Modulation of multidrug resistance by verapamil or mdr1 anti-sense oligodeoxynucleotide does not change the high susceptibility to lymphokine-activated killers in mdr-resistant human carcinoma (LoVo) line.


Two sublines were derived from the colon adenocarcinoma line LoVo, the first one was sensitive (LoVo/H) and the second one was made resistant to doxorubicin (LoVo/Dx). When tested for susceptibility to lysis by different types of immune effectors, LoVo/Dx appeared more sensitive than LoVo/H to the killing of CD3+CD5+CD16-, CD3- CD16+)-enriched lymphokine… (More)
