Mol Cell Endocrinol 2024; 580:112111.

Abstract
Before menopause, females exhibit a lower incidence of cardiovascular disease than age-matched males, possibly owing to the protective effects of sex hormones. 17β-estradiol (17β-E2) protects against oxidative stress-induced injury by suppressing thrombospondin-1 (THBS1) expression in endothelial cells. Here, we examined the role of 17β-E2-mediated THBS1 suppression in preventing cell senescence and apoptosis. Human umbilical vein endothelial cells (HUVECs) were cultivated and treated with siRNA or overexpression plasmids to regulate THBS1. H2O2, estrogen-activity modulating drugs, and LY2109761 (a TGF-β kinase inhibitor) treatments were applied. THBS1 knockdown repressed, and its overexpression aggravated, H2O2-induced cell injury, affecting cell death, proliferation, senescence, and apoptosis. 17β-E2 inhibited THBS1 mRNA and protein expression time- and dose-dependently, by targeting ERβ. THBS1 overexpression blocked 17β-E2 from preventing H2O2-induced injury, significantly activating the TGF-β/Smad pathway. 17β-E2 inhibited H2O2-induced oxidative stress by downregulating THBS1 expression and TGF-β/Smad signaling in HUVECs. The THBS1/TGF-β/Smad axis could thus be a therapeutic target.

Abstract
OBJECTIVES This study aimed to analyze the role of estrogen in noise-induced hearing loss (NIHL) and uncover underlying mechanisms. METHODS An ovariectomized Sprague-Dawley rat model (OVX) was constructed to investigate the hearing threshold and auditory latency before and after noise exposure using the auditory brainstem response (ABR) test. The morphological changes were assessed using immunofluorescence, scanning electron microscopy and transmission electron microscopy. Proteomics and bioinformatics were used to analyze the mechanism. The findings were further verified through western blot and Luminex liquid suspension chip technology. RESULTS After noise exposure, OVX rats exhibited substantially elevated hearing thresholds. A conspicuous delay in ABR wave I latency was observed, alongside increased loss of outer hair cells, severe collapse of stereocilia and pronounced deformation of the epidermal plate. Accordingly, OVX rats with estrogen supplementation exhibited tolerance to NIHL. Additionally, a remarkable upregulation of the thrombospondin 1 (Tsp1)-CD47 axis in OVX rats was discovered and verified. CONCLUSIONS OVX rats were more susceptible to NIHL, and the protective effect of estrogen was achieved through regulation of the Tsp1-CD47 axis. This study presents a novel mechanism through which estrogen regulates NIHL and offers a potential intervention strategy for the clinical treatment of NIHL.

Abstract
Keloids are defined histopathologically as an inflammatory disorder characterized by exhibiting numerous fibroblasts, abnormal vascularization, increased number of proinflammatory immune cells as well as uncontrolled cell proliferation, and exacerbated and disorganized deposition of extracellular matrix (ECM) molecules. Importantly, many of these ECM molecules display N- and O-linked glycan residues and are considered as potential targets for galectin-1 (Gal-1) and galectin-3 (Gal-3). Nevertheless, the presence and localization of Gal-1 and Gal-3 as well as the interactions with some of their binding partners in keloid tissues have not been considered. Here, we show that in the dermal thickening of keloids, versican, syndecan-1, fibronectin, thrombospondin-1, tenascin C, CD44, integrin β1, and N-cadherin were immunolocalized in the elongated fibroblasts that were close to the immune cell infiltrate, attached to collagen bundles, and around the microvasculature and in some immune cells. We also show that Gal-1 and Gal-3 were present in the cytoplasm and along the cell membrane of some fibroblasts and immune and endothelial cells of the dermal thickening. We suggest that Gal-1 and Gal-3, in concert with some of the ECM molecules produced by fibroblasts and by immune cells, counteract the inflammatory response in keloids. We also proposed that Gal-1 and Gal-3 through their binding partners may form a supramolecular structure at the cell surface of fibroblasts, immune cells, endothelial cells, and in the extracellular space that might influence the fibroblast morphology, adhesion, proliferation, migration, and survival as well as the inflammatory responses.

