CRISPR Cas9 mediated genome editing to induce apoptosis a new strategy to tackle cancer

Area of Science:

• Molecular Biology
• Genetics
• Cancer Research

Background:

• CRISPR-Cas9 is a powerful gene editing system comprising Cas9 protein and guide RNA.
• It functions by creating DNA double-strand breaks at specific sites, identified via a protospacer adjacent motif (PAM).
• DNA repair pathways, non-homologous end joining (NHEJ) and homology-directed repair (HDR), resolve these breaks.

Purpose of the Study:

• To review CRISPR-mediated apoptotic approaches for cancer treatment.
• To elucidate the mechanisms by which CRISPR-Cas9 can induce cancer cell death.
• To discuss preclinical trials, challenges, and future applications of this technology in oncology.

Main Methods:

• Literature review of CRISPR-Cas9 applications in cancer apoptosis.
• Analysis of gene editing mechanisms targeting apoptosis regulators, oncogenes, and immune checkpoints.
• Examination of preclinical data and identified challenges.

Main Results:

• CRISPR-Cas9 can effectively edit genes involved in apoptosis regulation.
• Targeting oncogenes and immune checkpoints with CRISPR-Cas9 can selectively induce cancer cell death.
• Preclinical studies demonstrate the potential of CRISPR-mediated apoptosis induction.

Conclusions:

• CRISPR-Cas9 offers a promising strategy for cancer therapy by manipulating apoptotic pathways.
• Further research and preclinical validation are crucial for clinical translation.
• CRISPR-mediated apoptosis holds significant potential for future cancer treatment modalities.
