IGF2BP2 promotes colorectal cancer progression by upregulating the expression of TFRC and enhancing iron metabolism.

Background: Colorectal cancer (CRC) is one of the most common malignant tumors of the digestive system, ranking third for morbidity and mortality worldwide. At present, no effective control method is available for this cancer type. In tumor cells, especially iron metabolization, is necessary for its growth and proliferation.

Construction and evaluation of DNA vaccine encoding Crimean Congo hemorrhagic fever virus nucleocapsid protein, glycoprotein N-terminal and C-terminal fused with LAMP1.

Crimean-Congo hemorrhagic fever virus (CCHFV) can cause severe hemorrhagic fever in humans and is mainly transmitted by ticks. There is no effective vaccine for Crimean-Congo hemorrhagic fever (CCHF) at present. We developed three DNA vaccines encoding CCHFV nucleocapsid protein (NP), glycoprotein N-terminal (Gn) and C-terminal (Gc) fused with lysosome-associated membrane protein 1 (LAMP1) and assessed their immunogenicity and protective efficacy in a human MHC (HLA-A11/DR1) transgenic mouse model.

Transcriptome Based System Biology Exploration Reveals Homogeneous Tumorigenicity of Alimentary Tract Malignancy.

Malignancies of alimentary tract include esophageal carcinoma (ESCA), stomach adenocarcinoma (STAD), colon adenocarcinoma (COAD), and rectum adenocarcinoma (READ). Despite of their similarities in cancer development and progression, there are numerous researches concentrating on single tumor but relatively little on their common mechanisms. Our study explored the transcriptomic data of digestive tract cancers from The Cancer Genome Atlas database, yielding their common differentially expressed genes including 1,700 mRNAs, 29 miRNAs, and 362 long non-coding RNAs (lncRNAs).

Hantavirus Gc induces long-term immune protection via LAMP-targeting DNA vaccine strategy.

Hemorrhagic fever with renal syndrome (HFRS) occurs widely throughout Eurasia. Unfortunately, there is no effective treatment, and prophylaxis remains the best option against the major pathogenic agent, hantaan virus (HTNV), which is an Old World hantavirus. However, the absence of cellular immune responses and immunological memory hampers acceptance of the current inactivated HFRS vaccine.

Recombinant DNA vaccine of Hantavirus Gn and LAMP1 induced long-term immune protection in mice.

Background: Prophylaxis is widely adopted the best choice against Hemorrhagic fever with renal syndrome (HFRS) caused by Hantavirus. However, loss of memory immune response maintenance remains as major shortcoming in current HFRS vaccine. A recombinant DNA vaccine, pVAX-LAMP/Gn was previously proved efficient, requiring long-term evaluations.

Construction and evaluation of DNA vaccine encoding Hantavirus glycoprotein N-terminal fused with lysosome-associated membrane protein.

Background: Hantaviral diseases can have a high case fatality rate within the absence of broadly effective antiviral treatments or vaccines. We developed a DNA vaccine targeting the Hantavirus glycoprotein N-terminal (Gn) to major histocompatibility complex class II compartment by fusing the antigen with lysosome-associated membrane protein 1 (LAMP1), which altered antigen presenting pathway and activated the CD4+ T cells.

Methods: The segments of Gn and LAMP1 were cloned into vector pVAX1, and recombinant plasmid was constructed by inserting Gn sequence into LAMP1, between luminal and the transmembrane/cytoplasmic domains.

Intestinal permeability of forskolin by in situ single pass perfusion in rats.

The intestinal permeability of forskolin was investigated using a single pass intestinal perfusion (SPIP) technique in rats. SPIP was performed in different intestinal segments (duodenum, jejunum, ileum, and colon) with three concentrations of forskolin (11.90, 29.

[Role of dendritic cells in the pathogenesis of asthma in children].

Unlabelled: Dendritic cells (DC) are very potent antigen-presenting cells (APC) with a unique ability to activate naive T cells to induce the differentiation of TH1/TH2. Monocytes can develop into DC in the presence of different cytokines such as granulocyte-macrophage colony-stimulating factor (GM-CSF) and IL-4. DCs are thought to play a key role in the initiation and maintenance of T cell immunity to inhaled antigens.
