In the study conducted by Jiang et al. 46, the researchers investigated the expression of Gal-3 and PTEN (phosphatase and tensin homologue) in PDAC, pancreatic neuroendocrine neoplasms (PNNs), and gastrointestinal tumours using fine-needle aspiration cytology (FNAC). This evidence concerns the gene LGALS3 and digestive system neoplasm.
