MAPK8 and Familial prostate cancer: The expression of pSAPK/JNK (Thr183/ Try185) was found to be high in the low LanCL1-expressing prostate cancer cell line LNCaP, whereas the expression was low in high LanCL1-expressing PC-3 and DU145 cells, indicating the inverse correlation between LanCL1 and p-JNK expression levels (Supplementary Figure 2E).
