    Challenges in Preventing Off-Target Effects in Cancer Treatment

    Introduction

    The advent of CRISPR gene editing has revolutionized biomedical research and cancer treatment, offering unprecedented precision in genetic modifications. However, a critical challenge persists—preventing off-target effects, which can undermine therapeutic efficacy and safety. Off-target effects occur when the CRISPR-Cas9 system unintentionally edits genes other than the intended target, potentially leading to adverse consequences in cancer therapies. Understanding and overcoming these challenges is essential for advancing CRISPR gene editing to enhance its reliability and application in oncology.
