Abstract
We studied the effects of polyphenolic composition BP-C2, comprising molybdenum with lignin derivatives, on lung carcinogenesis induced by urethane in the progeny of F0 male BALB/c mice preconceptionally exposed to radiation in a dose of 1 Gy. The multiplicity of lung tumors in the progeny of irradiated mice was higher than in the progeny of non-irradiated male parents by 50% in females and 43% in males (p<0.05). In F1 mice (progeny of irradiated F0 male parents treated with BP-C2), the multiplicity of lung tumors was also higher, but this increase was less pronounced: 35% in females (p=0.3852) and 23% in males (p=0.0766). We have demonstrated that administration of BP-C2 to irradiated parents (F0) efficiently inhibits carcinogenesis in their F1 progeny. The use of BP-C2 in irradiated male parents and their progeny not only reduced the multiplicity of tumors, but also normalized body weights in the F1 progeny. Our study demonstrates potential of the polyphenolic composition BP-C2 for chemoprophylaxis of radiation-induced transgenerational carcinogenesis.

Abstract
Nitrogen mustards (NM) are an important class of chemotherapeutic drugs used in the treatment of malignant tumors. The accepted mechanism of action of NM is through the alkylation of DNA bases. NM-adducts block DNA replication in cancer cells by forming cytotoxic DNA interstrand cross-links. We previously characterized several adducts formed by reaction of bis(2-chloroethyl)ethylamine (NM) with calf thymus (CT) DNA and the MDA-MB-231 mammary tumor cell line. The monoalkylated N7-guanine (NM-G) adduct and its cross-link (G-NM-G) were major lesions. The cationic NM-G undergoes a secondary reaction through depurination to form an apurinic (AP) site or reacts with hydroxide to yield the stable ring-opened N5-substituted formamidopyrimidine (NM-Fapy-G) adduct. Both of these lesions are mutagenic and may contribute to secondary tumor development, a major clinical limitation of NM chemotherapy. We established a kinetic model with NM-treated female mice and measured the rates of formation and removal of NM-DNA adducts and AP sites. We employed liquid chromatography-mass spectrometry (LC-MS) to measure NM-G, G-NM-G, and NM-Fapy-G adducts in liver, lung, and spleen over 168 h. NM-G reached a maximum level within 6 h in all organs and then rapidly declined. The G-NM-G cross-link and NM-FapyG were more persistent with half-lives over three-times longer than NM-G. We quantified AP site lesions in the liver and showed that NM treatment increased AP site levels by 3.7-fold over the basal levels at 6 h. The kinetics of AP site repair closely followed the rate of removal of NM-G; however, AP sites remained 1.3-fold above basal levels 168 h post-treatment with NM. Our data provide new insights into NM-induced DNA damage and biological processing in vivo. The quantitative measurement of the spectrum of NM adducts and AP sites can serve as biomarkers in the design and assessment of the efficacy of novel chemotherapeutic regimens.
