Nuclear issue kappa-B (NF-B), a pivotal transcription factor, is activated within the setting of injury and repair and is central to innate immunity. We’ve previously established that HCA BO2 biological activity protects against ventilation-induced lung injury in vivo, potentially via a mechanism involving inhibition of NF-B signaling. We wished to further elucidate the part and mechanism of HCA-mediated inhibition of the NF-B pathway in attenuating stretch-induced injury in vitro. Techniques: Initial experiments examined the effect of HCA on cyclic stretch-induced inflammation and injury in human bronchial and alveolar epithelial cells. Subsequent experiments examined the role with the canonical NF-B pathway in mediating stretchinduced injury plus the mechanism of action of HCA. The contribution of pH versus CO2 in mediating this impact of HCA was also examined. Benefits: Pulmonary epithelial high cyclic stretch (22 equibiaxial strain) activated NF-B, enhanced interleu.Ed with PBS, and resuspended in PBS containing 50 g/mL PI, 0.1 Triton X-100 (v/v), and 1 g/mL DNase-free RNase.
