TERTmonitor Efficacy and Performance in Detecting Mutations by Droplet Digital PCR.

Background: The screening of TERT promoter () mutations is essential in cancer research and diagnostics, due to its prevalence in tumours associated with low self-renewal rates. TERTmonitor is a diagnosis kit primarily designed for real-time qPCR qualitative detection of -124C>T and -146C>T mutations, which are highly prevalent in several malignancies, particularly in bladder carcinoma.

Objective: This study aims to investigate TERTmonitor performance in droplet digital PCR (ddPCR) in urine samples from bladder cancer patients.

TERTmonitor-qPCR Detection of Mutations in Glioma.

Telomerase promoter (TERTp) mutations are frequently observed in various types of tumours and commonly characterised by two specific hotspots located at positions -124 and -146 upstream of the start codon. They enhance activity, resulting in increased TERT expression. In central nervous system (CNS) tumours, they are integrated as biomarkers, aiding in the diagnosis and with a role in prognosis, where, in some settings, they are associated with aggressive behaviour.

Combining inflammatory miRNA molecules as diagnostic biomarkers for depression: a clinical study.

Background: Inflammation has been implicated in core features of depression pathophysiology and treatment resistance. Therefore, new challenges in the discovery of inflammatory mediators implicated in depression have emerged. MicroRNAs (miRNAs) have been found aberrantly expressed in several pathologies, increasing their potential as biomarkers and therapeutical targets.

Stress-induced depressive-like behavior in male rats is associated with microglial activation and inflammation dysregulation in the hippocampus in adulthood.

Neuroinflammation is increasingly recognized as playing a critical role in depression. Early-life stress exposure and constitutive differences in glucocorticoid responsiveness to stressors are two key risk factors for depression, but their impacts on the inflammatory status of the brain is still uncertain. Moreover, there is a need to identify specific molecules involved in these processes with the potential to be used as alternative therapeutic targets in inflammation-related depression.

TNF-alpha-induced microglia activation requires miR-342: impact on NF-kB signaling and neurotoxicity.

Growing evidences suggest that sustained neuroinflammation, caused by microglia overactivation, is implicated in the development and aggravation of several neurological and psychiatric disorders. In some pathological conditions, microglia produce increased levels of cytotoxic and inflammatory mediators, such as tumor necrosis factor alpha (TNF-α), which can reactivate microglia in a positive feedback mechanism. However, specific molecular mediators that can be effectively targeted to control TNF-α-mediated microglia overactivation, are yet to be uncovered.

miR-99a in bone homeostasis: Regulating osteogenic lineage commitment and osteoclast differentiation.

Background: The tight coupling between osteoblasts and osteoclasts is essential to maintain bone homeostasis. Deregulation of this process leads to loss and deterioration of the bone tissue causing diseases, such as osteoporosis. MicroRNAs are able to control bone-related mechanisms and have been explored as therapeutic tools.

miR-195 inhibits macrophages pro-inflammatory profile and impacts the crosstalk with smooth muscle cells.

Macrophages are a main component of atherosclerotic plaques. Recent studies suggest that pro-inflammatory M1 macrophages are pro-atherogenic while M2 macrophages promote plaque stability. Moreover, toll-like receptor signalling pathways are implicated in atherosclerotic plaque formation, evolution and regression.
