Morphologic, molecular, biomechanical and computational analyses show that the specialized extracellular matrix architecture of the umbilical artery contributes to its rapid closure at birth and regulates smooth muscle cell differentiation.
Although puromycin staining is often used to examine subcellular translation, puromycin-labeled proteins are rapidly released from ribosomes even in the presence of elongation inhibitors, which may confound translation site localization.
Malaria pre-exposed volunteers exhibit large breadth of humoral immune responses, with strong variation between individuals, which might compromise vaccine-induced humoral immune response due to natural imprinting.
In-planta ancestral protein resurrection of the female determinant of self-incompatibility specificity in Arabidopsis halleri demonstrates that two allelic variants currently segregating as distinct receptor-ligand combinations diverged through an asymmetrical process.
A muscle-derived signaling molecule suppresses excessive accumulation of lipids in the Drosophila adipose tissue by activating the Pi3K/Akt/mTOR signaling cascade in the Drosophila hepatocyte-like cells.
