Tyrosine 101-109 signal transducer and activator of transcription 3 Rattus norvegicus 125-130 21186585-5 2006 RESULTS: The level of tyrosine-phosphorylated STAT3 increased at 6 h and peaked at 12 h. The expression of c-myc mRNA increased after 2 h of hypoxia and reached maximal level at 4 h, then declined at 6 h and to the basal levels at 12 h. With the prolonging of hypoxia time, 3H-TdR incorporation in PASMC under hypoxia conditions was significantly higher. Tyrosine 22-30 signal transducer and activator of transcription 3 Rattus norvegicus 46-51 21186585-6 2006 AG490 inhibited proliferation of PASMCs by preventing STAT3 tyrosine phosphorylation and the expression of c-myc under hypoxia conditions. Tyrosine 60-68 signal transducer and activator of transcription 3 Rattus norvegicus 54-59
