Article Abstract

Abiotic stresses in plants such as salinity, drought, heavy metal toxicity, heat, and nutrients limitations significantly reduce agricultural production worldwide. The genome editing techniques such as transcriptional activator-like effector nucleases (TALENs) and zinc finger nucleases (ZFNs) have been used for genome manipulations in plants. However, clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) technique has recently emerged as a promising tool for genome editing in plants to acquire desirable traits. The CRISPR/Cas9 system has a great potential to develop crop varieties with improved tolerance against abiotic stresses. This review is centered on the biology and potential application of the CRISPR/Cas9 system to improve abiotic stress tolerance in plants. Furthermore, this review highlighted the recent advancements of CRISPR/Cas9-mediated genome editing for sustainable agriculture.

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.

Acute myeloid leukemia (AML) represents a genetically heterogeneous malignancy, with mutations in the nucleophosmin-1 (NPM1) gene identified as the most prevalent and clinically significant molecular biomarkers. These mutations play a crucial pivotal role in the realms of diagnosis, prognosis, and therapeutic decision-making. Although an ideal measurable residual disease (MRD) test has yet to be developed, there is increasing acknowledgment of the significance of advanced molecular methodologies for monitoring MRD in NPM1-mutated (NPM1) AML.

Calcium (Ca)/calmodulin (CaM)-dependent protein kinase II (CaMKII) is an emerging drug target for age-related diseases. It is a multifunctional kinase with complex activation modes, numerous isoforms, broad tissue distribution, and a dual role in health and disease. In particular, its isoforms share a high degree of conservation within the catalytic and regulatory domains, with only minor differences confined to the linker region.

Syncytiotrophoblasts (STBs) constitute one of the core components of the placenta, responsible for synthesizing pregnancy-sustaining hormones such as human chorionic gonadotropin (HCG). Deficient syncytialization of cytotrophoblasts affects the hormonal secretion and placental development, contributing to pregnancy-associated disorders, including spontaneous miscarriage. To date, the molecular mechanisms, particularly the role of transcription factors (TFs), in STB lineage specification remain incompletely understood.

In yeast, mitochondrial fission is mediated by the dynamin-like GTPase Dnm1, which is recruited to the mitochondrial outer membrane by its receptor, Fis1. To investigate the spatial distribution of Fis1, we used the CRISPR-Cas9 system to insert the gene fragment encoding mNeonGreen into the gene for its N-terminal tagging. Fluorescence microscopy revealed that mNeonGreen-Fis1 appeared as discrete puncta on mitochondria, in addition to a diffuse signal.
