    Phosphorylation of PPDPF via IL6-JAK2 Activates the Wnt/β-Catenin Pathway in Colorectal Cancer

    Pancreatic progenitor cell differentiation and proliferation factor (PPDPF) was found to be upregulated in colorectal cancer and significantly correlated with tumor-node-metastasis stages and survival time.

    Downregulation of miR-182-5p by NFIB Promotes NAD+ Salvage Synthesis in Colorectal Cancer by Targeting NAMPT

    Investigators showed that nuclear factor I B (NFIB) promoted colorectal cancer (CRC) proliferation in vitro and growth in vivo, and down-regulation of NFIB can reduce the level of nicotinamide adenine dinucleotide.

    CD44 Mediated Colon Cancer Targeting Mutlifaceted Lignin Nanoparticles: Synthesis, In Vitro Characterization and In Vivo Efficacy Studies

    Cell anti-proliferation and mitochondrial depolarization studies on HT-29 cells suggest significantly improved chemotherapeutic efficacy of hyaluronic acid-coated irinotecan-loaded lignin nanoparticles. In vitro studies showed that nanoparticles have retained the antioxidant activity of lignin that can prevent cancer relapse.

    Diet Effects on Colonic Health Influence the Efficacy of Bin1 mAb Immunotherapy for Ulcerative Colitis

    Researchers found that standard or high fiber diets in mice positively influenced their colonic health, whereas a high fat-high protein diet negatively influenced colonic health, consistent with clinical findings.

    Integrin α7β1 Represses Intestinal Absorptive Cell Differentiation

    The effects of knocking down ITGA7 in Caco-2/15 cells were studied using shRNA and CRISPR/Cas9 strategies. Abolition of the α7 integrin subunit resulted in a significant increase in the level of differentiation and polarization markers as well as the morphological features of intestinal cells.
