Photothermolysis Mediated by Gold Nanorods Conjugated with Epidermal Growth Factor Receptor (EGFR) Monoclonal Antibody Induces Apoptosis via the Mitochondrial Apoptosis Pathway in Laryngeal Squamous Cell Cancer.

Gold nanorods (AuNRs) have unique optical properties and biological affinity and can be used to treat tumors when conjugated with other protein molecules. Our previous studies have shown that EGFR monoclonal antibody (EGFRmAb)-modified AuNRs exert strong antitumor activity by inducing apoptosis. In this study, we tested the effects of EGFRmAb-modified AuNRs on laryngeal squamous cell cancer (LSCC) and .

The Yunnan national medicine Maytenus compound inhibits the proliferation of hepatocellular carcinoma (HCC) by suppressing the activation of the EGFR-PI3K-AKT signaling pathway.

To investigate the effects of Maytenus compound on the proliferation of hepatocellular carcinoma (HCC) cells and and to explore the underlying mechanism. The half maximal inhibitory concentration (IC50) values of Maytenus compound in HepG2 and BEL-7402 cells were determined by the MTS assay. HepG2 and BEL-7402 cells were treated with different concentrations of Maytenus compound.

CD19 and CD30 CAR T-Cell Immunotherapy for High-Risk Classical Hodgkin's Lymphoma.

Background: In clinical applications of CAR T-cell therapy, life-threatening adverse events including cytokine release syndrome and neurotoxicity can lead to treatment failure. Outcomes of patients treated with anti-CD30 CAR T- cell have been disappointing in relapsing/refractory (r/r) classical Hodgkin's Lymphoma (cHL).

Methods: In order to understand the applicable population of multiple CAR T-cell therapy, we examined the expression of CD19, CD20, and CD30 by immunohistochemistry (IHC) in 38 paraffin-embedded specimens of cHL.

Viral IL-10 down-regulates the "MHC-I antigen processing operon" through the NF-κB signaling pathway in nasopharyngeal carcinoma cells.

The HLA-I antigen processing machinery (APM) plays a crucial role in the anticancer immune response. The loss of surface expression of HLA-I molecules is particularly important as this enables tumor cells to evade recognition and lysis by cytotoxic T-lymphocytes. Transcriptional control of the APM genes is regulated by the nuclear factor kappa B (NF-κB).

Downregulation of expression of transporters associated with antigen processing 1 and 2 and human leukocyte antigen I and its effect on immunity in nasopharyngeal carcinoma patients.

The human leukocyte antigen (HLA)-I and antigen-processing machinery (APM) are crucial in the anti-cancer immune response. The aim of this study was to assess the clinical significance of the APM components [transporters associated with antigen processing (TAP)-1 and -2 and HLA-I] in nasopharyngeal carcinoma (NPC). A total of 58 NPC specimens and 20 healthy specimens used as control were evaluated by semiquantitative immunohistochemistry for three APM components (TAP-1, TAP-2 and HLA-I).

[Anatomical study of improved lateral arm free flap].

Objective: To study the anatomy and preparation methods of an improved lateral arm free flap (LAFF) for the future clinical application.

Methods: Twenty-two adult upper extremities from cadavers after injected with red latex through common carotid arteries were used. The course, branches, distribution and variations of the blood vessels and nerves of the improved LAFF were observed.
