Abstract
Estradiol represents a key steroid ovarian hormone that not only plays a vital role in ovarian follicular development but also is associated with many other reproductive functions. Our primary study revealed that miR-574 expression decreased in porcine granulosa cells during development from small to large follicles, and the increase of ERK1/2 phosphorylation accompanies this change. Since it has been well established that the ERK1/2 activity is tightly associated with granulosa cell functions, including ovarian hormone production, we thus further investigate if the miRNA is involved in the regulation of estradiol production in granulosa cells. We found that overexpression of miR-574 decreased phosphorylated ERK1/2 without affecting the level of ERK1/2 protein, and on the other hand, the inhibition of miR-574 increased phosphorylated ERK1/2 level (P<0.05); meanwhile, overexpression of miR-574 increased estradiol production but knockdown of miR-574 decreased estradiol level in granulosa cells. To further identify the potential mechanism involved in the miR-574 regulatory effect, in silico screening was performed and revealed a potential binding site on the 3'UTR region of the tissue inhibitor of metalloproteinase 3 (TIMP3). Our gain-, loss- of function experiments, and luciferase reporter assay confirmed that TIMP3 is indeed the target of miR-574 in granulosa cell. Furthermore, the siRNA TIMP3 knockdown resulted in decreased phosphorylated ERK1/2, and an increase in estradiol production. In contrast, the addition of recombinant TIMP3 increased phosphorylated ERK1/2 level and decreased estradiol production. In summary, our results suggest that the miR-574-TIMP3-pERK1/2 cascade may be one of the pathways by which microRNAs regulate granulosa cell estradiol production.

Development and validation of a LRP1B mutation-associated prognostic model for hepatocellular carcinoma. Biosci Rep 2021; 41:229519. [PMID: 34386813 PMCID: PMC8415215 DOI: 10.1042/bsr20211053] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 07/28/2021] [Accepted: 07/29/2021] [Indexed: 11/17/2022] Open
Abstract
PURPOSE To develop a LRP1B gene mutation based prognostic model for hepatocellular carcinoma (HCC) patients risk prediction. Methods: The LRP1B gene mutation rate was calculated from HCC patient samples. Meanwhile, differentially expressed genes according to LRP1B mutant were screened out for prognostic model establishment. Based on this innovative model, HCC patients were categoried into high and low-risk group. The immune status including immune cell infiltration ratio and checkpoints have been explored in two groups. The functions of LRP1B and risk factors in the model were verified using both in vivo and in vitro experiments. RESULTS It could be demonstrated that LRP1B was a potential negative predictor for HCC patients prognosis with high mutation frequency. The functions of LRP1B was verified with ELISA assay and Quantitative Real-time PCR method based on clinical recruited HCC participants. 11 genes displayed significant differences according to LRP1B status, which could better predict HCC patient prognosis. The functions of these genes were examined using HCC cell line HCCLM3, suggesting they played a pivotal role in determining HCC cell proliferation and apoptosis. From the immune cell infiltration ratio analysis, there was a significant difference in the infiltration degree of 7 types of immune cells and 2 immune checkpoints between high and low-risk HCC patients. CONCLUSION This study hypothesized a potential prognostic biomarker and developed a novel LRP1B mutation-associated prognostic model for hepatocellular carcinoma, which provided a systematic reference for future understanding of clinical research.

Abstract
Simple Summary Members of the adamalysin family are multi-domain proteins involved in many cancer-related functions. In this review, we will examine the literature on the involvement of adamalysins in hepatocellular carcinoma progression and their importance in the tumor microenvironment where they regulate the inflammatory response and the epithelial–mesenchymal transition. We complete this review with an analysis of adamalysin expression in a large cohort of patients with hepatocellular carcinoma from The Cancer Genome Atlas (TCGA) database. These original results give a new insight into the involvement of all adamalysins in the primary liver cancer. Abstract The tumor microenvironment plays a major role in tumor growth, invasion and resistance to chemotherapy, however understanding how all actors from microenvironment interact together remains a complex issue. The tumor microenvironment is classically represented as three closely connected components including the stromal cells such as immune cells, fibroblasts, adipocytes and endothelial cells, the extracellular matrix (ECM) and the cytokine/growth factors. Within this space, proteins of the adamalysin family (ADAM for a disintegrin and metalloproteinase; ADAMTS for ADAM with thrombospondin motifs; ADAMTSL for ADAMTS-like) play critical roles by modulating cell–cell and cell–ECM communication. During last decade, the implication of adamalysins in the development of hepatocellular carcinoma (HCC) has been supported by numerous studies however the functional characterization of most of them remain unsettled. In the present review we propose both an overview of the literature and a meta-analysis of adamalysins expression in HCC using data generated by The Cancer Genome Atlas (TCGA) Research Network.

