RpH-ILV: Probe for lysosomal pH and acute LLOMe-induced membrane permeabilization in cell lines and .

Lysosomal pH dysregulation is a critical element of the pathophysiology of neurodegenerative diseases, cancers, and lysosomal storage disorders (LSDs). To study the role of lysosomes in pathophysiology, probes to analyze lysosomal size, positioning, and pH are indispensable tools. Here, we developed and characterized a ratiometric genetically encoded lysosomal pH probe, RpH-ILV, targeted to a subpopulation of lysosomal intraluminal vesicles.

The type III secretion chaperone SctY may shield the hydrophobic export gate-binding C-terminus of its substrate SctX.

Gram-negative bacteria such as Aeromonas and Yersinia spp. have developed mechanisms to inhibit the immune defense of their host. Effector proteins are directly injected into the host cytoplasm from the bacterial cytosol via type III secretion systems (T3SSs), where they modulate the cytoskeleton and signaling of the cell.

A detailed protocol for expression, purification, and activity determination of recombinant SaCas9.

Recombinant SaCas9 is useful for a broad range of applications in the context of genome editing, especially when the specific protospacer adjacent motifs of other Cas9 derivatives are missing. Here, we describe a detailed protocol for the expression and purification of recombinant SaCas9. We detail the main steps for immobilized metal affinity chromatography and size exclusion chromatography.

The Desmin Mutation -c.735G>C Causes Severe Restrictive Cardiomyopathy by Inducing In-Frame Skipping of Exon-3.

Currently, little is known about the genetic background of restrictive cardiomyopathy (RCM). Herein, we screened an index patient with RCM in combination with atrial fibrillation using a next generation sequencing (NGS) approach and identified the heterozygous mutation -c.735G>C.
