MACL-1 Breast Cancer Secretome Reprograms Fibroblasts to Enhance Inflammation and Tumor Progression.
Tumor-secreted factors reprogram the stromal microenvironment to facilitate cancer progression. This study investigates the effects of the MACL-1 breast cancer cell secretome on CCD19-Lu fibroblasts. Fibroblasts treated with the MACL-1 secretome exhibited increased proliferation, altered morphology, and upregulated expression of vimentin, NFκB, and fibroblast-activating protein, indicative of an inflammatory, activated phenotype. Additionally, elevated mitochondrial superoxide levels and an enrichment of proteases were detected in the secretome, but not in corresponding cell lysates. These findings suggest that the MACL-1 secretome promotes fibroblast activation and inflammation, underscoring its potential role in tumor-stroma interactions and breast cancer progression.
期刊介绍：
The Brazilian Academy of Sciences (BAS) publishes its journal, Annals of the Brazilian Academy of Sciences (AABC, in its Brazilianportuguese acronym ), every 3 months, being the oldest journal in Brazil with conkinuous distribukion, daking back to 1929. This scienkihic journal aims to publish the advances in scienkihic research from both Brazilian and foreigner scienkists, who work in the main research centers in the whole world, always looking for excellence.
Essenkially a mulkidisciplinary journal, the AABC cover, with both reviews and original researches, the diverse areas represented in the Academy, such as Biology, Physics, Biomedical Sciences, Chemistry, Agrarian Sciences, Engineering, Mathemakics, Social, Health and Earth Sciences.
