Figure 2From: Down-regulation of GRP78 is associated with the sensitivity of chemotherapy to VP-16 in small cell lung cancer NCI-H446 cells The expression of GRP78 at the protein level detected by Immunofluorescence in NCI-H446. (A): untreated (control) cells; (B): cells treated with 2 μM A23187 alone for 24 h; (C): cells pretreated with BAPTA-AM at 40 μM for 2 h prior to the addition of A23187 at 2 μM for 24 h. (D): cells treated with BAPTA-AM at 10 μM alone for 2 h.Back to article page
