Andrea Angeletti, Paolo Cravedi
Immunosuppression in kidney transplantation is still largely driven by center-specific protocols and adjusted according to the presence of graft dysfunction, drug toxicity or infection. Due to the current inability to titrate immunosuppression to the needs of every single patient, this approach is burdened by an increased risk of under or over-immunosuppression. To extend allograft survival, immunosuppression should be decided based on reliable biomarkers capable of quantifying the alloimmune response and/or noninvasively diagnosing acute rejection...

Ovarian hyperstimulation syndrome (OHSS) is a potentially life‑threatening, iatrogenic complication that occurs during assisted reproduction. Polycystic ovarian syndrome (PCOS) significantly increases the risk of OHSS during controlled ovarian stimulation. Therefore, a more effective early prediction technique is required in PCOS patients. Quantitative proteomic analysis of serum proteins indicates the potential diagnostic value for disease. In the present study, the authors revealed the differentially expressed proteins in OHSS patients with PCOS as new diagnostic biomarkers...

MicroRNAs are short non-coding RNAs that play important roles in gliomas. However, the role of miR-130b in glioma remains unclear. In the present study, miR-130b expression was upregulated in glioma tissues and cell lines. Kaplan-Meier analysis indicated that the upregulation of miR-130b expression correlated with poor prognoses in glioma patients. Multivariate analysis demonstrated that this upregulation and a high-grade classification were independent factors that both predicted poor outcomes for glioma patients...

Previous studies have suggested that dysregulation of microRNA (miR) -124a is associated with various types of human cancer. However, there are few studies reporting the level of miR‑124a expression in non‑small cell lung cancer (NSCLC). The present study investigated the association between miR‑124a and NSCLC by analyzing the differential expression of miR‑124a in NSCLC using the GEO database, as well as subsequently performing reverse transcription‑quantitative polymerase chain reaction analysis on 160 NSCLC biopsies, 32 of which were paired with adjacent normal tissues...

PURPOSE: Gliomas are the most common primary intracranial tumors of the central nervous system (CNS), accounting for about one third of all brain tumors. Glioblastoma multiforme (GBM) is the aggressive grade IV glioma with survival as low as 2-5% in the second year post-diagnosis, hence necessitating efficient diagnostic markers. More than 50% of the non-small cell lung cancer (NSCLC) brain metastases are solitary lesions, often difficult to differentiate from gliomas by conventional imaging diagnostics...

Renal dysfunction is a common complication of liver cirrhosis and of utmost clinical and prognostic relevance. Patients with cirrhosis are more prone to developing acute kidney injury (AKI) than the non-cirrhotic population. Pre-renal AKI, the hepatorenal syndrome type of AKI (HRS-AKI, formerly known as 'type 1') and acute tubular necrosis represent the most common causes of AKI in cirrhosis. Correct differentiation is imperative, as treatment differs substantially. While pre-renal AKI usually responds well to plasma volume expansion, HRS-AKI and ATN require different specific approaches and are associated with substantial mortality...

Bladder cancer (urothelial cancer of the bladder) is the most common malignancy affecting the urinary system with increasing incidence and mortality. Treatment of bladder cancer has not advanced in the past 30 years. Therefore, there is a crucial unmet need for novel therapies, especially for high grade/stage disease that can only be achieved by preclinical model systems that faithfully recapitulate the human disease. Animal models are essential elements in bladder cancer research to comprehensively study the multistep cascades of carcinogenesis, progression and metastasis...

High-throughput sequencing (HTS) of the T-cell receptor (TCR) is a rapidly advancing technique that allows sensitive and accurate identification and quantification of every distinct T-cell clone present within any biological sample. The relative frequency of each individual clone within the full T-cell repertoire can also be studied. HTS is essential to expand our knowledge on the diversity of the TCR repertoire in homeostasis or under pathologic conditions, as well as to understand the kinetics of antigen-specific T-cell responses that lead to protective immunity (i...

Anxiety is a psychological problem that often emerges during the normal course of human life. The detection of anxiety often involves a physical exam and a self-reporting questionnaire. However, these approaches have limitations, as the data might lack reliability and consistency upon application to the same population over time. Furthermore, there might be varying understanding and interpretations of the particular question by the participant, which necessitating the approach of using biomarker-based measurement for stress diagnosis...

BACKGROUND: About half of patients with major depressive disorder (MDD) have clinically meaningful levels of anxiety. Greater severity of depressive illness and functional impairment has been reported in patients with high levels of anxiety accompanying depression. The pathogenesis for the comorbidity was still unsure. AIM: This study aimed to determine whether there would be molecular link for overlapped pathogenesis between MDD and anxiety disorder. MATERIALS AND METHODS: Using long noncoding RNA (lncRNA) microarray profiling and reverse transcription polymerase chain reaction, six downregulated lncRNAs and three upregulated lncRNAs had been identified to be the potential biomarkers for MDD and generalized anxiety disorder (GAD), respectively...

Adult-onset Still's disease (AOSD) is a rare systemic auto-inflammatory disorder (SAID). Although the pathogenesis of the disease is complex and far from being fully understood, recent progresses in pathophysiological knowledge have paved the way to new diagnostic approaches. Indeed, AOSD diagnosis can be a real challenge, owing to its infrequency, and to the lack of specificity of the principal clinical features (high fever, arthralgia or arthritis, skin rash) and laboratory findings (elevated acute phase reactants, hyperleukocytosis ≥ 10,000 cells/mm(3) with neutrophils ≥80%)...

Determination of the role of insulin-like growth factor (IGF) family components in carcinogenesis of several human tumors is based on numerous epidemiological and pre-clinical studies, experiments in vivo and in vitro and on attempts at application of drugs affecting the IGF axis. Investigative hypotheses in original studies were based on biological functions manifested by the entire family of IGF (ligands, receptors, linking proteins, adaptor molecules). In the context of carcinogenesis the most important functions of IGF family involve intensification of proliferation and inhibition of cell apoptosis and effect on cell transformation through synthesis of several regulatory proteins...

Bipolar disorder (BD) is a recurrent, episodic mood disorder for which there are no current diagnostic, prognostic or theranostic biomarkers. Two peripheral markers of the acute phase immune response, zinc and neopterin, are consistently associated with severity of depression in literature. Given gender differences in clinical presentation of BD and in inflammatory processes, we aimed to explore the interaction between gender and immune biomarkers to predict mood severity in BD. Participants with DSM IV BD I and II were recruited through the Pennsylvania Psychiatric Institute during an acute mood episode...

Cholangiocarcinoma (CCA) is a deadly disease that poorly responds to chemotherapy and radiotherapy and whose incidence has increased worldwide. Furthermore, long noncoding RNAs (lncRNAs) play important roles in multiple biological processes, including tumorigenesis. Specifically, H19, the first discovered lncRNA, has been reported to be overexpressed in diverse human carcinomas, but the overall biological role and clinical significance of H19 in CCA remains unknown. In the present study, expression levels of H19 were investigated in CCA tissues and cell lines and were correlated with clinicopathological features...
