In this study, we present a comprehensive peptidomic atlas of 13 maize tissues, covering both vegetative and reproductive phases. Using a three-frame translation of canonical coding sequences, we identified 6100 nonredundant endogenous peptides, significantly expanding the known plant peptide repertoire. By integrating peptidomic coexpression profiles with previously reported proteomic profiles, we found that the peptide abundance did not consistently correlate with the abundance of their source proteins, suggesting the presence of complex regulatory mechanisms. This integrated peptidomic and proteomic map can serve as a valuable resource for exploring the functional roles of endogenous peptides in maize development and facilitates the investigation of the functional relationship among genes, peptides, and proteins across various biological contexts.

Background: Prolonged exposure to LED-light has been associated with impaired sleep quality and pathogenesis of various diseases, including Alzheimer's Disease (AD). Red light therapy has been indicated as a non-invasive way of reducing anxiety, mood and sleep optimization in neurodegenerative disorders but its endogenous mechanisms are insufficiently comprehended. Hence, we assessed the effects of scheduled red-light exposure on clock genes-Bmal1 and Per 1 expression, feacal boli frequency, and anxiety-like responses in prolonged LED-light exposed rats.

Background: Cerebral amyloid angiopathy (CAA) co-occurs with neurodegeneration in Alzheimer's disease (AD). CAA is absent in many AD mouse models, rendering CAA difficult to study. Previous work has shown wild-derived WSB/EiJ (WSB) mice over-expressing APP/PS1 had increased CAA, and thus may be useful in investigating CAA-causing mechanisms.

Background: Late-onset Alzheimer's disease (LOAD) is the leading cause of dementia and a major contributor to increased mortality. Recent human datasets have revealed many LOAD genetic risk factors that are correlated with the degree of AD burden. Further, the complexity and heterogeneity of LOAD appears to be promoted by interactions between genetics and environmental factors such as diet, sedentary behavior, and exposure to toxicants, like lead (Pb), cadmium (Cd), and arsenic (As).

University of Missouri, Columbia, MO, USA.
Background: Preclinical animal models are essential for the development of effective treatments. For instance, the 5xFAD mouse model successfully represents the pathophysiology of Alzheimer's disease (AD). Expression of humanized APP (K670N/M671L - Swedish, I716V - Florida, V717I - London) and PSEN1 (M146L and L286V), found in early onset AD patients, induces the production of amyloid-β 42 (Aβ42) and amyloid deposition, gliosis, and progressive neuronal loss.

Background: Cardiovascular disease causes vascular dementia and contributes to most clinical dementia. This is embodied in the concept of vascular contributions to cognitive impairment and dementia (VCID). The potent endogenous peptide endothelin-1 (ET1) causes small artery vasoconstriction and fibrosis.
