Gonadotropin-releasing hormone antagonist associated with lower cardiovascular risk compared with gonadotropin-releasing hormone agonist in prostate cancer: A nationwide cohort and in vitro study. Prostate 2021; 81:902-912. [PMID: 34196430 DOI: 10.1002/pros.24187] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 05/29/2021] [Accepted: 06/07/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND We aimed to determine whether cardiovascular (CV) risk in patients with prostate cancer (PCa) differs between those who receive gonadotropin-releasing hormone (GnRH) agonist (GnRHa) therapy and those who receive GnRH antagonist therapy. METHODS Using the Taiwan National Health Insurance Research Database, we analyzed data by comparing 666 participants receiving GnRH antagonists and 1332 propensity score-matched participants treated with GnRHa in a 1:2 fashion during the period from May 1, 2015, to September 30, 2018. Cox proportional-hazards models were used to estimate the treatment effect on CV outcomes. Furthermore, we conducted an in vitro study to investigate the effect of a GnRHa (leuprolide) or a GnRH antagonist (degarelix) on matrix metalloproteinase-9 (MMP-9) expression and invasion ability in THP-1 differentiated macrophages. RESULTS GnRH antagonist therapy was associated with a lower risk of composite CV events of myocardial infarction, ischemic stroke, or CV death (hazard ratio [HR], 0.48; 95% confidence interval [CI], 0.25-0.90) than GnRHa therapy, with a mean follow-up period of 1.21 years. Significantly lower risks of CV death (HR, 0.21; 95% CI, 0.06-0.70) and all-cause mortality (HR, 0.77; 95% CI, 0.61-0.97) were observed in the GnRH antagonist group. In the in vitro study, leuprolide, but not degarelix, significantly increased the expression of MMP-9 activity and the invasive ability of THP-1 differentiated macrophages through gelatin zymography and the matrix invasion assay, respectively. CONCLUSION GnRH antagonists were associated with reduced risk CV events compared with the GnRHa among patients with PCa, which may be through effects on macrophages.

Abstract
The goal of this research was to evaluate the plasma concentration of MMP-9 and its tissue inhibitor (TIMP-1) in different clinical conditions. It included several groups of subjects: 31 overweight subjects; 91 obese adults divided into two subgroups according to the BMI value (BMI 30-35 Kg/m2 and BMI > 35 Kg/m2); 90 subjects with metabolic syndrome (MS) divided into two subgroups (with and without diabetes mellitus); 100 subjects with preclinical carotid atherosclerosis (PCA) divided according to the number of cardiovascular risk factors and to the insulin resistance degree; 48 subjects with obstructive sleep apnoea syndrome (OSAS) divided according to the apnoea/hypopnea index (AHI); 27 subjects with chronic kidney disease (CKD) on conservative management; 31 subjects with CKD on regular haemodialysis treatment. We have found a significant increase of MMP-9 and TIMP-1 in overweight subjects, in obese adult and in MS subjects. In obese adults, the behaviour of these two parameters was not influenced by the degree of obesity, while in the group of MS subjects both these parameters were clearly influenced by the presence of diabetes mellitus. In subjects with PCA, we observed an increase of MMP-9 associated with a significant decrease of TIMP-1; the same trend was found by subdividing the entire group in accordance with the number of cardiovascular risk factors and with the insulin resistance degree. In subjects with OSAS, we noted an increase in MMP-9 and TIMP-1; this increase was more evident in subjects with OSAS having AHI > 30. In individuals with CKD on conservative and haemodialysis treatment we have found, at baseline, a marked increase in MMP-9 and a significant decrease of TIMP-1. In dialyzed subjects, after a standard dialysis session was noted, a significant increase in MMP-9 was associated with a further decrease in TIMP-1.

Abstract
Historically, there has been a scarcity of evidence-based topical therapy to hasten the healing of diabetic foot ulcers. But recently new evidence-based treatments have emerged from multicentre, randomised, controlled trials. This article highlights those trials, and describes the current pharmacological management of the diabetic foot ulcer and the advances that have been made in wound therapy to date. It provides an overview of topical and systemic pharmacotherapies in current use and those in development for future use in managing the diabetic foot. For each treatment, proposed mechanisms of action and evidence available to support their clinical use are presented. There is supporting randomised, controlled evidence for sucrose octasulfate in the treatment of neuro-ischaemic ulcers, and multi-layered patch of autologous leucocytes, platelets and fibrin in ulcers with or without ischaemia. There is also evidence for placentally derived products and for topical and systemic oxygen therapy in the healing of diabetic foot ulcers. Growth factors, bio-engineered tissues, stem cell therapy, gene therapy and peptide therapy also have some supporting evidence in the healing of diabetic foot ulcers. Nonsurgical debriding agents may be useful when the optimum approach of sharp debridement is not possible, and immunomodulators may be helpful for their antimicrobial effects, but robust data is still required to strengthen the case for general use. The review does not cover antimicrobials as their primary role are as anti-infectives and not in wound healing. The development of nanotechnology has created a means of prolonging the bioavailability of target molecules at the wound site, with the use of glass/hydrogel nanoparticles, polyethylene glycol and hyaluronic acid. Looking forward, novel therapies, including traction force-activated payloads, local delivery of short-interfering RNA and finally hydrogels incorporating bioactive agents or cells may provide possibilities for pharmacotherapy in the future.

