The post-translational modification of histones regulates gene expression and is critical for the formation and maintenance of hippocampus-dependent long-term memories. Changes in gene-specific expression of various epigenetic marks during the aging pro-cess are sufficiently consistent as to be used as an aging landmark or epigenetic clock in both humans and other species; however, the molecular mechanisms which govern the application of these marks aging are poorly explored. Recently, long noncoding RNAs (lncRNAs) have been implicated as regulators of histone methyltransferases and other chromatin-modifying enzymes (CMEs). Despite the relevance of such mechanisms to both aging and memory formation, the behavioral relevance …


Baf Chromatin Landscaping During Bone Formation And Maintenance, Tanner Cole Godfrey Jan 2019

Baf Chromatin Landscaping During Bone Formation And Maintenance, Tanner Cole Godfrey

All ETDs from UAB

Bone loss is a worldwide problem resulting in increased risk of fracture. Osteoblasts are responsible for bone synthesis; therefore, treatments promoting osteoblast differentiation and/or activity would result in increased bone formation. The regulation of DNA accessibility is a key mechanism controlling gene expression and cellular differentiation. BAF (BRG1 Associated Factor) mediated chromatin remodeling increases DNA accessibility by sliding or ejecting nucleosomes. This process can occur in a cell type specific manner based on the composition of BAF. In many tissue types, a unique combination of BAF subunits has been identified to be responsible for the maintenance or differentiation of that …
