Rs. Stoika et al., Murine L1210 leukemia cells resistant to cis-diaminedichloroplatinum(II) action are also refractory to beta 1-induced growth inhibition, EXP ONCOL, 20(3-4), 1998, pp. 256-258
Murine L1210 leukemia cells possessing an increased resistance to cis-diami
nedichloroplatinum (II) (cDDP) were found to be refractory to the transform
ing growth factor (TGF) beta 1-induced growth inhibition, while the parenta
l L1210 cells were strongly inhibited by this cytokine. Growth inhibition w
as estimated on the basis of H-3-thymidine incorporation and direct cell co
unting. These results suggest the existence of cross-resistance to cDDP and
TGF-beta 1 in the studied leukemia cells.
