Mucin 1 Oncoprotein Expression Is Suppressed by the miR-125b Oncomir

open access: yesGenes & Cancer, 2010
The MUC1 oncoprotein is overexpressed in most human breast cancers by mechanisms that are incompletely understood. The microRNA, miR-125b, is downregulated in breast cancer cells. The present studies demonstrate that the MUC1 3'UTR contains a site for binding of the miR-125b seed region.

Nitric oxide induces MUC5AC mucin in respiratory epithelial cells through PKC and ERK dependent pathways

open access: yesRespiratory Research, 2007
Background Nitric oxide (NO) is generally increased during inflammatory airway diseases. This increased NO stimulates the secretion of mucin from the goblet cell and submucosal glands but the mechanism is still unknown precisely.

Rhoifolin Alleviates Ulcerative Colitis by Targeting NMNAT1 and Activating SIRT1‐FOXO1 Signaling to Enhance ILC3s Effector Function

open access: yesAdvanced Science, EarlyView.
Rhoifolin directly targets NMNAT1, thereby activating nicotinamide salvage pathway and promoting intracellular NAD+ biosynthesis. Elevated NAD+ levels enhance SIRT1 activity, leading to FOXO1 deacetylation and nuclear translocation. Nuclear FOXO1 subsequently binds to the IL‐22 promoter, upregulating IL‐22 transcription and potentiating ILC3 effector ...

Leucine increases mucin 2 and occludin production in LS174T cells partially via PI3K-Akt-mTOR pathway

open access: yesAnimal Nutrition, 2016
Mucin 2 and occludin play a crucial role in preserving the intestinal mucosal integrity. However, the role for leucine mediating intestinal mucin 2 and occludin expression has little been investigated.

Senkyunolide I Inhibits mtDNA‐cGAS‐STING Signaling in Macrophages via Targeting VDAC1 Oligomerization to Attenuate Ulcerative Colitis

open access: yesAdvanced Science, EarlyView.
In macrophages, senkyunolide I (SEI) directly targets the K12 residue of VDAC1 to inhibit its stress‐induced oligomerization, a critical upstream event that effectively prevents mitochondrial DNA release and subsequent cGAS‐STING pathway activation.

Targeted disruption of the murine mucin gene 1 decreases susceptibility to cholesterol gallstone formation1

open access: yesJournal of Lipid Research, 2004
Gallbladder mucins play a critical role in the pathogenesis of cholesterol gallstones because of their ability to bind biliary lipids and accelerate cholesterol crystallization.

Intelligent Programmable Membrane Nanosponge for Early Virus Blocking

open access: yesAdvanced Science, EarlyView.
A smart programmable nanosponge (ACNPs) displays high‐density viral receptors on its membrane and encapsulates fusion inhibitors to capture virions at the infection source through competitive binding and blocks their entry through protease inhibition for ultra‐early cascade interception. This modular, mucus‐penetrating platform shifts antiviral defence

Mucin adsorbed by E. coli can affect neutrophil activation in vitro

open access: yesFEBS Open Bio, 2020
Bacteria colonizing human intestine adhere to the gut mucosa and avoid the innate immune system. We previously demonstrated that Escherichia coli isolates can adsorb mucin from a diluted solution in vitro.

Ultrasound‐Activated Nanoinhibitors Blocking the Chemo‐Immune Checkpoint to Overcome Chemotherapy‐Induced Immune Resistance

open access: yesAdvanced Science, EarlyView.
A sono‐responsive chemo‐immune checkpoint nanoinhibitor (Sono‐TT8) co‐delivering TPZ chemotherapy and siXkr8 simultaneously kills tumor cells and blocks PS externalization, reversing chemotherapy‐induced immunosuppression and enhancing antitumor immunity. ABSTRACT Breast cancer features an immunosuppressive tumor microenvironment following chemotherapy

Transmembrane Mucin-1 Facilitates Oral Microbial Colonization in Oral Cancer

open access: yesOral
Mucins are a family of heavily glycosylated proteins that form the main organic component of the oral mucosal barrier complex. Transmembrane mucin 1 (tMUC1) is anchored at the superficial epithelial surface to provide a protective function.
