families, and it plays a critical role in development. There are 3 members of the miR-99 family in humans (miR-99a, miR-99b, miR-100). Recent studies suggested that miR-99 family also regulates various physiological processes in adult tissues, such as wound healing, and a number of diseases processes, including cancer. Here, we aim to identify gene expression changes mediated by miR-99 family in epithelial cells. HaCaT cells and 1386Ln cells were transfected with miR-100 mimic or with negative control mimic (Dharmacon), the total RNA was isolated using miRNeasy Mini kit (Qiagen), and labeled and hydridized to the Affymetrix GeneChip Human Gene 1.0 ST arrays according standard protocol.
