Since the expression of the brain specific metallothionein isoform, MT-3, was shown to be expressed in many, but not all prostate cancers, this gene was transfected into the commonly utilized prostate tumor cell line, PC-3, to study the consequence of MT-3 expression on growth rate and resistance to chemotherapeutic agents.

520 $a Since the expression of the brain specific metallothionein isoform, MT-3, was shown to be expressed in many, but not all prostate cancers, this gene was transfected into the commonly utilized prostate tumor cell line, PC-3, to study the consequence of MT-3 expression on growth rate and resistance to chemotherapeutic agents.
520 $a PC-3 cells were stably transfected with MT-3 or MT-1E under control of the constitutive CMV promoter. The levels of MT-3 protein for the 5 overexpressing clones had an average level of 8.3 ng MT-3 per mug protein as assessed by quantitative immunodot blot analysis, and three were picked for further analysis. MT-3 expressing clones had a slower growth rate (63 hr doubling time) compared to vector-only transfected cells (35 hr doubling time). The MT-1E overexpressing clones had total MT-1/2 levels of 5.54 +/- 0.85 ng/mug of protein whereas clones from vector-only transfection had 0.90 +/- 0.05 ng/mug protein. The mean doubling time of the three independent clones of PC-3 cells overexpressing MT-1E was 39.2 hr compared to 36.7 hr for control PC-3 cells, and 39.9 hr for blank vector transfectants.
520 $a The effect of these two isoforms of MT on cellular resistance to commonly utilized chemotherapeutic agents was determined on MT-3 and MT-1E expressing and non-expressing clones of PC-3 cells exposed to cadmium, cisplatin, vinblastine, paclitaxel, etoposide, and mitoxantrone. Both MT-3 and MT-1E expression in PC-3 cells conferred resistance to all five chemotherapeutic agents, with a 10-fold increase in resistance to paclitaxel and mitoxantrone for the MT-1E transfected clones compared MT-3 transfected clones.
