CRISPRi-based Circuits to Control Gene Expression in Plants

CRISPRi-based Circuits to Control Gene Expression in Plants

Academic Background In the field of plant biotechnology, traditional gene manipulation methods focus on producing the desired phenotypes and cellular activities through continuous transgene expression. However, strong continuous promoters may lead to gene silencing, metabolic burdens, or other adverse effects on yield, preventing the full realizati...

Development of Multiplexed Orthogonal Base Editor (MOBE) Systems

In recent years, with the rapid development of gene editing tools, especially the introduction of the CRISPR-Cas9 system, it has become possible to precisely modify specific DNA sequences. Currently, the introduction of single-nucleotide variants (SNVs) as a powerful tool for studying gene function and disease associations is particularly important...

Complete Substitution with Modified Nucleotides in Self-Amplifying RNA Suppresses the Interferon Response and Increases Potency

Introduction Under the influence of the COVID-19 pandemic, mRNA vaccine technology has made significant advances. However, its short half-life and high dosage requirements have led to side effects and accessibility issues. To overcome these challenges, self-amplifying RNA (saRNA) has become a research hotspot. saRNA utilizes RNA-dependent RNA polym...

In Vivo AAV-SB-CRISPR Screens of Tumor-Infiltrating Primary NK Cells Identify Genetic Checkpoints of CAR-NK Therapy

AAV-SB-CRISPR Screening Identifies Genetic Checkpoints in Tumor-Infiltrating Primary Natural Killer Cells for CAR-NK Therapy With the rapid advancement of biotechnology and gene editing technologies, increasing attention is being paid to enhancing the clinical potential of natural killer (NK) cells in cancer therapy. Despite their potential in clin...

Programming Tumor Evolution with Selection Gene Drives to Proactively Combat Drug Resistance

Engineering Selective Gene Drives to Steer Tumor Evolution to Counteract Drug Resistance As tumors evolve, targeted therapies against cancer often fail due to the evolution of drug resistance. This study demonstrates a way to manipulate tumor evolution repeatedly to design therapeutic opportunities, even in the presence of genetic heterogeneity. We...
