We lack tools to edit DNA sequences at scales necessary to study 99% of the human genome that is noncoding. To address this gap, we applied CRISPR prime editing to insert recombination handles into repetitive sequences, up to 1697 per cell line, which enables generating large-scale deletions, inversions, translocations, and circular DNA. Recombinase induction produced more than 100 stochastic megabase-sized rearrangements in each cell.

Pre-implantation genetic testing for aneuploidy (PGT-A) via embryo biopsy helps in embryo selection by assessing embryo ploidy. However, clinical practice needs to consider the invasive nature of embryo biopsy, potential mosaicism, and inaccurate representation of the entire embryo. This creates a significant clinical need for improved diagnostic practices that do not harm embryos or raise treatment costs.

Chronic lymphocytic leukemia (CLL) is a less common hematological malignancy in Indian people. It accounts for less than 5% of all leukemias. Information on genomic alteration in CLL is limited immunoglobulin heavy-chain variable region (IGHV) mutational status is considered the most reliable prognostic marker.

Although atomoxetine, a selective norepinephrine reuptake inhibitor, is widely used in the treatment of attention-deficit/hyperactivity disorder (ADHD), there is limited data on its cytogenetic effects. This study aimed to investigate the cytotoxicity and genotoxicity of atomoxetine and . Chromosome aberration and micronucleus assays were used to analyze the genotoxic effect of atomoxetine in human peripheral blood lymphocytes under culture conditions.
