Insights
Signal peptide-CUB-EGF domain-containing protein 1 (SCUBE1), a novel platelet activation marker, is elevated in hypertensive patients. This finding may aid in monitoring cardiovascular events in this population.
Area of Science:
- Cardiovascular Medicine
- Biochemistry
- Hematology
Background:
- Hypertension is linked to increased platelet activation and endothelial dysfunction, raising cardiovascular event risk.
- Signal peptide-CUB-EGF domain-containing protein 1 (SCUBE1) is identified as a novel marker for platelet activation.
- Limited research exists on SCUBE1 levels in hypertensive individuals.
Purpose of the Study:
- To determine SCUBE1 levels in newly diagnosed, untreated stage 1 hypertensive patients.
- To investigate factors influencing SCUBE1 levels in hypertension.
- To explore SCUBE1 as a potential marker for cardiovascular events (CVEs).
Main Methods:
- Compared 45 hypertensive patients with 21 healthy controls.
- Measured SCUBE1, soluble CD40 ligand (sCD40L), and various biochemical markers including lipids and uric acid.
- Analyzed the relationship between SCUBE1 levels and demographic/biochemical parameters.
Main Results:
- SCUBE1 and sCD40L levels were significantly higher in hypertensive patients versus controls (P < 0.001; P < 0.05).
- Hypertensive patients exhibited higher blood pressure, uric acid, LDL, total cholesterol, and triglyceride levels.
- Systolic/diastolic BP, sCD40L, lipids, and uric acid levels correlated with SCUBE1 levels.
Conclusions:
- Elevated SCUBE1 levels are demonstrated in primary hypertensive patients.
- SCUBE1 shows potential as a novel marker for monitoring platelet activation and CVE risk in hypertension.
- Further clinical studies are recommended to validate SCUBE1's utility in cardiovascular event prediction.
Background:
Hypertension is associated with an increase in platelet activation and endothelial dysfunction and leads to a tendency to cardiovascular events (CVEs). Signal peptide-CUB-EGF domain-containing protein 1 (SCUBE1) is a novel platelet activation marker. There are currently no studies showing the level of SCUBE1 in hypertensive patients. The purpose of this study was to determine the level of SCUBE1 in this patient group and to investigate the parameters affecting that level.
Methods:
Forty-five newly diagnosed, untreated, stage 1 hypertensive patients and 21 healthy individuals were included. Blood specimens were collected to determine SCUBE1, soluble CD40 ligand, prothrombin time, partial thromboplastin time, fibrinogen, D dimer, hemogram, lipid parameters, blood urea nitrogen, creatinine, and uric acid levels. The relation between SCUBE1 level and demographic data and biochemical parameters was then investigated.
Results:
SCUBE1 and sCD40L levels obtained from plasma specimens from the hypertensive group were significantly higher than those of the control group (P < 0.001; P < 0.05, respectively). Hypertensive group blood pressure (BP) values and uric acid, low-density lipoprotein, total cholesterol, and triglyceride levels were also statistically higher than those of the control group. Parameters affecting SCUBE1 levels were systolic and diastolic BP, sCD40L, lipid parameters, and uric acid levels.
Conclusions:
We show elevated levels of SCUBE1, a novel platelet activation marker, in primary hypertensive patients. We think that, when supported by further clinical studies, this newly described marker may be useful in the monitoring of CVEs in this patient group, in which platelet activation is known to be associated with such events.
