CRISPR knockout of UBASH3B suppresses malignant melanoma cell growth 3282

Abstract Description Skin cancer remains a significant health concern, affecting approximately 1 in 5 Americans over their lifetime. In 2024 alone, an estimated 100,640 new cases are projected, contributing to roughly 5% of all cancer diagnoses. While malignant melanoma accounts for a smaller proportion of cases, its aggressive nature and high metastatic potential make it particularly challenging to manage. This study investigates the potential of UBASH3B gene knockout as a therapeutic strategy to inhibit tumor growth and metastasis. UBASH3B has emerged as a critical regulator of cancer progression, with its expression linked to enhanced tumor cell invasion and dissemination. Using CRISPR-Cas9-mediated gene knockout in A375 melanoma cells, UBASH3B was effectively silenced. Knockout efficacy was validated using an indel detection assay to confirm CRISPR-induced mutations at the target site, followed by real-time PCR to confirm minimal to no UBASH3B expression post-knockout. These findings support UBASH3B as a promising therapeutic target for inhibiting melanoma progression and warrant further investigation across other cancer types.
