Abstract:
A side-by-side comparison of several normal mouse and human tissues was undertaken in order to determine if exon-deleted variant ER-alpha mRNAs are expressed in the mouse. The data showed that the complex pattern of ER-alpha alternative splicing that is detected in multiple human tissues was not apparent in murine tissues. Only low levels of an exon-4 deleted ER-alpha transcript were detected in murine tissues, although multiple relatively abundant exon-deleted ER-alpha transcripts were detected in human tissues. The data support a species-specific difference in the expression of ER-alpha variant mRNAs between mouse and human.
