We therefore examined the human prostate cancer cell lines DU145, PC3, and LNCaP for expression of HK2 and found that the PTEN-deficient PC3 and LNCaP cells expressed higher levels of HK2 compared with the PTEN-proficient DU145 cells (Figure 5A and Figure 5—figure supplement 1). The gene discussed is HK2; the disease is prostate cancer.
