Abstract
Stereocaulon alpinum has been found to have potential pharmaceutical properties due to the presence of secondary metabolites such as usnic acid, atranorin, and lobaric acid (LA) which have anticancer activity. On the other hand, the effect of LA on the stemness potential of colorectal cancer (CRC) cells remains unexplored, and has not yet been thoroughly investigated. In this study, we examined the inhibitory activity of LA from Stereocaulon alpinum against the stemness potential of CRC cells and investigated the possible underlying mechanisms. The results demonstrated that LA did not inhibit the cell viability of CSC221 and DLD1. In addition, LA significantly decreased the spheroid formation of CSC221 and DLD1. Moreover, LA treatment suppressed cancer stem cell (CSC) markers; aldehyde dehydrogenase 1 (ALDH1), B-cell-specific Moloney leukemia virus insertion site 1 (BMI1), musashi1 (MSI1), and leucine-rich repeat-containing G-protein coupled receptor 5 (Lgr5), along with the sonic hedgehog (Shh) and mTOR/AKT pathways that contribute significantly to maintaining the stemness of CRC cells. Therefore, LA may be a new therapeutic approach for reducing the stemness of CRC cells.
期刊介绍:
BioFactors, a journal of the International Union of Biochemistry and Molecular Biology, is devoted to the rapid publication of highly significant original research articles and reviews in experimental biology in health and disease.
The word “biofactors” refers to the many compounds that regulate biological functions. Biological factors comprise many molecules produced or modified by living organisms, and present in many essential systems like the blood, the nervous or immunological systems. A non-exhaustive list of biological factors includes neurotransmitters, cytokines, chemokines, hormones, coagulation factors, transcription factors, signaling molecules, receptor ligands and many more. In the group of biofactors we can accommodate several classical molecules not synthetized in the body such as vitamins, micronutrients or essential trace elements.
In keeping with this unified view of biochemistry, BioFactors publishes research dealing with the identification of new substances and the elucidation of their functions at the biophysical, biochemical, cellular and human level as well as studies revealing novel functions of already known biofactors. The journal encourages the submission of studies that use biochemistry, biophysics, cell and molecular biology and/or cell signaling approaches.
