Lung infection with Mycobacterium tuberculosis is associated with lung cancer. Thus, individuals with a history of pulmonary tuberculosis are at higher risk of developing lung cancer. However, there is little information on the involvement of M. tuberculosis in the etiology of lung neoplasia. It has been described that M. tuberculosis damages the DNA of human cells, although it is not known how. One possible mechanism would be through secreted proteins that target the nucleus as part of its virulence. In the present study, we set out to predict the proteins secreted by M. tuberculosis that target the host cell nucleus via passive diffusion, and their potential interaction with DNA. Using bioinformatics procedures, we discovered that of the 972 proteins that make up the M. tuberculosis secretome, 58 proteins target the host cell nucleus. Of these, 3 proteins (30S ribosomal protein S3, transcriptional regulatory protein Rv3488 and formamidopyrimidine-DNA glycosylase) have a high probability of interacting directly with DNA. Our results support the link between M. tuberculosis infection and lung cancer, and this group of secretion proteins destined to the nucleus may have the potential to alter genome functions by interacting with nucleic acids.
