Oxidation Study of Oleocanthal and Oleacein Induced by Oxone.

A selective Oxone-induced oxidation of oleocanthal and oleacein, the two main secoiridoids of olive oil, to their bis-oxidized products is described. This protocol is based on a Baeyer-Villiger mechanism and the concentration of Oxone in the final solution. The bis-oxidation of the aldehydic compounds could be extended for the synthesis of various semisynthetic analogs. The obtained acids exhibit strong antioxidant activity, being efficient free radical scavengers.

An empirical investigation of the nexus among renewable energy, financial openness, economic growth, and environmental degradation in selected ASEAN economies.

This study investigates the relationship between economic growth, renewable energy consumption, financial openness, and environmental degradation in selected ASEAN (Association of Southeast Asian Nations) countries (Cambodia, Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam) from 1996 to 2018. We aim to analyze how macroeconomic situation, energy-related factors, and financial determinants contribute to environmental deprivation in selected countries whose growth has recently been substantial. To address this issue, we employ second-generation panel data regression models and quantiles with fixed-effects estimators. Initially, the cointegration analysis supports a long-run association between the variables of our interest. Empirical findings confirm the environmental Kuznets curve hypothesis, but it seems valid only for Singapore. Moreover, results highlight the ecological role of renewable energy for ASEAN countries to achieve Sustainable Development Goals, such as transitioning to a low-carbon economy and reducing air pollution. On the contrary, financial openness is a cause that positively influences CO2 emissions. This research offers practical policy recommendations for many countries, including the ASEAN economies, to attain sustainable development.

Next-generation sequencing reveals altered gene expression and enriched pathways in triple-negative breast cancer cells treated with oleuropein and oleocanthal.

Triple-negative breast cancer (TNBC) is a subtype of breast cancer characterized by poor prognosis and limited treatment options. Oleuropein and oleocanthal are bioactive chemicals found in extra-virgin olive oil; they have been shown to have anti-cancer potential. In this study, we examined the inhibitory effects of these two natural compounds, on MDA-MB-231 and MDA-MB-468 TNBC cell lines. The human TNBC MDA-MB-231 and MDA-MB-468 cell lines were treated with oleuropein or oleocanthal at ranging concentrations for 48 h. After determining the optimum concentration to reach IC50, using the sulforhodamine B assay, total RNA was extracted after 12, 24, and 48 h from treated and untreated cells. Poly(A)-RNA selection was conducted, followed by library construction and RNA sequencing. Differential gene expression (DEG) analysis was performed to identify DEGs between treated and untreated cells. Pathway analysis was carried out using the KEGG and GO databases. Oleuropein and oleocanthal considerably reduced the proliferation of TNBC cells, with oleocanthal having a slightly stronger effect than oleuropein. Furthermore, multi-time series RNA sequencing showed that the expression profile of TNBC cells was significantly altered after treatment with these compounds, with temporal dynamics and groups of genes consistently affected at all time points. Pathway analysis revealed several significant pathways associated with TNBC, including cell death, apoptotic process, programmed cell death, response to stress, mitotic cell cycle process, cell division, and cancer progression. Our findings suggest that oleuropein and oleocanthal have potential therapeutic benefits for TNBC and can be further investigated as alternative treatment options.

Pediatric renal transplantation-A UNOS database analysis of donor-recipient size mismatch.

BACKGROUND: We used the BSAi (Donor BSA/Recipient BSA) to assess whether transplanting a small or large kidney into a pediatric recipient relative to his/her size influences renal transplant outcomes. METHODS: We included 14 322 single-kidney transplants in pediatric recipients (0-17 years old) (01/2000-02/2020) from the United Network for Organ Sharing database. We divided cases into four BSAi groups (BSAi ≤ 1, 1 < BSAi ≤ 2, 2 < BSAi ≤ 3, BSAi > 3). RESULTS: There were no differences concerning delayed graft function (DGF) or primary non-function (PNF) rates, whether the grafts were from living or brain-dead donors. In both transplants coming from living donors and brain-dead donors, cases with BSAi > 3 and cases with 2 < BSAi ≤ 3 had similar graft survival (p = .13 for transplants from living donors, p = .413 for transplants from brain-dead donors), and both groups had longer graft survival than cases with 1 < BSAi ≤ 2 and cases with BSAi ≤ 1 (p < .001). The difference in 10-year graft survival rates between cases with BSAi > 3 and cases with BSAi ≤ 1 reached around 25% in both donor types. The better graft survival in transplants with BSAi > 2 was confirmed in multivariable analysis. CONCLUSIONS: There is no significant impact of donor-recipient size mismatch on DGF and PNF rates in pediatric renal transplants. However, graft survival is significantly improved when the donor's size is more than twice the pediatric recipient's size.

