Circadian clock and stress interactions in the molecular biology of psychiatric disorders

D Landgraf, MJ McCarthy, DK Welsh - Current psychiatry reports, 2014 - Springer
Many psychiatric disorders are characterized by circadian rhythm abnormalities, including
disturbed sleep/wake cycles, changes in locomotor activity, and abnormal endocrine function. …

Segregation of molecules at cell division reveals native protein localization

D Landgraf, B Okumus, P Chien, TA Baker… - Nature methods, 2012 - nature.com
We introduce a nonintrusive method exploiting single-cell variability after cell division to
validate protein localization. We found that Clp proteases, widely reported to form biologically …

[PDF][PDF] Lipidomic analysis of α-synuclein neurotoxicity identifies stearoyl CoA desaturase as a target for Parkinson treatment

…, GPH Ho, T Noble, J Sandoe, Y Lou, D Landgraf… - Molecular cell, 2019 - cell.com
In Parkinson's disease (PD), α-synuclein (αS) pathologically impacts the brain, a highly lipid-rich
organ. We investigated how alterations in αS or lipid/fatty acid homeostasis affect each …
