A cross ancestry genetic study of psychiatric disorders from India

B. Holla, J. Mahadevan, S. Ganesha, R. Sud, M. Janardhanan, S. Balachander, N. Strom, M. Mattheisen, P. F. Sullivan, H. Huang, P. Zandi, V. Benegal, J. Y. Reddy, S. Jain, CVEDA collaborators, , B. Viswanath

This study evaluates the predictive accuracy of polygenic scores for psychiatric disorders in an Indian population using European GWAS data, finding moderate-to-high accuracy for bipolar disorder but lower for OCD and externalizing traits.

Dynamics of endogenous PARP1 and PARP2 during DNA damage revealed by live-cell single-molecule imaging

J. Mahadevan, A. Jha, J. Rudolph, S. Bowerman, D. Narducci, A. S. Hansen, K. Luger

This study uses live-cell single-molecule imaging to show that most PARP1/2 diffuse freely, with a small fraction transiently binding DNA after damage, suggesting new strategies for PARP inhibitors.

Automated Modeling of Protein Accumulation at DNA Damage Sites using qFADD.py

S. Bowerman, J. Mahadevan, P. Benson, J. Rudolph, K. Luger

The paper introduces qFADD.py, an open-source tool for analyzing DNA damage repair protein dynamics using automated fitting and simulation, improving upon previous methods with better statistical rigor and user-friendliness.

Bridging of nucleosome-proximal DNA double-strand breaks by PARP2 enhances its interaction with HPF1

G. Gaullier, G. Roberts, U. M. Muthurajan, S. Bowerman, J. Rudolph, J. Mahadevan, A. Jha, P. S. Rae, K. Luger

The paper presents a cryo-EM structure of PARP2 bridging nucleosome-proximal DNA breaks and shows its interaction with HPF1 in a functional complex.

Q-FADD: A mechanistic approach for modeling the accumulation of proteins at sites of DNA damage by free diffusion

J. Mahadevan, J. Rudolph, A. Jha, J. W. Tay, J. Dragavon, E. M. Grumstrup, K. Luger

The paper introduces a free diffusion model to quantify protein accumulation at DNA damage sites in live cells, applied to poly-ADP-ribose polymerases 1 and 2.

Poly(ADP-ribose) polymerase 1 Searches DNA via a ‘Monkey Bar’ Mechanism

J. Rudolph, J. Mahadevan, P. N. Dyer, K. Luger

This study reveals that PARP1 searches DNA using a 'monkey bar' mechanism, where DNA binding facilitates release, and identifies the WGR-domain as essential for this process.