Time-Related Evidence of Intestinal Oxidative Stress in Obstructive Jaundice-Induced Rats.

INTRODUCTION: Obstructive jaundice is known to affect intestinal permeability and facilitate bacterial translocation through related mechanisms. This study was conducted to evaluate the alterations concerning blood biochemistry and levels of several markers of oxidative stress (OS) in blood and intestinal mucosa caused by obstructive jaundice and how these fluctuate over time, in order to further explore the possibility of intervening in the OS path in future experiments. METHODS: A total of 54 albino Wistar rats were randomly divided into three groups (control, sham operated, and bile duct ligation) and sacrificed at specific time intervals (12 h and 2, 7, and 14 days). The intestinal barrier function was evaluated by measuring endotoxin levels in portal, aortic, and peripheral blood. Also, basic biochemical parameters were simultaneously measured in peripheral blood. Tissue samples collected from the terminal ileum were homogenized for determining the OS markers, lipid peroxidation, and protein-free radical-induced oxidation. RESULTS: We designed this experiment to examine the alterations in enteric mucosa primarily in relation to OS in a period of 14 days. During this time period, we investigated in specific time intervals not only OS fluctuations but also other liver function parameters, as well as CRP and endotoxin levels. The alterations were monitored in relation to time after bile duct ligation. CONCLUSION: Bile duct ligation in rats causes OS versus post-ligation time progression of the common bile duct. OS was increased by ∼50% compared to control/sham and peaked at 7 days and at least up to 14 days post-ligation. This phenomenon was accompanied with a deranging of liver function after ligation, as anticipated, but not in all measured parameters; biochemical and endotoxin levels followed the same pattern.

Exploring the Interaction of New Pyridoquinazoline Derivatives with G-Quadruplex in the c-MYC Promoter Region.

Novel amino-substituted pyridoquinazolinone derivatives have been designed and synthesized as potential c-MYC G-quadruplex (G4) ligands, employing an efficient methodology. All the new compounds exhibited moderate to good antiproliferative activity against the human osteosarcoma U2OS cell line. NMR and docking experiments revealed that the recently synthesized compounds interact with the Pu22 G-quadruplex in the c-MYC promoter region, establishing a 2:1 complex, with each molecule positioned over the tetrads at the 3'- and 5'-ends.

Disaggregated energy use and socioeconomic sustainability within OECD countries.

This study investigates the relationship between disaggregated energy use, human development, trade openness, economic growth, urbanization, and sustainability index in OECD countries from 2014 to 2019. Static, quantile, and dynamic panel data approaches are employed. The findings reveal that fossil fuels such as petroleum, solid fuels, natural gas, and coal decrease sustainability. On the contrary, alternative sources such as renewable and nuclear energy seem to contribute positively to sustainable socioeconomic development. It is also interesting to note that alternative energy sources strongly influence socioeconomic sustainability in the lower and upper quantiles. Also, the human development index and trade openness improve sustainability, while urbanization seems to be an obstacle in complying with sustainability goals within OECD countries. Policymakers should revisit their strategies toward sustainable development by mitigating fossil fuels and urbanization and promoting human development, trade openness, and alternative energy sources as drivers of economic progress.

Synthesis and Biological Evaluation of Resveratrol Methoxy Derivatives.

