Primary Specialty:
Cancer Biology-Mechanistic Studies of DNA Repair
Curriculum Vita

Dr. Wani has been involved in delineating the intricate mechanisms of DNA damage repair for about four decades. His research has utilized a variety of model systems and damaging agents to study several DNA repair pathways. Initial research dealt with revealing the functional features of the individual pathway components in the DNA damage response milieu. Latest efforts have focused on closer inspection and discerning the cross-talk between DNA repair and other associated DNA-templated processes, e.g., chromatin remodeling, transcription, checkpoint activation/deactivation, post-translational protein modifications, protein degradation and documenting the initial status and subsequent fate of DNA damage-modifiable epigenetic histone marks. Having successfully revealed the mechanisms of processing from the perspective of an entire genome or at a single-nucleotide resolution, his research focus has been further sharpened by studies of authenticating DNA repair within the chromatin context. His laboratory was first in the USA to utilize a unique whole-cell based approach for assessing DNA damage and repair within discrete UV radiation-damaged sub-nuclear areas (micropore irradiated foci). For over a decade of the latest multipronged studies, this approach has proven a boon for not only asking questions related to distinct DNA damage responses, but assessing the ‘coming and going’ of a host of individual factors and protein complexes and reveal the spatio-temporal relationships of these proteins with regards to their position and function in different upstream and downstream events of damage response in native environment of the cell. His core research group has extensively published on these facets as well as the interplay of histone modifications, either occurring directly at the site of lesions within chromatin or being deposited as part of newly reconstituted chromatin at the DNA lesion repair sites. As would be expected, his laboratory has deployed a range of state-of-the-art technologies that specifically address his research related goals. Dr. Wani enjoys and takes pride in working on the bench himself and help develop the nitty-gritty protocol details for various old and new experimental procedures, streamlining these for optimum time and resource utilization and the highest quality and quantity of research output. Dr. Wani has devoted himself to exhaustively explore and develop newer paradigms in the realm of molecular oncology, and disseminate the latest and evolving concepts in diverse settings. His overarching goal is to continue work towards the molecular dissection of the processing of genomic lesions and unravel the cross-talk among closely related network of pathways with the ultimate aim of developing intervention strategies for elimination of diseases emanating from inherent instability of the human genome.

Research work in Wani lab has been continuously funded by NIH grants since 1984.
