Treatment with NDP-MSH increased phospho-CREB (p-CREB) expression in the peri-hematoma tissue at 24 h post-ICH, which increased the expression of downstream molecules including Nr4a1, ZO-1, occludin, and laminin-α5 (Lama5) and inhibited the expression of downstream inflammation-related proteins and MMP-9 (Fig. 5a-j), compared with ICH + vehicle group. The gene discussed is NR4A1; the disease is hematoma.