Single-nucleotide polymorphisms in the coding region of a disintegrin and metalloproteinase with thrombospondin motifs 4 and hepatocellular carcinoma: A retrospective case-control study. Cancer Med 2019; 8:7869-7880. [PMID: 31663692 PMCID: PMC6912020 DOI: 10.1002/cam4.2646] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2019] [Revised: 09/22/2019] [Accepted: 10/10/2019] [Indexed: 02/06/2023] Open
Abstract
Previous studies have shown that single-nucleotide polymorphisms (SNPs) of a disintegrin and metalloproteinase with thrombospondin type 1 motif 4 (ADAMTS4) may involve in the pathogenesis of some diseases. However, it is not clear whether they are associated with hepatocellular carcinoma (HCC). A hospital-based case-control study, including 862 cases with HCC and 1120 controls, was conducted to assess the effects of 258 SNPs in the coding regions of ADAMTS4 on HCC risk and prognosis. We found that six SNPs in ADAMTS4 were differential distribution between cases and controls via the primary screening analyses; however, only rs538321148 and rs1014509103 polymorphisms were further identified to modify the risk of HCC (odds ratio: 2.73 and 2.95; 95% confidence interval, 2.28-3.29 and 2.43-3.58; P-value, 5.73 × 10-27 and 1.36 × 10-27 , respectively). Significant interaction between these two SNPs and two known causes of hepatitis B virus and aflatoxin B1 were also observed. Furthermore, rs538321148 and rs1014509103 polymorphisms were associated not only with clinicopathological features of tumor such as tumor stage and grade, microvessel density, and vessel metastasis, but with poor overall survival. Additionally, these SNPs significantly downregulated ADATMS4 expression in tumor tissues. These data suggest that SNPs in the coding region of ADAMTS4, such as rs538321148 and rs1014509103, may be potential biomarkers for predicting HCC risk and prognosis.

MicroRNA-21 up-regulates metalloprotease by down-regulating TIMP3 during cumulus cell-oocyte complex in vitro maturation. Mol Cell Endocrinol 2018; 477:29-38.

Abstract
Cumulus cells and the remodeling of their extracellular matrix around oocytes are essential for oocyte maturation and ovulation in the ovary. An important extracellular metalloprotease, ADAMTS1, and its partner VERSICAN, mediate essential cumulus-oocyte-complex (COC) structural remodeling. However, how the expression of these proteinases is regulated during oocyte maturation is unclear. Here we report that both ADAMTS1 and VERSICAN significantly increased in porcine cumulus cells during COC in vitro maturation (IVM). Interestingly, one of the tissue inhibitors of the metalloproteinase family member, TIMP3, was found to be significantly decreased in cumulus cells during this process. Down-regulation of TIMP3 using specific small interfering RNA decreased TIMP3 expression, while increased the levels of ADAMTS1 and VERSICAN, suggesting an inverse relationship between TIMP3, the metalloprotease, and the breakdown product of its substrate. MiR-21 significantly increased in cumulus cells during COC maturation. Knockdown of miR-21 in cumulus cells during COC maturation resulted in increased TIMP3 and decreased ADAMTS1 and VERSICAN expression, which is accompanied by a decrease in cumulus cell expansion and the ratio of oocytes that reached MII stage. In contrast, over-expression of miR-21 decreased TIMP3 and increased ADAMTS1, and enhanced cumulus cell expansion and oocyte maturation. Moreover, in silico prediction revealed that a miR-21 binding site is present at the 3-untranslated region (3-UTR) of the TIMP3 mRNA, which was further confirmed to be the target site of miR-21 by luciferase gene reporter assays. Our findings revealed that miR-21 promotes cumulus expansion and oocyte maturation via down-regulating TIMP3, and subsequent increase of ADAMTS1 and VERSICAN during in vitro COC maturation.

