Broad institute gene expression database (https://portals.broadinstitute.org/ccle/page?gene=BIK (accessed on 9 October 2020)) shows relatively high levels of BIK mRNA in prostate cancer cells, yet there are very few reports on the role of BIK in apoptosis regulation in prostate cancer cells [155,156], and no data on BIK protein levels in prostate tumors. Here, BIK is linked to prostate carcinoma.
