    Description

    Previous studies showed an abundance of functional Connexin43 (Cx43) hemichannels consequent to loss of plakophilin-2 (PKP2) expression in adult murine hearts. This study combined pre-embedding immunolabeling with serial block-face scanning electron microscopy (SBF-SEM) to visualize and examine the gap junction plaque morphology. They used a murine model of cardiomyocyte-specific Tamoxifen (TAM) activated...

    Description

    Long interspersed element-1 (LINE-1) is an autonomously active retrotransposon in the human genome. The LINE-1 mRNA encodes two proteins, ORF1p and ORF2p, which are essential for retrotransposition. This study showed that electrostatic interactions and trimer conformational dynamics together tune the properties of ORF1p assemblies to allow for efficient LINE-1 ribonucleoprotein complex formation in...