Resveratrol, a naturally occurring stilbene, exhibits numerous beneficial health effects. Various studies have demonstrated its diverse biological actions, including anti-oxidant, anti-inflammatory, and anti-platelet properties, thereby supporting its potential for cardio protection, neuroprotection, and anti-cancer activity. However, a significant limitation of resveratrol is its weak bioavailability. To overcome this challenge, multiple research groups have investigated the synthesis of new resveratrol derivatives to enhance bioavailability and pharmacological activities. Nevertheless, there are limited data on the effects of resveratrol derivatives on platelet function. Therefore, the objective of this study was to synthesize resveratrol methoxy derivatives and evaluate their anti-platelet and anti-proliferative activity. Platelet-rich plasma (PRP) obtained from healthy volunteers was utilized to assess the derivatives' ability to inhibit platelet aggregation induced by platelet activating factor (PAF), adenosine diphosphate (ADP), and thrombin receptor activating peptide (TRAP). Additionally, the derivatives' anti-tumor activity was evaluated against the proliferation of PC-3 and HCT116 cells. The results revealed that some methoxy derivatives of resveratrol exhibited comparable or even superior anti-platelet activity compared to the original compound. The most potent derivative was the 4'-methoxy derivative, which demonstrated approximately 2.5 orders of magnitude higher anti-platelet activity against TRAP-induced platelet aggregation, indicating its potential as an anti-platelet agent. Concerning in silico studies, the 4'-methyl group of 4'-methoxy derivative is oriented similarly to the fluorophenyl-pyridyl group of Vorapaxar, buried in a hydrophobic cavity. In terms of their anti-tumor activity, 3-MRESV exhibited the highest potency in PC-3 cells, while 3,4'-DMRESV and TMRESV showed the greatest efficacy in HCT116 cells. In conclusion, methoxy derivatives of resveratrol possess similar or improved anti-platelet and anti-cancer effects, thereby holding potential as bioactive compounds in various pathological conditions.

Synthesis and Biological Evaluation of 2-Substituted Quinazolin-4(3H)-Ones with Antiproliferative Activities.

Sixteen new 2-substituted quinazolines were synthesized using a straightforward methodology starting from 2-methoxybezoic acid or 3-methoxy-2-naphthoic acid. The anti-proliferative activity of the target compounds was evaluated against nine cancer cell lines. Additionally, all the compounds were screened for their potency and selectivity against a panel of 109 kinases and four bromodomains, using Differential Scanning Fluorimetry (DSF). Compound 17 bearing a 2-methoxyphenyl substitution along with a basic side chain displayed a remarkable profile against the majority of the tested cell lines.

Chemometrically Assisted Optimization of Pregabalin Fluorescent Derivatization Reaction with a Novel Xanthone Analogue and Validation of the Method for the Determination of Pregabalin in Bulk via a Plate Reader.

Quantitation of chromophore-free analytes is always a challenge. To this purpose, derivatization of the analyte constitutes a common strategy, leading to a product with a strong signal. In the current study, a novel xanthone analogue was utilized for the first time for the derivatization of pregabalin, a model analyte with a primary amine moiety that lacks a chromophore. The fact that only the xanthene-based derivative, formed after the derivatization reaction fluoresces, enables avoiding its chromatographic separation from the reagent and thus reducing the analysis time of a series of samples in 1-2 min via a plate reader. The reaction conditions were optimized via a central composite design (CCD), with fluorescence signal as the measure of the yield. The following factors that affect the derivatization reaction were chosen: (a) temperature, (b) reaction time, and (c) triethylamine solution volume used to drive the reaction to completion. After the identification of the optimal conditions, the method was validated according to ICH guidelines, using a fluorescence plate reader for signal measurement (λex = 540, λem = 615 nm). Finally, the newly developed high-throughput method was applied to the determination of drug content in pregabalin bulk.

High fascin-1 expression in colorectal cancer identifies patients at high risk for early disease recurrence and associated mortality.

BACKGROUND: Fascin is the main actin cross-linker protein that regulates adhesion dynamics and stabilizes cell protrusion, such as filopodia. In human cancer, fascin expression correlates with aggressive clinical features. This study aimed to determine the expression patterns of fascin-1 and assessed its prognostic significance in colorectal cancer. METHODS: One hundred eleven specimens of patients with primary resectable colorectal cancer were examined via immunohistochemistry for the expression of fascin-1, and the results were correlated with clinicopathological characteristics and survival data. RESULTS: Fascin-1 staining displayed strong intensity in the cytoplasm of the colorectal cancer cells and endothelial cells of tumor blood vessels. Moderate to high fascin-1 expression was associated with progressive anatomic disease extent (p < 0.001), higher T classification (p = 0.007), the presence of lymph node (p < 0.001) and distant metastasis (p = 0.002), high grade tumors (p = 0.002) and vascular invasion (p < 0.001). Patients displaying moderate and high fascin-1 expression demonstrated a significantly worse 5-year overall survival [HR; 3.906, (95%CI) = 1.250-12.195] and significantly worse 3-year progression-free survival [HR; 3.448, (95%CI) = 1.401-8.475] independent of other clinicopathological characteristics. Besides, high fascin-1 expression in early-stage cancer only was associated with a dismal prognosis. CONCLUSIONS: High fascin-1 expression in colorectal cancer is an independent negative prognostic factor for survival, increasing the risk for disease recurrence or death almost by sevenfold. Fascin-1 expression could be potentially utilized to identify high-risk patients prone to metastasis already in early-stage disease.

