The presence of human progesterone receptor (PR) mRNA variants has been demonstrated in uterine endometrium and breast tissues as well as in cancer cells of these tissues. While exon deletions by the alternative splicing in these variants have been reported, there are few reports available on the PR mRNA variants with exon insertion. In the present study, we attempted to detect a PR mRNA variant containing the exon insertions in normal uterine endometrium. Endometrial tissues were subjected to reverse transcription-polymerase chain reaction (RT-PCR) with PCR primers which were located in exons 3 and 8. Analysis of the RT-PCR products revealed the presence of a novel PR mRNA variant which contained a 232 bp inserted nucleotide sequence between exons 4 and 5. We termed this transcript the "i45 PR mRNA variant". Genomic analysis indicated that the inserted sequence was derived from two novel independent exons of 123 bp and 109 bp, termed "exon i45a" and "exon i45b", respectively, which are located between exons 4 and 5 of the human PR gene. The i45 PR mRNA variant was further detected in uterine endometrial cancer tissues as well as in the normal uterine endometrium. These results demonstrate the presence of a novel PR mRNA variant with exon insertions in the human tissue for the first time. The i45 PR variant protein, possibly transcribed from this i45 PR mRNA variant, may play physiological and/or pathological roles in the human uterine endometrium.
