Immunohistochemistry of SAPK/JNK, p38, and pMAPK in control and LTPOC-treated human endometrium. Immunohistochemical staining for SAPK/JNK, p38, and pMAPK was conducted in human endometrium from control (proliferative phase) and endometrium exposed to high-dose intrauterine LNG (LTPOC) for 3 months. Studies were performed in paraffin-fixed sections as described in Materials and Methods. Antigens are identified by brown peroxidase staining. No staining was observed in the absence of primary antibody (not shown).