Abstract
KEY POINTS The catechol metabolites of 17β-oestradiol (E2 β), 2-hydroxyoestradiol (2-OHE2 ) and 4-hydroxyoestradiol (4-OHE2 ), stimulate proliferation of pregnancy-derived ovine uterine artery endothelial cells (P-UAECs) through β-adrenoceptors (β-ARs) and independently of the classic oestrogen receptors (ERs). Herein we show that activation of ERK1/2, p38 and JNK mitogen activated protein kinases (MAPKs) is necessary for 2-OHE2 - and 4-OHE2 -induced P-UAEC proliferation, as well as proliferation induced by the parent hormone E2 β and other β-AR signalling hormones (i.e. catecholamines). Conversely, although 2-OHE2 and 4-OHE2 rapidly activate phosphatidylinositol 3-kinase (PI3K), its activation is not involved in catecholoestradiol-induced P-UAEC proliferation. We also show for the first time the signalling mechanisms involved in catecholoestradiol-induced P-UAEC proliferation; which converge at the level of MAPKs with the signalling mechanisms mediating E2 β- and catecholamine-induced proliferation. The present study advances our understanding of the complex signalling mechanisms involved in regulating uterine endothelial cell proliferation during pregnancy. ABSTRACT Previously we demonstrated that the biologically active metabolites of 17β-oestradiol, 2-hydroxyoestradiol (2-OHE2 ) and 4-hydroxyoestradiol (4-OHE2 ), stimulate pregnancy-specific proliferation of uterine artery endothelial cells derived from pregnant (P-UAECs), but not non-pregnant ewes. However, unlike 17β-oestradiol, which induces proliferation via oestrogen receptor-β (ER-β), the catecholoestradiols mediate P-UAEC proliferation via β-adrenoceptors (β-AR) and independently of classic oestrogen receptors. Herein, we aim to further elucidate the signalling mechanisms involved in proliferation induced by catecholoestradiols in P-UAECs. P-UAECs were treated with 2-OHE2 and 4-OHE2 for 0, 0.25, 0.5, 1, 2, 4, 12 and 24 h, to analyse activation of mitogen activated protein kinases (MAPKs) and phosphatidylinositol 3-kinase (PI3K)-AKT. Specific inhibitors for ERK1/2 MAPK (PD98059), p38 MAPK (SB203580), JNK MAPK (SP600125), or PI3K (LY294002) were used to determine the involvement of individual kinases in agonist-induced P-UAEC proliferation. 2-OHE2 and 4-OHE2 stimulated biphasic phosphorylation of ERK1/2, slow p38 and JNK phosphorylation over time, and rapid monophasic AKT phosphorylation. Furthermore, ERK1/2, p38 and JNK MAPKs, but not PI3K, were individually necessary for catecholoestradiol-induced proliferation. In addition, when comparing the signalling mechanisms of the catecholoestradiols, to 17β-oestradiol and catecholamines, we observed that convergent MAPKs signalling pathways facilitate P-UAEC proliferation induced by all of these hormones. Thus, all three members of the MAPK family mediate the mitogenic effects of catecholoestradiols in the endothelium during pregnancy. Furthermore, the convergent signalling of MAPKs involved in catecholoestradiol-, 17β-oestradiol- and catecholamine-induced endothelial cell proliferation may be indicative of unappreciated evolutionary functional redundancy to facilitate angiogenesis and ensure maintenance of uterine blood flow during pregnancy.

Abstract
CCN5/WISP-2 is an anti-invasive molecule and prevents breast cancer (BC)
progression. However, it is not well understood how CCN5 prevents invasive phenotypes
of BC cells. CCN5 protein expression is detected in estrogen receptor-α
(ER-α) -positive normal breast epithelial cells as well as BC cells, which are
weakly invasive and rarely metastasize depending on the functional status of
ER-α. A unique molecular relation between CCN5 and ER-α has been
established as the components of the same signaling pathway that coordinate some
essential signals associated with the proliferation as well as delaying the disease
progression from a non-invasive to invasive phenotypes. Given the importance of this
connection, we determined the role of CCN5 in regulation of ER-α in different
cellular settings and their functional relationship. In a genetically engineered
mouse model, induced expression of CCN5 in the mammary ductal epithelial cells by
doxycycline promotes ER-α expression. Similarly, CCN5 regulates ER-α
expression and activity in normal and neoplastic breast cells, as documented in
various in vitro settings such as mouse mammary gland culture, human mammary
epithelial cell and different BC cell cultures in the presence or absence of human
recombinant CCN5 (hrCCN5) protein. Mechanistically, at least in the BC cells, CCN5 is
sufficient to induce ER-α expression at the transcription level via interacting
with integrins-α6β1 and suppressing Akt followed by activation of FOXO3a.
Moreover, in vitro and in vivo functional assays indicate that CCN5
treatment promotes response to tamoxifen in triple-negative BC (TNBC) cells possibly
via restoring ER-α. Collectively, these studies implicates that the combination
treatments of CCN5 (via activation of CCN5 or hrCCN5 treatment) and tamoxifen as
potential therapies for TNBC.

