In addition, by searching the Oncomine database, we found the highest GRP78 expression levels in chemo-resistant cancer cells, moderate GRP78 expression levels in intermediate chemo-sensitive cells, and the lowest GRP78 expression levels in chemo-sensitive cells such as the Gyorffy cell line and Schaefer Sarcoma research cell line [28,29] (Figure 3C,D). This evidence concerns the gene HSPA5 and cancer.
