Loss of gene releases mutation-generating protein, rendering cancers resistant to treatment, UTSW researchers find

Loss of a gene known as SYNCRIP in prostate cancer tumors unleashes cellular machinery that creates random mutations throughout the genome that drive resistance to targeted treatments, a team led by UT Southwestern Medical Center researchers discovered. The findings, published in Cancer Cell, could lead to interventions that thwart this process in prostate and other cancer types, making them far easier to treat.

Study shows how Epstein-Barr transforms B cells

Epstein-Barr virus infection is known to convert resting B lymphocytes into immortal cells that continuously multiply, which leads to posttransplant lymphoproliferative disorder and can evolve to lymphoma and other lymphoproliferative disorders. In a recent study, Japanese researchers discovered the molecular mechanisms of this growth transformation, demonstrating the Epstein-Barr virus induces nucleolar enlargement and increased proliferation in B cells by activating the cancer-related gene IMPDH2.
