Introduction

Adapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways. Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif. Binding generally results in the modulation of the activity of the binding partner. Negatively regulates the kinase activity of PDPK1.

AbstractObjectivesEarly rheumatoid arthritis (RA) detection is crucial for improving patient prognosis. Anticyclic citrullinated peptide antibodies (anti-CCP) and rheumatoid factors (RF) support RA diagnosis but are undetectable in ∼20 % of cases. Recently, antibodies against mutated citrullinated vimentin (anti-MCV) and detection of 14-3-3 eta have emerged with implications for preclinical RA diagnosis and monitoring treatment. The objective of this study was to assess the clinical performance of anti-MCV antibodies and 14-3-3 eta in RA and to compare it to current RA criteria anti-CCP and RF markers, individually and in combination.MethodsA retrospective chart review of 326 subjects submitted for RA serology testing identified 134 RA positive and 192 RA negative disease control individuals. Fifty healthy controls specimens were also included. Performance of anti-MCV and 14-3-3 eta, alone and combined with CCP3.1 and RF, was assessed.ResultsAnti-MCV had a sensitivity of 71 % and a specificity of 92 %. 14-3-3 eta had a sensitivity of 43 % and a specificity of 90 %. In comparison, CCP3.1 and RF displayed a sensitivity of 79 % and 84 % and a specificity of 92 % and 61 %, respectively. ROC curve analysis demonstrated CCP3.1 and anti-MCV had superior diagnostic performance compared to RF and 14-3-3 eta. In our cohort, anti-MCV and 14-3-3 eta failed to identify seronegative RA patients. Different combinations of double antibody positivity increased specificity at the cost of lost sensitivity.ConclusionsIndividually, 14-3-3 eta, anti-MCV and CCP3.1 assays had ≥90 % specificity in diagnosed RA patients, with better sensitivities for anti-MCV and CCP3.1 than 14-3-3 eta. Overall diagnostic performance of anti-MCV was similar to CCP3.1 and RF, all of which outperformed 14-3-3 eta in our cohort.

Integrating Forensic Autopsies with Proteomic Profiling for Suicide Risk Assessment: A Comprehensive Review of Literature

Article

Author: Al-Habash, Ibrahim H. ; Radaelli, Davide ; Keckarevic-Markovic, Milica ; Concato, Monica ; Alshaeb, Asma Mahmoud ; Srpanova, Viktorija Belakaposka ; Alempijevic, Djordje ; D’Errico, Stefano

Background:Suicide is a major global public health concern that affects people of all ages, with over 700000 individuals intentionally ending their lives every year. Suicide is a multifactorial event related to multiple risk factors interlocking with each other, among which neurobiological factors are considered to be an objective measure of the incidence of this phenomenon and can be used as a measurable tool for evaluating suicidal tendencies.Objective:The aim of this study is to thoroughly examine available data and assess candidate proteins as prospective biomarkers for predicting suicides and ascertaining the manner of death in forensic cases.Methods:An electronic search was conducted on PubMed, Science Direct Scopus, and the Excerpta Medica Database. The systematic review adhered to PRISMA guidelines and encompassed case series, prospective and retrospective studies, and short communications published in English. The focus was on proteomics and suicide, specifically, those studies where researchers conducted human proteomic analyses on specimens obtained from individuals who completed or attempted suicide.Results:A total of 14 studies met the inclusion criteria, resulting in a dataset of numerous candidate protein biomarkers. These include tenascin-C, potassium voltage-gated channel subfamily Q member 3, vimentin-immunoreactive astrocytes, glutathione S-transferase theta 1, iron transport proteins, Acrystallin chain B, manganese superoxide dismutase, glial fibrillary acidic protein, various glycolytic pathway proteins, 14-3-3 eta and 14-3-3 theta proteins, specific cytoskeleton proteins, C-reactive protein, serum amyloid A protein 1, extrinsic coagulation pathway proteins, the vacuolar-type proton pump ATPase subunit, plasma apolipoprotein A-IV, and ER stress proteins. These proteins are proposed as a panel of biomarkers to be evaluated in conjunction with other clinical predictors of suicide.Conclusion:This review aims to provide a comprehensive summary of all proteomic studies conducted on cases of attempted or completed suicide. By doing so, it seeks to bridge existing gaps in knowledge and pave the way for future investigations. The ultimate goal is to potentially identify a suicide biomarker.

14-3-3 Eta protein as a novel biomarker in early detection of uveitis in Egyptian juvenile idiopathic arthritis and rheumatoid arthritis patients: Diagnostic and prognostic value

Article

Author: Al Sharaki, Dina Rifaat ; Saif, Dalia Salah ; Fotoh, Dina Salem ; Dawoud, Manar Fawzy ; Medhat, Abeer

AbstractBackground and ObjectivesJuvenile Idiopathic Arthritis (JIA) and Rheumatoid arthritis (RA) are autoimmune chronic inflammatory disorders of undetermined cause. Uveitis is one of the commonest and most dangerous extra-articular manifestations of JIA and RA presenting chronic anterior uveitis with non-specific biomarkers for its early detection. We evaluated the role of serum 14-3-3 Eta protein to assess its potential role as a novel biomarker for the early detection of uveitis in Egyptian JIA and RA patients as well as its correlation with disease activity.MethodsA case-control study included three patient groups: group I includes 42 JIA patients, group II includes 42 RA patients, and an equal number of apparently healthy individuals matched in sex and age for each group of patients as controls, recruited from the rheumatology outpatient clinic. All participants were subjected to clinical examination, laboratory investigations with assessment of serum levels of 14-3-3 Eta protein, and ophthalmologic investigations to assess disease activity, eye affection, and its relation to 14-3-3 Eta protein level, and other disease variables among those patients.Resultsa statistically significant difference was estimated between the two patients’ groups and controls regarding 14-3-3 Eta protein level. 14-3-3 Eta protein has a significant positive correlation with disease activity in JIA and RA patients. Also, RA patients with clinical uveitis had higher levels of the 14-3-3 Eta protein, while there were no significant differences among JIA patients with or without uveitis.Conclusion14-3-3 Eta protein is a potential diagnostic biomarker in early detection of uveitis in RA patients, as it is higher in patients versus controls especially those with uveitis with a cut-off point 57.5, at which patients must have a thorough eye examination to receive early intervention and, to prevent complications, while it doesn’t have the same role in JIA patients. 14-3-3 Eta protein is a potential diagnostic and prognostic marker for JIA and RA being correlated with disease activity.