Adrenocortical Cancer: A 20-Year Experience of a Single Referral Center in Prognosis and Outcomes.

Adrenocortical carcinoma (ACC) is a rare but very aggressive endocrine malignancy with poor survival. Histopathology is important for diagnosis, while in some cases immunohistochemical markers and gene profiling of the resected tumor may be superior to current staging systems to determine prognosis. We aimed to present the 20-year experience at a tertiary hospital in patients with ACCs and correlate the immunohistochemical characteristics of ACCs with the clinical and morphological characteristics of the tumors and the survival of the patients. Forty-five patients with ACC were included in the study. All the resections were R0. The tumor size and weight, the disease stage (ENSAT classification), Weiss score and Helsinki score were examined along with immunohistochemical expression of inhibin-A, melan A, calretinin, Ki67, synaptophysin, p53, vimentin, CKAE1/AE3. The male to female ratio was 1:1.37. The median age at diagnosis was 55.5 years (IQR 19-77). The median size of ACCs was 9 cm (IQR 3.5-22 cm) and the median weight 127 g (IQR 18-1400 g). The median follow up period was 18 months (IQR 1-96). Ki67 varied from<1% to 75% (median: 16.4%). The expression of melan-A and lower expression of Ki-67 (≤4) were independently associated with longer OS time (p=0.01 and p=0.04, respectively). In multivariable analysis, tumor volume>400 cm3 (p=0.046), Weiss score>5 (p=0.007) and overexpression of p53 (p=0.036) were independent risk factors for shorter survival. Adrenocortical carcinoma is a rare and very aggressive endocrine malignancy. The most important factors that determine long-term prognosis of ACC are the disease stage at diagnosis, the Weiss score, and the Ki67 index. Immunohistochemical markers such as melan A could also serve as prognostic factors.

The role of inflammation biomarkers in differential diagnosis of pelvic tumours of ovarian origin: a single-centre observational study.

AIM OF THE STUDY: Our aim was to analyse the feasibility of white blood cell and platelet counts along with their ratios as a prognostic factor in patients who underwent surgery for ovarian mass. MATERIAL AND METHODS: We retrospectively studied the patients admitted in the Department of Gynaecology due to adnexal mass. The potential association of the neutrophil-to-lymphocyte-ratio (NLR), neutrophil-to-monocyte (NMR), platelet-to-lymphocyte (PLR), lymphocyte-to-monocyte (LMR), monocyte-to-platelet, and malignancy was evaluated. RESULTS: Patients with malignant tumours were found with significantly higher ratios of NLR (p < 0.001) and PLR (p < 0.001) and lower LMR ratio (p < 0.001) compared to those with benign tumours. Furthermore, higher lymphocyte count (p = 0.04) and platelet count (p = 0.004) were found in cancer patients when compared with borderline tumours. No significant variations were detected regarding white blood cell count (p = 0.238), NMR ratio (p = 0.28), platelet-to-neutrophil ratio (p = 0.12), and platelet-to-monocyte ratio (p = 0.34). CONCLUSIONS: Inflammation biomarker ratios can easily and inexpensive assist in distinguishing malignant ovarian tumours from benign ones.

Hypoperfusion warm ischaemia time in renal transplants from donors after circulatory death.

