Since many cellular oncogenes were originally identified in transforming retroviruses, and since some retroviruses cause rapid malignant transformation in animals, notably chicken, it seemed for a while that most human cancers are caused by infection with retroviruses. But that is not the case. The number of human cancers which originate from retroviral infections is actually rather small (Table 15.2). In many cases, proto-oncogenes can become oncogenes by mutation or overexpression in human cells, without retroviral assistance.

Association between viral infection and motor neuron disease is based upon cases of motor neuron disease due to retroviral infection (HIV, HTLV-1) and the presence of serum antibodies directed toward endogenous retroviral gene sequences in ALS patients. 

Fig. 7.1. The figure illustrates the hypothetical results obtained from three different cell clones after random integration of a marker gene, following either plasmid transfection or retroviral infection. Genomic DNA digestion with the restriction enzymes A, B or C will result in a unique band pattern, which is suggestive of the integration events in each cell clone.