Abstract
BACKGROUND Angiogenesis is an essential process in endometriosis disease progression. Earlier, we demonstrated that anti-angiogenic peptide, ABT-898 prevents neoangiogenesis of human endometriotic lesions in a xenograft mouse model. Since angiogenesis is essential for normal ovarian and uterine function, we evaluated effects of ABT-898 on normal female reproductive processes in mice. METHODS Cycling female C57BL/6N mice were dosed with ABT-898 (100 mg/kg) or 5 % dextrose control for 21 consecutive days to cover multiple estrous cycles (average estrous cycle 4 to 5 days in mice). Pregnant female mice were dosed with ABT-898 (100 mg/kg) or control on alternate days over the course of gestation, beginning at gestation day 7.5 to 17.5 (gestation length 21 days). Histological analysis along with CD31 and Vimentin immunohistochemistry were performed on ovaries and uteri obtained from treated and control mice. To understand the influence of ABT-898 on systemic angiogenic factors, a Pro Mouse Cytokine 9-plex assay was performed on plasma samples obtained from mice prior to treatment, during the second week of ABAT-898 or control treatment and on the last day of treatment. RESULTS ABT-898 did not affect the number of estrous cycles over the 21 day treatment compared to control. Histological analysis of ovaries found no difference in the number of primordial, primary, secondary, and antral follicles between ABT-898 treated and control groups. Similarly, no difference was observed in the microvessel density between ABT-898 treated and control uteri, ovarian follicles or corpus luteum when assessed using CD31 or vimentin immunohistochemistry. Electron microscopy revealed similar capillary structure and appearance in both ABT-898 treated and control uteri. Although peripheral blood angiogenic cytokine profiles (IL-15, IL-18, M-CSF, b-FGF, PDGF-bb, MIG, MIP-2, LIF and VEGF) changed over the course of the intervention, there was no significant difference between ABT-898 and control groups at any of the studied time points. Treatment with ABT-898 during pregnancy had no effect on litter size at birth, pup weight at birth or pup weight at weaning. CONCLUSION Our findings suggest that ABT-898 may not alter angiogenesis dependent reproductive processes in female mice. However, an extensive reproductive toxicology screening is required to substantiate use of ABT-898 in future.

Abstract
Angiogenesis plays important roles in tumor growth and metastasis, thus development of a novel angiogenesis inhibitor is essential for the improvement of therapeutics against cancer. Thrombospondins-1 (TSP-1) is a potent endogenous inhibitor of angiogenesis that acts through direct effects on endothelial cell migration, proliferation, survival, and activating apoptotic pathways. TSP-1 has been shown to disrupt estrogen-induced endothelial cell proliferation and migration. Here we investigated the potential of pterostilbene carboxaldehyde thiosemicarbazone (PTERC-T), a novel resveratrol (RESV) derivative, to inhibit angiogenesis induced by female sex steroids, particularly 17β-Estradiol (E2), on Human umbilical vein endothelial cells (HUVECs) and to elucidate the involvement of TSP-1 in PTERC-T action. Our results showed that PTERC-T significantly inhibited 17β-E2-stimulated proliferation of HUVECs and induced apoptosis as determined by annexin V/propidium iodide staining and cleaved caspase-3 expression. Furthermore, PTERC-T also inhibited endothelial cell migration, and invasion in chick chorioallantoic membrane (CAM) assay. In contrast, RESV failed to inhibit 17β-E2 induced HUVECs proliferation and invasion at similar dose. PTERC-T was also found to increase TSP-1 protein expression levels in a dose-dependent manner which, however, was counteracted by co-incubation with p38MAPK or JNK inhibitors, suggesting involvement of these pathways in PTERC-T action. These results suggest that the inhibitory effect of PTERC-T on 17β-E2 induced angiogenesis is associated, at least in part, with its induction of endothelial cell apoptosis and inhibition of cell migration through targeting TSP-1. Thus, PTERC-T could be considered as a potential lead compound for developing a class of new drugs targeting angiogenesis-related diseases.

Abstract
Reduced ovarian hormone levels associated with menopause or ovariectomy (OVX) not only result in vascular dysfunction but also lead to structural abnormalities in capillaries. Therefore, the effect of OVX on the three-dimensional (3-D) architecture of capillary networks and the underlying molecular mechanisms were investigated in rat soleus muscle. Seven-week-old female Wistar rats were divided into the OVX and sham-treated (Sham) groups. The OVX group exhibited lower endurance exercise capacity compared to the sham group and resulted in decreased capillary diameter, number of anastomoses and capillary/anastomosis volume in soleus muscle, indicating 3-D structural abnormalities of capillary networks. Furthermore, OVX led to increased concentrations of thrombospondin-1 (TSP-1) protein and a decreased VEGF-A/TSP-1 ratio, an indicator of angio-adaptations, in soleus muscle compared with the Sham group. These results indicate OVX may induce 3-D capillary regression in soleus muscle through an imbalance between VEGF-A and TSP-1 expression, possibly associated with decreased exercise tolerance in ovariectomized rats.

