Genome editing using programmable nucleases has revolutionized biomedical research. CRISPR-Cas9 mediated zygote genome editing enables high efficient production of knockout animals suitable for studying development and relevant human diseases. Here we report efficient disabling pancreatogenesis in pig embryos via zygotic co-delivery of Cas9 mRNA and dual sgRNAs targeting the PDX1 gene, which when combined with chimeric-competent human pluriopotent stem cells may serve as a suitable platform for the xeno-generation of human tissues and organs in pigs.

Background: The emerging incidence of pathogenic liver conditions is turning into a major concern for global health. Induction of pyroptosis in hepatocytes instigates cellular disintegration, which in turn liberates substantial quantities of pro-inflammatory intracellular substances, thereby accelerating the advancement of liver fibrosis. Consequently, directing therapeutic efforts towards inhibiting pyroptosis could potentially serve as an innovative approach in managing inflammation related chronic hepatic disorders.

Background: Selinexor is a selective inhibitor of exportin-1 (XPO1), a key mediator of the nucleocytoplasmic transport for molecules critical to tumor cell survival. Selinexor's lethality is generally associated with the induction of apoptosis, and in some cases, with autophagy-induced apoptosis. We performed this study to determine Selinexor's action in glioblastoma (GBM) cells, which are notoriously resistant to apoptosis.

Xeroderma pigmentosum group C (XPC) is a versatile protein crucial for sensing DNA damage in the global genome nucleotide excision repair (GG-NER) pathway. This pathway is vital for mammalian cells, acting as their essential approach for repairing DNA lesions stemming from interactions with environmental factors, such as exposure to ultraviolet (UV) radiation from the sun. Loss-of-function mutations in the XPC gene confer a photosensitive phenotype in XP-C patients, resulting in the accumulation of unrepaired UV-induced DNA damage.

Gene targeting (GT) is a powerful tool for manipulating endogenous genomic sequences as intended. However, its efficiency is rather low, especially in seed plants. Numerous attempts have been made to improve the efficiency of GT via the CRISPR/Cas systems in plants, but these have not been sufficiently effective to be used routinely by everyone.
