In obstructive jaundice condition, goblet cells and MUC2 were reduced which were involved in the damage of intestinal mucosa barrier; biliary drainage increased goblet cells and MUC2, repaired mucosa layer and restored the intestinal mucosa barrier function.
Title: Internal biliary drainage superior to external biliary drainage in improving gut mucosa barrier because of goblet cells and mucin-2 up-regulation.
The data obtained may indicate involvement of genes Tlr2, Muc2, Defa in development of inflammation in the duodenum due to dysbiotic changes under conditions of prolonged hypochlorhydria.
Title: Expression of Tlr2, Defa, Muc2 genes in rat duodenal upon long-term gastric hypacidity and with multiprobiotic correction.
Rat Muc2 was expressed in fetal intestinal goblet cells of surface epithelium of villi and developing Lieberkuhn crypts. In neonates and adults, Muc2 was expressed at luminal goblet cells of small and large intestine and at gastric mucous and glandular cells. Muc5ac protein was observed in embryonic gastric and lung samples; expression increased during development and postnatal and adult life.
Title: Temporal and spatial expression of Muc2 and Muc5ac mucins during rat respiratory and digestive tracts development.
Data suggest that expression of Muc2 in mucosa of jejunum can be upregulated by dietary factors (here, apple pectins as dietary supplements).
Title: Low-methoxyl pectin stimulates small intestinal mucin secretion irrespective of goblet cell proliferation and is characterized by jejunum Muc2 upregulation in rats.
the repeated exposure to water immersion stress decreases Muc2 synthesis in the goblet cells via decreased Cdx2 expression
Title: Repeated exposure to water immersion stress reduces the Muc2 gene level in the rat colon via two distinct mechanisms.
These results indicate that mucin plays an important role in the preservation of the mucosal barrier and that ischemia but not digestive enzymes disturbs mucin integrity, while digestive enzymes actively mediate epithelial cell disruption.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
