This analytical modality also permits the direct observations of dynamic movements of TET such as sliding and interstrand transfer by high-speed AFM. In addition, the thymine DNA glycosylase-mediated base excision repair process was characterized in the DNA nanochip. Thus, we have convincingly established the system's ability to physically regulate enzymatic reactions, which could prove useful for the observation and characterization of coordinated DNA demethylation processes at the nanoscale. © The Author(s) 2020. Published by Oxford University Press on behalf of Nucleic Acids Research.The brain's relationship to essential hypertension is primarily understood to be that of an end-organ, damaged late in life by stroke or dementia. Emerging evidence, however, shows that heightened blood pressure (BP) early in life and prior to traditionally defined hypertension, relates to altered brain structure, cerebrovascular function, and cognitive processing. Deficits in cognitive function, cerebral blood flow (CBF) responsivity, volumes of brain areas, and white matter integrity all relate to increased but pre-hypertensive levels of BP. Such relationships may be observed as early as childhood. In this review, we consider the basis of these relationships by examining the emergence of putative causative factors for hypertension that would impact or involve brain function/structure, e.g., sympathetic nervous system activation and related endocrine and inflammatory activation. Currently, however, available evidence is not sufficient to fully explain the specific pattern of brain deficits related to heightened BP. Despite this uncertainty, the evidence reviewed suggests the value that early intervention may have, not only for reducing BP, but also for main
