AI Article Synopsis
Article Abstract
Modulating the surface properties of nanoparticles (NPs) is an important approach to accomplish immune escape, prolonged the blood retention time, and enhance the ability of targeted drug delivery. The camouflage of cancer cell membrane onto nanoparticles has been proved to be an ideal approach to enhance active targeting ability of NPs. Herein, we isolated the membrane of melanoma cells to coat doxorubicin (DOX) and indocyanine green (ICG)-loaded hollow copper sulfide NPs (ID-HCuSNP@B16F10) for targeted photothermal therapy, photoacoustic imaging, and chemotherapy. A remarkable in vitro anticancer effect after irradiation and homologous targeting can be observed in B16F10 cells after the treatment of ID-HCuSNP@B16F10. Moreover, ID-HCuSNP@B16F10 exhibits excellent photothermal effect in melanoma animal models and achieves a high tumor ablation rate. This biomimetic system can realize high drug loading efficiency, enhanced targeting ability, and ideal antitumor efficiency.

Adaptive immune resistance in cancer describes the various mechanisms by which tumors adapt to evade anti-tumor immune responses. IFN-γ induction of programmed death-ligand 1 (PD-L1) was the first defined and validated adaptive immune resistance mechanism. The endoplasmic reticulum (ER) is central to adaptive immune resistance as immune modulatory secreted and integral membrane proteins are dependent on ER.

The outer membrane is the defining structure of Gram-negative bacteria. We previously demonstrated that it is a major load-bearing component of the cell envelope and is therefore critical to the mechanical robustness of the bacterial cell. Here, to determine the key molecules and moieties within the outer membrane that underlie its contribution to cell envelope mechanics, we measured cell-envelope stiffness across several sets of mutants with altered outer-membrane sugar content, protein content, and electric charge.

Background: Rex rabbit is famous for its silky and soft fur coat, a characteristic predominantly attributed to its hair follicles. Numerous studies have confirmed the crucial roles of mRNAs and non-coding RNAs (ncRNAs) in regulating key cellular processes such as cell proliferation, differentiation, apoptosis and immunity. However, their involvement in the regulation of the hair cycle in Rex rabbits remains unknown.

Background: Vocal fold leukoplakia (VFL), a precancerous lesion of the larynx, is characterized by white plaques on the vocal fold mucous membrane. Currently, there are no reliable biomarkers to predict the recurrence and malignant transformation of VFL. Considering chondroitin sulfate proteoglycan 4 (CSPG4) as a biomarker for malignant tumors such as laryngeal squamous cell carcinoma (LSCC), we conducted this cohort study to evaluate the prognostic influence of CSPG4 expression on VFL patients.

Recent studies have suggested that sVEGFR3 is involved in cardiac diseases by regulating lymphangiogenesis; however, results are inconsistent. The aim of this study was to investigate the function and mechanism of sVEGFR3 in myocardial ischemia/reperfusion injury (MI/RI). sVEGFR3 effects were evaluated in vivo in mice subjected to MI/RI, and in vitro using HL-1 cells exposed to oxygen-glucose deprivation/reperfusion.
