The immunological comparison of control PDA tumors and Krt19-edited PDA tumors

Our studies indicate that cancer cells of carcinomas are coated with CXCL12 chemokine in covalent conjugation with keratin-19 (KRT19). Murine pancreatic ductal adenocarcinomas (PDA) formed with Krt19-edited cancer cells lack the CXCL12-coating and are infiltrated with T cells, compared to tumors formed with control sgScramble PDA cells. To probe the immunological role of this CXCL12-coating thoroughly, bulk RNA sequencing of subcutaneous (s/c) murine sgScramble PDA tumors and Krt19-edited PDA tumors were conducted. Overall design: sgScramble PDA tumors vs sgKrt19 PDA tumors
