It is unfortunate that Cymbaluk-Ploska et al. [29] did not compare MMP-3 concentrations between OC and BL patients and healthy subjects; since this is the only such study available, we are unable to relate our results to other work—according to the results we obtained, healthy women had significantly lower MMP-3 concentrations (median: 7.97 ng/mL) than OC and BL patients. The gene discussed is MMP3; the disease is Burkitt lymphoma.
