A1M and Hpx attenuates Grp78 and HO1 gene induction. Cells were treated with heme or heme + rA1M or equimolar amonts of heme + Hpx as described in the legend to Figure 8. Grp78 and HO1 expression was measured using qRT-PCR 3 and 16 h after the treatment (A–D). (A) Relative expressions of Grp78 in response to heme and heme + rA1M complex were determined by qRT-PCR, normalized to GAPDH. Grp78 levels of rA1M + heme treated cells were compared to those detected in heme challenged cells. Results are presented as mean ± SD of five independent experiments performed in duplicates. ∗∗∗p < 0.0001 using unpaired t-test (B) Relative expressions of Grp78 in response to heme and heme + Hpx complex were determined by qRT-PCR, normalized to GAPDH. Grp78 levels of Hpx + heme treted cells were compared to those detected in heme challenged cells. Results are presented as mean ± SD of five independent experiments performed in duplicates. ∗∗∗p < 0.0001 using unpaired t-test. (C) Relative expressions of HO1 in response to heme and heme + rA1M complex were determined by qRT-PCR, normalized to GAPDH. HO1 levels of rA1M + heme treated cells were compared to those detected in heme challenged cells. Results are presented as mean ± SD of five independent experiments performed in duplicates. ∗∗∗p < 0.0001 using unpaired t-test. (D) Relative expressions of HO1 in response to heme and heme + Hpx complex were determined by qRT-PCR, normalized to GAPDH. HO1 levels of Hpx + heme treted cells were compared to those detected in heme challenged cells. Results are presented as mean ± SD of five independent experiments. ∗∗∗p < 0.0001 using unpaired t-test.
