Grp94 mRNA expression status in primary oral squamous cell carcinomas (OSCCs) and OSCC-derived cell lines. (A) Comparison of Grp94 mRNA expression levels between Grp94-positive and Grp94-negative cases classified by immunohistochemical analysis. There is a significant difference in the Grp94 mRNA expression levels between the negative and positive cases (P<0.001, Mann–Whitney's U-test). (B) Quantification of mRNA levels in OSCC-derived cell lines by qRT–PCR analysis. Significant upregulation of Grp94 mRNA expression is seen in all OSCC-derived cell lines examined compared to normal oral epithelium. Data are expressed as the means±s.d.
