To identify novel homeodomain transcription factors expressed in pancreatic beta cells that participate in beta-cell differentiation and insulin gene regulation.
Designed degenerate PCR primers targeting conserved sequences of homeobox genes cdx3, lmx1, and Antennapedia.
Amplified and cloned complementary DNA inserts from an insulinoma cDNA library.
Profiled the expression patterns of identified homeobox genes using Northern blot analysis.
Cloning yielded sequences encoding 10 distinct homeodomain proteins, 3 of which were previously undescribed.
Identified an alternative splice variant of engrailed-2, a homeobox gene previously characterized in the central nervous system.
Northern analysis confirmed distinct expression patterns for each gene, while omission of cdx3 and lmx1 among recovered clones indicates an even broader uncaptured homeobox repertoire.
