Researches at the University of Maryland School of Medicine, discovered that a protein interferes with the cell's ability to respond and repair DNA damage which is a known origin of cancer. The protein found is called DnaK which is a protein of mycoplasma bacteria. This was very interesting because I was unaware of the fact that bacterial infections (specifically mycoplasma bacteria) are found to cause forms of cancers. According to this article: "currently, approximately 20% of cancers are thought to be caused by infection". The researchers created a study in which they studied the effect of mycoplasma infections on the development of lymphoma. The study compared non-infected mice and how quickly they developed lymphoma to mice that were infected with mycoplasma. The study concluded that the mycoplasma infection led to an earlier development of lymphoma and that many cancer cells had the bacterial DNA of the mycoplasma, which meant that the infection did not have to persist to trigger cancer. Mycoplasma bacteria tend to be found in humans infected with HIV, meaning they are at a higher risk.
