The DNA Center at the University of Babylon held a workshop presented by the teacher, Ali Muhammad Abd al-Amir, on (JAK-STAT Signing Pathways in Cancer), in the presence of a number of Academic Staff, postgraduate students, and researchers. The lecturer touched on the general definition of these pathways, their types and locations in immune cells and their important role in transporting some interleukin proteins to other immune cells through phosphorylation, their transmission to the nucleus and transcription of the gene responsible for immune cells. The expression of interleukins and inflammatory immune proteins, in addition to that in the event of a mutation in these genes, their role is negative in unlimited cell proliferation, and they may transform into tumor cells as a result of damage to the gene. Research has also shown that treating some of these mutations may reduce or prevent the occurrence of these types of cancers
