STAT5 has been found to be constitutively phosphorylated in cancer cells, implying that the protein is always present in its active form. This constant activation is brought about either by mutations or by aberrant expressions of cell signalling, resulting in poor regulation, or complete lack of control, of the activation of transcription for genes influenced by STAT5. This leads to constan… WebThe JAK2 inhibitor tyrphostin AG490 blunted STAT5 phosphorylation and rhEPO-induced cytoprotection of CA1 neurons. These results show STAT5 to be a mediator of erythropoietin's neuroprotective mechanisms, but do not exclude the contributions of other signaling mechanisms downstream of JAK2. jesus rei