Abstract
Current guidelines recommend low-molecular-weight heparin treatment in patients with cancer with established venous thromboembolism (VTE). The aim of this article was to study the pharmacological properties and effectiveness of tinzaparin in patients with cancer as well as its potential anticancer properties. A search of PubMed and ScienceDirect databases up to March 2016 was carried out to identify published studies that detect the properties and use of tinzaparin in oncology. Protamine sulfate partially (60% to 65%) neutralized tinzaparin’s anti-Xa activity. No dose adjustment of tinzaparin is needed even in patients with severe renal impairment and Creatinine Clearance ≥20 mL/min. Tinzaparin demonstrated a statistically significant decline in VTE recurrence at 1 year post the index thromboembolic event. A statistically significant reduction in minor bleeding rates was also described, whereas major bleeding events did not decrease in patients with cancer treated with tinzaparin versus those who received vitamin K antagonists. Tinzaparin treatment in patients suffering from deep vein thrombosis reduced the incidence of postthrombotic syndrome and venous ulcers. Tinzaparin’s ability to prevent both metastatic dissemination of cancer cells and tumor angiogenesis has been delineated in preclinical research. Current data show that tinzaparin is safe and efficacious either for short-term or for long-term treatment of VTE in patients with cancer. Clinical trials are needed in order to examine the utility of tinzaparin in primary prevention of VTE and validate its potential anticancer advantages exhibited in preclinical research.

Abstract
BACKGROUND & AIMS Increased prevalence of obesity is paralleled by an increase in non-alcoholic steatohepatitis (NASH). We previously found that the expression of ADAMTS5 (A Disintegrin And Metalloproteinase with Thrombospondin type 1 motifs; member 5) is enhanced in expanding adipose tissue. However, no information is available on a potential role in liver pathology. We studied the effect of ADAMTS5 deficiency on NASH in mice. METHODS Wild-type (Adamts5+/+ ) and deficient (Adamts5-/- ) mice were kept on a standard- or high-fat diet (HFD) for 15 weeks. Alternatively, steatohepatitis was induced with methionine/choline-deficient (MCD) diet. RESULTS HFD feeding resulted in comparable body weights for both genotypes, but Adamts5-/- mice had approximately 40% lower liver weight (P = 0.0004). In the Adamts5-/- mice, the HFD as well as the MCD diet consistently induced less NASH with less fibrosis. The deteriorating effect of ADAMTS5 on the liver during diet-induced obesity may be due, at least in part, to proteolytic cleavage of the matrix components syndecan-1 and versican, thereby enhancing hepatic triglyceride clearance from the circulation. Plasma lipid levels were elevated in obese Adamts5-/- mice. There was no clear effect of ADAMTS5 deficiency on glycaemia or glucose tolerance, whereas insulin sensitivity was somewhat improved. Furthermore, Adamts5-/- mice were protected from hepatic mitochondrial dysfunction, as indicated by increased mitochondrial respiratory chain complex activity, higher ATP levels and higher expression of antioxidant enzymes. CONCLUSIONS Absence of ADAMTS5 preserves liver integrity in a diet-induced obesity model. Selective targeting of ADAMTS5 could provide a new therapeutic strategy for treatment/prevention of NASH.

Abstract
Remodelling of the extracellular matrix (ECM) has emerged as a key factor in cancer progression. Proteoglycans, including versican and other hyalectans, represent major structural elements of the ECM where they interact with other important molecules, including the glycosaminoglycan hyaluronan and the CD44 cell surface receptor. The hyalectan proteoglycans are regulated through cleavage by the proteolytic actions of A Disintegrin-like And Metalloproteinase domain with Thrombospondin-1 motif (ADAMTS) family members. Alteration in the balance between hyalectan proteoglycans and ADAMTS enzymes has been proposed to be a crucial factor in cancer progression either in a positive or negative manner depending on the context. Further complexity arises due to the formation of bioactive cleavage products, such as versikine, which may also play a role, and non-enzymatic functions for ADAMTS proteins. This research is providing fresh insights into cancer biology and opportunities for the development of new diagnostic and treatment strategies.