CELL JOURNAL 2017; 19:559-568.

Abstract
Objective Recent studies have reported dysregulated expression of matrix metalloproteinases (MMPs), especially
MMP-2, MMP-9, tissue inhibitor of metalloproteinase-1, -2 (TIMP-1, TIMP-2), and extracellular matrix metalloproteinase
inducer (EMMPRIN/CD147) in activated macrophages of patients with inflammatory diseases. Therefore, MMP-2,
MMP-9, and their regulators may represent a new target for treatment of inflammatory diseases. Probiotics, which
are comprised of lactic acid bacteria, have the potential to modulate inflammatory responses. In this experimental
study, we investigated the anti-inflammatory effects of cell-free supernatants (CFS) from Lactobacillus acidophilus (L.
acidophilus) and L. rhamnosus GG (LGG) in phorbol myristate acetate (PMA)-differentiated THP-1 cells.
Materials and Methods In this experimental study, PMA-differentiated THP-1 cells were treated with CFS from L.
acidophilus, LGG and uninoculated bacterial growth media (as a control). The expression of MMP-2, MMP-9, TIMP-1,
and TIMP-2 mRNAs were determined using real-time quantitative reverse transcription polymerase chain reaction (RT-
PCR). The levels of cellular surface expression of CD147 were assessed by flow cytometry, and the gelatinolytic activity
of MMP-2 and MMP-9 were determined by zymography.
Results Our results showed that CFS from both L. acidophilus and LGG significantly inhibited the gene expression of
MMP-9 (P=0.0011 and P=0.0005, respectively), increased the expression of TIMP-1 (P<0.0001), decreased the cell
surface expression of CD147 (P=0.0307 and P=0.0054, respectively), and inhibited the gelatinolytic activity of MMP-9
(P=0.0003 and P<0.0001, respectively) in PMA-differentiated THP-1 cells. Although, MMP-2 expression and activity
and TIMP-2 expression remained unchanged.
Conclusion Our results indicate that CFS from L. acidophilus and LGG possess anti-inflammatory properties and can
modulate the inflammatory response.

Abstract
Venous leg ulcers are common in subjects with chronic venous insufficiency. The increased intraluminal pressure causes alteration of the skin microcirculation, leukocyte activation and release of proteolytic enzymes leading to ulceration. An impaired expression and activity of matrix metalloproteases (MMPs) and their tissue inhibitors (TIMPs) might influence extracellular matrix degradation and deposition in chronic venous ulcers with the failure of the healing process. Our aim was to evaluate plasma concentration of gelatinases (MMP-2 and MMP-9) and their inhibitors (TIMP-1 and TIMP-2) in subjects with venous leg ulcers before and after the compression therapy. We enrolled 36 subjects (12 men and 24 women, mean age 67.38 ± 12.7 yrs) with non-infected venous leg ulcers (CEAP C6), which underwent a color Duplex scan examination of the veins and arteries of the inferior limbs and were treated with a multi-layer bandaging system. The ulcer healing was obtained in 23 subjects only (9 men and 14 women). We evaluated, on fasting venous blood, the plasma levels of MMP-2, MMP-9, TIMP-1 and TIMP-2 using ELISA kit, before and after the treatment. We observed a significant increase in plasma concentration of gelatinases and their inhibitors and in MMP-2/TIMP-2 ratio in subjects with leg ulcers in comparison with normal controls. In subjects with healed ulcers we found a decrease in MMP-9 and TIMP-1 levels and in MMP-2/TIMP-2 ratio compared to the baseline values, although higher levels of all the examined parameters in comparison with normal controls. In conclusion, plasma MMPs profile is impaired in subjects with venous leg ulcers and it improves after the healing, persisting anyway altered in respect to healthy controls.

