Research Abstract |
We demonstrated that 8-OHdG was generated in polymorphonuclear leukocytes (PMN). The 8-OHdG in PMN was observed in all investigated populations, while it was frequently found along with the elevated amounts of cell debris in individuals with skin lesion including hypopigmentation and keratosis in arsenic exposed participants of Shanxi province, China. After the human skin cell line (HaCaT) was exposed to an environmentally relevant level of arsenic 0.05 ppm for about 4 months, we determined the8-nitroguanine and cancer stem cell marker CD44v6 in the acquired cancer phenotype. Treated cells with arsenic became apparently tumorigenic, that pathological studies of xenograft tumor in nude mice showed highly undifferentiated tumors.
