Application of recombinase polymerase amplification with lateral flow assay to pathogen point-of-care diagnosis.

Since the outbreak of the new coronavirus, point-of-care diagnostics based on nucleic acid testing have become a requirement for the development of pathogen diagnostics, which require the ability to accurately, rapidly, and conveniently detect pathogens. Conventional nucleic acid amplification techniques no longer meet the requirements for pathogen detection in low-resource, low-skill environments because they require specialist equipment, complex operations, and long detection times. Therefore, recombinant polymerase amplification (RPA) is becoming an increasingly important method in today's nucleic acid detection technology because it can amplify nucleic acids in 20-30 minutes at a constant temperature, greatly reducing the dependence on specialist equipment and technicians.

TIM-3 Participates in the Invasion and Metastasis of Nasopharyngeal Carcinoma via SMAD7/SMAD2/SNAIL1 Axis-Mediated Epithelial-Mesenchymal Transition.

Background: T-cell immunoglobulin and mucin domain-containing molecule-3 (TIM-3) was originally found to negatively regulate immune response and mediate immune escape in tumors. Subsequently, an increasing body of evidence has shown that TIM-3 exerts positive functions in the development and progression of several tumors. However, the role of TIM-3 in nasopharyngeal carcinoma (NPC) remains unknown.

A novel compound heterozygosity in Southern China: IVS-II-5 (G > C) and IVS-II-672 (A > C).

β-Thalassemia (β-thal) is a common hereditary anemia due to decreased or absent synthesis of the β-globin chains. Here, we report a patient found to be a novel compound heterozygote for the rare IVS-II-5 (G > C) (NG_000007.3: g.

Construction and characterization of an enhanced GFP-tagged TIM-1 fusion protein.

TIM-1 (also known as KIM-1 and HAVcr-1) is a type I transmembrane glycoprotein member of the TIM family that may play important roles in innate and adaptive immune responses. The overexpression of proteins associated with membrane proteins is a major obstacle to overcome in studies of membrane protein structures and functions. In this study, we successfully coupled the overexpression of the TIM-1 protein with a C-terminal enhanced green fluorescent protein (GFP) tag in Escherichia coli.

Construction and characterization of bifunctional TIM-3-EGFP fusion proteins.

T cell immunoglobulin mucin-3 (TIM-3) is the first surface molecule to be found that specifically identifies Th1 cells in both mice and humans, and it negatively regulates Th1 responses. TIM-3 protein is a type I membrane protein. Overexpression of membrane proteins is a major problem to overcome in studies of membrane protein structure and function.

Interactions of human T cell immunoglobin mucins with apoptotic cells.

T cell immunoglobulin mucin (TIM) family plays a key role in regulating immune responses. In this study, the interactions of human TIM family with apoptotic cells were evaluated in order to provide a foundation for further study on the roles of human TIM genes in apoptosis. Nine kinds of pEGFP-N1 eukaryotic expression vectors containing different lengths of the three members of human TIM genes for the expression of TIM-EGFP and the vectors for the expression of TIM-Fc fusion proteins were constructed.
