LINE-1 transposon derived DNA lesions reshape the chromatin landscape to promote genome instability

Arun Kumar, Ankita Subhadarsani Parida, Kiran Bhatoa, Sunil K. Raghav, Bhavana Tiwari

This study shows that LINE-1 endonuclease activity causes DNA damage and chromatin remodelling in melanoma cells, with p53 modulating this process.

Recurrent LINE 1 exonization drives transcriptome remodelling in NSCLC

Ankita Subhadarsani Parida, Arun Kumar, Bhavana Tiwari

This study identifies recurrent LINE-1 exonization events in NSCLC that generate new transcript isoforms, contributing to transcriptome diversity without affecting gene expression levels.

p53 mediated regulation of LINE1 retrotransposon derived R-loops

Pratyashaa Paul, Arun Kumar, Astik Kumar De, Ankita Subhadarsani Parida, Gauri Bhadke, Satyajeet Khatua, Fizalin Pattanayak, Bhavana Tiwari

This study shows p53 suppresses L1 retrotransposon-derived R-loops by recruiting repressive epigenetic marks and inhibiting activating marks, preventing DNA damage and inflammation.

Contributions of the conserved insect carbon dioxide receptor subunits to odor detection

Arun Kumar, Genevieve M. Tauxe, Sarah Perry, Christi Ann Scott, Anupama Arun Dahanukar, Anandasankar Ray

This study shows that Gr2 and Gr3 subunits are sufficient for CO2 detection in Drosophila, while Gr1 modulates sensitivity and ligand diversity.
