Toxicology 2022; 477:153279. [PMID: 35926758 DOI: 10.1016/j.tox.2022.153279] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Revised: 07/20/2022] [Accepted: 07/30/2022] [Indexed: 11/17/2022]
Abstract
Di-n-butyl phthalate (DBP) is ubiquitous in environment and has been detected in almost all human bodies. Few data could be found about the effects of DBP on cardiovascular system, though its reproductive toxicities have been studied extensively. This study aimed to explore effects of DBP on phenotypic switching of vascular smooth muscle cells (VSMCs), an essential step during the formation of atherosclerosis (AS). A7r5 cells were employed and exposed to various levels of DBP (10-9, 10-8, 10-7, 10-6, and 10-5 M) or DMSO as control. CCK-8 assay was used to detect the effects of DBP on cell viability. Expressions of mRNA/miRNAs and proteins were measured by qRT-PCR and western blotting, respectively. Bioinformatic analysis and dual-luciferase reporter assay were used to analyze the combination between miR-139-5p and Myocardin (MYOCD). Results revealed that DBP at 10-7 M prompted phenotypic switching from contractile to synthetic of VSMCs by inhibiting contractile VSMCs marker genes via suppressing the expression of MYOCD. Moreover, miR-139c-5p directly targeted MYOCD 3'UTR and modulated MYOCD expression. Besides, DBP inhibited the expression of MYOCD and VSMCs marker genes by upregulating miR-139-5p. Collectively, these data suggested that DBP could promote the phenotypic switching from contractile to synthetic of VSMCs in A7r5 cells through miR-139-5p-MYOCD.

[PMID: 35622664 PMCID: PMC9143992 DOI: 10.3390/toxics10050251] [Citation(s) in RCA: 25] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 05/09/2022] [Accepted: 05/12/2022] [Indexed: 02/04/2023]
Abstract
The female reproductive system is dependent upon the health of the ovaries. The ovaries are responsible for regulating reproduction and endocrine function. Throughout a female’s reproductive lifespan, the ovaries undergo continual structural changes that are crucial for the maturation of ovarian follicles and the production of sex steroid hormones. Phthalates are known to target the ovaries at critical time points and to disrupt normal reproductive function. The US population is constantly exposed to measurable levels of phthalates. Phthalates can also pass placental barriers and affect the developing offspring. Phthalates are frequently prevalent as mixtures; however, most previous studies have focused on the effects of single phthalates on the ovary and female reproduction. Thus, the effects of exposure to phthalate mixtures on ovarian function and the female reproductive system remain unclear. Following a brief introduction to the ovary and its major roles, this review covers what is currently known about the effects of phthalate mixtures on the ovary, focusing primarily on their effects on folliculogenesis and steroidogenesis. Furthermore, this review focuses on the effects of phthalate mixtures on female reproductive outcomes. Finally, this review emphasizes the need for future research on the effects of environmentally relevant phthalate mixtures on the ovary and female reproduction.

Biol Reprod 2021; 102:1290-1305. [PMID: 32149334 PMCID: PMC7703729 DOI: 10.1093/biolre/ioaa027] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Revised: 12/16/2019] [Accepted: 02/27/2020] [Indexed: 02/01/2023] Open
Abstract
Vaspin, visceral-adipose-tissue-derived serine protease inhibitor, is involved in the development of obesity, insulin resistance, inflammation, and energy metabolism. Our previous study showed vaspin expression and its regulation in the ovary; however, the role of this adipokine in ovarian cells has never been studied. Here, we studied the in vitro effect of vaspin on various kinase-signaling pathways: mitogen-activated kinase (MAP3/1), serine/threonine kinase (AKT), signal transducer and activator of transcription 3 (STAT3) protein kinase AMP (PRKAA1), protein kinase A (PKA), and on expression of nuclear factor kappa B (NFKB2) as well as on steroid synthesis by porcine ovarian cells. By using western blot, we found that vaspin (1 ng/ml), in a time-dependent manner, increased phosphorylation of MAP3/1, AKT, STAT3, PRKAA1, and PKA, while it decreased the expression of NFKB2. We observed that vaspin, in a dose-dependent manner, increased the basal steroid hormone secretion (progesterone and estradiol), mRNA and protein expression of steroid enzymes using real-time PCR and western blot, respectively, and the mRNA of gonadotropins (FSHR, LHCGR) and steroids (PGR, ESR2) receptors. The stimulatory effect of vaspin on basal steroidogenesis was reversed when ovarian cells were cultured in the presence of a PKA pharmacological inhibitor (KT5720) and when GRP78 receptor was knocked down (siRNA). However, in the presence of insulin-like growth factor type 1 and gonadotropins, vaspin reduced steroidogenesis. Thus, vaspin, by activation of various signaling pathways and stimulation of basal steroid production via GRP78 receptor and PKA, could be a new regulator of porcine ovarian function.

Abstract
BACKGROUND Endometriosis is a common gynecological condition in which stromal or glandular epithelium is implanted in extrauterine locations. Endometriosis causes detrimental effects on the granulosa cells, and phthalate interferes with the biological and reproductive function of endometrial cells at a molecular level. METHODS This article retrospectively reviewed the studies on phthalate exposure and its relationship with endometriosis. A literature search was performed for scientific articles using the keywords "phthalate and endometriosis," "endometriosis and granulosa cells," "phthalate and granulosa cells," and "phthalates and endometrial cells." RESULTS Endometriosis can affect cytokine production, steroidogenesis, cell cycle progression, expression of estrogen receptor-α (ER-α)/progesterone receptor (PR), and cause endoplasmic reticulum stress, senescence, apoptosis, autophagy, and oxidative stress in the granulosa cells. Mono-n-butyl phthalate (MnBP) alters the expression of cytokines, cell cycle-associated genes, ovarian stimulation, steroidogenesis, and progesterone production. Several in vitro studies have demonstrated that phthalate caused inflammation, invasion, change in cytokines, increased oxidative stress, viability, resistance to hydrogen peroxide, and proliferation of endometrial cells. CONCLUSION This might provide new insights about the impact of phthalate on the pathogenesis of endometriosis and its consequences on the ovarian function.

