RELT and osteosarcoma: We consulted the Human Protein Atlas (HPA) [45] and found that RELT localized to the nucleoplasm in several cell lines representing prostatic adenocarcinoma (PC-3), rhabdomyosarcoma (RH-30), keratinocytes (HaCaT), and osteosarcoma (U-2 OS), although cytosolic staining was also observed in some of the cell lines such as PC-3 https://v23.proteinatlas.org/ENSG00000054967-RELT/subcellular (accessed on 15 November 2024.
