Etoposide 43-52 sphingosine-1-phosphate receptor 1 Homo sapiens 10-15 28716816-5 2017 Elevated S1PR1 expression and STAT3 activation are also observed in human NB cells with acquired resistance to etoposide. Etoposide 111-120 sphingosine-1-phosphate receptor 1 Homo sapiens 9-14 28716816-6 2017 We show in vitro and in human NB xenograft models that treatment with FTY720, an FDA-approved drug and antagonist of S1PR1, dramatically sensitizes drug-resistant cells to etoposide. Etoposide 172-181 sphingosine-1-phosphate receptor 1 Homo sapiens 117-122
