ELAVL1 and Patent ductus arteriosus: Additionally, Peng et al. attempted to correlate HuR’s expression with tumorigenesis by examining hematoxylin and eosin (H/E) sections from pancreata of TC mice older than 10 months old, without, however, any precancerous pancreatic intraepithelial neoplasia (PanIN) lesions or PDA being observed; this led to the conclusion that in the absence of any known driver of gene mutations, HuR overexpression alone does not initiate tumorigenesis [16].
