Table 1. Fraction of XBP-1 mRNA splicing as a percentage of total XBP-1 mRNA in bystander HL-7702 cells treated with Thapsigargin, BiP siRNA, or their combination before receiving ICCM from normoxic and hypoxic HepG2 cells. Data were calculated from the results in Fig. 5a and b.

^aP < 0.001 compared to control receiving the same ICCM.

^bP < 0.001 compared to BiP siRNA receiving the same ICCM.

^cP < 0.001 compared to Thapsigargin receiving the same ICCM.