Cardiac troponin I exacerbates myocardial ischaemia/reperfusion injury by inducing the adhesion of monocytes to vascular endothelial cells via a TLR4/NF-κB-dependent pathway. Clin Sci (Lond) 2016; 130:2279-2293. [PMID: 27682003 DOI: 10.1042/cs20160373] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2016] [Revised: 06/29/2016] [Accepted: 09/28/2016] [Indexed: 12/20/2022]
Abstract
Cardiac troponin I (cTnI), a biomarker for myocardial damage and risk stratification, may be involved in the pathogenesis of cardiovascular diseases, which was ascribed to the effect of cTnI auto-antibodies. Whether or not cTnI itself has a direct impact on acute myocardial injury is unknown. To exclude the influence of cTnI antibody on the cardiac infarct size, we studied the effect of cTnI shortly after myocardial ischaemia-reperfusion (I/R) injury when cTnI antibodies were not elevated. Pretreatment with cTnI augmented the myocardial infarct size caused by I/R, accompanied by an increase in inflammatory markers in the blood and myocardium. Additional experiments using human umbilical vein endothelial cells (HUVECs) showed that the detrimental effect of cTnI was related to cTnI-induced increase in vascular cell adhesion molecule-1 (VCAM-1) expression and VCAM-1 mediated adhesion of human monocytes (THP-1) to HUVECs, which could be neutralized by VCAM-1 antibody. Both toll-like receptor 4 (TLR4) and nuclear factor-κB (NF-κB) were involved in the signalling pathway, because blockade of either TLR4 or NF-κB inhibited the cTnI's effect on VCAM-1 expression and adhesion of monocytes to endothelial cells. Moreover, TLR4 inhibition reduced cTnI-augmented cardiac injury in rats with I/R injury. We conclude that cTnI exacerbates myocardial I/R injury by inducing the adhesion of monocytes to vascular endothelial cells via activation of the TLR4/NF-κB pathway. Inhibition of TLR4 may be an alternative strategy to reduce cTnI-induced myocardial I/R injury.

Abstract
We investigated whether cilostazol, an activator of cyclic adenosine monophosphate (cAMP)-dependent intracellular signaling, could inhibit ultraviolet B (UVB) irradiation-induced photoaging in HR-1 hairless mice. Cilostazol decreased wrinkle formation and skin thickness in UVB-irradiated mice, as well as increased staining of collagen fibers and inhibition of reactive oxygen species (ROS) formation in the skin. Moreover, the proteolytic activities of gelatinase matrix metalloproteinase (MMP)-9 and collagenase MMP-3 were significantly decreased in UVB-irradiated mice treated with cilostazol. Western blotting showed that UVB-induced activation of p38 mitogen-activated protein kinases (MAPK) and nuclear factor (NF)-κB was significantly inhibited by cilostazol, whereas the activation of Akt was significantly enhanced by cilostazol. Confirmation of localized protein expression in the skin revealed marked p38 MAPK and NF-κB activation that was mainly detected in the dermis. Marked Akt activation was mainly detected in the epidermis. Our results suggest that cilostazol may have anti-photoaging effects on UVB-induced wrinkle formation by maintaining the extracellular matrix density in the dermis, which occurs via regulation of ROS and related p38 MAPK and NF-κB signaling, and subsequent down-regulation of MMPs. Therefore, cilostazol may protect against photoaging-induced wrinkle formation.

Abstract
Matrix metalloproteinases (MMPs) are a family of zinc dependent endopeptidases whose main function is to degrade and deposit structural proteins within the extracellular matrix (ECM). A dysregulation of MMPs is linked to vascular diseases. MMPs are classified into collagenases, gelatinases, membrane-type, metalloelastase, stromelysins, matrilysins, enamelysins, and unclassified subgroups. The production of MMPs is stimulated by factors such as oxidative stress, growth factors and inflammation which lead to its up- or down-regulation with subsequent ECM remodeling. Normally, excess activation of MMPs is controlled by their endogenous inhibitors, tissue inhibitors of metalloproteinases (TIMPs). An imbalance of MMPs and TIMPs has been implicated in hypertension, atherosclerotic plaque formation and instability, aortic aneurysms and varicose vein wall remodeling. Also, recent evidence suggests epigenetic regulation of some MMPs in angiogenesis and atherosclerosis. Over the years, pharmacological inhibitors of MMPs have been used to modify or prevent the development of the disease with some success. In this review, we discuss recent advances in MMP biology, and their involvement in the manifestation of vascular disease.

