ESRRA and Familial prostate cancer: Finally, the expression of scavenger receptor B1 (SR-B1) encoded by SCARB1 gene, which is reported to facilitate the precursor cholesterol uptake as needed to drive steroidogenic and non-steroidogenic biogenic pathways in prostate cancer 34, showed no change in either LNCaP-ERRα or LNCaP-shERRα cells, suggesting that SR-B1-mediated precursor cholesterol uptake might not be affected by ERRα (Figure S4G).
