Figure 4. PO2-evoked activation of NF-κB.

Figure 4

FDLE cells in monolayer culture were first maintained at fetal PO2 and then transferred into the adult alveolar environment in order to impose a shift in PO2 equivalent to that seen at birth. Nuclear protein was extracted 0-96 h after the imposition of this shift in PO2, and the effects of this manoeuvre upon NF-κB activity determined (see Methods). A, representative images which together show the PO2-evoked changes in NF-κB activity over the time course of this experiment. B, pooled data (means ±s.e.m., n = 4) showing the time course of the PO2-evoked changes in NF-κB activity.
