This further releases the established p65:p50 heterodimer complex into the nucleus, resulting in the transcription of downstream target genes.[27] NF‐κB activates the transcription of HuR in human gastric cancer cell lines.[28] We employed the inhibitor IMD 0354 to investigate involvement of the NF‐κB pathway in HuR transcription in primary CFs. Here, NFKB1 is linked to gastric cancer.
