Abstract
PURPOSE Acromegaly is closely related to increased oxidative stress and endothelial dysfunction (ED). This study aimed to evaluate, for the first time in the literature, signal peptide-CUB-EGF domain-containing protein 1 (SCUBE-1) and endothelial nitric oxide synthase e(NOS) levels in the setting of acromegaly. METHOD A total of 56 acromegaly patients and a control group composed of 30 healthy volunteers were included in this study. In the postoperative follow-up, patients were grouped as active or in-remission according to their GH and IGF-1 levels in oral glucose stimulation test (OGST). After detailed physical examination of acromegaly patients and the control subjects, 8-hour fasting blood samples were collected to evaluate biochemical parameters including lipid profile, anterior pituitary hormones, and SCUBE-1 and e(NOS) levels. RESULTS Inactive and active acromegaly was noted in 78.6% and 21.4% of patients, respectively. The median (min-max) SCUBE-1 levels were significantly higher in the inactive acromegaly and active acromegaly groups than in the control group (1.6(0.4-2.4) and 1.8(1.1-2.5) vs. 0.4(0.2-1.0) ng/mL, respectively, p < 0.001 for each). The median (min-max) e(NOS) levels were significantly higher in the inactive acromegaly and active acromegaly groups than in the control group (132.7 (26.8-602.9) and 137.3 (69.7-488.7) vs. 83.9 (16.4-218.7) pg/mL, p = 0.018 and p = 0.048, respectively). We have also detected positive correlations of e(NOS) with leukocyte (r = 0.307, p = 0.021) and neutrophil counts (r = 0.309, p = 0.021). CONCLUSION Our study revealed for the first time in literature that SCUBE-1 levels, being a novel marker for ED, were significantly higher in acromegaly patients than in control subjects. When supported with clinical studies, SCUBE-1can be used as an early indicator of endothelial damage in acromegaly patients.

Could SCUBE-1 be a marker for subclinical atherosclerosis other than carotid artery intima-media thickness in patients with psoriasis? An Bras Dermatol 2023; 98:595-601. [PMID: 37198010 PMCID: PMC10404550 DOI: 10.1016/j.abd.2022.08.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 08/10/2022] [Accepted: 08/12/2022] [Indexed: 05/19/2023] Open
Abstract
BACKGROUND Psoriasis is a chronic inflammatory disease that is associated with many inflammatory conditions such as atherosclerosis, hypertension, among others. SCUBE-1 is a protein that plays a role in angiogenesis. OBJECTIVES The present study aimed to investigate whether SCUBE-1 could indicate subclinical atherosclerosis in psoriatic patients, and to compare SCUBE-1 levels, measurement of carotid artery ıntima-media thickness (CIMT), and metabolic parameters in psoriasis patients and healthy controls. METHODS Forty-six patients with psoriasis and 43 healthy controls were included. The severity of the disease was assessed with Psoriasis Area Severity Index (PASI) in the patient group. Levels of SCUBE-1, CRP, lipids, and fasting glucose were measured with the enzyme-linked ımmunosorbent assay (ELISA) method, and CIMT measurements were performed by the same cardiologist. RESULTS SCUBE-1 levels and CIMT values were significantly higher in the patient group (for both p < 0.05). Moreover, systolic blood pressure, CRP levels, and waist circumference were higher in the patient group even though both groups had similar BMIs (for all p < 0.05). A positive correlation was found between SCUBE-1 and CIMT values among patients, and multiple regression analyses revealed that SCUBE-1 and CIMT are significantly associated with psoriasis as well. STUDY LIMITATIONS A low number of participants and not including any other inflammatory marker related to angiogenesis or atherosclerosis such as VEGF, adiponectin are the main limitations of the present study. CONCLUSION Despite the severity of the disease, even in psoriasis patients with mild disease the SCUBE-1 level may be an indicator of subclinical atherosclerosis and indicate the risk of cardiovascular disease in the future.

