Plastids are ideal subcellular hosts for the expression of transgenes and have been successfully used for the production of different biopolymers, therapeutic proteins and industrial enzymes. Phaeodactylum tricornutum is a widely used aquatic feed species. In this study, we focused on developing a high-efficiency plastid expression system for P.(More)
NLRC5 is an important regulator in innate immune responses. However, the ability of NLRC5 to inhibit NF-κB activation is controversial in different cell types. How dynamic modification of NLRC5 shapes NF-κB signaling remains unknown. We demonstrated that NLRC5 undergoes robust ubiquitination by TRAF2/6 after lipopolysaccharide treatment, which leads to(More)
Type I interferon (IFN) is an important component of antiviral innate immune signaling mediated by viral DNA and RNA recognition by the DNA sensor cGAS and RNA sensors RIG-I and MDA5. Activation of these DNA and RNA sensors leads to the recruitment of STING and MAVS, respectively, and converges on TANK-binding kinase 1 (TBK1) signaling for subsequent(More)
To determine whether a panel of multiple tumor-associated antigens (TAAs) would enhance antibody detection, the diagnostic value of autoantibodies to a panel of multiple TAAs in cancer has been evaluated. The TAAs used in this study was composed of eight TAAs including Imp1, p62, Koc, p53, C-myc, Cyclin B1, Survivin, and p16 full-length recombinant(More)
Traditional methods for protein kinase (PK) assay are mainly based on use of (32)P-labeled adenosine triphosphate (ATP); applications of such methods are, however, hampered by radioactive waste and short half-life of (32)P-labeled ATP. Therefore non-radioactive methods, such as fluorescence detection techniques are good alternative. In this review, we(More)
Dynamic analysis of viral nucleic acids in host cells is important for understanding virus-host interaction. By labeling endogenous RNA with molecular beacon, we have realized the direct visualization of viral nucleic acids in living host cells and have studied the dynamic behavior of poliovirus plus-strand RNA. Poliovirus plus-strand RNA was observed to(More)
Cervical ectopic thymus rarely occur. We reported a case of cervical thymus presenting as a unilateral neck mass in an infant. Ultrasonography showed a low echo-level mass with clear border and abundant blood flow signal in the left neck. Preoperative chest CT revealed normal structures in the superior mediastinum including the thymus. Surgical resection(More)
Glucose oxidase (GOD) was genetically modified by adding a poly-lysine chain at the C-terminal with a peptide linker inserted between the enzyme and poly-lysine chain. The poly-lysine chain was added in order to anchor more electron transfer mediator, ferrocenecarboxylic acid, to GOD for the purpose of improving sensitivity and stability of glucose(More)
Autophagy, mediated by a number of autophagy-related (ATG) proteins, plays an important role in the bulk degradation of cellular constituents. Beclin-1 (also known as Atg6 in yeast) is a core protein essential for autophagic initiation and other biological processes. The activity of Beclin-1 is tightly regulated by multiple post-translational modifications,(More)
The merits of molecular imprinting material are of specificity, high selectivity and high intensity. Reduced glutathione (GSH) is an important cofactor in the biological processes of metabolism and transportation. To find a suitable functional monomer and the best ratio to prepare GSH molecular imprinting polymer, we prepared mixtures of GSH and(More)
