EMT-6 tumors were treated in vivo with 300 kVp X-rays, cyclophosphamide, or bleomycin. Tumor cell suspensions were prepared by digesting tumors with trypsin or a collagenase-deoxyribonuclease-pronase cocktail, and cells were plated in vitro for determination of fractional cell survival. Cell survival after X-rays was identical for the two disaggregation methods. Trypsin-derived cells were far more sensitive to bleomycin but less sensitive to cyclophosphamide than those prepared with the mixed enzyme cocktail. Interaction of drug produced and enzyme caused damage was the probable cause for these discrepancies. The nature of the interaction may be drug specific and therefore unpredictable. The results were unlikely to be due to different nonrepresentative tumor cell samples being produced by the two digestion methods, because the X-ray cell survival curves were so similar for the two products.

The role of base excision repair (BER) genes in Philadelphia-negative (PN)-myeloproliferative neoplasms (MPNs) susceptibility was evaluated by genotyping eight polymorphisms [apurinic/apyrimidinic endodeoxyribonuclease 1, mutY DNA glycosylase, earlier mutY homolog (E. coli) (MUTYH), 8-oxoguanine DNA glycosylase 1, poly (ADP-ribose) polymerase (PARP) 1, PARP4 and X-ray repair cross-complementing 1 (XRCC1)] in a case-control study involving 133 Caucasian Portuguese patients. The results did not reveal a correlation between individual BER polymorphisms and PN-MPNs when considered as a whole. However, stratification for essential thrombocythaemia revealed i) borderline effect/tendency to increased risk when carrying at least one variant allele for XRCC1_399 single-nucleotide polymorphism (SNP); ii) decreased risk for Janus kinase 2-positive patients carrying at least one variant allele for XRCC1_399 SNP; and iii) decreased risk in females carrying at least one variant allele for MUTYH SNP. Combination of alleles demonstrated an increased risk to PN-MPNs for one specific haplogroup. These findings may provide evidence for gene variants in susceptibility to MPNs. Indeed, common variants in DNA repair genes may hamper the capacity to repair DNA, thus increasing cancer susceptibility.
