The rat Calbindin-D9K (CaBP9K) gene is mainly
expressed in intestine, uterus, and lung and is regulated in a complex
tissue-specific manner. To analyze the role of potential regulatory
elements, previously defined by DNaseI hypersensivity, we made
transgenic mice containing truncated rat CaBP9K fusion gene with simian
virus 40 large T antigen and the chloramphenicol acetyltransferase as
reporter genes. The transgenes contained CaBP9K promoter fragments with
5 end points at 4400, 1011, and 117 base pairs (bp), whereas the
3 end points was at +365 bp. Northern blot analysis of T antigen
expression and chloramphenicol acetyltransferase enzyme-linked
immunosorbent assay indicated that a positive element, probably the
distal intestine-specific DNaseI HS, necessary to target the expression
of the transgene in the intestine, is present between 4400 and 1011
bp. The cephalo-caudal gradient of expression of the transgene along
the small intestine was similar to those of the endogenous gene, but an
ectopic expression of the transgene was observed in the colon. The
1011 transgene was expressed in epithelial alveolar cells of the
lung, in renal proximal tubule cells, and in uterine myometrium, as
judged from immunocytochemical, histological, and Northern blot
analyses. The shortest, 117 construct was only expressed in uterine
myometrium, and it was under a strict estrogen dependence like the
endogenous gene. Finally, responsiveness to vitamin D in the duodenum
was observed with the largest, 4400 construct. Thus, different
tissues utilize distinct cis-acting elements to direct and regulate the
expression of the rat CaBP9K gene.
