Ribonucleoprotein (RNP) complexes can form multiple mesoscale assemblies, including stress granules (SGs). However, the function and regulation of the soluble RNP complexes are not fully understood. A recent study by Boraas et al. showed that G3BP1, a key node in SG formation, forms focal adhesion (FA)-localized RNP complexes and regulates cell migration.

Existing research has proven difficult to understand the interplay between upstream signaling events during NLRP3 inflammasome activation. Additionally, events downstream of inflammasome complex formation such as cytokine release and pyroptosis can exhibit variation, further complicating matters. Cell Painting has emerged as a prominent tool for unbiased evaluation of the effect of perturbations on cell morphological phenotypes.

CRISPR/Cas9 genome editing technology has revolutionized plant breeding by offering precise and rapid modifications. Traditional breeding methods are often slow and imprecise, whereas CRISPR/Cas9 allows for targeted genetic improvements. Previously, direct delivery of Cas9-single guide RNA (sgRNA) ribonucleoprotein (RNP) complexes to grapevine () protoplasts has been demonstrated, but successful regeneration of edited protoplasts into whole plants has not been achieved.

In 1972, mixed connective tissue disease (MCTD) was proposed by Sharp et al. as a disease entity characterized by overlapping clinical features of systemic lupus erythematosus, systemic sclerosis (SSc), and polymyositis, as well as high titers of serum anti-U1-RNP antibody. However, the disease concept of MCTD is sometimes far from being sufficiently acknowledged.

CRISPR-Cas9 gene editing has become an important tool for the study of plant pathogens, allowing researchers to functionally characterize specific genes involved in phytopathogenicity, virulence, and fungicide resistance. Protocols for CRISPR-Cas9 gene editing have already been developed for Phytophthoras, an important group of oomycete plant pathogens; however, these efforts have exclusively focused on agricultural pathosystems, with research lacking for forest pathosystems. We sought to develop CRISPR-Cas9 gene editing in two forest pathogenic Phytophthoras, and , using a plasmid-ribonucleoprotein (RNP) co-transformation approach.

Mice carrying patient-associated base changes are powerful tools to define the causality of single-nucleotide variants to disease states. Epitope tags enable immuno-based studies of genes for which no antibodies are available. These alleles enable detailed and precise developmental, mechanistic, and translational research.
