IL6 and asthma: Recent studies have reported that the lncRNA PVT1 is involved in asthma.[27] PVT1 is decreased in patients with corticosteroid-sensitive nonsevere asthma and increased in patients with corticosteroid-insensitive severe asthma, and subsequent targeting studies demonstrated the importance of this lncRNA in controlling both proliferation and IL-6 release in ASMCs from patients with severe asthma.[28] We identified PVT1 in our study, but noted no difference between samples.
