Proteinase-activated receptor-2 (PAR2) is closely linked to tumor malignancy, but its biological role in cancer remains underexplored. In this study, we assessed PAR2 expression in lung adenocarcinoma (LUAD) and normal lung tissues, analyzed associations between clinicopathological features and survival rates, and confirmed that PAR2 promotes apoptosis resistance and reduces cisplatin-induced cytotoxicity in lung cancer cells. Using TCGA datasets, western blotting, qPCR, and immunohistochemistry (IHC), we observed a significant increase in PAR2 levels in LUAD samples compared to normal tissues (P<0.

Widely used disposable plastic tableware is usually buried or directly discharged into the natural environment after using, which poses potential threats to the natural environment and human health. To solve this problem, nondegradable plastic tableware needs to be replaced by tableware composed of biodegradable structural materials with both food safety and the excellent mechanical and thermal properties. Here, a food-safe sargassum cellulose nanofiber (SCNF) is extracted from common seaweed in an efficient and low energy consuming way under mild reaction conditions.

This study investigated the role of ADAM metallopeptidase domain 12 (ADAM12) in clear cell renal cell carcinoma (ccRCC). The mRNA expression of ADAM12 was analyzed using The Cancer Genome Atlas (TCGA) database and the Gene Expression Omnibus (GEO) database, and the protein expression level of ADAM12 in renal clear cell carcinoma cell lines was detected by Western blot analysis. The Wilcoxon rank-sum test, logistic regression analysis, Cox regression analysis, and Kaplan-Meier analysis were used to assess the relationship between the clinicopathological characteristics and the prognosis of ccRCC patients and ADAM12 expression.
