Decade-long search in one-celled, fresh water dwelling organism solves puzzle involved in gene regulation

After an intrepid, decade-long search, Johns Hopkins Medicine scientists say they have found a new role for a pair of enzymes that regulate genome function and, when missing or mutated, are linked to diseases such as brain tumors, blood cancers and Kleefstra syndrome - a rare genetic, neurocognitive disorder.

Protein complex may present strong therapeutic target for lethal breast cancer

Researchers at Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine have shown that a protein complex that governs gene expression (called CoREST) sometimes gets rewired during breast cancer to help estrogen receptor positive (ER+) tumors resist endocrine therapies and become more aggressive.
