Exposure to PM₁₀ induces NF-κB activation through an alternate pathway in HAECs. (A) Cell lysates from HAECs exposed to PM₁₀ (40 μg/cm²) for 30 min to 4 hr or TNFα (20 ng/mL) for 15 min were immunoblotted using antibodies to p-NF-κBp65 (Ser 536), NF-κBp65 (Ser 536), and β-actin. Results are representative of three separate experiments. (B) Densitometric quantitation of p-p65 band optical density. Data are mean ± SE (n = 3). *p < 0.05.
