Function Of Mllt3 In Liver Metabolism, Grace Ann Hammack

Master's Theses

The chromatin regulator MLLT3 recognizes target genes through the YEATS domain that identifies post-translationally modified histones, with preference for crotonyl and acetyl marks, and recruits different multiprotein effector complexes through its C-terminal domain to target genes. To study the role of MLLT3 in gene regulation, the Zeleznik-Le and Hemenway labs developed Mllt3 whole-body knockout (Mllt3;Rosa26-CreERT2) mice. These mice have a hematopoietic stem cell phenotype and an unexpected obesity and hepatic steatosis phenotype. It was unknown whether these phenotypes were from liver intrinsic effects or influenced by other parts of the body. To study this fatty liver phenotype further, Mllt3;Alb-Cre were …
