    Using Human Induced Pluripotent Stem Cell Derived Organoids to Identify New Pathologies in Patients with PDX1 Mutations

    Gastric fundic, antral, and duodenal organoids were generated using induced pluripotent stem cell (iPSC) lines from a PDX1188delC/188delC patient and an isogenic iPSC line where the PDX1 point mutation was corrected.

    Gastric Stem Cells Promote Inflammation and Gland Remodeling in Response to Helicobacter pylori via Rspo3-Lgr4 Axis

    Scientists identified that Lgr4 regulated Lgr5 expression and was required for H. pylori-induced hyperplasia and inflammation, while Lgr5 alone was not.

    PU.1-Driven Th9 Cells Promote Colorectal Cancer in Experimental Colitis Models through IL-6 Effects in Intestinal Epithelial Cells

    Colorectal cancer patient samples and samples from AOM/DSS treated mice were analyzed for expression of IL-9, CD3 and PU.1 by FACS analysis and immunohistochemistry.

    Abstract

    Garcinone C Suppresses Tumorsphere Formation and Invasiveness by Hedgehog/Gli1 Signaling in Colorectal Cancer Stem-Like Cells

    Researchers investigated the effect of garcinone C on cancer stemness and invasiveness in colorectal cancer; Gli1 was noted as pivotal in maintaining stemness and invasiveness in HCT116 and HT29 cancer stem cells.

    CHREBP Suppresses Gastric Cancer Progression via the Cyclin D1-RB-E2F1 Pathway

    Investigators found carbohydrate response element binding protein (CHREBP) downregulation in gastric cancer (GC) tissues, and CHREBP was determined to be an independent diagnostic marker of GC.

    HOTAIR/miR-1277-5p/ZEB1 Axis Mediates Hypoxia-Induced Oxaliplatin Resistance via Regulating Epithelial-Mesenchymal Transition in Colorectal Cancer

    Scientists discovered that hypoxia-induced oxaliplatin resistance and HOX transcript antisense RNA (HOTAIR) expression was increased in hypoxia-treated colorectal cancer (CRC) cell lines and CRC tumors.

    Neogambogic Acid Suppresses Characteristics and Growth of Colorectal Cancer Stem Cells by Inhibition of DLK1 and Wnt/β-Catenin Pathway

    SW480 and HCT116 cells were treated with neogambogic acid at different concentrations and transfected with siDLK1 and pcDNA3.1-DLK1 plasmids.

    Abstract

    Mex3a Marks Drug-Tolerant Persister Colorectal Cancer Cells That Mediate Relapse after Chemotherapy

    Patient-derived organoids expand from highly proliferative LGR5+ tumor cells; however, investigators discovered that the lack of optimal growth conditions specified a latent LGR5+ cell state.
