Aim: False positives in CRISPR–Cas9 screens can arise from Cas9-mediated DNA cleavage inducing gene-independent antiproliferative effects. This unintended consequence, resulting in inaccurate essentiality predictions, underscores the critical need to address and correct for the copy number effect. Overcoming this challenge is pivotal for enhancing the specificity of CRISPR–Cas9 essentiality screens in cancer cells, ensuring more reliable identification of truly essential genes for targeted therapeutic interventions. This is an experimental study which aims to implement a computational correction approach to mitigate the impact of the copy number effect and improve the accuracy of essentiality assessments in cancer research. It addresses the issue of false positives in CRISPR–Cas9 screens due to Cas9-mediated DNA cleavage's gene-independent antiproliferative effect.

Methodology: The experiment is a genome-scale CRISPR-Cas9 loss-of-function screening in cancer cells, employing the Avana sgRNA library for genomic data and the CERES software for data analysis. It involves processing sgRNA activity and cell line responses, with data sourced from the Cancer Cell Line Encyclopedia.
