Adolescent cetylpyridinium chloride exposure impairs homologous recombination repair and induces granulosa cell apoptosis and follicular atresia via FOXM1/CREBBP complex suppression. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2025; 296:118193. [PMID: 40239548 DOI: 10.1016/j.ecoenv.2025.118193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2025] [Revised: 03/14/2025] [Accepted: 04/11/2025] [Indexed: 04/18/2025]
Abstract
Cetylpyridinium chloride (CPC), a widely used surfactant, functions as an antimicrobial agent in pharmaceuticals and personal care products (PPCPs). However, its effect on the female reproductive system remains largely unknown. Herein, female mice were gavaged with 0.01, 0.1, or 1 mg CPC/kg body weight (bw)/d during adolescence. Results showed reduced body and ovarian weights, decreased primordial follicle numbers, and increased atretic follicles. Additionally, CPC disrupted serum hormone levels, reduced cell viability and proliferation, and increased apoptosis in granulosa cells. Transcriptomic analysis of primary granulosa cells revealed altered genes in homologous recombination (HR) repair pathway, including the downregulation of FOXM1 and the MRN complex. Further validation demonstrated decreased expression of HR repair components and increased DNA damage in both in vivo and in vitro. Mechanistically, CPC inhibited the FOXM1/CREBBP interaction and inhibited HR repair gene transcription, including MRE11 and NBS1. Finally, FOXM1 overexpression partially reversed the detrimental effects of CPC on HR repair and cell proliferation. These results indicate that CPC-induced ovarian dysfunction during adolescence is mediated through FOXM1/CREBBP complex inhibition and homologous recombination repair impairment, potentially increasing the risk for the development of diminished ovarian reserve (DOR) and providing new experimental evidence to assess the reproductive toxicity effects of CPC.

Yuan H, Zhou L, Hu W, Yang M. LINC00626 drives tamoxifen resistance in breast cancer cells by interaction with UPF1. Sci Rep 2025; 15:2997. [PMID: 39848992 PMCID: PMC11757752 DOI: 10.1038/s41598-025-86287-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2024] [Accepted: 01/09/2025] [Indexed: 01/25/2025] Open
Abstract
Although tamoxifen is commonly utilized as adjuvant therapy for Estrogen Receptor alpha (ERα)-positive breast cancer patients, approximately 30-50% of individuals treated with tamoxifen experience relapse. Therefore, it is essential to investigate additional factors besides ERα that influence the estrogen response. In this study, cross-analysis of databases were performed, and the results revealed a significant association between LINC00626 and ERα signaling as well as increased expression levels of this gene in tamoxifen-resistant cells. LINC00626 is a novel ERα-regulated long non-coding RNA (lncRNA) that has not yet been examined for its potential contribution to endocrine therapy resistance. This study revealed that the upregulation of LINC00626 in breast cancer was associated with poor overall survival in patients. Additionally, ERα signaling was found to transcriptionally regulate LINC00626 expression, thereby promoting cancer progression and enhancing resistance to tamoxifen in breast cancer cells via the regulation of UPF1 expression. Depletion of LINC00626 restored sensitivity to tamoxifen by activating the PERK-ATF4-CHOP signaling pathway via UPF1. These findings support the role of LINC00626 as a potential therapeutic target for combating tamoxifen resistance.

Zhao Q, Pan J, Bao Y, Wang X, Shi W. Prenatal exposure to bisphenol A causes reproductive damage in F1 male rabbits due to inflammation and oxidative stress. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2025; 290:117735. [PMID: 39862691 DOI: 10.1016/j.ecoenv.2025.117735] [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: 10/19/2024] [Revised: 12/26/2024] [Accepted: 01/12/2025] [Indexed: 01/27/2025]
Abstract
Bisphenol A (BPA) is used extensively in producing industrial chemicals such as plastic products, resin, and paper coatings. Concerns have been expressed regarding its possible detrimental consequences, especially on the reproductive system of mammals. Despite extensive study in this domain, there has been no targeted examination of the impact of BPA on F1 generation rabbits. BPA exposure model was developed in pregnant female rabbits to examine the effects of BPA on reproductive hormones, cellular apoptosis, oxidative stress, inflammatory response, and tissue integrity in weaning rabbits. The results indicated that BPA exposure triggered an inflammatory response and oxidative stress, consequently impacting the reproductive system of weaned rabbits and altering reproductive hormone levels. By modulation of the Nrf2 and NF-κB axes, BPA could influence the expression of antioxidant enzymes and inflammatory mediators in the rabbit reproductive system, leading to cell apoptosis and tissue damage. These results underscore the importance of monitoring BPA exposure during pregnancy and emphasize the necessity of implementing measures to mitigate its potential effects on the reproductive health of offspring.

Abstract
Reproductive disorders are considered a global health problem influenced by physiological, genetic, environmental, and lifestyle factors. The increased exposure to bisphenols, a chemical used in large quantities for the production of polycarbonate plastics, has raised concerns regarding health risks in humans, particularly their endocrine-disrupting effects on female reproductive health. To provide a basis for future research on environmental interference and reproductive health, we reviewed relevant studies on the exposure patterns and levels of bisphenols in environmental matrices and humans (including susceptible populations such as pregnant women and children). In addition, we focused on in vivo, in vitro, and epidemiological studies evaluating the effects of bisphenols on the female reproductive system (the uterus, ovaries, fallopian tubes, and vagina). The results indicate that bisphenols cause structural and functional damage to the female reproductive system by interfering with hormones; activating receptors; inducing oxidative stress, DNA damage, and carcinogenesis; and triggering epigenetic changes, with the damaging effects being intergenerational. Epidemiological studies support the association between bisphenols and diseases such as cancer of the female reproductive system, reproductive dysfunction, and miscarriage, which may negatively affect the establishment and maintenance of pregnancy. Altogether, this review provides a reference for assessing the adverse effects of bisphenols on female reproductive health.
