Compared with normal ovaries (19.96 × 104 ± 3.5 × 104), the intensity of GRP78 expression was significantly (p < 0.03) higher in malignant tumors at early stages, including serous (34.70 × 104 ± 2.58 × 104), endometrioid (32.15 × 104 ± 2.91 × 104) and mucinous (34.60 × 104 ± 4.0 × 104) in 20 mm2 area of tissue (Figure 6D). Here, HSPA5 is linked to cancer.
