    Abstract

    Nanoparticle-Induced Chemoresistance: The Emerging Modulatory Effects of Engineered Nanomaterials on Human Intestinal Cancer Cell Redox Metabolic Adaptation

    Investigators screened several representative food-borne comparator engineered nanomaterials and reported that human colon cancer cells could insidiously exploit ZnO nanoparticle-induced adaptive response to acquire resistance against several chemotherapeutic drugs.

    Intestinal Brush Border Formation Requires a TMIGD1-Based Intermicrovillar Adhesion Complex

    Scientists identified a second adhesion complex localized at the proximal base region of microvilli. This complex contained the immunoglobulin superfamily member TMIGD1, which directly interacted with the microvillar scaffolding proteins EBP50 and E3KARP.

    PLGA-Microspheres-Carried circGMCL1 Protects Against Crohn’s Colitis Through Alleviating NLRP3 Inflammasome-Induced Pyroptosis by Promoting Autophagy

    CircRNA microarray and quantitative real time-polymerase chain reaction analyses were performed to investigate and verify the candidate dysregulated circRNA.

    Circular RNA circPGD Contributes to Gastric Cancer Progression via the Sponging miR-16-5p/ABL2 Axis and Encodes a Novel Pgd-219aa Protein

    Functionally, circPGD promoted cell proliferation, migration, and suppressed apoptosis in vitro. Mechanistically, circPGD sponged miR-16-5p for relieving miR-16-5p suppression on the corresponding target ABL2 via the SMAD2/3 and YAP signaling pathways.

    Intra-Tumor Heterogeneity of Cancer Stem Cell-Related Genes and Their Potential Regulatory microRNAs in Metastasizing Colorectal Carcinoma

    The authors provide evidence that the expression of cancer stem cell‑related genes and their potential regulatory miRNAs contribute to intra‑tumor heterogeneity in colorectal carcinoma, lymph node, and liver metastasis.

    Abstract

    NudCD1 as a Prognostic Marker in Colorectal Cancer and Its Role in the Upregulation of Cellular Spindle Assembly Checkpoint Genes and LIS1 Pathways

    Scientists investigated the role of NudCD1 in spindle assembly checkpoint regulation and in the prognosis of colorectal cancer.

    Hypoxia-Inducible Factors, mTOR, and Astrin Constitute an Integrative Regulatory Network in Colon Cancer Cells

    Since mTOR, Astrin, and hypoxia-inducible factors are involved in promoting the growth and survival of cancer cells, researchers investigated the possible interaction between them in cultured colon cancer cells.

    The Role of Goblet Cells and Mucus in Intestinal Homeostasis

    The authors present an overview of the current understanding of the role of goblet cells and the mucus layer in maintaining intestinal health during steady-state and how alterations to these systems contribute to inflammatory and infectious disease.
