To further confirm this speculation, we selected RelA as the representative to examine its nuclear localization in the other five cell lines including two pancreatic adenocarcinoma cell lines Panc‐28 and CFPAC‐1, a lung cancer cell line H1299, a breast cancer cell line MCF‐7, and a carcinoma cell line Fadu. The gene discussed is RELA; the disease is lung carcinoma.
