    Carbon Nanotubes Promote the Development of Intestinal Organoids through Regulating Extracellular Matrix Viscoelasticity and Intracellular Energy Metabolism

    The authors investigated the profitable effect of carbon nanotubes (CNTs) with a different graphene layer and surface modification on the 3D model of intestinal organoids and demonstrated that CNTs promoted the development of intestinal organoids over time.

    RANBP1 Promotes Colorectal Cancer Progression by Regulating Pre-miRNA Nuclear Export via a Positive Feedback Loop with YAP

    Investigators observed high expression of RAN binding protein 1 (RANBP1) in colorectal cancer (CRC) tissues. In vitro and in vivo functional experiments demonstrated that RANBP1 promoted the proliferation and invasion of CRC cells and inhibited the apoptosis of CRC cells.

    Abstract

    CRISPR Screens Identify Cholesterol Biosynthesis as a Therapeutic Target on Stemness and Drug Resistance of Colon Cancer

    To identify genetic vulnerabilities of colon cancer, investigators performed targeted CRISPR dropout screens comprising 657 Drugbank targets and 317 epigenetic regulators on two patient-derived colon cancer stem cells-enriched spheroids.

    ECHS1, an Interacting Protein of LASP1, Induces Sphingolipid-Metabolism Imbalance to Promote Colorectal Cancer Progression by Regulating Ceramide Glycosylation

    Through an LC–MS assay, LIM and SH3 protein 1 (LASP1) was identified as a sphingolipid-metabolism-involved protein, and short-chain enoyl-CoA hydratase (ECHS1) was identified as a new LASP1-interacting protein through a protein assay in colorectal cancer.

    AHA1 Regulates Cell Migration and Invasion via the EMT Pathway in Colorectal Adenocarcinomas

    To investigate how AHA1 expression regulated the cancer cell progression and/or metastasis of human colorectal cancer (CRC), the expression levels of AHA1 and Hsp90 were examined in 105 CRC tissue samples and compared with those in paired normal tissue.
