摘要: The secreted, goblet cell-derived protein Clca1 (chloride channel regulator, calcium-activated-1) has been linked to diseases with mucus overproduction, including asthma and cystic fibrosis. In the intestine is found in an abundance expression pattern similar Muc2, major structural component. We hypothesized that required for synthesis, structure or barrier function of intestinal therefore compared wild type Clca1-deficient mice under naive at various time points DSS (dextran sodium sulfate)-challenged conditions. phenotype was systematically characterized by assessment composition using proteomics, immunofluorescence analysis selected mucin genes on mRNA level. Mucus integrity assessed in-vivo bacterial penetration into translocation sentinel organs combined fecal microbiota ex-vivo penetrability beads. All these assays revealed no relevant differences between steady state DSS-challenged conditions mouse colon. not murine
