BAK1, Bcl-xL, CASPASE3, and TP53 are known regulators of apoptosis, and are related to the intrinsic mitochondrial apoptosis pathway.
To further test this finding, we evaluated the gene expression levels of all four apoptosis signaling-related genes predicted to be targeted by miR-125b, namely
BAK1, CASP2, MAP2K7, and MCL1.

TDF72 encodes a BRI1-associated receptor kinase 1 (
BAK1), a second LRR RLK that interacts with BRI1 in vitro, and may play an important role in BR signal transduction [64, 65].
The proapoptotic protein
Bak1 is a target to miR-125b, and interestingly, this protein has been shown to be decreased in hormone-refractory tumors (69).
The most significantly linked marker was identified as
BAK1 on BTA23 (Everts-van der Wind et al., 2004).
miR-125b, an androgen-sensitive miRNA in prostate cancer, has been reported to stimulate androgen-independent growth and to regulate apoptosis by inhibition of
BAK1 [encoded by BCL2-antagonist/killer 1 (
BAK1)] (12,47,48).
Genes with decreased expression in the cells included the proapoptotic gene
BAK1 and the cell cycle control gene p15INK4B.
