Differential expression pattern can be as small as 0.03-fold (uS4; TW01 versus NP69) to as large as 131.92-fold (eL18; SUNE-1 versus NP69). uS8, uS4, and uL14 are observed to be consistently underexpressed in all six NPC cell lines when compared to NP69, with the lowest expression observed in the SUNE-1 (0.07-fold), TW01 (0.03-fold), and SUNE-1 (0.17-fold) cell line, respectively. The gene discussed is RPS9; the disease is nasopharyngeal carcinoma.
