In addition, based on the databases of The Cancer Genome Atlas and Gene Expression Omnibus, combined with the analysis of breast tumor and adjacent nontumor tissues in the clinical cohort, a previous study has also reported a higher expression of FER1L4 in tumorous tissues, which may be associated with worse disease outcomes and may trigger chemoresistance and tumorigenesis in human cancer.25 Here, FER1L4 is linked to cancer.
