An update on CRISPR-Cas12 as a versatile tool in genome editing.

Gene editing techniques, which help in modification of any DNA sequence at ease, have revolutionized the world of Genetic engineering. Although there are other gene-editing techniques, CRISPR has emerged as the chief and most preferred tool due to its simplicity and capacity to execute effective gene editing in a wide range of organisms. Although Cas9 has widely been employed for genetic modification over the years, Cas12 systems have lately emerged as a viable option. This review primarily focuses on assessing Cas12-mediated mutagenesis and elucidating the editing efficacy of both Cpf1 (Cas12a) and C2c1 (Cas12b) systems in microbes, plants, and other species. Also, we reviewed several genetic alterations that have been performed with these Cas12 systems to improve editing efficiency. Furthermore, the experimental benefits and applications of Cas12 systems are highlighted in this study.

A Clinical Investigation on the Theragnostic Effect of MicroRNA Biomarkers for Survival Outcome in Cervical Cancer: A PRISMA-P Compliant Protocol for Systematic Review and Comprehensive Meta-Analysis.

BACKGROUND: The most often diagnosed malignancy in women worldwide is cancer of the cervix. It is also the most prevalent kind of gynecological cancer in women. This cancer originates in the opening of the cervix and spreads through sexual contact. Even though human papillomavirus (HPV) may not cause cancer immediately, it does develop over time as a result of the virus's lengthy persistence to cause dysplastic changes overtime, particularly in high-risk kinds. The primary objective of this research is to see if miRNAs are dysregulated as a result of treatment resistance in cervical cancer (CC). The aim is to see if these microRNAs may be utilized as biomarkers for detecting chemoresistance in CC, particularly for clinical applications. METHODS: The recommended protocol for comprehensive study and meta-analysis (PRISMA-P) standards will be utilized for the analysis and data interpretation. The bibliographic databases will be methodically searched using a combination of search keywords. Based on established inclusion and exclusion criteria, the acquired findings will be reviewed, and data retrieved from the selected scientific papers for systematic review. We will then construct a forest from the pooled Hazard ratio (HR) and 95% C.I. values, data obtained using the random-effects model. DISCUSSION: The focus of this study is to identify the function of miRNAs as a chemoresistance regulator and determine if they have the potential scope to be considered as biomarkers for cervical cancer. Through this systematic review and meta-analysis, the goal is to collect, compare, and analyze the data pertaining to the role of miRNAs in cervical cancer, thereby, enabling us to understand the role they play in chemosensitivity.
