Abstract:
Recent advances in the treatment of metastatic melanoma have emerged only from advances in our understanding of melanoma development and progression at the cellular and molecular levels. Despite the impact that such advances have made on the clinical management of this cancer over the last decade, additional insights into factors that promote melanoma progression and therapeutic resistance are needed to combat this disease. CRISPR-Cas9 gene editing technology is a powerful tool for studying gene function in a timely and cost-effective manner, enabling the manipulation of specific DNA sequences via a targeted approach. Herein, we describe a protocol for generating functional gene knockouts in melanoma cell lines by CRISPR-Cas9 gene editing, and we present an example application of this protocol for the successful knockout of the Foxc2 transcription factor-encoding gene in the B16-F1 murine melanoma cell line.
Insights
Researchers developed a CRISPR-Cas9 gene editing protocol to create gene knockouts in melanoma cells. This method successfully inactivated the Foxc2 gene in a murine melanoma cell line, aiding cancer research.
