Figure 4 shows tumor regions with cells that express high levels of miR-99a-5p. In the centers of the pancreatic tumors rich in epithelial cancer cells, there are no cells that express miR-99a-5p. When comparing the location of CD79A positive cells in the adjacent tissue slides, we observed that the miR-99a-5p expressing inflammatory cells are also in close proximity to cells of the B-cell lineage (Figure 4). The gene discussed is CD79A; the disease is pancreatic neoplasm.
