Diseases resulting in excessive production of these factors and/or changes in the receptors, second messengers, or genes comprising their signal transduction pathways can thus result in the stimulation of continuous cell proliferation characteristic of cancer. Some carcinogenic N-nitrosamines mimic the stimulatory effect of cell-type-specific growth factors by binding to their receptors, and in this way mediate their selective carcinogenic effects.

Since activating light can be targeted specifically to tumors, and tumor-selective photosensitizing agents are being developed, this treatment has the potential to induce highly selective destruction of malignant cells. To date, PDT has been applied to a large variety of human carcinomas, resulting in successful eradication of single tumor nodules and several types of superficial tumors. Current research is aimed at improving the efficacy and tumor-selectivity and tumor destruction.

Vaccines that protect against papillomavirus infection or induce tumor regression would be beneficial in the treatment of recalcitrant warts and in preventing malignant progression.

Techniques have been developed for examining individual genes to quantitate the lesions induced by various chemotherapeutic agents and to measure the rate of gene-specific DNA repair. In mammalian cells, the DNA repair response exhibits intragenomic heterogeneity-active genes are preferentially repaired and the transcribed strand of DNA is repaired more rapidly than the nontranscribed strand. These studies have provided new insight into the molecular biology of DNA repair and a new perspective on the role of repair processes in cellular resistance to DNA damage and malignancy.

Together, raf and myc form a potent leukemogenic combination and they act synergistically to transform cells from all hemopoietic lineages.