Abstract
Monocyte recruitment and invasion play critical roles in the initiation and progression of atherosclerosis. The reduction in monocyte adhesion and infiltration is thought to exert antiatherosclerotic effects. Curcumin, demethoxycurcumin (DMC), and bisdemethoxycurcumin (BDMC) are the major active components of curcuminoids and exhibit several biological activities, including anti-inflammatory, anticarcinogenic, and hypocholesterolemic activities. The aim of this study was to investigate the antiatherogenic effects and mechanisms of curcuminoids during monocyte to macrophage differentiation. The results showed that curcumin, DMC, and BDMC (20 μM) suppressed matrix invasion from 100.0 ± 5.0% to 24.8 ± 1.4%, 26.6 ± 2.9%, and 33.7 ± 1.7%, respectively, during PMA-induced THP-1 differentiation. We found that curcuminoids significantly reduced PMA-induced CD11b and MMP-9 expression by THP-1 cells. Production of reactive oxygen species (ROS) induced by PMA (126.7 ± 2.1%) was markedly attenuated by curcumin, DMC, and BDMC to 99.5 ± 7.8%, 87.8 ± 8.2%, and 89.8 ± 7.6%, respectively, resulting in the down-regulation of CD11b and MMP-9 expression. We demonstrated that curcuminoids inhibited NADPH oxidase through the down-regulation of NOX2 expression and the reduction of p47phox membrane translocation. Moreover, we found involvement of PKCδ in the PMA-induced NOX2, CD11b, and MMP-9 mRNA expression. Curcumin, DMC, and BDMC decreased the active form of PKCδ protein stimulated by PMA in THP-1 cells. Overall, our results reveal that curcuminoids suppress matrix invasion through the inhibition of the PKCδ/NADPH oxidase/ROS signaling pathway during monocyte-macrophage differentiation.

Abstract
OBJECTIVE The role of matrix metalloproteinases (MMPs) in tissue degradation has become evident in many diseases and great interest therefore exists in the pharmacological control of the activity of these enzymes. This study evaluated the effect of caffeic acid phenethyl ester (CAPE) on the production of MMPs and their inhibitor (TIMP) in monocytes activated by lipopolysaccharide (LPS). DESIGN The human monocytic cell line (THP-1) was treated with non-cytotoxic concentrations of CAPE (10 and 60μM) combined with 1μg/mL of LPS. The gene expression of MMP-1, MMP-9 and TIMP-1 was evaluated by quantitative real-time polymerase chain reaction. The protein secretion into the culture medium was assessed via enzyme-linked immunosorbent assay and the gelatinolytic activity of MMP-9 by zymography. RESULTS CAPE, especially at the highest concentration, down-regulated MMP-1 and MMP-9 gene expression but up-regulated the gene expression of TIMP-1. Furthermore, CAPE reduced the secreted protein level of MMP-1 and MMP-9 as well as the gelatinolytic activity of MMP-9. CONCLUSION CAPE was able to inhibit the gene expression, production and the activity of MMPs induced by LPS and also increased the gene expression of TIMP-1. The present observations suggest that CAPE exerted a positive effect on the regulatory mechanism between MMPs and TIMP, which is important for the control of different diseases.

Abstract
Atherosclerosis is an inflammatory process that involves activation of matrix metalloproteinases (MMPs); MMPs degrade collagen and allow for smooth-muscle cell migration within a vessel. Moreover, this begets an accumulation of other cellular material, resulting in occlusion of the vessel and ischemic events to tissues in need of nutrients. Homocysteine has been shown to activate MMPs via an increase in oxidative stress and acting as a signaling molecule on receptors like the peroxisome proliferator activated receptor-γ and N-methyl-D-aspartate receptor. Nitric oxide has been shown to be beneficial in some cases of deactivating MMPs. However, in other cases, it has been shown to be harmful. Further studies are warranted on the scenarios that are beneficial versus destructive. Hydrogen sulfide (H2S) has been shown to decrease MMP activities in all cases in the literature by acting as an antioxidant and vasodilator. Various MMP-knockout and gene-silencing models have been used to determine the function of the many different MMPs. This has allowed us to discern the role that each MMP has in promoting or alleviating pathological conditions. Furthermore, there has been some study into the MMP polymorphisms that exist in the population. The purpose of this review is to examine the role of MMPs and their polymorphisms on the development of atherosclerosis, with emphasis placed on pathways that involve nitric oxide, hydrogen sulfide, and homocysteine.

