Designing an effective single-guide RNA (sgRNA) is crucial for the success of CRISPR-based genome editing. Poorly designed sgRNAs can result in low editing efficiency or unintended off-target effects. To optimize sgRNA performance, the following factors should be considered: 

Single-guide RNA (sgRNA) is an essential element of CRISPR-based genome editing therapies. While sgRNA itself is not a standalone drug, it plays a pivotal role in directing Cas proteins to specific genetic sequences for precise editing. Several sgRNA-based pipelines have entered clinical trials, primarily targeting genetic disorders and certain complex diseases. 

Single-guide RNA (sgRNA) has emerged as a pivotal tool in CRISPR-based genome editing, facilitating precise and programmable modifications of DNA or RNA. As part of CRISPR-Cas systems, sgRNA plays a central role in directing Cas proteins to specific genomic loci. Its therapeutic applications have progressed significantly, with notable advancements in treating genetic diseases, cancers, and infectious diseases. 

Antisense oligonucleotide (ASO) drugs have shown significant progress in clinical development, targeting a wide range of diseases, from rare genetic disorders to more common conditions. Since the approval of the first ASO drug, Fomivirsen, in 1998, the pipeline has expanded substantially. Here are some key ASO drugs currently in clinical stages: 

Antisense oligonucleotides (ASOs) and small interfering RNAs (siRNAs) are both tools for modulating gene expression, but they differ in structure, mechanism, delivery, and applications. ASOs are single-stranded molecules designed to bind target RNA and alter its function, while siRNAs are double-stranded molecules that trigger RNA interference (RNAi) to degrade target mRNA. Below is a detailed comparison.
