Abstract
BACKGROUND Fat grafting is widely used in breast reconstruction and aesthetic plastic surgery. However, the success rate and effects of fat grafting, especially in elderly female donors, are observed. This study aimed to explore the difference in the survival rate of donor fat from elderly women and young women in fat grafting. METHODS We collected adipose tissue samples from two healthy Chinese women: a young woman and an elderly woman. In addition, adipose tissue samples were collected from female nude mice in four experimental groups-CON-Y, CON-O, OVX-Y, and OVX-O-after fat transplantation. Grafts were harvested, weighed, and subjected to assessment of histology and angiogenesis. RESULTS An ovariectomy model was successfully established to validate the effect of low estrogen levels on fat grafting results. Due to the influence of low estrogen levels, the graft survival rate of donor site fat was significantly higher in elderly women than in young women, accompanied by a lesser degree of angiogenesis. Low estrogen levels led to adipocyte hypertrophy, which may be related to decreased AQP-7 expression. CONCLUSIONS AQP-7 downregulation due to low estrogen levels induces adipocyte hypertrophy, and donor fat from elderly women exhibits a higher survival rate after fat transplantation.

[PMID: 37719789 PMCID: PMC10504839 DOI: 10.1177/20420188231199359] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Accepted: 08/16/2023] [Indexed: 09/19/2023] Open
Abstract
Estrogen plays a prominent role in regulating and coordinating energy homeostasis throughout the growth, development, reproduction, and aging of women. Estrogen receptors (ERs) are widely expressed in the brain and nearly all tissues of the body. Within the brain, central estrogen via ER regulates appetite and energy expenditure and maintains cell glucose metabolism, including glucose transport, aerobic glycolysis, and mitochondrial function. In the whole body, estrogen has shown beneficial effects on weight control, fat distribution, glucose and insulin resistance, and adipokine secretion. As demonstrated by multiple in vitro and in vivo studies, menopause-related decline of circulating estrogen may induce the disturbance of metabolic signals and a significant decrease in bioenergetics, which could trigger an increased incidence of late-onset Alzheimer's disease, type 2 diabetes mellitus, hypertension, and cardiovascular diseases in postmenopausal women. In this article, we have systematically reviewed the role of estrogen and ERs in body composition and lipid/glucose profile variation occurring with menopause, which may provide a better insight into the efficacy of hormone therapy in maintaining energy metabolic homeostasis and hold a clue for development of novel therapeutic approaches for target tissue diseases.

Abstract
Proton pump inhibitors (PPIs) were one of the most commonly used drugs in daily life. The adverse effects of long-term use of PPIs have aroused widespread controversy. It was of great significance to explore the molecular mechanism of sperm abnormality caused by PPIs. The PPI group was given omeprazole by gavage for 28 days. After the omeprazole intervention, the caudal epididymis was dissected to obtain sperms, and the sperm was counted through the microscope, as the acrosomal integrity was observed through PNA-FITC staining. The expression of aquaporins were detected by immunofluorescence and western blot in the testis, epididymis and spermatozoa. The liver cytochrome enzyme was evaluated by immunohistochemistry and western blot. We detected the serum estrogen level by ELISA, and the level of alanine transaminase (ALT) were detected through microplate method. The sperm count in PPI group was less than control group (p < 0.05), and the sperm acrosin integrity in PPI group was lower than control group (p < 0.05). In the testis, the expression of aquaporin 3 and aquaporin 8 in PPI group was higher than control group (p < 0.05), while the expression of aquaporin 7 was lower than control group (p < 0.05). In the epididymal and sperm, the expression of aquaporin 3 and aquaporin 7 in PPI group was higher than control group (p < 0.05), while the expression of aquaporin 8 in PPI group was lower than control group (p < 0.05). Meanwhile, the liver cytochrome enzyme in PPI group were lower than control group (p < 0.05), and estrogen and ALT in PPI group were higher than control group (p < 0.05). PPI may lead to the up-regulation of estrogen by inhibiting the activity of cytochrome enzyme, and then lead to the dysfunction of sperm parameters and acrosin integrity by affecting aquaporins function.

J Obstet Gynaecol Res 2023; 49:1173-1179.

Abstract
OBJECTIVE Redistribution of adipose tissue in the abdomen during the menopausal transition is attributable mostly to estrogen drop with aging. Adipose differentiation-related protein (ADRP), a major component of lipid droplets, is closely related to the onset of lipid accumulation. We hypothesized that estrogen exerted its tissue-specific effect in reducing abdominal fat accumulation by regulation of ADRP. METHODS Twenty-four female C57/BL6 mice aged 8 weeks were randomly divided into 3 groups: sham operation (Sham), bilateral ovariectomy (OVX), and OVX plus 17β-estradiol (OVX + E2). After being fed 8 weeks of a high-fat diet, plasma lipid profiles including total cholesterol (TC), total triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels, body weight gain, visceral, and subcutaneous adipose tissue, adipocyte size, and ADRP expression were measured. RESULTS In comparison to sham-operated mice, OVX mice presented a weight gain with higher plasma TC, TG, LDL-C levels, and lower HDL-C levels. E2 supplement ameliorated the increase in weight and lipid profiles. Elevated ADRP expression was observed in visceral adipose tissue of OVX mice, whereas treatment of estrogen suppressed the ADPR expression and reversed the fat accumulation in the abdomen. However, no significant difference of ADRP expression in subcutaneous adipose tissue was detected between sham, OVX, and OVX + E2 mice. CONCLUSIONS Our findings suggested that enhanced ADRP expression in ovariectomized mice correlates with the tissue-specific regulation of estrogen, which may provide useful clues for further exploring the regulatory mechanism and corresponding anti-abdominal obesity treatment in postmenopausal women.