Abstract
OBJECTIVE To examine the SCUBE1 level, a biomarker in vascular biology that could determine the prognosis of cardiovascular events during OSA treatment. METHODS In total, 129 patients were included in the study. Thirty were diagnosed with simple snoring and 99 with OSA. RESULTS In males, significant correlation was determined between SCUBE1 non-REM AHI, hypopnea index, total apnea index, mean SO2, minimum SO2, and < 90% saturation duration. CONCLUSION Serum SCUBE1 levels increased more in male patients with severe OSA compared to other OSA levels, and high serum SCUBE1 levels were found to be associated with lower oxygen levels in OSA patients. The SCUBE1 biomarker can correlate with severe OSA in males. There was a statistically significant difference between OSA groups in terms of SCUBE1 score for male patients (p = 0.002) but not for females (p = 0.498). It is important that future SCUBE1 studies evaluate males vs. females.

Discovering the Protective Effects of Resveratrol on Aflatoxin B1-Induced Toxicity: A Whole Transcriptomic Study in a Bovine Hepatocyte Cell Line. Antioxidants (Basel) 2021; 10:antiox10081225. [PMID: 34439473 PMCID: PMC8388899 DOI: 10.3390/antiox10081225] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 07/26/2021] [Accepted: 07/27/2021] [Indexed: 12/13/2022] Open
Abstract
Aflatoxin B1 (AFB1) is a natural feed and food contaminant classified as a group I carcinogen for humans. In the dairy industry, AFB1 and its derivative, AFM1, are of concern for the related economic losses and their possible presence in milk and dairy food products. Among its toxic effects, AFB1 can cause oxidative stress. Thus, dietary supplementation with natural antioxidants has been considered among the strategies to mitigate AFB1 presence and its toxicity. Here, the protective role of resveratrol (R) has been investigated in a foetal bovine hepatocyte cell line (BFH12) exposed to AFB1, by measuring cytotoxicity, transcriptional changes (RNA sequencing), and targeted post-transcriptional modifications (lipid peroxidation, NQO1 and CYP3A enzymatic activity). Resveratrol reversed the AFB1-dependent cytotoxicity. As for gene expression, when administered alone, R induced neglectable changes in BFH12 cells. Conversely, when comparing AFB1-exposed cells with those co-incubated with R+AFB1, greater transcriptional variations were observed (i.e., 840 DEGs). Functional analyses revealed that several significant genes were involved in lipid biosynthesis, response to external stimulus, drug metabolism, and inflammatory response. As for NQO1 and CYP3A activities and lipid peroxidation, R significantly reverted variations induced by AFB1, mostly corroborating and/or completing transcriptional data. Outcomes of the present study provide new knowledge about key molecular mechanisms involved in R antioxidant-mediated protection against AFB1 toxicity.

Abstract
PURPOSE Signal peptide-CUB-Epidermal growth factor-like domain-containing protein 1 (SCUBE-1) is a protein expressed on the cell surface of endothelial cells and platelets. We aimed to determine the alterations in SCUBE-1 levels in patients at different stages of diabetic retinopathy (DR). MATERIALS AND METHODS Participants were grouped into 4 regarding the presence and stage of diabetic retinopathy as follows: control group (n 32), patients without DR (n 39), patients with background DR (n 42) and patients with proliferative DR (n 55). Age, gender, duration of diabetes, fasting blood glucose levels, serum hemoglobin A1c (HbA1c), SCUBE-1 and malondialdehyde (MDA) levels of the patients were recorded. Central macular thickness and central macular volume were recorded and compared between groups. RESULTS Totally 136 patients with diabetes mellitus and 32 control cases were included in the study. There is a significant increase in SCUBE-1 and MDA levels with an advance in DR. In correlation analysis, there was only a significant correlation present between serum SCUBE-1 and MDA levels (p 0.001) but not with other parameters. CONCLUSION For the first time in literature, we determined a significant increase in SCUBE-1 levels in patients with DR. Moreover, with an advance in DR, SCUBE-1 levels were also increasing.
