US Patent 7973156 Hypoxia-regulated genes

According to the present invention, purified, isolated and cloned nucleic acid polynucleotide encoding hypoxia-regulating genes and the proteins thereof and antibodies directed against the proteins which have sequences as set forth in SEQ ID No:1, SEQ ID No:2, SEQ ID No:3, SEQ ID No:4, SEQ ID No:5 and SEQ ID No:6 are provided. The present invention further provides transgenic animals and cell lines as well as knock-out organisms of these sequences. The present invention further provides methods of regulating angiogenesis or apoptosis or regulating response to hypoxic conditions in a patient in need of such treatment. The present invention also provides a method of diagnosing the presence of ischemia in a patient including the steps of analyzing a bodily fluid or tissue sample from the patient for the presence or gene product of at least one expressed gene (up-regulated) as set forth in the group comprising SEQ ID No:2; SEQ ID No:3; SEQ ID No:4; SEQ ID No:5; and SEQ ID No:6 and where ischemia is determined if the up-regulated gene or gene product is ascertained.