Abstract
Dysregulated cell migration and invasion are hallmarks of many disease states. This dysregulated migratory behavior is influenced by the changes in expression of aquaporins (AQPs) that occur during pathogenesis, including conditions such as cancer, endometriosis, and arthritis. The ubiquitous function of AQPs in migration of diseased cells makes them a crucial target for potential therapeutics; this possibility has led to extensive research into the specific mechanisms underlying AQP-mediated diseased cell migration. The functions of AQPs depend on a diverse set of variables including cell type, AQP isoform, disease state, cell microenvironments, and even the subcellular localization of AQPs. To consolidate the considerable work that has been conducted across these numerous variables, here we summarize and review the last decade's research covering the role of AQPs in the migration and invasion of cells in diseased states.

Abstract
Obesity is one of the most important metabolic disorders of this century and is associated with a cluster of the most dangerous cardiovascular disease risk factors, such as insulin resistance and diabetes, dyslipidemia, and hypertension, collectively named Metabolic Syndrome. The role of aquaporins (AQP) in glycerol metabolism facilitating glycerol release from the adipose tissue and distribution to various tissues and organs unveils these membrane channels as important players in lipid balance and energy homeostasis and points to their involvement in a variety of pathophysiological mechanisms including insulin resistance, obesity, and diabetes. This review summarizes the physiologic role of aquaglyceroporins in glycerol metabolism and lipid homeostasis, describing their specific tissue distribution, involvement in glycerol balance, and implication in obesity and fat-related metabolic complications. The development of specify pharmacologic modulators able to regulate aquaglyceroporins expression and function, in particular AQP7 in adipose tissue, might constitute a novel approach for controlling obesity and other metabolic disorders.

Abstract
Aging is associated a decrease in thirst sensation, which makes old people more susceptible to dehydration. Dehydration produces energy metabolism alterations. Our objective was to determinate the effect of water deprivation (WD) in the lipid metabolism of old male and female rats. Here we show that in the state of WD, aging and sex alters retroperitoneal white adipose tissue (R-WAT) weight of rats, WD old female rats had more lipolysis products than old male rats, a sexual dimorphism in the hormonal response related with metabolism of the adipose tissue of old rats during WD, the expression of P-para mRNA in R-WAT did not present any alteration in animals submitted to WD, the expression of Aqp7 mRNA in R-WAT is altered by WD, age, and sex. Also, WD stimulated an increase in the plasma concentration of oxytocin and the expression of mRNA of the oxytocin receptors in R-WAT.

Abstract
Although a few aquaporins (AQPs) expressed in granulosa cells have been postulated to mediate fluid passage into the antrum, the specific expression of AQPs in different follicle cell types and stages and their roles have not been evaluated extensively. The spatiotemporal expression of aquaporin (Aqp) 7, 8, and 9 and the functional roles of Aqp9 in antral growth and ovulation were examined using a superovulation model and 3-dimensional follicle culture. Aqp9 was expressed at a high level in the rapid growth phase (24-48 h post equine chorionic gonadotropin (eCG) for superovulation induction) compared to Aqp7 (after human chorionic gonadotropin (hCG)) and Aqp8 (8-24 h post eCG and 24 h post hCG). A dramatic increase in the expression and localization of Aqp9 mRNA in theca cells was observed, as evaluated using quantitative reverse transcription-polymerase (RT-PCR) coupled with laser capture microdissection and immunohistochemistry. AQP9 was located primarily on the theca cells of the tertiary and preovulatory follicles but not on the ovulated follicles. In phloretin-treated mice, the diameter of the preovulatory follicles and the number of ovulated oocytes decreased. Consistent with these findings, knocking down Aqp9 expression with an Aqp9 siRNA inhibited follicle growth (0.28:1 = siRNA:control) and decreased the number of ovulated follicles (0.36:1 = siRNA:control) during in vitro growth and ovulation induction. Based on these results, the expression of AQPs is under the control of the physiological status, and AQP9 expression in theca during folliculogenesis is required for antral growth and ovulation in a tissue-specific and stage-dependent manner.

Abstract
RESEARCH QUESTION Fat accumulation is present in most post-menopausal women, but the underlying mechanism remains unclear. Aquaporin 7 (AQP7) is the most important glycerol channel facilitating glycerol efflux in adipocytes. High circulating FSH in post-menopausal women may play an independent role in regulation of the lipogenic effect of AQP7 in adipocytes. This study explored the role of AQP7 in the pathophysiology of post-menopausal lipogenesis mediated by high concentrations of circulating FSH. DESIGN Primary adipocytes from post-menopausal and childbearing women were analysed. An in-vivo post-menopausal animal model was established. AQP7 expression, lipid accumulation and glycerol concentration in adipocytes were measured. Luciferase reporter assay and chromatin immunoprecipitation were performed to identify transcriptional crosstalk in AQP7 promoter. RESULTS It was found that FSH down-regulated AQP7 expression and glycerol efflux function in mature adipocytes of post-menopausal women and ovariectomized (OVX) mice. In vitro, FSH inhibited lipid accumulation in primary cultured mature adipocytes in a dose-dependent manner and the mechanism was down-regulating AQP7 expression via a FSH receptor pathway. The effect of FSH on AQP7 in adipocytes was through activation of cAMP response element-binding (CREB) protein, which could bind to activator protein-1 (AP-1) sites in the AQP7 promoter, and therefore inhibited the transcriptional activation elicited by c-Jun. CONCLUSIONS Down-regulation of AQP7 by FSH mediated post-menopausal lipogenesis, and the role of FSH was based on binding competition for AP-1 sites between CREB and c-Jun.
