The next step in the clinical use of microRNAs: the elimination of heparin interference

Small noncoding RNAs (miRNA) have been described as important regulators of several physiological and pathophysiological processes in cardiology. Acute coronary syndrome (ACS) leads to alterations in circulating vascular and myocardial miRNA expression profiles. miR-126-3p is one of the abundant cardiac specific miRNA with significant positive association to acute coronary syndrome. Levels of miR-126-3p in circulation are responsive to antiplatelet therapy; therefore, results of mir-126-3p measurement could be reduced in samples from these patients. Heparin is a potentially confounding factor that may influence miRNA measurements in patients with acute cardiovascular disease because antiplatelet therapy (administrations of intravenous heparin) increases its endogenous levels. Interaction between heparin and antithrombin III in vivo cause improvement of the anticoagulant effect. It is a well-known fact that commonly used qPCR methods for miRNA detection do not recommend heparinised samples for testing due to its interference with enzymatic reaction. However, the heparin effect on endogenous mirRNAs cannot be fully explained by interference with DNA polymerases or magnesium ions. The reason could be based on heparin’s ability to disrupt already formed enzyme-template complexes with sequence-dependent displacement or miRNAs compartmentalization. Several different methods to minimize the effect of heparin on qPCR reactions were described. It seems to be beneficial to use heparinase treatment as an additional step in the sample preparation procedure because it is difficult to adjust the heparin interference threshold of cardiology patients unlike the physiological range of healthy individuals (0.10 – 0.24 IU/mL). The type of collection tube also contributes to external influence of miRNA measurement. Similar to heparin, other commonly used anticoagulants have been shown to interfere with RT-qPCR miRNAs measurement, with EDTA plasma yielding the best miRNAs profiles compared to others sample types. In our pilot study we demonstrate the effect of endogenous and exogenous heparin interference to miR-126-3p quantification in two methods – RT-qPCR and enzyme immunoassay for miRNA quantification (miREIA). The difference between methods is that miREIA does not require reverse transcription which is a critical step for heparin interference.

Increased occurrence of Treponema spp. and double-species infections in patients with Alzheimer's disease

Although the link between microbial infections and Alzheimer's disease (AD) has been demonstrated in multiple studies, the involvement of pathogens in the development of AD remains unclear. Here, we investigated the frequency of the 10 most commonly cited viral (HSV-1, EBV, HHV-6, HHV-7, and CMV) and bacterial (Chlamydia pneumoniae, Helicobacter pylori, Borrelia burgdorferi, Porphyromonas gingivalis, and Treponema spp.) pathogens in serum, cerebrospinal fluid (CSF) and brain tissues of AD patients. We have used an in-house multiplex PCR kit for simultaneous detection of five bacterial and five viral pathogens in serum and CSF samples from 50 AD patients and 53 healthy controls (CTRL). We observed a significantly higher frequency rate of AD patients who tested positive for Treponema spp. compared to controls (AD: 62.2 %; CTRL: 30.3 %; p-value = 0.007). Furthermore, we confirmed a significantly higher occurrence of cases with two or more simultaneous infections in AD patients compared to controls (AD: 24 %; CTRL 7.5 %; p-value = 0.029). The studied pathogens were detected with comparable frequency in serum and CSF. In contrast, Borrelia burgdorferi, human herpesvirus 7, and human cytomegalovirus were not detected in any of the studied samples. This study provides further evidence of the association between microbial infections and AD and shows that paralleled analysis of multiple sample specimens provides complementary information and is advisable for future studies.

Specific microRNAs and heart failure: time for the next step toward application?