Human Cytomegalovirus Immediate-Early 1 Protein Rewires Upstream STAT3 to Downstream STAT1 Signaling Switching an IL6-Type to an IFNγ-Like Response. PLoS Pathog 2016; 12:e1005748. [PMID: 27387064 PMCID: PMC4936752 DOI: 10.1371/journal.ppat.1005748] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2016] [Accepted: 06/16/2016] [Indexed: 12/24/2022] Open
Abstract
The human cytomegalovirus (hCMV) major immediate-early 1 protein (IE1) is best known for activating transcription to facilitate viral replication. Here we present transcriptome data indicating that IE1 is as significant a repressor as it is an activator of host gene expression. Human cells induced to express IE1 exhibit global repression of IL6- and oncostatin M-responsive STAT3 target genes. This repression is followed by STAT1 phosphorylation and activation of STAT1 target genes normally induced by IFNγ. The observed repression and subsequent activation are both mediated through the same region (amino acids 410 to 445) in the C-terminal domain of IE1, and this region serves as a binding site for STAT3. Depletion of STAT3 phenocopies the STAT1-dependent IFNγ-like response to IE1. In contrast, depletion of the IL6 receptor (IL6ST) or the STAT kinase JAK1 prevents this response. Accordingly, treatment with IL6 leads to prolonged STAT1 instead of STAT3 activation in wild-type IE1 expressing cells, but not in cells expressing a mutant protein (IE1dl410-420) deficient for STAT3 binding. A very similar STAT1-directed response to IL6 is also present in cells infected with a wild-type or revertant hCMV, but not an IE1dl410-420 mutant virus, and this response results in restricted viral replication. We conclude that IE1 is sufficient and necessary to rewire upstream IL6-type to downstream IFNγ-like signaling, two pathways linked to opposing actions, resulting in repressed STAT3- and activated STAT1-responsive genes. These findings relate transcriptional repressor and activator functions of IE1 and suggest unexpected outcomes relevant to viral pathogenesis in response to cytokines or growth factors that signal through the IL6ST-JAK1-STAT3 axis in hCMV-infected cells. Our results also reveal that IE1, a protein considered to be a key activator of the hCMV productive cycle, has an unanticipated role in tempering viral replication. Our previous work has shown that the human cytomegalovirus (hCMV) major immediate-early 1 protein (IE1) modulates host cell signaling pathways involving proteins of the signal transducer and activator of transcription (STAT) family. IE1 has also long been known to facilitate viral replication by activating transcription. In this report we demonstrate that IE1 is as significant a repressor as it is an activator of host gene expression. Many genes repressed by IE1 are normally induced via STAT3 signaling triggered by interleukin 6 (IL6) or related cytokines, whereas many genes activated by IE1 are normally induced via STAT1 signaling triggered by interferon gamma (IFNγ). Our results suggest that the repression of STAT3- and the activation of STAT1-responsive genes by IE1 are coupled. By targeting STAT3, IE1 rewires upstream STAT3 to downstream STAT1 signaling. Consequently, genes normally induced by IL6 are repressed while genes normally induced by IFNγ become responsive to IL6 in the presence of IE1. We also demonstrate that, by switching an IL6 to an IFNγ-like response, IE1 tempers viral replication. These results suggest an unanticipated dual role for IE1 in either promoting or limiting hCMV propagation and demonstrate how a key viral regulatory protein merges two central cellular signaling pathways to divert cytokine responses relevant to hCMV pathogenesis.

Abstract
UNLABELLED The proinflammatory cytokine interleukin-1β (IL-1β) is involved in the initiation and progression of osteoarthritis (OA) by stimulating the expression of matrix-degrading proteinases, such as a disintegrin metalloproteinase with thrombospondin motifs-5 (ADAMTS-5), a key player in OA pathogenesis. However, how IL-1β induces ADAMTS-5 overexpression is poorly understood. We demonstrate that IL-1β regulates ADAMTS-5 expression by suppressing microRNA-30a (miR-30a). Bioinformatics was performed to predict miRNAs targeting ADAMTS-5. miR-30a inhibited ADAMTS-5 expression by directly targeting its 3'-untranslated region. miR-30a expression was downregulated in OA patients and was negatively correlated with ADAMTS-5 expression and positively correlated with Hospital for Special Surgery (HSS) scores. IL-1β suppressed miR-30a expression by recruiting the activator protein (AP-1) transcription factor c-jun/c-fos to the miR-30a promoter. IL-1β-induced c-jun/c-fos expression regulated ADAMTS-5 expression and cartilage matrix degradation via miR-30a in human chondrocytes. These data indicate that the IL-1β/AP-1/miR-30a/ADAMTS-5 pathway contributes to IL-1β-induced cartilage matrix degradation in human OA chondrocytes. miR-30a may act as a pivotal regulator of cartilage homeostasis and a potential diagnostic and therapeutic target for OA. KEY MESSAGES ADAMTS-5 was identified as a novel direct target of miR-30a. IL-1β suppresses miR-30a expression through activation of AP-1 (c-jun/c-fos). AP-1/miR-30a is essential for IL-1β-induced ADAMTS-5 upregulation in OA. Downregulation of miR-30a in OA is negatively correlated with ADAMTS-5 expression.

