lymphatic cancer, mitochondria, mitochondrial RNA transport, PNPase, PNPT1, NF-Y


Lymphoma is the most common type of blood cancer today and, as its name suggests, it begins in the lymphatic system. The origin of this disease is related to mitochondrial defects, generated by mutations in the PNPase enzyme or polynucleotide phosphorylase, whose main functions are to import and degradation mitochondrial RNA. For this reason, the main objective of the present work was to carry out a bibliographic review of scientific publications that made the role of this enzyme relevant, in relation to mitochondria as the cause of lymphatic cancer.

The methodology used consisted of a bibliometric analysis based on the use of different databases, in which search equations formed from keywords were introduced. Then, the selection of articles related to the study topic and published in the last 20 years was carried out. Subsequently, the journals were analyzed, based on the H index, in order to observe which supported the hypothesis of the role of PNPase in lymphoma and which stated the opposite.

The results showed that a total of 441,288 scientific publications were obtained, of which 133 were selected to carry out this work. As for the journals, those with the highest H index were Nature and Cell.

It can be concluded that PNPase plays a very important role in the transport of mitochondrial RNA, and that the factor NF-Y is involved in the control of cell growth, therefore, both have a crucial role in the development of this disease. Therefore, research on both PNPase and NF-Y is essential to establish the specific genetic characteristics that define the early lesions of lymphatic cancer and the consequent determination of their treatment.
