Figure 6.

Effect of UV-irradiation on mRNA expression of Grp94 and Grp78 in RPMI 8226 cells. RPMI 8226 cells were subjected to UV-irradiation at 120 mJ/cm2 and RNA was extracted 1, 15, 60 and 120 minutes. Real-time PCR using actin and grp78 (A) or grp94 (B) primers was performed and data is expressed as calibrator corrected and actin normalized ratios.