Turkoglu SA, Kockar F. SP1 and USF differentially regulate ADAMTS1 gene expression under normoxic and hypoxic conditions in hepatoma cells. Gene 2016; 575:48-57. [PMID: 26299656 DOI: 10.1016/j.gene.2015.08.035] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2015] [Revised: 06/30/2015] [Accepted: 08/18/2015] [Indexed: 01/28/2023]
Abstract
ADAM metallopeptidase with thrombospondin type I motif, 1 (ADAMTS1) that has both antiangiogenic and aggrecanase activity was dysregulated in many pathophysiologic circumstances. However, there is limited information available on the transcriptional regulation of ADAMTS1 gene. Therefore, this study mainly aimed to identify regulatory regions important for the regulation of ADAMTS1 gene under normoxic and hypoxic conditions in human hepatoma cells (HEP3B). Cultured HEP3B cells were exposed to normal oxygen condition, and Cobalt chloride (CoCl2) induced the hypoxic condition, which is an HIF-1 inducer. The cocl2-induced hypoxic condition led to the induced ADAMTS1 mRNA and protein expression in Hepatoma cells. Differential regulation of SP1 and USF transcription factors on ADAMTS1 gene expression was determined by transcriptional activity, mRNA and protein level of ADAMTS1 gene. Ectopic expression of SP1 and USF transcription factors resulted in the decrease in ADAMTS1 transcriptional activity of all promoter constructs consistent with mRNA and protein level in normoxic condition. However, overexpression of SP1 and USF led to the increase of ADAMTS1 gene expressions at mRNA and protein level in hypoxic condition. On the other hand, C/EBPα transcription factor didn't show any statistically significant effect on ADAMTS1 gene expression at mRNA, protein and transcriptional level under normoxic and hypoxic condition.

Abstract
Hepatic progenitor/oval cell (OC) activation occurs when hepatocyte proliferation is inhibited and is tightly associated with the fibrogenic response during severe liver damage. Connective tissue growth factor (CTGF) is important for OC activation and contributes to the pathogenesis of liver fibrosis. By using the Yeast Two-Hybrid approach, we identified a disintegrin and metalloproteinase with thrombospondin repeat 7 (ADAMTS7) as a CTGF binding protein. In vitro characterization demonstrated CTGF binding and processing by ADAMTS7. Moreover, Adamts7 mRNA was induced during OC activation, after the implantation of 2-acetylaminofluorene with partial hepatectomy in rats or on feeding a 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) diet in mice. X-Gal staining showed Adamts7 expression in hepatocyte nuclear factor 4α(+) hepatocytes and desmin(+) myofibroblasts surrounding reactive ducts in DDC-treated Adamts7(-/-) mice carrying a knocked-in LacZ gene. Adamts7 deficiency was associated with higher transcriptional levels of Ctgf and OC markers and enhanced OC proliferation compared to Adamts7(+/+) controls during DDC-induced liver injury. We also observed increased α-smooth muscle actin and procollagen type I mRNAs, large fibrotic areas in α-smooth muscle actin and Sirius red staining, and increased production of hepatic collagen by hydroxyproline measurement. These results suggest that ADAMTS7 is a new protease for CTGF protein and a novel regulator in the OC compartment, where its absence causes CTGF accumulation, leading to increased OC activation and biliary fibrosis.

