Scientists uncover a new approach for treating aggressive cancer

The Pharma Data

UNC researchers now show that these two factors can directly associate with one another, modulating cancer-cell-specific programs of gene expression. ” They found that EZH2 possesses two different binding patterns on chromatin in acute leukemia cells, eliciting two distinct gene-regulatory programs (Figure 1).