Ectopic expression of microRNA-874 represses epithelial mesenchymal transition through the NF-κB pathway via CCNE1 in cholangiocarcinoma. Cell Signal 2021; 82:109927. [PMID: 33476715 DOI: 10.1016/j.cellsig.2021.109927] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Revised: 01/13/2021] [Accepted: 01/13/2021] [Indexed: 12/15/2022]
Abstract
Cholangiocarcinoma (CC) is a devastating disease associated with poor survival rate. microRNAs (miRNAs) have recently been reported to assume a great role in CC development. This research aims to explore the functions of miR-874 in regulating epithelial mesenchymal transition (EMT) in CC. In obtained CC tissues and cells, miR-784 expression was assessed by RT-qPCR, and CCNE1 expression by RT-qPCR or immunohistochemistry. Dual-luciferase reporter assay was implemented for relationship between miR-784 and CCNE1. The roles of miR-784, CCNE1 and the NF-κB pathway in CC were investigated on human CC cell lines. CCNE1 was found to be highly expressed in CC while miR-874 expression was lowered in CC tissues and cells, thereby suggesting a negative regulatory effect of CCNE1. In QBC939 and RBE cells, overexpressing miR-874 or silencing CCNE1 led to augmented IκBα and E-cadherin expression, but diminished CCNE1, NF-κB, N-cadherin, and Vimentin expression. Moreover, overexpression of miR-874 or CCNE1 silencing led to reduced cell proliferation, invasion, and migration capabilities. In conclusion, we demonstrated that miR-874 negatively regulated CCNE1 to inhibit the NF-κB pathway, thus consequently suppressing EMT in CC. Therefore, the overexpression of miR-874 might bring favorable outcomes for the treatment of CC.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2020; 264:114723.

Di-n-butyl phthalate (DBP) is ubiquitously in the environment and has been detected in almost all of human bodies. Few data could be found about the effects of DBP on cardiovascular system, though its reproductive toxicities have been studied extensively. This study aimed to explore the effects of DBP on lipid metabolism, a key step during the formation of atherosclerosis, since DBP was recently reported to be associated with atherosclerosis. THP-1 macrophages were employed and exposed to various levels of DBP (10-8, 10-7, 10-6, 10-5 and 10-4 mol/L) or DMSO as control. Lipid accumulation was determined by detection of cellular total cholesterol, free cholesterol, cholesterol ester and content of lipid drops. Expressions of mRNA/miRNAs and proteins were measured by qRT-PCR and western blotting, respectively. Bioinformatic analysis and dual luciferase reporter assay were used to analyze the combination between miR200c-5p and ATP-binding cassette transporter A1 (ABCA1). Cholesterol efflux assay was executed to study the inhibitory effects of DBP on cholesterol efflux capability. Results revealed that DBP at 10-7 mol/L prompted THP-1 macrophages lipid accumulation by inhibiting cholesterol efflux via suppressing ABCA1 expression. In addition, a non-linear inverted U-shaped relationship between DBP and lipid accumulation could be observed. Moreover, miR200c-5p could directly targets to ABCA1 3'UTR and modulate ABCA1 expression. Besides, downregulation of ABCA1 expression and reduction of lipid efflux induced by DBP were due to the miR200c-5p upregulation. Collectively, these data suggested that DBP at levels relative to human exposure could increase lipid accumulation in THP-1 macrophages by decreasing cholesterol efflux through miR200c-5p-ABCA1, then potentiate the formation of atherosclerosis.

Zhang C, Gong P, Ye Y, Zhang L, Chen M, Hu Y, Gu A, Chen S, Wang Y. NF-κB-vimentin is involved in steroidogenesis stimulated by di- n-butyl phthalate in prepubertal female rats. Toxicol Res (Camb) 2018; 7:826-833. [PMID: 30310660 PMCID: PMC6116176 DOI: 10.1039/c8tx00035b] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2018] [Accepted: 04/17/2018] [Indexed: 11/21/2022] Open
Abstract
This study was aimed at assessing steroidogenesis stimulated by low-dose exposure to DBP in prepubertal female rats. Animals were gavaged with DBP from postnatal day 21 to 33 at 0, 1, 10 and 500 mg kg-1 day-1. 500 mg kg-1 day-1 was selected since it was used in numerous studies and the inhibitory effect could be observed at this dosage. After treatment, hormone levels in serum were detected by enzyme-linked immunosorbent assay. mRNA and protein expressions of vimentin, nuclear factor-κB (NF-κB) p65 and phosphorylation of NF-κB p65 (p-p65) were assayed by quantitative real-time polymerase chain reaction (qRT-PCR) assay, western blotting, and immunohistochemistry, respectively. Uterus weights, progesterone levels in serum, and protein expression of vimentin and p-p65 in ovaries increased significantly after the animals were exposed to DBP at 1 mg kg-1 day-1. Additionally, steroidogenesis and vimentin expression stimulated by DBP were blocked when the activity of NF-κB p65 was inhibited by the NF-κB inhibitor, pyrrolidine dithiocarbamic acid (PDTC). These results strongly suggested that DBP may activate uterus development by up-regulated steroidogenesis through the NF-κB-vimentin signaling pathway.