A number of microRNAs are involved in the pathophysiological events associated with heart disease. In this review, we discuss miR-21, miR-1, miR-23a, miR-142-5p, miR-126, miR-29, miR-195, and miR-499 because they are most often mentioned as important specific indicators of myocardial hypertrophy and fibrosis leading to heart failure. The clinical use of microRNAs as biomarkers and for therapeutic interventions in cardiovascular diseases appears highly promising. However, there remain many unresolved details regarding their specific actions in distinct pathological phenomena. The introduction of microRNAs into routine practice, as part of the cardiovascular examination panel, will require additional clinically relevant and reliable data. Thus, there remains a need for additional research in this area, as well as the optimization and standardization of laboratory procedures which could significantly shorten the determination time, and make microRNA analysis simpler and more affordable. In this review, we aim to summarize the current knowledge about selected microRNAs related to heart failure, including their potential use in diagnosis, prognosis, and treatment, and options for their laboratory determination.

Dynamic release of neuronal extracellular vesicles containing miR-21a-5p is induced by hypoxia

Hypoxia induces changes in the secretion of extracellular vesicles (EVs) in several non-neuronal cells and pathological conditions. EVs are packed with biomolecules, such as microRNA(miR)-21-5p, which respond to hypoxia. However, the true EV association of miR-21-5p, and its functional or biomarker relevance, are inadequately characterised. Neurons are extremely sensitive cells, and it is not known whether the secretion of neuronal EVs and miR-21-5p are altered upon hypoxia. Here, we characterised the temporal EV secretion profile and cell viability of neurons under hypoxia. Hypoxia induced a rapid increase of miR-21a-5p secretion in the EVs, which preceded the elevation of hypoxia-induced tissue or cellular miR-21a-5p. Prolonged hypoxia induced cell death and the release of morphologically distinct EVs. The EVs protected miR-21a-5p from enzymatic degradation but a remarkable fraction of miR-21a-5p remained fragile and non-EV associated. The increase in miR-21a-5p secretion may have biomarker potential, as high blood levels of miR-21-5p in stroke patients were associated with significant disability at hospital discharge. Our data provides an understanding of the dynamic regulation of EV secretion from neurons under hypoxia and provides a candidate for the prediction of recovery from ischemic stroke.

Deep Amplicon Sequencing of POLE Gene for Effective Endometrial Tumour Diagnostics Using fastGEN Technology.

Tumor DNA testing of POLE gene, which is component of DNA polymerase epsilon, is a prerequisite for tumor risk-group assessment and personalized treatment in endometrial carcinoma. POLE mutated tumors are low risk and adjuvant chemotherapy should be deescalated. POLE mutations occur in 7 - 12% of endometrial cancers and have been associated with high tumor mutation burden, neoantigen load. Retrospective analysis showed that pathogenic POLE mutations are associated with clinical benefit to immune checkpoint inhibitor therapy, thus further thorough studies are warranted to validate POLE mutation as a predictive biomarker. Deep amplicon next-generation sequencing (NGS) has a potential to be a suitable method for simultaneous direct detection of all somatic mutation within tested regions. Aim of the study was to develop and verify a fast NGS library preparation of tumor DNA samples for the detection of mutations in clinically relevant codons of POLE gene.

Acute Viral and Bacterial Infection Differentiation: Comparison of Novel Analytical Methods of Myxovirus Resistance Protein A (MxA) Quantitative Determination

The early distinction between viral and bacterial infections in patients is difficult based on clinical or routinely available biological findings only. Due to this fact, patients are often unnecessarily treated with antibiotics, which results in the emergence of antibiotics resistance. Myxovirus resistance protein A (MxA) is mentioned in number of studies as an important antiviral factor that inhibits the multiplication of RNA and DNA viruses. It is an intracellular protein produced by cells of the immune system after stimulation by type I and III interferons in response to a viral infection. Rhedin et al. used MxA to differentiate between bacterial and viral infection in children with lower respiratory tract infection. The highest MxA values were achieved in samples positive for influenza and respiratory syncytial virus. A study by Toivonen et al. demonstrated that some types of viral respiratory disease agents (respiratory syncytial virus, influenza A and B viruses, parainfluenza virus, etc.) induced significantly higher levels of MxA than others (rhinovirus, coronaviruses).
