A lack of effective drugs and technical means to eradicate hepatitis B virus (HBV) is a bottleneck that limits the ability to fully cure HBV infection. Recently, genome-editing technology based on clustered regularly interspaced short palindromic repeats -associated protein 9 is an emerging technique for editing specific gene loci, which can specifically target HBV covalently closed circular DNA, effectively inhibits HBV DNA replication and regulates HBV functional protein expression, and is expected to become a powerful gene therapy tool for the complete eradication of HBV. Considering this, it has become the focus of attention for scholars at home and abroad that how to use clustered regularly interspaced short palindromic repeats -associated protein 9 to accomplish modification of HBV genomes for complete eradication of HBV. This paper summarizes the latest progress based on the latest research results at home and abroad in the application of clustered regularly interspaced short palindromic repeats -associated protein 9 gene editing technology in anti-HBV infection treatment, and expounds its potential and challenges as a radical cure for HBV infection.

Background: Leishmaniasis is a health problem in many regions with poor health and poor life resources. According to the World Health Organization (WHO), an estimated 700,000-1 million new cases arise annually. Effective control of sand fly vector populations is crucial for reducing the transmission of this disease.

The presence of the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas system in the superbug presents a unique opportunity to precisely target and edit bacterial genomes to modify their drug resistance. The objective was to detect the prevalence of CRISPR in extensively and pan-drug-resistant and to determine the utility of whole-genome sequencing (WGS) for the analysis of the entire genome for such strains. The antimicrobial susceptibilities of one hundred isolates were assessed using the antibiotic susceptibility test (AST) card of the VITEK system.

Rice grain size influences both grain yield and quality, making it a significant target for rice genetic improvement. In recent years, numerous genes related to grain size with differential effects have been cloned. The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) gene editing system is a convenient tool for modifying genes.

Genome-wide functional genetic screening has been widely used in the biomedicine field, which makes it possible to find a needle in a haystack at the genetic level. In cancer research, gene mutations are closely related to tumor development, metastasis, and recurrence, and the use of state-of-the-art powerful screening technologies, such as clustered regularly interspaced short palindromic repeat (CRISPR), to search for the most critical genes or coding products provides us with a new possibility to further refine the cancer mapping and provide new possibilities for the treatment of cancer patients. The use of CRISPR screening for the most critical genes or coding products has further refined the cancer atlas and provided new possibilities for the treatment of cancer patients.

Background: α thalassemia/mental retardation syndrome X-linked (ATRX) serves as a part of the sucrose nonfermenting 2 (SNF2) chromatin-remodeling complex. In interphase, ATRX localizes to pericentromeric heterochromatin, contributing to DNA double-strand break repair, DNA replication, and telomere maintenance. During mitosis, most ATRX proteins are removed from chromosomal arms, leaving a pool near the centromere region in mammalian cells, which is critical for accurate chromosome congression and sister chromatid cohesion protection.
