The causal link between capillary amyloid‑β accumulation in the brain and cerebrovascular dysfunction, previously established in the Tg‑SwDI mouse model, is to be mitigated and remains to be fully uncovered.
Spontaneous growth arrest of transformed melanocytes (resulting in benign “moles”) does not result from cell-autonomous oncogene-induced senescence, but can be explained by collective mechanisms used in normal tissue size control.
In nematode worms, NSUN-1 methylates ribosomal RNA and influences phenotypes related to aging, stress resistance, germ line development, and cuticle integrity by regulating translation of specific mRNAs.
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.
Intravital imaging with HIV-1 viral-like particle in mouse model reveals a mechanism for HIV-1 uptake by subcapsular sinus macrophages that facilitates HIV-1 spreading tofollicular dendritic and B cells.
ATAC-seq, CRISPR/Cas9 mutagenesis, reporter and gene expression assays revealed dynamic chromatin accessibility profiles governing differential gene expression during heart vs. pharyngeal muscle fate choices in the powerful chordate model Ciona.
