CEBPA and small cell lung carcinoma: However, when detecting CEBPA expression, we noticed that the difference of the CEBPA mRNA expression levels in the SCLC cells from Cisplatin-treated mice and in H69 cells was not statistically significant (p > 0.05) (Figure 5A), whereas the CEBPA protein was undetectable in the SCLC cells from Cisplatin-treated mice, which was clearly detected in H69 cells (Figure 5B).
