Mar 24, 2022 · In this review, we have discussed the potential role of CRISPR/Cas9 and NGS in the advancement of personalized cancer medicine. Personalized medicine Personalized or precision medicine aims in developing the treatment procedure tailored to the individual and eliminate the constraints of “one-size-fits-all” therapy [ 11 , 12 , 13 ].
Mar 24, 2022 · Fig. 1 Represents the application of Next Generation Sequencing (NGS) and CRISPR/Cas9 in personalised medicine: A Cancer can be diagnosed. without non-invasive biopsy samples with the help of ...
- The evolution of CRISPR tools that have been harnessed in the investigation of cancer biology. Since the inception of CRISPR-associated 9 (Cas9) gene editing in mammalian cells, there has been a rapid expansion in the field of CRISPR technology.
- Different workflows used in CRISPR screening and mutagenesis. The CRISPR screening procedures commence by selecting the appropriate screening system, offering various options: A CRISPRko, where Cas9 is employed to disrupt genes, resulting in the generation of premature stop codons or frameshift mutations; CRISPRa, involving the attachment of activation domains (e.g., VPR, VP64) to dCas9, resulting in enhanced transcription of target genes; CRISPRi, on the contrary, employs repression domains (e.g., KRAB) tethered to dCas9, leading to a reduction in the transcription of target genes; Base editing screen, which uses a base editor (e.g., cytosine deaminase or adenine deaminase) with or without a uracil DNA glycosylase inhibitor to induce mutations without causing double-strand breaks.
- The various mechanisms employed for gene editing. In the first part (a), Zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and CRISPR-Cas systems are capable of generating double-strand breaks (DSBs) at precise locations within the genome.
- The diverse applications of CRISPR technology within cancer research. In section a, the paragraph explains that the inhibition of a specific gene can be accomplished by combining Deactivated Cas9 (dCas9) with repressor domains.
The goal is no longer to match the treatment for the diagnosed tumor but rather to build a treatment method that fits the tumor exactly, and the potential role of CRISPR/Cas9 and NGS is discussed in advancing personalized medicine. Background Cancer is caused by a combination of genetic and epigenetic abnormalities. Current cancer therapies are limited due to the complexity of their mechanism ...
