Mary Cheng and collaborators performed shed light into the modulation of dopaminergic signaling by targeting human dopamine transporter (hDAT). The comparison of the effects of binding dopamine (DA), amphetamine (AMPH), orphenadrine (ORPH) (repurposable drug) and cocaine to (DAT) showed that DA or AMPH drive a structural transition towards a functional form predisposed to translocate the ligand. In contrast, ORPH inhibits DAT function by arresting it in the outward-facing open conformation. Further assays show that that ORPH, like cocaine, alters DAT uptake and endocytosis.

Most recent study of Dr Gur (the Bahar lab) published in Biophys J is highlighted in Ricardo Baron's News & Notable, "Fast sampling of A-to-B Protein Global Conformational Transitions: From Galileo Galilei to Monte Carlo Anisotropic Network Modeling The new methodology, coMD, introduced by Gur et al is stated to "surely prompt new exciting routes to rapidly connect A to B, and vice versa."

"Significance of p53 dynamics in regulating apoptosis in response to ionizing radiation, and polypharmacological strategies" Liu B, Bhatt D, Oltvai ZN, Greenberger JS, Bahar ISci Rep (2014) 4:6245. PMID: 25175563

Controlling ionizing radiation (IR)-induced cell death mitigates radiation damage. Examining tumor suppressor protein p53 network dynamics in response to IR damage found that the strength of p53 transcriptional activity and its coupling (or timing with respect) to mitochondrial pore opening are major determinants of cell fate.
