At a 72 h time-point, a subtle but significant elevation of HMOX1 was observed in response to SD exposure (1.3-fold, p < 0.05 and 1.4-fold, p < 0.001 for 5 and 50 μg/mL doses, respectively); to 50 μg/mL dose for AD and pollen (1.4-fold, p < 0.001 and 1.3-fold, p < 0.01, respectively); and after both doses of TE (1.7-fold, p < 0.001 and 2.0-fold, p < 0.001, respectively). The gene discussed is HMOX1; the disease is Alzheimer disease.
