[EX A]: no

[EX Q]: Question: Are fragile histidine triad gene alterations essential for hepatocellular carcinoma development in South Korea?
Answer: Aberrant FHIT transcripts were more common in HCC tissues as compared to non-cancerous liver tissues. However, Fhit expression was lost or reduced in a minor fraction of HCC tissues, while it was strongly expressed in non-cancerous liver tissues. Therefore, our study suggests that FHIT plays a role in relatively few HCC cases in South Korea.
[EX A]: no

[EX Q]: Question: Is brd4 essential for IL-1β-induced inflammation in human airway epithelial cells?
Answer: Oxidative stress enhanced IL1β-induced IL-6 and CXCL8 expression was significantly reduced by Brd4 inhibition. Brd4 plays an important role in the regulation of inflammatory genes and provides a potential novel anti-inflammatory target.
[EX A]:
yes
