Abstract
BACKGROUND Ulcerative colitis (UC) is an inflammatory intestinal disorder featured by mucosal injury. MicroRNAs (miRNAs) play a role in the pathogenesis underlying UC. OBJECTIVES This study was conducted to investigate the role of miR-29c-3p in a dextran sodium sulfate (DSS)-induced UC mouse model and provide targets for UC treatment. METHODS The UC mouse model was established by DSS induction. The expression levels of miR-29c-3p, lysine-specific demethylase 6B (KDM6B), zonula occludens-1 (ZO-1), Occludin, and lactate dehydrogenase A (LDHA) were detected by real-time quantitative polymerase chain reaction or Western blot assays. The mucosal injury was evaluated by disease activity index (DAI), colon length, Hematoxylin-Eosin staining, and fluorescein isothiocyanate-glucan permeability test. The binding between miR-29c-3p and KDM6B and the occupation of KDM6B or trimethylated H3 lysine 27 (H3K27me3) on the LDHA promoter were analyzed by the dual-luciferase and chromatin-immunoprecipitation assays. RESULTS miR-29c-3p was downregulated while KDM6B and LDHA were upregulated in DSS mice. miR-29c-3p overexpression reduced DAI and inflammatory cell infiltration while increasing colon length, intestinal permeability, and levels of ZO-1 and Occludin. miR-29c-3p inhibited KDM6B expression and increased H3K27me3 occupation on the LDHA promoter, thus inhibiting LDHA transcription. Overexpression of KDM6B or LDHA averted the protective role of miR-29c-3p upregulation in mucosal injury. CONCLUSION miR-29c-3p limited KDM6B expression and increased the H3K27me3 occupation on the LDHA promoter to enhance LDHA transcription, moderating mucosal injury and delaying UC progression.

Abstract
Curcumin (CUR) is a promising natural compound in ulcerative colitis (UC) treatment, but limited by its low oral bioavailability and poor targeting ability. Therefore, given the targeting action of lactoferrin (LF) by binding to the LF receptors of intestinal epithelial cells (IECs) and of folic acid (FA) by binding to the FA receptors of macrophages, we developed an oral dual-targeting nanosystem. Laminarin (LA)-coated, FA-modified LF nanoparticles (NPs) were used to encapsulate CUR (LA/FA/CUR-NPs) with a food-grade, enzyme-sensitive, and dual-targeting capacity. For the generated NPs, LF improved the loading efficiency of CUR (95.08 %). The LA layer could improve the upper gastrointestinal tract stability of the NPs while improve drug release around colon lesion through β-glucanase digestion. Based on the cellular uptake evaluation, FA/CUR-NPs were capable of specifically targeting colonic epithelial cells and macrophages through LF and FA ligands, respectively, to enhance the uptake efficiency. Moreover, based on the advantage of the dual-targeting strategy, oral administration of FA/CUR-NPs obviously reduced colitis symptoms by alleviating inflammation, accelerating colonic mucosal barrier repair and restoring the balance of the intestinal microbiota. This dual-targeted nanodesign corresponded to the multi-bioresponsibilities of CUR, thus offering a promising approach in UC treatment.

Abstract
Herein, a β-1,3-d-glucan based microcarrier, yeast cell wall microparticles (YPs), was used to develop a food-source-based nano-in-micro oral delivery system for ulcerative colitis (UC) treatment. Briefly, lactoferrin (Lf), which targets intestinal epithelial cells, was used to encapsulate emodin (EMO) to form nanoparticles (EMO-NPs), and then loaded into YPs with the natural macrophages targeting ability, forming a final formula with two outer-inner targeting layers (EMO-NYPs). These dual-targeting strategy could enhance the dual-effects of EMO in anti-inflammatory and mucosal repair effects respectively. As expected, cell uptake assessment confirmed that EMO-NPs and EMO-NYPs could target on the Lf and dection-1 receptors on the membranes of Caco-2 cells and macrophages, respectively. Importantly, EMO-NYPs showed the best anti-UC effects compared to EMO-NPs and free EMO, by inhibiting NF-κB pathway to anti-inflammation and promoting intestinal mucosa repair via MLCK/pMLC2 pathway. The results show that EMO-NYPs are a promising food-based oral delivery system in anti-UC.

Abstract
BACKGROUND/AIMS Esophageal mucosal damage often causes scar tissue, leading to refractory stricture. The aim of this study was to clarify the effect of hepatocyte growth factor (HGF) on esophageal mucosal repair and fibrosis leading to stricture in a rat model of esophageal ulcer. METHODS Esophageal ulcers were induced in rats by topical exposure of the lower esophageal serosa to acetic acid, followed by intraperitoneal administration of HGF (200 µg/day) using an osmotic pump for 7 days. The effect of HGF on esophageal mucosal injury was investigated macroscopically and microscopically. The effect of HGF on epithelial cell proliferation and the expression of genes closely associated with the development of fibrosis were also examined. RESULTS The administration of HGF for 7 days led to a significant reduction in the ulcerative area and enhanced the proliferation of esophageal epithelial cells. HGF treatment significantly decreased the fibrosis, and subsequently attenuated not only the foreshortening but also the narrowing of the esophagus. The expression levels of tissue inhibitor of metalloproteinase (TIMP)-1, -2, and matrix metalloproteinase (MMP)-2, -9 were significantly decreased among rats treated with HGF. CONCLUSION HGF facilitates the repair of esophageal mucosal injury and may also ameliorate the esophageal fibrosis, possibly through enhanced re-epithelization.

Abstract
The physiologic and pathologic cellular and molecular changes occurring with age in the human colon affect both the inflammatory process leading to mucosal injury and the regenerative capacity of the epithelium. On the one hand, age-related telomere shortening and inflamm-ageing may lead to the development of colonic inflammation, which results in epithelial damage. On the other hand, the altered migration and function of regenerative stem cells, the age-related methylation of mucosal healing-associated genes, together with the alterations of growth factor signaling with age, may be involved in delayed mucosal regeneration. The connections of these alterations to the process of ageing are not fully known. The understanding and custom-tailored modification of these mechanisms are of great clinical importance with regard to disease prevention and modern therapeutic strategies. Here, we aim to summarize the age-related microscopic and molecular changes of the human colon, as well as their role in altered mucosal healing.

Abstract
Gut-associated lymphoid tissue is supposed to play a central role in both the organization of colonic repair mechanisms and colorectal carcinogenesis. In inflammatory conditions, the number, diameter and density of isolated lymphoid follicles (ILFs) increases. They are not only involved in immune surveillance, but their presence is also indispensable in normal mucosal regeneration of the colon. In carcinogenesis, ILFs may play a dual role. On the one hand they may support tumor growth and the metastatic process by vascular endothelial growth factor receptor signaling and producing a specific cytokine and cellular milieu, but on the other hand their presence is sometimes associated with a better prognosis. The relation of ILFs to bone marrow derived stem cells, follicular dendritic cells, subepithelial myofibroblasts or crypt formation, which are all involved in mucosal repair and carcinogenesis, has not been directly studied. Data about the putative organizer role of ILFs is scattered in scientific literature.
