Using a chemical model (4-vinylcyclohexene diepoxide; VCD) of accelerated ovarian failure, we previously demonstrated that menopausal females are more susceptible to CVD compared with peri- or premenopausal females like humans. Yet, the cellular and molecular mechanisms underlying this shift in CVD susceptibility across the pre- to peri- to menopause continuum remain understudied. In this work using the VCD mouse model, we phenotyped cellular and molecular signatures from hearts at each hormonally distinct stage that included transcriptomic, proteomic, and cell biological analyses. The transcriptional profile of premenopausal hearts clustered separately from perimenopausal and menopausal hearts, which clustered more similarly. Proteomics also revealed hormonal clustering; perimenopausal hearts grouped more closely with premenopausal than menopausal hearts. Both proteomes and transcriptomes showed similar trends in genes associated with atherothrombosis, contractility, and impaired nuclear signaling between pre-, peri-, and menopausal murine hearts. Further analysis of posttranslational modifications (PTMs) showed hormone-dependent shifts in the phosphoproteome and acetylome. To further interrogate these findings, we triggered pathological remodeling using angiotensin II (Ang II). Phosphorylation of AMP-activated protein kinase (AMPK) signaling and histone deacetylase (HDAC) activity were found to be dependent on hormonal status and Ang II stimulation. Finally, knockdown of anti-inflammatory regulatory T cells (Treg) exacerbated Ang II-dependent fibrosis implicating HDAC-mediated epigenetic suppression of Treg activity. Taken together, we demonstrated unique cellular and molecular profiles underlying the cardiac phenotype of pre-, peri-, and menopausal mice supporting the necessity to study CVD in females across the hormonal transition.<b>NEW & NOTEWORTHY</b> Cycling and perimenopausal females are protected from cardiovascular disease (CVD) whereas menopausal females are more susceptible to CVD and other pathological sequalae.

Sleep is also a homeostatic process, with the need to sleep increasing as a function of being awake. Acute sleep deprivation (SD) increases sleep need, and subsequent recovery sleep (RS) discharges it. SD is known to alter brain gene expression in rodents, but it remains unclear which changes are linked to sleep homeostasis. To investigate this question, we analyzed RNA-seq data from adult male mice subjected to 3 and 5-6 h of SD and 2 and 6 h of subsequent RS. We hypothesized that molecular changes associated with sleep homeostasis would mirror sleep pressure dynamics as defined by brain electrical activity, peaking at 5-6 h of SD and no longer differentially expressed after 2 h of RS. We report that 5-6 h of SD produces the largest effect on gene expression, and the majority of differentially expressed genes normalize after 2 h of RS. These genes are involved in cellular redox homeostasis, DNA damage/repair, and chromatin regulation and may underlie the molecular basis of sleep homeostasis. Genes associated with cellular stress do not normalize within 6 h of RS and may underlie non-sleep-specific effects of SD. In addition, RS affects gene expression related to energy metabolism and Wnt-signaling, potentially contributing to its restorative effects. Finally, our study also points to the regulation of expression of a subset of circadian transcription factors as a function of sleep need. Overall, our results offer novel insights into the molecular mechanisms underlying sleep homeostasis and the broader effects of SD.<b>NEW & NOTEWORTHY</b> This study investigates different time points of sleep deprivation and recovery sleep to better understand the molecular processes influenced by sleep and lack of sleep.

We aimed to investigate the acute effects on coagulation- and cardiovascular factors immediately after a 2-h NMES session. Levels of overall hemostatic potential (OHP), fibrinogen, factor VIII, and Olink proteomic cardiovascular factors were assessed before and after the NMES session in 36 healthy participants (20 males and 16 females) with a mean age of 31.9 yr. NMES was administered using integrated textile electrodes in pants (NMES pants). Mean intensities during the quadriceps, hamstrings, and gluteus muscle stimulation were 16.5, 20.5, and 25.4 mA, respectively, corresponding to submaximal intensity levels with acceptable discomfort (just below 4 on the visual analogue scale [VAS], 0-10). The NMES session resulted in a significant increase in mean (SD) OHP [94.4 (28.3) to 103 (31.0)], and overall coagulation potential [292 (50.4) to 307(49.8)], and a decrease in overall fibrinolytic potential [68.2 (5.46) to 67.1 (5.20)]. These changes were highly correlated with the increase in fibrinogen (all <i>R</i> > 0.7, <i>P</i> ≤ 0.001), but not with the increase in factor VIII. In addition, 18 of 92 cardiovascular proteins, specifically those involved in regulating inflammation and extracellular matrix remodeling, were influenced by NMES; however, low correlations were found between the changes in these proteins and OHP analyses. In conclusion, the NMES session resulted in a slight increase in the coagulative state, mirroring that seen after a bout of regular exercise. The changes observed in cardiovascular factors, which are mostly not directly related to coagulation, suggest that NMES may subsequently modulate inflammatory responses, warranting further investigation.<b>NEW & NOTEWORTHY</b> The immediate response to a 2-h neuromuscular electrical stimulation (NMES) session, delivered at an acceptable level of discomfort using NMES-pants, marginally increases the coagulative state, similar to what is observed after regular physical exercise. This change is not expected to significantly increase the risk of blood clotting, as all factors remain within the normal reference range.
