CD166/ALCAM plays an important role in tumor aggression and progression as well as protecting cancer cells against apoptosis and autophagy. However, the mechanism by which pro-cell death signals control CD166 expression remains unclear. Here we show that following serum deprivation (SD), upregulation of CD166 protein is shorter than that of CD166 mRNA.(More)
Cluster of differentiation 166 (CD166 or Alcam) is a cell surface molecule that can be greatly induced in liver cancer cells after serum deprivation, suggesting its role in influencing cell survival. However, whether and how CD166 acts as an anti-apoptotic regulator needs to be further investigated. Here, we report that gene silencing of CD166 promoted(More)
IL -10 is widely accepted as a survival, proliferation, and differentiation factor for B cells. However, IL-10 deficiency accelerates disease progression as the result of autoantibody production in many autoimmune disease models. It was demonstrated that T follicular helper cells (T(FH) cells) play a key role in helping B cells that are secreting Abs. In(More)
Mounting evidence suggests that the FAK N-terminal (FERM) domain controls FAK phosphorylation and function; however, little is known regarding the role of the C terminal (FAT) domain in FAK regulation. We identified a patient-derived FAK mutant, in which a 27-amino acid segment was deleted from the C-terminal FAT domain (named FAK-Del33). When FAK-Del33 was(More)
T cell antiviral function is impaired during chronic hepatitis B (CHB). Programmed death-1 (PD-1) impairs antiviral T cell responses, but dysfunction is not always reversed by blockade of PD-1 pathway. Whether distinct T cell populations expressing different sets of inhibitory molecules exist has not been determined. We studied the expression of the B and T(More)
BACKGROUND We evaluated the diagnostic value of serum-CD166 in patients with hepatocellular carcinoma (HCC). METHODS Tissue-CD166 was measured using immunohistochemistry. Cell proliferation and migration were evaluated using MTT and Transwell assays, respectively. Serum-CD166 was examined using ELISA and western blotting. RESULTS CD166 was up-regulated(More)
Similar to programmed death-1 (PD-1), B and T lymphocyte attenuator (BTLA) is a co-inhibitory molecule of the CD28 family. PD-1 is involved in T cell exhaustion during chronic viral infection. However, the role of BTLA in virus-specific T cells is poorly defined. Here we investigated the expression and function of BTLA in T cells from patients with chronic(More)
