Fig. 4From: Knockdown of circ_0006872 alleviates CSE-induced human bronchial epithelial cells injury in chronic obstructive pulmonary disease Knockdown of circ_0006872 attenuates CSE-induced 16HBEC injury via miR-485-3p. A–H 16HBECs were co-transfected with si-circ_0006872 and/or anti-miR-485-3p, followed by 2% CSE exposure for 24 h. A Transfection efficiency. B–D 16HBEC proliferation analysis. E 16HBEC apoptosis detection. F Levels of Bax and Bcl-2 in 16HBECs. G Levels of IL-6 and TNF-α in 16HBECs. H Measurement of SOD content in 16HBECs using a commercial kit. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001Back to article page