Abstract
PURPOSE The effects of reproductive hormones on ovarian cancer growth are not well understood. Here, we examined the effects of estrous cycle variation and specific reproductive hormones on ovarian cancer growth. EXPERIMENTAL DESIGN We investigated the role of reproductive hormones in ovarian cancer growth using both in vivo and in vitro models of tumor growth. RESULTS In vivo experiments using the HeyA8 and SKOV3ip1 ovarian cancer models showed that tumor cell inoculation during proestrus significantly increased tumor burden (251-273%) compared with injection during the estrus phase. Treatment of ovariectomized mice with 17beta-estradiol resulted in a 404% to 483% increase in tumor growth compared with controls. Progestins had no significant effect, but did block estrogen-stimulated tumor growth. Tumors collected from mice sacrificed during proestrus showed increased levels of vascular endothelial growth factor (VEGF) and microvessel density compared with mice injected during estrus. HeyA8, SKOV3ip1, and mouse endothelial (MOEC) cells expressed estrogen receptor alpha and beta and progesterone receptor at the protein and mRNA levels, whereas 2774 ovarian cancer cells were estrogen receptor-negative. In vitro assays showed that 17beta-estradiol significantly increased ovarian cancer cell adhesion to collagen in estrogen receptor-positive, but not in estrogen receptor-negative cells. Additionally, 17beta-estradiol increased the migratory potential of MOEC cells, which was abrogated by the mitogen-activated protein kinase (MAPK) inhibitor, PD 09859. Treatment with 17beta-estradiol activated MAPK in MOEC cells, but not in HeyA8 or SKOV3ip1 cells. CONCLUSION Our data suggest that estrogen may promote in vivo ovarian cancer growth, both directly and indirectly, by making the tumor microenvironment more conducive for cancer growth.

Abstract
Previously, we have shown that the expression of Wnt-1-induced signaling protein-2 (WISP-2), also known as CCN5, can be regulated by multiple stimulants in estrogen receptor (ER)-positive breast tumor cells to exert their mitogenic action in these cells. Here, we show that insulin-like growth factor-1 (IGF-1), a strong mitogen, enhanced the expression of the WISP-2/CCN5 gene parallel with the induction of proliferation of ER-positive breast tumor cells. An additive effect was also seen in combination with estrogen. Perturbation of IGF-1-induced WISP-2/CCN5 expression by WISP-2-specific RNA interference impaired the mitogenic action of IGF-1 on ER-positive breast tumor cells. Furthermore, the studies have shown that the multiple molecular cross-talks and side-talks among IGF-1R, ER-alpha, and phosphatidylinositol 3-kinase (PI3K)/Akt signaling molecules are required to induce WISP-2/CCN5 mRNA by IGF-1 in ER-positive, noninvasive breast tumor cells. Because a pure anti-ER ICI 182,780 is not only able to suppress the up-regulation of WISP-2/CCN5 mRNA expression by IGF-1, it also suppresses the PI3K/Akt activity induced by IGF-1 in MCF-7 cells; we anticipate that the membrane ER receptor may participate in this event. Collectively, these studies propose for the first time that WISP-2/CCN5 is an integral signaling molecule in mitogenic action of IGF-1 axis in ER-positive human breast tumor cells.

Abstract
Abstract
In order to understand why the angiogenesis inhibitor thrombospondin-1 (TSP1) is often, although not always, associated with prostatic tumors, we have investigated its relationship with the testosterone and the vasculature on which both normal and tumorigenic prostatic epithelia depend. In vivo, androgen withdrawal led to increased TSP1 production and decreased vascularization in the normal rat prostate which was reversed by androgen replacement. Androgen repression of TSP1 production occurred at the transcriptional level and was dependent on the presence of the first intron of the TSP1 gene. In an experimental model of prostate tumorigenesis, TSP1, when delivered by admixed stromal fibroblasts, markedly delayed LNCaP tumor growth and limited tumor vascularization. However, prolonged exposure to TSP1 resulted in the growth of tumors secreting high levels of vascular endothelial growth factor in the bloodstream of tumor-bearing animals and tumor growth was no longer sensitive to TSP1 inhibitory effects. Clinical evidence also suggested that prostate carcinomas are able to adapt to escape the antiangiogenic effects of TSP1. In human androgen–dependent localized prostate carcinomas, TSP1 expression was inversely correlated with blood vessel density. Androgen deprivation in patients with hormone-responsive tumors led to increased TSP1 expression and vascular regression. In contrast, despite a sustained expression in the tumor bed, TSP1 was no longer associated with decreased vascularization in hormone-refractory prostate tumors. Overall, these results suggest that the high in situ TSP1 exposure triggered by androgen deprivation in patients with prostate cancer could lead to early tumor resistance. Such patients could benefit from a combination of androgen deprivation and antiangiogenic therapy in order to minimize the induction of such tumor escape.
