Abstract	Inhalation of mixtures of insoluble and soluble nickel compounds by humans during nickel refining has been associated with excess lung and nasal sinus cancers. Insoluble nickel subsulfide (Ni$_{3}$S$_{2}$) and nickel oxide (NiO) are carcinogenic to rodents by inhalation. We previously showed that insoluble Ni$_{3}$S$_{2}$, crystalline nickel monosulfide (NiS), and green (high temperature, HT) and black (low temperature, LT) NiO, induced morphological transformation in cultured C3H/10T1/2 Cl 8 (10T1/2) mouse embryo cells. To understand molecular mechanisms of carcinogenesis by insoluble nickel compounds, we used random, arbitrarily primed-polymerase chain reaction (RAP-PCR) mRNA differential display and identified nine cDNA fragments that were differentially expressed between nontransformed and nickel-transformed cell lines in ~ 10.0% of the total mRNA. Expression of the calnexin gene (encoding a type I membrane protein/molecular chaperone), the ect-2 proto-oncogene, and the stress-inducible gene, Wdr1, was upregulated. Expression of six genes – the vitamin D interacting protein/thyroid hormone activating protein 80 (DRIP/TRAP-80) gene, the insulin-like growth factor receptor 1 (IGFR1) gene, the small nuclear activating protein (SNAP C3) gene, and three unknown genes, was down-regulated, in nickel-transformed cell lines. We hypothesize that these resulting aberrations in gene expression could contribute to the induction and/or maintenance of morphological transformation induced by specific insoluble nickel compounds.
