Abstract
Ovarian aging, a natural process in women and various other female mammals as they age, is characterized by a decline in ovarian function and fertility due to a reduction in oocyte reserve and quality. This phenomenon is believed to result from a combination of genetic, hormonal, and environmental factors. While these factors collectively contribute to the shaping of ovarian aging, the substantial impact and intricate interplay of chronic inflammation in this process have been somewhat overlooked in discussions. Chronic inflammation, a prolonged and sustained inflammatory response persisting over an extended period, can exert detrimental effects on tissues and organs. This review delves into the novel hallmark of aging-chronic inflammation-to further emphasize the primary characteristics of ovarian aging. It endeavors to explore not only the clinical symptoms but also the underlying mechanisms associated with this complex process. By shining a spotlight on chronic inflammation, the aim is to broaden our understanding of the multifaceted aspects of ovarian aging and its potential clinical implications.

Disulfiram Improves Fat Graft Retention by Modulating Macrophage Polarization With Inhibition of NLRP3 Inflammasome-Mediated Pyroptosis. Aesthet Surg J 2024; 44:NP501-NP518. [PMID: 38567442 PMCID: PMC11177556 DOI: 10.1093/asj/sjae075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2024] [Revised: 03/26/2024] [Accepted: 03/26/2024] [Indexed: 04/04/2024] Open
Abstract
BACKGROUND Macrophage-mediated inflammatory response in the early post-grafting period restricts fat graft retention. Pyroptosis is a novel type of programmed cell death that extensively participates in inflammatory pathologies. OBJECTIVES This study sought to determine whether macrophage pyroptosis was activated during the inflammatory phase after fat grafting and to investigate the efficacy of a pyroptosis inhibitor, disulfiram (DSF), in fat graft retention. METHODS We established a C57BL/6 mice fat grafting model and then analyzed macrophage pyroptosis. DSF (50 mg/kg, every other day) was intraperitoneally injected starting 1 hour before fat grafting and continued for 14 days. An in vitro co-culture system was established in which mouse RAW264.7 macrophages were co-cultured with apoptotic adipocytes to further validate the findings of the in vivo studies and to explore the underlying mechanisms. RESULTS Here we reported that macrophage pyroptosis was activated in both fat grafts and in vitro co-culture models. DSF was found to be a potent pyroptosis inhibitor, promoting M2 macrophage polarization. In addition, DSF was demonstrated to enhance vascularization and graft retention. CONCLUSIONS Our results suggested that pyroptosis plays a crucial role in the inflammatory cascade within fat grafts. DSF, being a clinically available drug, could be translated into a clinically effective drug for improving fat graft survival by inhibiting macrophage pyroptosis, therefore inducing M2 macrophage polarization and promoting neovascularization.

Reproductive and transgenerational toxicity of bisphenol S exposure in pregnant rats: Insights into hormonal imbalance and steroid biosynthesis pathway disruption. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 927:172379. [PMID: 38614345 DOI: 10.1016/j.scitotenv.2024.172379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 03/23/2024] [Accepted: 04/08/2024] [Indexed: 04/15/2024]
Abstract
Bisphenol S (BPS) is an alternative chemical to bisphenol A commonly used in food packaging materials. It raises concerns due to potential adverse effects on human health. However, limited evidence exists regarding reproductive toxicity from BPS exposure, and the mechanism of associated transgenerational toxicity remains unclear. In this study, pregnant SD rats were exposed to two different doses of BPS (0.05 or 20 mg/kg) from GD6 to PND21. The objective was to investigate reproductive and transmissible toxicity induced by BPS, explore endocrine effects, and uncover potential underlying mechanisms in rats. Perinatal exposure to BPS in the F0 generation significantly decreased the rate of body weight, ovarian organ coefficient, and growth and development of the F1 generation. Notably, these changes included abnormal increases in body weight and length, estrous cycle disruption, and embryonic dysplasia in F1. 4D-DIA proteomic and PRM analyses revealed that exposure to 20 mg/kg group significantly altered the expression of proteins, such as Lhcgr and Akr1c3, within the steroid biosynthetic pathway. This led to elevated levels of FSH and LH in the blood. The hypothalamic-pituitary-ovarian (HPO) axis, responsible for promoting fertility through the cyclic secretion of gonadotropins and steroid hormones, was affected. RT-qPCR and Western blot results demonstrated that the expression of GnRH in the hypothalamus was decreased, the GnRHR in the pituitary gland was decreased, and the expression of FSHβ and LHβ in the pituitary gland was increased. Overall, BPS exposure disrupts the HPO axis, hormone levels, and steroid biosynthesis in the ovaries, affecting offspring development and fertility. This study provides new insights into the potential effects of BPS exposure on the reproductive function of the body and its relevant mechanisms of action.

Medicine (Baltimore) 2023; 102:e36148. [PMID: 38115314 PMCID: PMC10727640 DOI: 10.1097/md.0000000000036148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 10/10/2023] [Accepted: 10/25/2023] [Indexed: 12/21/2023] Open
Abstract
To explore the mechanism of necrotic effect of nourishing cells in the context of genital tract infection in premature rupture of membranes (PROM). One hundred eight patients with PROM treated at our hospital from June 2020 to June 2022 were selected as the PROM group. Simultaneously, 108 cases of normal full-term pregnant women were chosen as the control group. Western blot analysis was performed to measure the relative expression levels of cysteinyl aspartate specific proteinase-1 (Caspase-1), cysteinyl aspartate specific proteinase-3 (Caspase-3), nucleotide-binding oligomerization domain-like receptor family pyrin domain containing 3 (NLRP3), and interleukin (IL)-1β proteins, which are associated with necrosis of placental nourishing cells, in the placenta of both groups. TUNEL staining was used to detect the number of apoptotic placental nourishing cells. The differences in necrotic factors of placental nourishing cells were analyzed between full-term and preterm cases in the PROM group, as well as among patients with different genital tract infections. The apoptotic count of placental nourishing cells in the PROM group was 58.46 ± 11.26 cells/field, which was markedly higher than that of the control group (P < .05). The relative expression levels of the necrotic factors Caspase-1, Caspase-3, NLRP3, and IL-1β proteins in placental nourishing cells of the PROM group were 1.32 ± 0.26, 1.19 ± 0.30, 1.29 ± 0.28, and 1.23 ± 0.24, respectively. These values were significantly higher than those of the control group (P < .05). The relative expression levels of the necrotic factors Caspase-1, Caspase-3, NLRP3, and IL-1β proteins in placental nourishing cells were compared between full-term and preterm patients in the PROM group (P > .05). The relative expression levels of the necrotic factors Caspase-1, Caspase-3, NLRP3, and IL-1β proteins in placental nourishing cells were higher in patients with multiple genital tract infections compared to those with single infections or no infections in the PROM group (P < .05). PROM is associated with a significant upregulation of placental nourishing cell apoptosis and necrotic factors, including Caspase-1, Caspase-3, NLRP3, and IL-1β proteins. This upregulation is correlated with the presence of genital tract infections.
