Upregulation of FSCN1 protein expression has been found in many cancers, such as esophageal cancer [24], non-small-cell lung cancer [25], breast cancer [26], gastric cancer [27], pancreatic ductal adenocarcinoma [28], and adrenal cortical cancer [29], so we speculate that FSCN1 may play an important role in the malignant transformation of OC [30]. Here, FSCN1 is linked to pancreatic ductal adenocarcinoma.
