ER stress-associated IRE1α signalling links impaired QPRT-dependent NAD⁺ biosynthesis to reduced oocyte competence

Mohd Athar, Ajith Kumar E, Pravin Birajdar, Rajender M, Akshay Kumar, Anjali Kumari, Sahina Sabnam, Ankita Verma, Pradnya. L, Partha Sarathi Nial, Taru Sharma G, HBD Prasada Rao

This study links ER stress and impaired NAD biosynthesis via QPRT to reduced oocyte quality and shows that NMN supplementation improves oocyte function and early embryonic development.

CDK1 facilitates RAD51-mediated DNA repair to protect dictyate stage arrested oocytes from genotoxic stress

Ajith Kumar, P. Lava Kumar, Pravin Birajdar, Akshay Kumar, Anjali Kumari, Kiran Kumar P, Mohd Athar, Aradhana Mohanty, Ankita Verma, Pradnya. L, Sowmya. G, Rajender M, S Abhilasha, Sahina Sabnam, Partha Sarathi Nial, , H. B. D. Prasada Rao

This study identifies CDK1 as a critical regulator of DNA repair in dictyate-arrested oocytes, showing it facilitates RAD51-mediated homologous recombination to protect against genotoxic stress.

Lipid Droplet Remodeling Safeguards Redox Balance through the DGAT1-PANK2-NRF2 Axis in Mammalian Oocytes and Drives Age-Associated Decline

Pravin Birajdar, Akshay Kumar, Anjali Kumari, Aradhana Mohanty, Mohd Athar, Ajith Kumar, Kiran Kumar P., S Abhilasha, Sahina Sabnam, Silambresan Y, Ankita Verma, Menda Rajendar, H. B. D. Prasada Rao

This study identifies the DGAT1-PANK2-NRF2 axis as critical for lipid droplet remodeling, redox balance, and oocyte quality, with dysfunction linked to age-related decline.