Abstract
Altered expression of ADAMTS5 is associated with human carcinogenesis and tumor progression. However, the role of ADAMTS5 in hepatocellular carcinoma (HCC) is unclear. This study analyzed ADAMTS5 expression in HCC tissues and tested for association with clinicopathological and survival data from HCC patients and then explored the role of ADAMTS5 in HCC cells in vitro. Paraffin blocks from 48 HCC patients were used to detect ADAMTS5 and vascular endothelial growth factor (VEGF) expression and microvessel density (MVD). A normal liver cell line and HCC cell lines were used to detect ADAMTS5 expression and for ADAMTS5 manipulation. ADAMTS5 cDNA was stably transfected into HCC cells and ADAMTS5 expression assessed by Western blot analysis. Tumor cell-conditioned growth medium was used to assess human umbilical vein endothelial cell migration and Matrigel tube formation. Xenograft assay was performed to determine the role of ADAMTS5 in vivo. The data showed that the expression of ADAMTS5 was reduced in HCC, which was inversely associated with VEGF expression, MVD, and tumor size and associated with poor overall survival of HCC patients. Lentivirus-mediated ADAMTS5 expression significantly inhibited tumor angiogenesis by downregulating in vitro expression of VEGF and inhibiting migration and tube formations, and also inhibited tumor growth and VEGF expression and reduced MVD in vivo in a mouse xenograft model. Taken together, these results suggest that ADAMTS5 plays a role in suppression of HCC progression, which could be further studied as a promising novel therapeutic target and a potential prognostic marker in HCC.

Abstract
The tissue inhibitors of metalloproteinases (TIMPs) are proteins that specifically inhibit the proteolytic activity of the matrix metalloproteinases (MMPs). TIMP-3, the only member of the TIMPs that can tightly bind to the extracellular matrix, has been identified as a unique tumor suppressor that demonstrates the ability to inhibit tumor angiogenesis, invasion, and metastasis. This study aimed to detect the expression of TIMP-3 in hepatocellular carcinoma (HCC) and investigate the association between TIMP-3 expression and its clinicopathological significance in HCC patients. In the current study, reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting of HCC cell lines and one-step quantitative reverse transcription PCR (qPCR) and immunohistochemistry (IHC) analyses in HCC tissues were performed, to characterize the TIMP-3 expression. Kaplan-Meier survival and Cox regression analyses were utilized to evaluate the prognosis of 101 HCC patients. The results showed that the expression of TIMP-3 in HCC was significantly decreased relative to that of non-cancerous cells and tissues. Furthermore, the TIMP-3 expression was statistically associated with malignant behaviors of HCC, including portal vein invasion (p = 0.036) and lymph node metastasis (p = 0.030). Cox regression analysis revealed that TIMP-3 expression was an independent prognostic factor for disease-free survival (p = 0.039) and overall survival (p = 0.049). These data indicate that TIMP-3 expression is a valuable prognostic biomarker for HCC and that TIMP-3 expression suggests a favorable prognosis for HCC patients.

Abstract
CONTEXT Polycystic ovary syndrome (PCOS) is the most common cause of dysfunctional ovulation-affecting female fertility. A disintegrin and metalloproteinase with thrombospondin-like motifs (ADAMTS-1) is required for normal ovulation and subsequent fertilization, and the expression of ADAMTS-1 may be altered in PCOS granulosa cell (GC)-reflecting abnormalities in ovulatory signaling. OBJECTIVE The purpose of this paper is to analyze the differential expression of ADAMTS-1 in PCOS patients associated with impaired oocyte quality. DESIGN AND SETTING A prospective comparative experimental study was performed at a clinical reproductive medicine center. PATIENTS Women with PCOS (n = 40) and normovulatory controls (n = 40) undergoing controlled ovarian hyperstimulation and in vitro fertilization were recruited in our study. MAIN OUTCOME MEASURES Differential expression of ADAMTS-1 in GCs was analyzed with immunocytochemistry in PCOS patients and normal controls, and ADAMTS-1 mRNA expression was quantified by RT-PCR. Furthermore, the correlation between ADAMTS-1 mRNA and oocyte quality was analyzed. RESULTS The expression of ADAMTS-1 was decreased in PCOS patients compared with normally ovulating women and was closely related to lower oocyte recovery, oocyte maturity, and fertilization rate. CONCLUSION Our study provides evidence that the dysregulated expression of ADAMTS-1 in PCOS may influence oocyte quality-via GCs-oocyte paracrine and endocrine mechanism.
