Moffitt researchers say silencing of retinoblastoma gene regulates differentiation of myeloid cells
Date:2/19/2013

SCs and that it "appears that, in cancer, M-MDSCs probably acquire the ability to differentiate into PMN-MDSCs" and "may represent an important pathways for the accumulation of these cells in contrast to normal monocytes."

"We demonstrated that HDAC-2 can directly interact with Rb1 promoter and participate in silencing Rb1 expression," said study co-author Vinit Kumar, Ph.D., also a post-doctoral fellow in the Gabrilovich laboratory. He added that "silencing Rb1 expression in monocytes and other myeloid progenitors may be critical to the accumulation of PMN-MDSCs."

"If the role of HDAC-2 in this process is confirmed, the finding may offer an opportunity for therapeutically targeting myeloid cells in cancer and possibly in other pathologic conditions," concluded the researchers.
