The antiapoptotic protein BAG3 is expressed in thyroid carcinomas and modulates apoptosis mediated by tumor necrosis factor-related apoptosis-inducin…

2007

Abstract Context: We previously showed that BAG3 protein, a member of the BAG (Bcl-2-associated athanogene) co-chaperone family, modulates apoptosis in human leukemias. The expression of BAG3 in other tumor types has not been extensively investigated so far. Objective: The objective of this study was to analyze BAG3 expression in thyroid neoplastic cells and investigate its influence in cell apoptotic response to TNF-related apoptosis-inducing ligand (TRAIL). Design, Setting, and Patients: We investigated BAG3 expression in human thyroid carcinoma cell lines, including NPA, and the effect of BAG3-specific small interfering RNA on TRAIL-induced apoptosis in NPA cells. Subsequently, we analyz…

2021

Background:Golimumab showed trial efficacy in subjects with active rheumatoid arthritis (RA) previously treated with TNF-inhibitors (TNFi); no trial data are available for psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA).Objectives:To assess the effectiveness of golimumab after TNFi failure in patients with RA, PsA, or axSpA in a real-world setting.Methods:GO-BEYOND-Italy is an ongoing, multicenter, prospective, observational study of RA, PsA, or axSpA patients starting golimumab after TNFi failure. Patients were enrolled between July 2017 and December 2019, and followed for 1 year, with evaluations at 3, 6, and 12 months. This interim analysis estimates the effectiveness after…

Osteoprotegerin: multiple partners for multiple functions.

2013

Osteoprotegerin (OPG) is an essential secreted protein in bone turnover due to its role as a decoy receptor for the Receptor Activator of Nuclear Factor-kB ligand (RANKL) in the osteoclasts, thus inhibiting their differentiation. However, there are additional ligands of OPG that confer various biological functions. OPG can promote cell survival, cell proliferation and facilitates migration by binding TNF-related apoptosis inducing ligand (TRAIL), glycosaminoglycans or proteoglycans. A large number of in vitro, pre-clinical and clinical studies provide evidences of OPG involvement in vascular, bone, immune and tumor biology. This review describes an overview of the different OPG ligands regu…

Nutritional properties and plausible benefits of Pearl millet (Pennisetum glaucum) on bone metabolism and osteoimmunology : a mini-review

2020

Bone is a hard connective tissue that undergoes a systematic renewal. This highly dynamic organ is made up of four different types of cells, however, bone formation is commonly attributed to osteoblasts and bone resorption to osteoclasts. Bone tissue formation occurs during embryonic development and in certain post-birth pathological conditions. The immune system could influence the functions of bone cells, and the crosstalk between hematopoietic, immune, and bone cells is known as osteoimmunology. Indeed, cytokines produced by immune cells, including TNF-α and IL-6, are critically implicated in bone pathogenesis. It is well established that diet plays an important role in bone health and f…

TRAIL acts synergistically with iron oxide nanocluster-mediated magneto- and photothermia

2019

International audience; Targeting TRAIL (Tumor necrosis factor (TNF)-Related Apoptosis-Inducing Ligand) receptors for cancer therapy remains challenging due to tumor cell resistance and poor preparations of TRAIL or its derivatives. Herein, to optimize its therapeutic use, TRAIL was grafted onto iron oxide nanoclusters (NCs) with the aim of increasing its pro-apoptotic potential through nanoparticle-mediated magnetic hyperthermia (MHT) or photothermia (PT). Methods: The nanovector, NC@TRAIL, was characterized in terms of size, grafting efficiency, and potential for MHT and PT. The therapeutic function was assessed on a TRAIL-resistant breast cancer cell line, MDA-MB-231, wild type (WT) or T…

The appearance of several diseases, such as cancer, diabetes, high blood pressure and spread of infections mutagenic virus type can be linked to the quality and lifestyle that we lead today. Indeed, several studies on the factors triggering these so-called "morbid" long-or short-term illnesses are related to stress and quality of food consumed, whether of plant and animal origin. These diseases are becoming a common occurrence, they affect different races and all classes of society. According ethnobotanical research, naturally occurring substances, allowed civilizations to survive deadly diseases. For example, we thus find references to periods of malarial fever in China and one of the symp…

Inflammatory cytokines shape a changing DNA methylome in monocytes mirroring disease activity in rheumatoid arthritis

2019

Objective: Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease that mainly targets joints. Monocytes and macrophages are critical in RA pathogenesis and contribute to inflammatory lesions. These extremely plastic cells respond to extracellular signals which cause epigenomic changes that define their pathogenic phenotype. Here, we interrogated how DNA methylation alterations in RA monocytes are determined by extracellular signals. Methods: High-throughput DNA methylation analyses of patients with RA and controls and in vitro cytokine stimulation were used to investigate the underlying mechanisms behind DNA methylation alterations in RA as well as their relationship with clinic…

Sinergismo d'azione tra protocollo riabilitativo ed anti-TNFalfa versus terapia biologica

2012

La spondilite anchilosante è una malattia infiammatoria cronica ad eziologia sconosciuta che colpisce prevalentemente lo scheletro assile ma che può coinvolgere anche le entesi periferiche. Presso l'ambulatorio dell'U.O.C. di Riabilitazione dell'A.U.O.P. "Paolo Giaccone" di Palermo, in diciotto mesi (Aprile 2011-Maggio 2012) sono stati arruolati 24 soggetti (6 donne- 18 uomini). affetti da Spondilite Anchilosante HLA B27 diagnosticata secondo i criteri europei. Il presente studio ha mostrato efficacia nel trattamento di pazienti con SA mediante un progetto-programma riabilitativo mirato e specifico per distretto articolare. Svolgere con regolarità e costanza l'esercizio terapeutico in assoc…

Background: Registry studies broadly describing the safety of systemic drugs in psoriasis are needed. Objective: To describe the safety findings of the systemic drugs acitretin, adalimumab, apremilast, cyclosporine, etanercept, infliximab, methotrexate, secukinumab, and ustekinumab used for the treatment of moderate to severe psoriasis in patients included in the Spanish Registry of Adverse Events for Biological Therapy in Dermatological Diseases (BIOBADADERM) Registry. Methods: The incidence rate ratio (IRR) and adjusted IRR (including propensity scores) of identified adverse events for each drug, using methotrexate as reference, were determined by means of a prospective cohort.
