INTRODUCTION Rheumatoid arthritis (RA) is a T-cell-mediated systemic autoimmune disease, characterized by synovium inflammation and articular destruction. Bone marrow mesenchymal stem cells (MSCs) could be effective in the treatment of several autoimmune diseases. However, there has been thus far no report on umbilical cord (UC)-MSCs in the treatment of RA.(More)
OBJECTIVE Several studies have reported STAT4 polymorphism is strongly associated with increased susceptibility to rheumatoid arthritis (RA). However, a study from China showed no association between STAT4 and RA susceptibility in a Chinese Han subpopulation. Since the northern Hans are known to be genetically different from the southern Hans, the aim of(More)
Phosphoglycerate kinase 1 (PGK1) is an important enzyme in the metabolic glycolysis pathway. In this study, we observed a significant overexpression of PGK1 in liver cancer tissues and a negative correlation between PGK1 expression and liver cancer patient survival. Furthermore, depletion of PGK1 dramatically reduced cancer cell proliferation and(More)
Although calreticulin (CRT) is a major Ca(2+)-binding luminal resident protein, it can also appear on the surface of various types of cells and it functions as an immunopotentiating molecule. However, molecular mechanisms underlying the potent immunobiological activity of cell surface CRT are still unclear. In the present study, a recombinant fragment(More)
To examine the incorporation of anti-CCP antibodies into the American College of Rheumatology (ACR) classification criteria for rheumatoid arthritis (RA) and to evaluate the advantages of the revised anti-CCP criteria in diagnosing Chinese patients. Patients who suffered from arthritic problems during the recent 2 years were selected from the Department of(More)
F-box and WD repeat domain-containing 7 (FBW7) is the substrate recognition component of the Skp1-Cul1-F-box (SCF) ubiquitin ligase complex and functions as a major tumor suppressor by targeting various oncoproteins for degradation. Genomic deletion or mutation of FBW7 has frequently been identified in many human cancers but not in pancreatic ductal(More)
OBJECTIVES The deletion of LCE3C_LCE3B confers susceptibility to psoriasis and rheumatoid arthritis (RA) in Caucasians. The aim of this study was to investigate the variant involvement in RA in the Chinese Han population and to further explore its potential role in the susceptibility to systemic lupus erythematosus (SLE). METHODS LCE3C_LCE3B-del was(More)
OBJECTIVE Leukocyte immunoglobulin-like receptor A3 belongs to a family of receptors with inhibitory or activating functions. Since Caucasian individuals lacking LILRA3 have been found to be susceptible to multiple sclerosis and Sjögren's syndrome, we undertook this study to examine whether LILRA3 deletion is a novel genetic risk factor for rheumatoid(More)
OBJECTIVES To develop classification criteria for early rheumatoid arthritis (ERA) based on a large cohort of early inflammatory arthritis patients and to evaluate the performance of these criteria. METHODS The study population comprised a cohort of early inflammatory arthritis patients with symptom duration less than one year. Classification criteria of(More)
Cytokines play a key role in the bone destruction of rheumatoid arthritis (RA). Interleukin-21 (IL-21) promotes osteoclastogenesis in RA in a receptor activator of nuclear factor-κB ligand (RANKL)-dependent way. Whether IL-21 is capable of promoting osteoclastogenesis directly in the absence of RANKL remains unknown. In the present study, we examined the(More)