Abstract
In coronary arteries, plaque disruption, the major acute clinical manifestations of atherosclerosis, leads to a subsequent cardiac event, such as acute myocardial infarction (AMI) and unstable angina pectoris (UA). Numerous reports have shown that high expression of MMP-9 (matrix metalloproteinase-9), MMP-13 (matrix metalloproteinase-13) and EMMPRIN (extracellular matrix metalloproteinase induce) in monocyte/macrophage results in the plaque progression and destabilization. Curcumin exerts well-known anti-inflammatory and antioxidant effects and probably has a protective role in the atherosclerosis. The purpose of our study was to investigate the molecular mechanisms by which curcumin affects MMP-9, MMP13 and EMMPRIN in PMA (phorbol 12-myristate 13-acetate) induced macrophages. Human monocytic cells (THP-1 cells) were pretreated with curcumin or compound C for 1 h, and then induced by PMA for 48 h. Total RNA and proteins were collected for real-time PCR and Western blot analysis, respectively. In the present study, the exposure to curcumin resulted in attenuated JNK, p38, and ERK activation and decreased expression of MMP-9, MMP-13 and EMMPRIN in PMA induced macrophages. Moreover, we demonstrated that AMPK (AMP-activated protein kinase) and PKC (Protein Kinase C) was activated by PMA during monocyte/macrophage differentiation. Furthermore, curcumin reversed PMA stimulated PKC activation and suppressed the chronic activation of AMPK, which in turn reduced the expression of MMP-9, MMP-13 and EMMPRIN. Therefore, it is suggested that curcumin by inhibiting AMPK-MAPK (mitogen activated protein kinase) and PKC pathway may led to down-regulated EMMPRIN, MMP-9 and MMP-13 expression in PMA-induced THP-1 cells.

Abstract
Diabetic patients are at high risk of foot ulcerations that may lead to limb amputations with important socio-economic impact. Peripheral vascular disease may be frequently associated in diabetes mellitus type II with its main symptom, intermittent claudication. Many studies reported the known efficacy of cilostazol in treating vascular claudication. Metalloproteinase-9 (MMP-9) seems to be a biochemical marker implicated in chronic wounds and in particular in diabetic foot ulcers. Cilostazol appears to have a lowering effect on MMP-9 levels and this may suggest a beneficial effect in order to prevent or retard the onset of foot ulcer in diabetic patients. In our study, two groups of diabetic patients with peripheral vascular disease were divided into two groups according to the presence of claudication in order to receive cilostazol. Group A (31 patients without claudication) were not eligible to receive cilostazol whereas Group B (47 patients with claudication) received cilostazol administration for 24 weeks (100 mg orally twice daily). Median follow up was of 16 months. During the follow up, 4·25% of patients of Group B and 35·48% of patients of Group A (P < 0·01) showed onset of foot ulceration. Although further randomised and controlled studies are required cilostazol seems to show beneficial effects for primary prevention of diabetic foot ulcers.

Abstract
Endoplasmic reticulum (ER) stress causes impairment of the intracellular protein synthesis machinery, affecting various organ functions and homeostasis systems, including immunity. We found that ER stress induced by the N-linked glycosylation inhibitor, tunicamycin, caused susceptibility to apoptosis in the human monocytic cell line, THP-1 cells. Importantly, prior to tunicamycin-induced apoptosis, the proinflammatory response to toll-like receptor (TLR) 4 ligand lipopolysaccharide (LPS) stimulation was attenuated with respect to the expression of the proinflammatory cytokines. This impaired expression of proinflammatory cytokines was a consequence of the inhibition of NF-κB activation. Moreover, tunicamycin-induced ER stress disturbed the differentiation of THP-1 cells into macrophages induced by phorbol-12-myristate-13-acetate treatment. We also confirmed that ER stress affected the response of primary human monocytes to TLR ligand and their ability to differentiate into macrophages. These data suggest that ER stress imposes an important pathological insult to the immune system, affecting the crucial functions of monocytes.

Abstract
Stroke prevention efforts typically focus on either ischemic or hemorrhagic stroke. This approach is overly simplistic due to the frequent coexistence of ischemic and hemorrhagic cerebrovascular disease. This coexistence, termed “mixed cerebrovascular disease”, offers a conceptual framework that appears useful for stroke prevention strategies. Mixed cerebrovascular disease incorporates clinical and subclinical syndromes, including ischemic stroke, subclinical infarct, white matter disease of aging (leukoaraiosis), intracerebral hemorrhage, and cerebral microbleeds. Reliance on mixed cerebrovascular disease as a diagnostic entity may assist in stratifying risk of hemorrhagic stroke associated with platelet therapy and anticoagulants. Animal models of hemorrhagic cerebrovascular disease, particularly models of cerebral amyloid angiopathy and hypertension, offer novel means for identifying underlying mechanisms and developing focused therapy. Phosphodiesterase (PDE) inhibitors represent a class of agents that, by targeting both platelets and vessel wall, provide the kind of dual actions necessary for stroke prevention, given the spectrum of disorders that characterizes mixed cerebrovascular disease.
