Abstract |
The senescence-associated protein p16INK4A acts as a limiter element in cell-cycle progression. The loss of p16INK4A function is causally related to cellular immortalization. The increase in p16INK4A levels with advancing age was demonstrated in melanocytes. However, the characteristic difference between young and senescent melanocytes affecting immortalization of melanocytes remains unclear. In this study, we generated 10 different cell lines in total from newborn (NB) and adult (AD) primary normal human epidermal melanocytes (NHEM) using four different methods, transduction of CDK4R24C and cyclin D1 (K4D), K4D with TERT (K4DT), SV40 T-antigen (SV40T), and HPV16 E6 and E7 (E6/E7) and performed whole transcriptome sequencing analysis (RNA-Seq) to elucidate the differences of genome-wide expression profiles among cell lines. The analysis data revealed distinct differences in expression pattern between cell lines from NB and AD although no distinct biological differences were detected in analyses such as comparison of cell morphology, evaluation of cell proliferation, and cell cycle profiles. This study may provide useful in vitro models to benefit the understanding of skin-related diseases.
