title: A novel isoform of rat hepatocyte nuclear factor 4 (HNF-4).
abstract: Based on the published nucleotide sequence for rat hepatocyte nuclear factor 4 (HNF-4; Sladek, F.M., Zhong, W., Lai, E. and Darnell, J.E., Jr. (1990) Genes Dev. 4, 2353-2365), we have cloned a cDNA by means of polymerase chain reaction amplification of reverse-transcribed RNA (RT-PCR). Our clone contained an extra segment of 30 bp, which was not found in the previously reported clone, in the coding region near the C-terminus. Further RT-PCR analysis demonstrated that both isoforms of HNF-4 mRNA, i.e., with or without the 30 nucleotide segment, occur in rat liver and kidney, presumably by differential splicing.
