Gene editing is emerging as a powerful tool for introducing novel functionalities in mushrooms. While CRISPR/Cas9-induced double-strand breaks (DSBs) typically rely on non-homologous end joining (NHEJ) for gene disruption, precise insertion of heterologous DNA in mushrooms is less explored. Here, we evaluated the efficacy of inserting donor DNAs (8-1008 bp) with or without homologous arms at Cas9-gRNA RNP-induced DSBs.

Spatially resolved transcriptomics (SRT) measures mRNA transcripts at thousands of locations within a tissue slice, revealing spatial variations in gene expression and cell types. SRT has been applied to tissue slices from multiple time points during the development of an organism. We introduce developmental spatiotemporal optimal transport (DeST-OT), a method to align spatiotemporal transcriptomics data using optimal transport (OT).

Cardiovascular diseases are a leading cause of death worldwide, and effective treatment for cardiac disease has been a research focal point. Although the development of new drugs and strategies has never ceased, the existing drug development process relies primarily on rodent models such as mice, which have significant shortcomings in predicting human responses. Therefore, human-based in vitro cardiac tissue models are considered to simulate physiological and functional characteristics more effectively, advancing disease treatment and drug development.
