Fig. 2From: miR-34a in serum is involved in mild-to-moderate COPD in women exposed to biomass smokemiR-34a-5p is down-regulated in COPD-BS compared COPD-TS. RT-qPCR analysis of serum miR-34a-5p in women with COPD-TS compared with those with COPD-TS and presented as ΔCt values. n = 25. A statistical difference was observed between women with COPD-BS and women with COPD-TS. Student’s t-test was used. * P < 0.001. Abbreviations: COPD-TS, COPD due to tobacco smoke; COPD-BS, COPD due to biomass smoke.Back to article page
