William L Hwang, Katie L Hwang, David T Miyamoto
The rapidly growing array of therapeutic options in cancer requires informative biomarkers to guide the rational selection and precision application of appropriate therapies. Circulating biomarkers such as circulating tumor cells have immense potential as noninvasive, serial 'liquid biopsies' that may be more representative of the complete spectrum of a patient's individual malignancy than spatially and temporally restricted tumor biopsies. In this review, we discuss the current state-of-the-art in the isolation and molecular characterization of circulating tumor cells as well as their utility in a wide range of clinical applications such as prognostics, treatment monitoring and identification of novel therapeutic targets and resistance mechanisms to enable real-time adjustments in the clinical management of cancer...

AIM: Glaucoma is a multifactorial disease of retinal ganglion cells, with low prognosis. For that reason, the identification of biomarkers in peripheral blood samples for diagnostics and treatment of the disease is needed. To establish mRNA expression level of several oxidative stress biomarkers reported in aqueous humor of patients with primary open-angle glaucoma (POAG). MATERIALS & METHODS: The mRNA expression levels of eight genes from 15 patients diagnosed with POAG and 11 control subjects were analyzed using an RT(2) Custom Profiler PCR Array...

AIM: To investigate the role of gelsolin-like actin-capping protein (CapG) in prostate cancer (PCa). MATERIALS & METHODS: CapG expression and its correlation with clinicopathological characters and patient prognosis were analyzed in 76 cases of PCa by immunohistochemistry and qRT-PCR. Then, the influence of CapG downregulation on cell apoptosis and proliferation were assessed. RESULTS: CapG expression in PCa was significantly higher compared with those in matched adjacent noncancerous prostate tissues, and significantly correlated with clinicopathological characters...

AIM: To evaluate serum growth arrest-specific gene 6 (Gas6) concentration as a biomarker of liver fibrosis progression. MATERIALS & METHODS: One hundred and thirteen consecutive patients affected by chronic liver disease underwent transient elastography, Gas6 measurement and, if clinically indicated, liver biopsy. RESULTS: Gas6 concentration was directly correlated to liver stiffness (r = 0.67; p < 0.0001) and was significantly higher in patients with advanced fibrosis (Ishak 4-5; p < 0...

Pieranna Chiarella, Giovanna Tranfo, Daniela Pigini, Damiano Carbonari
The European classification, labeling and packaging classified formaldehyde as human carcinogen Group 1B and mutagen 2, fostering the re-evaluation of the exposure risk in occupational settings. Although formaldehyde exposure is traditionally measured in air, many efforts were made to identify specific exposure biomarkers: urinary formaldehyde, formic acid and DNA damage indicators. Though used in combination, none of these seems satisfactory. The influence of the metabolism on exogenous formaldehyde levels, the exposure to other xenobiotics, the difference in genetic background and metabolism efficiency, misled the relationship between genotoxicity and exposure data...

AIM: Coronary collateral circulation (CCC) has an important impact on cardiovascular prognosis and well-developed CCC is associated with better clinical outcomes. We investigated whether lymphocyte/monocyte ratio (LMR) has an association with CCC in patients with stable coronary artery disease (SCAD). METHODS: The study population consisted of 245 patients with SCAD. Patients were classified into a poor CCC group (Rentrop grades 0/1, n = 87), or good CCC group (Rentrop grades 2/3, n = 158)...

miRNAs are key regulators of gene expression, and alterations in their expression levels correlate with the onset and progression of cancer. Although miRNAs have been proposed as biomarkers for cancer diagnosis, their application in routine clinical praxis is yet to come. Current quantification strategies have limitation, and there is a great interest in developing innovative ones. Since a few years, nanotechnology-based approaches for miRNA quantification are emerging at fast pace but there is urgent need to go beyond the proof-of-concept stage...

AIM: Sepsis is a critical condition that leads to high mortality and is the most common cause of death in intensive care units. Despite exhaustive efforts by the scientific community, a reliable biomarker for diagnosis, evolution and prognosis of sepsis is still lacking. Results/methodology: Here, using high-throughput proteomics, we describe N-acetylmuramoyl-l-alanine amidase as a novel candidate for differentiating infectious and noninfectious inflammatory syndromes. DISCUSSION/CONCLUSION: This is the first description of N-acetylmuramoyl-l-alanine amidase as a biomarker that can be used alone or in conjunction with other biomarkers to facilitate the diagnosis of sepsis in the critically ill...

AIM: Inflammation plays an important role in development of coronary collateral circulation (CCC). The aim of this study is to determine whether the inflammation-related miRNA miR-155 and the inflammation marker VCAM-1 could be a biomarker for CCC. PATIENTS & METHODS: We measured levels of plasma VCAM-1 and miR-155 in patients with CCC according to Rentrop grade by ELISA or real-time polymerase chain reaction, respectively (n = 112). RESULTS: Plasma miR-155 was negatively correlated with VCAM-1 in the poor CCC group and with Rentrop grade in all patients with CCC...

Andrew J Krentz, Marcus Hompesch
The clinical utility of diabetes biomarkers can be considered in terms of diagnosis, management and prediction of long-term vascular complications. Glucose satisfies all of these requirements. Thresholds of hyperglycemia diagnostic of diabetes reflect inflections that confer a risk of developing long-term microvascular complications. Degrees of hyperglycemia (impaired fasting glucose, impaired glucose tolerance) that lie below the diagnostic threshold for diabetes identify individuals at risk of progression to diabetes and/or development of atherothrombotic cardiovascular disease...
