BAP31 is an endoplasmic reticulum protein-sorting factor that associates with newly synthesized integral membrane proteins and controls their fate (i.e., egress, retention, survival, or degradation). BAP31 is itself an integral membrane protein and a constituent of several large protein complexes. Here, we show that a part of the BAP31 population interacts(More)
Vascular endothelial growth factor (VEGF)-C is a lymphangiogenic factor implicated in lymphatic metastasis. In this study, we investigated the role of the type I insulin-like growth factor receptor (IGF-IR) in the regulation of VEGF-C expression. We used Lewis lung carcinoma subline M-27 cells transfected with human IGF-IR cDNA. These cells, but not the(More)
BACKGROUND Many genetic diseases are due to defects in protein trafficking where the mutant protein is recognized by the quality control systems, retained in the endoplasmic reticulum (ER), and degraded by the proteasome. In many cases, the mutant protein retains function if it can be trafficked to its proper cellular location. We have identified(More)
Most cases of cystic fibrosis (CF) are caused by the deletion of a single phenylalanine residue at position 508 of the cystic fibrosis transmembrane conductance regulator (CFTR). The mutant F508del-CFTR is retained in the endoplasmic reticulum and degraded, but can be induced by low temperature incubation (29°C) to traffic to the plasma membrane where it(More)
To evaluate the telomere/telomerase system and its clinical significance in immune thrombocytopenia (ITP) patients. A total of 237 ITP patients, 20 SLE patients and 200 age-and sex-matched healthy controls were included in this study. CD4+, CD8+ and CD19+ lymphocytes were purified by magnetic beads sorting from peripheral blood of 37 active chronic ITP(More)
The TAM kinase (Tyro3, Axl, Mer) and its two ligands (Gas6 and protein S) have been shown to play an important regulatory role in the innate immune response. The present study aimed to investigate whether the tag single-nucleotide polymorphisms (tag SNPs) of these 5 protein-coding genes are associated with Behçet's disease (BD). A two-stage association(More)
Autoreactive T cells in immune thrombocytopenia (ITP) patients undergo a rapid clonal expansion and are resistant to apoptosis to maintain continuous effect in thrombocytopenia. As Bmi-1 is involved in memory CD4+ T cell survival and Th2 proliferation, we hypothesized that Bmi-1 may have a role in autoreactive CD4+ T cell clonal expansion and Th1/Th2(More)
