As shown in Figure 6A–D, CXCL12 treatment also resulted in increases in the levels of phospho‐p38 and phospho‐ERK in both NIT‐1 cells and RIN‐m5F insulinoma cells, while p38 and ERK expression did not significantly differ between PBS‐treated and CXCL12‐treated cells. The gene discussed is CXCL12; the disease is pancreatic insulinoma.
