Abstract
Leukemia/lymphoma related factor (LRF), also known as Pokemon, is a protein that belongs to the POK family of transcriptional repressors. It has an oncogenic role in many different solid tumors. In this study, the expression of LRF was evaluated in benign prostate hyperplastic (BPH) and prostate cancer (PC) tissues. The functional expression of LRF was studied using multiple cellular and molecular methods including RT-PCR, western blotting, immunohistochemistry, and immunofluorescence. Paraffin-embedded human tissues of BPH and PC were used to examine LRF expression. Histological staining of the BPH and PC tissue sections revealed nuclear expression of LRF with minimal expression in the surrounding stroma. The semi-quantitative RT-PCR and western immunoblot analyses demonstrated significantly higher mRNA transcripts and protein expression in PC than BPH. High expression of LRF suggests that it may have a potential role in the pathogenesis of both BPH and prostate cancer. Further studies will help elucidate the mechanisms and signaling pathways that LRF may follow in the pathogenesis of prostate carcinoma.