BACKGROUND: The donor hypoperfusion phase before asystole in renal transplants from donors after circulatory death (DCD) has been considered responsible for worse outcomes than those from donors after brain death (DBD). METHODS: We included 10 309 adult renal transplants (7128 DBD and 3181 DCD; 1 January 2010-31 December 2016) from the UK Transplant Registry. We divided DCD renal transplants into groups according to hypoperfusion warm ischaemia time (HWIT). We compared delayed graft function (DGF) rates, primary non-function (PNF) rates and graft survival among them using DBD renal transplants as a reference. RESULTS: The DGF rate was 21.7% for DBD cases, but ∼40% for DCD cases with HWIT ≤30 min (0-10 min: 42.1%, 11-20 min: 43%, 21-30 min: 38.4%) and 60% for DCD cases with HWIT >30 min (P < 0.001). All DCD groups showed higher DGF risk than DBD renal transplants in multivariable analysis {0-10 min: odds ratio [OR] 2.686 [95% confidence interval (CI) 2.352-3.068]; 11-20 min: OR 2.531 [95% CI 2.003-3.198]; 21-30 min: OR 1.764 [95% CI 1.017-3.059]; >30 min: OR 5.814 [95% CI 2.798-12.081]}. The highest risk for DGF in DCD renal transplants with HWIT >30 min was confirmed by multivariable analysis [versus DBD: OR 5.814 (95% CI 2.798-12.081) versus DCD: 0-10 min: OR 2.165 (95% CI 1.038-4.505); 11-20 min: OR 2.299 (95% CI 1.075-4.902); 21-30 min: OR 3.3 (95% CI 1.33-8.197)]. No significant differences were detected regarding PNF rates (P = 0.713) or graft survival (P = 0.757), which was confirmed by multivariable analysis. CONCLUSIONS: HWIT >30 min increases the risk for DGF greatly, but without affecting PNF or graft survival.

Biomimetic Synthesis of Oleocanthal, Oleacein, and Their Analogues Starting from Oleuropein, A Major Compound of Olive Leaves.

Oleocanthal and oleacein are known for a wide range of beneficial activities in human health and the prevention of diseases. The inability to isolate significant and pure amounts of these natural compounds and their demanding synthesis lead to the development of an efficient, five-step, three-pot procedure. The synthesis is performed by a convenient biomimetic approach, starting from oleuropein, an abundant raw material in olive leaves, through the mixed anhydride of oleoside. The method is stereocontrolled and provides an efficient approach to the synthesis of various oleocanthal analogues; thus, a small library of four compounds was prepared with 35-45% overall yield.

Synthesis, Biological Evaluation and Stability Studies of Some Novel Aza-Acridine Aminoderivatives.

Several new amino-substituted aza-acridine derivatives bearing a basic side chain have been designed and synthesized. The antiproliferative activity of the target compounds has been evaluated against three cancer cell lines-namely HCT-116 (colorectal), the uterine sarcoma MES-SA, and its doxorubicin-resistant variant MES-SA/Dx5. A limited number of the new acridines showed marginal cytotoxicity against the tested cell lines; nevertheless, these analogues possessed a similar substitution pattern. The moderate biological activity of these derivatives was attributed to their instability in aqueous media, which has been studied by mass spectrometry and computational chemistry experiments at the density functional level of theory (DFT).

Healing after Resection of Colonic Endometriosis and Growth Factor-enriched Agents: An Experimental Rat Model.

STUDY OBJECTIVE: To examine the potential beneficial effect of platelet-rich plasma (PRP) and fibrin sealant (TISSEEL; Baxter Healthcare Corporation, Deerfield, IL) on bowel wound healing after shaving of an experimentally induced endometriotic lesion. DESIGN: A single-blind, randomized study (Canadian Task Force classification I). SETTING: A certified animal research facility. ANIMALS: Thirty female Sprague-Dawley rats. INTERVENTIONS: Experimental colonic endometriosis was induced by transplanting endometrial tissue to all animals (first surgery). Thirty rats were then randomized to 1 of 3 groups according to treatment; PRP (group 1, n = 10), fibrin sealant (group 2, n = 10), or no agent (group 3, n = 10) was applied after shaving of the endometriotic nodule (second surgery). MEASUREMENTS AND MAIN RESULTS: Colonic endometriosis was successfully induced in all subjects. Four days after the second surgery, the animals were euthanized, and microscopic evaluation was performed. The pathologist was blinded to the treatment method. Histopathologic analysis revealed that compared with the control group, collagen disposition was found in a significantly higher expression in both the PRP and fibrin sealant groups (p = .011 and p = .011, respectively). Distortion of the integrity of the colon layers was statistically more pronounced in the control group compared with the fibrin sealant group (p = .033), whereas greater new blood vessel formation was observed in the fibrin sealant group compared with the control (p = .023). No histologic evidence of residual or recurrent disease was detected. CONCLUSION: Both PRP and fibrin sealant appear to be safe and associated with improved tissue healing during shaving for the excision of colonic endometriosis, attributed to the enhanced collagen disposition, neovascularization, and protection of the integrity of colon layers. Clinical trials are warranted to confirm the feasibility of PRP and fibrin sealant in the clinical setting.

Revisiting Histone Deacetylases in Human Tumorigenesis: The Paradigm of Urothelial Bladder Cancer.

