Single-molecule analysis of PARP1-G-quadruplex interaction.

The human genome contains numerous repetitive nucleotide sequences that display a propensity to fold into non-canonical DNA structures including G-quadruplexes (G4s). G4s have both positive and negative impacts on various aspects of nucleic acid metabolism including DNA replication, DNA repair and RNA transcription. Poly (ADP-ribose) polymerase (PARP1), an important anticancer drug target, has been recently shown to bind a subset of G4s, and to undergo auto-PARylation.

Gestational Hypertension: A Contemporary Review of Epidemiology, Pathophysiology, and Therapeutic Approaches.

Gestational hypertension and preeclampsia are frequently encountered conditions in pregnancy, often occurring around the time of delivery. Mild cases of these conditions in the near term typically result in few complications for both the mother and the newborn. However, women diagnosed with gestational hypertension or preeclampsia need careful monitoring of both maternal and fetal well-being throughout pregnancy, and those with severe symptoms should receive hospital- based management.

Brain Injury and Neurodegeneration: Molecular, Functional, and Translational Approach 2.0.

The brain is composed of different cells, such as neurons, glia, endothelial cells, etc [...

Tau filaments are tethered within brain extracellular vesicles in Alzheimer's disease.

The abnormal assembly of tau protein in neurons is a pathological hallmark of multiple neurodegenerative diseases, including Alzheimer's disease (AD). Assembled tau associates with extracellular vesicles (EVs) in the central nervous system of individuals with AD, which is linked to its clearance and prion-like propagation. However, the identities of the assembled tau species and EVs, as well as how they associate, are not known.
