General description
一种细胞可渗透且可逆硬脂酸的13-氨基酸的肽，对应于MEK1（MAPKK）的N末端，可作为ERK激活的特异性抑制剂，并阻断Elk1的转录活性。选择性地与ERK2结合，并阻止其与MEK的交互效应（IC50 = 2.5 µM）。可有效阻断在PMA刺激的NIH 3T3细胞和NGF处理的PC12细胞（IC50 = 13 µM）中的ERK活性。不影响JNKs或p38的活性。

Pancreatic ductal adenocarcinoma (PDAC) frequently metastasizes into the peritoneum, which contributes to poor prognosis. Metastatic spreading is promoted by cancer cell plasticity, yet its regulation by the microenvironment is incompletely understood. Here, we show that the presence of hyaluronan and
