Secretory Mucin 5AC Promotes Neoplastic Progression by Augmenting KLF4-Mediated Pancreatic Cancer Cell Stemness

Newsfeed image, light gray text on dark gray background
Secreted mucin 5AC (MUC5AC) is the most abundantly overexpressed member of the mucin family during early pancreatic intraepithelial neoplasia stage I (PanIN-I) of pancreatic cancer (PC). To comprehend the contribution of Muc5ac in PC pathology, we genetically ablated it in an autochthonous murine model (KrasG12D; Pdx-1cre, KC), which mirrors the early stages of PC development.

Neoplastic onset and the PanIN lesion progression were significantly delayed in Muc5ac knockout (KrasG12D; Muc5ac-/-; Pdx-1cre, KCM) animals with a 50% reduction in PanIN-2 and 70% reduction in PanIN-3 lesions compared to KC at 50 weeks of age. Read more . . .
