Disease relevance of MUC2

  • In contrast, high levels of MUC2 and MUC3 mucin mRNA and immunoreactive protein were found in specimens with intestinal metaplasia [1].
  • In addition, with the exception of prostate cancer, focal aberrant expression of MUC2 and MUC3 epitopes was frequently observed [2].
  • No difference in MUC2 and MUC5AC protein was found between mucinous and non-mucinous carcinomas [3].
  • Low levels of MUC2 mRNA were detected in non-mucinous adenocarcinomas (5/27) while a higher proportion of mucinous carcinomas (4/9) was positive [3].
  • Goblet cells expressing the MUC2 gene and columnar cells expressing the MUC3 gene were consistent with an intestinal phenotype, which was observed in 15 tumours (71%) including nine adenomas and six borderline tumours [4].
 

High impact information on MUC2

  • These antibodies reacted with the MUC2-derived peptide but not with MUC1- or MUC3-derived peptides [5].
  • Second-generation monoclonal antibodies to intestinal MUC2 peptide reactive with colon cancer [5].
  • RESULTS: In the 22 RVAs, we found an overexpression of MUC2 and an aberrant expression of MUC5AC [6].
  • In pancreas cancer tissues and cell lines, increased expression of MUC2, MUC4, and MUC5C is shown [7].
  • RESULTS: MUC1 is the major apomucin expressed in normal pancreas, whereas MUC2-MUC5 are weakly expressed or undetectable [7].
 

Chemical compound and disease context of MUC2

 

Biological context of MUC2

  • In contrast, MUC2 and MUC3 gene expression was primarily restricted to the intestinal tract [2].
  • In gastric tumours, especially those with the intestinal phenotype, MUC2 and MUC4 genes are upregulated, and gastric-type and intestinal-type mucins are coexpressed [13].
  • Rabbit antiserum against a synthetic peptide corresponding to a tandemly repeated amino acid sequence in the human intestinal mucin apoprotein MUC2 was used in immunoprecipitation to study the biosynthesis of MUC2 in the colon-carcinoma cell line LS 174T [14].
  • The 5'-region reveals high degree of sequence similarity with MUC2 and MUC5B and codes for 1336 amino acids organized into a signal peptide, four pro-von Willebrand factor-like D domains (D1, D2, D' and D3) and a short domain which connects to the central repetitive region [15].
  • In patients with clam enterocystoplasty there was evidence of increasing up-regulation of MUC2, 3, 4 and 5AC expression in the urothelium toward the anastomotic site [16].
 

Anatomical context of MUC2

 

Associations of MUC2 with chemical compounds

 

Regulatory relationships of MUC2

  • MUC1 is up-regulated and MUC2 is down-regulated in colorectalcarcinomas [24].
  • In contrast, MUC2 mRNA was expressed at only low levels and MUC3 was not detected in the pancreatic tumor cell lines [25].
  • However, the existence of this inhibitory JNK pathways suggests a mechanism whereby--in the absence of NF-kappaB activation--TNF-alpha production during inflammation in vivo could actually inhibit MUC2 production, giving rise to the defective mucosal protection which characterizes inflammatory bowel disease [26].
  • These results suggest that p53 directly activates the MUC2 gene in many cell types [11].
  • Expression of DCC did not modulate constitutive or induced expression of MUC2, nor did DCC induce a mature goblet cell phenotype [27].
 

Other interactions of MUC2

  • Addition of bile during either storage in UW solution or rewarming period induced increased steady-state MUC2, MUC3 and MUC5AC mRNA levels.(ABSTRACT TRUNCATED AT 250 WORDS)[28]
  • MUC2 and TFF3 were colocalised throughout the large and small bowel mucosa [29].
  • Interleukin-1beta induces MUC2 and MUC5AC synthesis through cyclooxygenase-2 in NCI-H292 cells [30].
  • The expression of MUC2 and CDX2 was restricted to the intestinal, mucinous, and signet-ring cell-type adenocarcinomas of duodenal papillary origin (9 of 11, 82%; 11 of 11, 100%, respectively) [31].
  • Neither cell type showed detectable expression of intestinal MUC2 or gastric MUC6 [32].
