ZFP36L1 and asthma: To further investigate the dysregulation of both ZFP36L1 and ZFP36L2 mRNA levels in human (Figure 1) and mouse asthma (Figure 3; Figure 4) we performed immunostaining of ZFP36L1 and ZFP36L2 in bronchial biopsies from patients with different asthma severities and non-asthma controls.
