For instance, some key biomarkers have been exposed in pancreatic carcinoma, namely intercellular adhesion molecule 2 (ICAM2), anoctamin 9 (ANO9), proline-rich tyrosine kinase 2 (PYK2) and cyclin-dependent kinase 9 (CDK9) [7,8,9,10]. The gene discussed is PTK2B; the disease is exocrine pancreatic carcinoma.
