In the present study, we have identified a cellular context (the interleukin-2 [IL-2]-dependent HT-2 line ) in which the EPO stimulation of the EPOR fails to support cellular proliferation, STAT-5 induction , or MAPK activation , despite efficient phosphorylation of the EPOR and JAK2 and inhibition of apoptosis after withdrawal of IL-2 .
 protein: EPOR; protein: IL-2; protein: MAPK; protein: EPO; protein: STAT-5; cell line: interleukin-2 [IL-2]-dependent HT-2 line; protein: EPOR; protein: JAK2
