This study aimed to determine whether variations in cardiometabolic health, both prior to and resulting from different estradiol treatment regimens, are related to the ability of estradiol to improve the cognitive aging trajectory in ovariectomized Long-Evans rats. Cognitive function and health status were assessed at 10 months of age after which rats were ovariectomized and administered vehicle or various estradiol treatments. Rats were assessed again at 18 (middle age) and 22 (old age) months. Cognition was evaluated using a spatial memory radial-maze task. Health status was determined through body composition analysis (dual-energy X-ray absorptiometry), glucose tolerance testing, and blood pressure and heart rate measurements (tail-cuff plethysmography). Results demonstrated that both continuous ongoing estradiol treatment and a previous 40-day estradiol exposure (terminated long before testing) significantly improved the cognitive aging trajectory from middle to old age. However, only continuous estradiol treatment had positive impacts on health measures; previous estradiol treatment provided no benefits to aging cardiometabolic systems. In contrast, a delayed estradiol treatment (initiated months after ovariectomy) provided no benefits for cognition but provided health benefits.

Based on genetic downregulation of ATGL in β cells, multiple mechanisms are proposed that acutely or chronically regulate insulin secretion. Currently, the contribution of acute vs chronic mechanisms in the regulation of insulin secretion is unclear. Also, little is known whether ATGL affects α-cell function. Using the human-specific ATGL inhibitor, NG497, this study investigates the impact of acute inhibition of ATGL on hormone secretion from human islets. In addition, morphological differences in LDs were assessed in confocal images of β and α cells. β cells exposed to NG497 overnight showed notable increases in LD size and number under glucose-sufficient culture. The effect of NG497 on LD accumulation in α cells was more prominent under fasting-simulated conditions than glucose-sufficient conditions, pointing toward a critical role for ATGL lipolysis under conditions that stimulate hormone secretion in β and α cells. When exposed to NG497 acutely, human islets reduced glucose-stimulated insulin secretion mildly, particularly first-phase insulin secretion, to an extent somewhat less pronounced than the impacts of chronic ATGL downregulation. Thus, chronic mechanisms may play a predominant role in reducing insulin secretion when ATGL is downregulated.

Accordingly, understanding the cellular basis of T3 action requires identification of Dio3-expressing cell types but this is difficult because of low level, transient expression within the complexity of the nervous system. Here, we derived a knock-in Dio3Cre driver that sensitively labels Dio3-expressing cells in male and female mice. In this anatomical study, we identified Dio3 expression in the immature amygdala and other brain regions associated with emotion and motivation, and in serotonergic raphe nuclei, which influence many behavioral and physiological systems. Notably, expression in circumventricular organs, including the chemosensory subfornical organ and organum vasculosum laminae terminalis, suggested regulation of centers that lack a blood-brain barrier and directly sense signaling factors in the circulation. Expression in trigeminal, dorsal root, cochleovestibular, and other sensory ganglia highlighted contributions to sensory pathways. Although Dio3 expression declines during maturation, a conditional Dio3CreERt2 driver revealed neurons with T3-inducible expression in the adult brain, suggesting ongoing homeostatic functions.

To be activated, SIKs require phosphorylation in the catalytic kinase domain by liver kinase B1. In response to extracellular stimulations, their activity can be further regulated through phosphorylation by protein kinase A (PKA), and Ca2+/calmodulin-dependent protein kinases. PKA-mediated SIK inhibition is a major link between G-protein coupled receptor activation and the target gene transcription program. All 3 SIK isoforms-SIK1, SIK2, and SIK3-are expressed in adipocytes, with SIK2 being the most abundant in both rodents and humans. SIKs play essential roles in maintaining adipose tissue homeostasis by regulating physiological processes involving insulin signaling, glucose uptake, lipogenesis, and thermogenesis. Each SIK isoform could play both redundant and unique roles in these physiological processes. Many of the substrates that mediate their physiological functions in adipocytes have been characterized, and downstream mechanisms of action have also been proposed. However, due to the functional redundancy of SIKs, a major challenge is to delineate their isoform-specific roles in adipose tissue in vivo using genetic mouse models. In addition, common genetic variants and rare mutations in the SIK genes have been identified to be associated with metabolic, cardiovascular, and developmental conditions, suggesting a translational implication for human disease that deserves investigation.
