Article Abstract
Introduction: Feline infectious peritonitis (FIP), caused by feline coronavirus (FCoV), is a highly lethal disease characterized by systemic organ infection in cats. Current challenges of FIP include the absence of definitive diagnostic criteria, effective vaccines, and targeted therapies. Developing a robust genome editing toolkit is therefore critical to unraveling FCoV replication and pathogenesis mechanisms, elucidating viral protein functions, and identifying promising diagnostic and therapeutic targets.
Methods: In this study, we developed a yeast-based CRISPR genome editing system compatible with a TAR-generated FCoV infectious clone, enabling gene deletion, gene insertion, and point mutation with high efficiencies and accuracies.
Results And Discussion: This system not only will contribute to a better understanding of the pathogenic mechanisms of FCoV but also serves as a valuable platform for vaccine development. Furthermore, it offers a possible strategy for genome editing and reverse genetics for other coronaviruses.

The GM2 gangliosidoses are lysosomal storage disorders exhibiting a spectrum of neurological phenotypes ranging from childhood death to debilitating adult-onset neurological impairment. To date, no mouse model harbouring a specific human mutation causing GM2 gangliosidosis has been created. We used CRISPR/Cas9 to generate knockin (KI) mice with the common adult-onset Hexa Gly269Ser variant as well as knockout (KO) mice with Hexa mutations expected to cause complete HexA deficiency.

The sterile insect technique (SIT) is a highly effective biologically-based method for the suppression of many insect pest populations. SIT efficacy could be improved by methods of male sterilization that avoid the use of irradiation that can result in diminished fitness and mating competitiveness. Alternative sterilization methods include conditional disruption of genes for male fertility, or using their sperm-specific promoters to drive the expression of genes for lethal effectors.

In addition to being one of the primary processes for the formation and expansion of gene families, gene duplication also establishes the basis for the diversity and redundancy of gene functions, providing an abundance of genetic resources and a potent adaptive potential for biological evolution. Trehalose is a high-quality carbon source and blood sugar in insects. However, recent theoretical developments suggest that mechanisms for facilitated trehalose transport in lepidopteran insects remain relatively scarce.

Gene therapy has revolutionized the therapeutic landscape for hemophilia A and B, offering the prospect for persistent endogenous production of coagulation factors VIII and IX. Recent advances in adeno-associated virus (AAV)-mediated gene transfer, particularly the approvals of valoctocogene roxaparvovec (Roctavian) and etranacogene dezaparvovec (Hemgenix), mark significant milestones in hemophilia care. This mini-review synthesizes emerging clinical data from phase I-III trials published between 2022 and 2025, emphasizing efficacy, durability, and immunogenicity profiles of leading AAV-based therapies.

Advances in genome engineering have paved the way for targeted epigenome engineering, providing fundamental insights into the role of epigenetic modifications in trait inheritance. Engineered epialleles have already delivered stable, heritable changes in agronomic traits. Despite this capacity, progress in the field has not yet achieved its potential, leaving many avenues of research unexplored.
