To detect the potential mechanism pattern of lncRNA FOXP4-AS1 in PCa, we detected the cellular localization of FOXP4-AS1 in PCa cells and determined that FOXP4-AS1 was predominantly located in the cytoplasm of PCa cells, indicating that FOXP4-AS1 may regulate gene expression at post-transcriptional level. This evidence concerns the gene FOXP4 and posterior cortical atrophy.
