MAP2K7 and familial pancreatic carcinoma: We present a nanoliter droplet array platform integrating synthesis, characterization, and cell‐based screening of 325 MEK (mitogen‐activated protein kinase kinase) inhibitors, targeting the MAPK/ERK (mitogen‐activated protein kinase/extracellular signal‐regulated kinase) pathway, implicated in colorectal and pancreatic cancer.
