Background: Non-small-cell lung cancer (NSCLC) is the most prevalent cancer worldwide. Tumor microenvironment (TME) plays a very important role in the cancer development. Thus, it is urgent to find the change of TME that contributes to NSCLC carcinogenesis and progression. Methods: The bioinformatics analysis approach was applied to evaluate the...
Article
Lung cancer is the most frequent malignant tumor, and non-small cell lung cancer (NSCLC) is responsible for substantial mortality worldwide. The small molecule SNX-2112 was recently shown to critically effect the proliferation and apoptosis of tumor cells. Nevertheless, the precise mechanism by which SNX-2112 affects NSCLC remains poorly understood...

The efficacy of chimeric antigen receptor (CAR) T is still not optimal for solid tumors, partly due to the lack of T-cell infiltration to the tumor site. One promising strategy is to guide T cells through tumor-specific chemokines, provided that the matching chemokine receptors are expressed on T cells. Previous reports showed that, for non-small c...

Background: Although single-drug chemotherapy is still an effective treatment for esophageal cancer, its long-term application is limited by severe side-effects, poor bioavailability, and drug-resistance. Increasing attention has been paid to nanomedicines because of their good biological safety, targeting capabilities, and high-efficiency loading...
Article
The NF-E2–related factor 2 (referred to as NRF2) transcription factor binds antioxidant responsive elements within the promoters of cytoprotective genes to induce their expression. Next-generation sequencing studies in lung cancer have shown a significant number of activating mutations within the NRF2 signaling pathway. Mutations in components of t...

Fibronectin 1 (FN1) is a member of the glycoprotein family located on chromosome 2q35. It has been reported that FN1 is upregulated in many tumors, and its expression is negatively related to the prognosis and survival of cancer patients. Through data analysis, we found that FN1 is upregulated in nasopharyngeal carcinoma (NPC). This study aimed to...

Almost all viral pathogens utilize a cytoskeleton for their entry and intracellular transport. In HIV-1 infection, binding of the virus to blood resting CD4 T cells initiates a temporal course of cortical actin polymerization and depolymerization, a process mimicking the chemotactic response initiated from chemokine receptors. The actin depolymeriz...

Persistence of human immunodeficiency virus (HIV) despite highly active antiretroviral therapy (HAART) is a lasting challenge to virus eradication. To develop a strategy complementary to HAART, we constructed a series of Rev-dependent lentiviral vectors carrying diphtheria toxin A chain (DT-A) and its attenuated mutants, as well as human tumor necr...

Previous studies demonstrated that the nef gene is a critical determinant of the pathogenicity of simian immunodeficiency virus (SIV) in macaques. In the present study, we evaluated the effect of a spontaneous frameshift mutation in the C-terminus of the nef gene of the minimally pathogenic SIVsmH4i clone. This clone exhibited a single nucleotide d...

We have previously demonstrated that binding of HIV-1 to the chemokine coreceptor, CXCR4, on resting CD4 T cells activates an actin-depolymerizing factor cofilin to promote the cortical actin dynamic critical for HIV latent infection [1]. The LIM domain kinase 1 (LIMK1) directly phosphorylates cofilin and regulates the actin cytoskeleton. Here, we...
