The invention is based on the finding that in mammalian lungs c-myc acts as a molecular switch, specifically inducing an expression pattern in vivo, which results in prototypical mammalian adenocarcinoma of the lung and liver metastasis. A set of factors essential for the processes of tumorigenesis and tumor progression, i.e. cell cycle and apoptosis, cell growth, extracellular signaling, angiogenesis and invasion, is identified, whose expression is significantly changed. In particular, the expression pattern found uncovers the network of molecules leading to mammalian papillary adenocarcinomas of the lung.

There is provided a method for inhibiting ATF/CREB and cancer cell growth using disulfiram, administered in combination with heavy metals. It was found that disulfiram disrupts transcription factor DNA binding by forming mixed disulfides with thiols within the DNA-binding region, and that this process is facilitated by metal ions. Disulfiram administered to melanoma cells in combination with copper (II) or zinc(II) decreased expression of cyclin A, reduced proliferation in vitro, and inhibited growth of melanoma cells. The combination of oral zinc gluconate and disulfiram at currently approved doses for alcoholism stabilized tumor growth in two of three patients with Stage IV metastatic melanoma, with 12 and 17 month survivals, respectively, to date, and produced a >50% reduction in hepatic metastases in one individual.

The invention provides interfering RNA and a lentivirus vector targeted to the OLFM4 gene and application of the interfering RNA and the lentivirus vector in preparation of drugs used for preventing and treating metastasis of stomach cancer tumors to the abdominal cavity or/and the liver.
