Compositions and methods based upon an isoform of p53

摘要

The present invention is directed to an isoform of the p53 tumor suppressor and to polynucleotides that encode this isoform. The isoform may be used as a marker to indicate that cardiac cells have experienced hypoxia, as would occur during a myocardial infarction. In addition, vectors encoding the isoform may be transfected into cells as a means of regulating proliferation.