Urinary bladder cancer is a common malignancy, being characterized by substantial patient mortality and management cost. Its high somatic-mutation frequency and molecular heterogeneity usually renders tumors refractory to the applied regimens. Hitherto, methotrexate-vinblastine-adriamycin-cisplatin and gemcitabine-cisplatin represent the backbone of systemic chemotherapy. However, despite the initial chemosensitivity, the majority of treated patients will eventually develop chemoresistance, which severely reduces their survival expectancy. Since chromatin regulation genes are more frequently mutated in muscle-invasive bladder cancer, as compared to other epithelial tumors, targeted therapies against chromatin aberrations in chemoresistant clones may prove beneficial for the disease. "Acetyl-chromatin" homeostasis is regulated by the opposing functions of histone acetyltransferases (HATs) and histone deacetylases (HDACs). The HDAC/SIRT (super-)family contains 18 members, which are divided in five classes, with each family member being differentially expressed in normal urinary bladder tissues. Since a strong association between irregular HDAC expression/activity and tumorigenesis has been previously demonstrated, we herein attempt to review the accumulated published evidences that implicate HDACs/SIRTs as critical regulators in urothelial bladder cancer. Moreover, the most extensively investigated HDAC inhibitors (HDACis) are also analyzed, and the respective clinical trials are also described. Interestingly, it seems that HDACis should be preferably used in drug-combination therapeutic schemes, including radiation.

A Three-Step, Gram-Scale Synthesis of Hydroxytyrosol, Hydroxytyrosol Acetate, and 3,4-Dihydroxyphenylglycol.

Hydroxytyrosol and two other polyphenols of olive tree, hydroxytyrosol acetate and 3,4-dihydroxyphenylglycol, are known for a wide range of beneficial activities in human health and prevention from diseases. The inability to isolate high, pure amounts of these natural compounds and the difficult and laborious procedures for the synthesis of them led us to describe herein an efficient, easy, cheap, and scaling up synthetic procedure, from catechol, via microwave irradiation.

Canagliflozin attenuates the progression of atherosclerosis and inflammation process in APOE knockout mice.

BACKGROUND: Sodium glucose co-transporter2 inhibitors reduce the incidence of cardiovascular events in patients with type 2 diabetes mellitus based on the results of recent cardiovascular outcome studies. Herein, we investigated the effects of long-term treatment with canagliflozin on biochemical and immunohistochemical markers related to atherosclerosis and atherosclerosis development in the aorta of apolipoprotein E knockout (Apo-E(-/-)) mice. METHODS: At the age of 5 weeks, mice were switched from normal to a high-fat diet. After 5 weeks, Apo-E(-/-) mice were divided into control-group (6 mice) treated with 0.5% hydroxypropyl methylcellulose and Cana-group (7 mice) treated with canagliflozin (10 mg/kg per day) per os. After 5 weeks of intervention, animals were sacrificed, and heart and aorta were removed. Sections stained with hematoxylin-eosin (H&E) were used for histomorphometry whereas Masson's stained tissues were used to quantify the collagen content. Immunohistochemistry to assess MCP-1, CD68, a-smooth muscle actin, MMP-2, MMP-9, TIMP-1 and TIMP-2 expression was carried out and q-PCR experiments were performed to quantify mRNA expression. RESULTS: Canagliflozin-group mice had lower total-cholesterol, triglycerides and glucose levels (P < 0.01), while heart rate was significantly lower (P < 0.05). Histomorphometry revealed that one in seven Cana-group mice versus four in six control mice developed atheromatosis, while aortic root plaque was significantly less, and collagen was 1.6 times more intense in canagliflozin-group suggesting increased plaque stability. Immunohistochemistry revealed that MCP-1 was significantly less expressed (P < 0.05) in the aortic root of canagliflozin-group while reduced expression of a-actin and CD68 was not reaching significance (P = 0.15). VCAM-1 and MCP-1 mRNA levels were lower (P = 0.02 and P = 0.07, respectively), while TIMP-1/MMP-2 ratio expression was higher in canagliflozin-group approaching statistical significance (P = 0.07). CONCLUSIONS: Canagliflozin attenuates the progression of atherosclerosis, reducing (1) hyperlipidemia and hyperglycemia, and (2) inflammatory process, by lowering the expression of inflammatory molecules such as MCP-1 and VCAM-1. Moreover, canagliflozin was found to increase the atherosclerotic plaque stability via increasing TIMP-1/MMP-2 ratio expression.
