Novel Role of the ALPI Gene Associated with Constipation Caused by Complement Component 3 Deficiency.

ABSTRACT: Complement component 3 (C3) deficiency has recently been reported as one of the novel causes of constipation. To identify a unique gene specific to constipation caused by C3 deficiency, the total RNA extracted from the mid colon of C3 knockout (C3 KO) mice was hybridized to oligonucleotide microarrays, and the function of the candidate gene was verified in in vitro and in vivo models. C3 KO mice used for microarrays showed definite phenotypes of constipation. Overall, compared to the wild type (WT), 1237 genes were upregulated, and 1292 genes were downregulated in the C3 KO mice. Of these, the major genes included were lysine (K)-specific demethylase 5D (KDM5D), olfactory receptor 870 (Olfr870), pancreatic lipase (PNLIP), and alkaline phosphatase intestinal (ALPI
