Abstract:
:N-α-acetyltransferase 10 (Naa10) displays alpha (N-terminal) acetyltransferase activity. It functions as a major modulator of cell growth and differentiation. Until now, a few downstream targets were found, but no studies have concerned about which gene is the early event of Naa10 downstream target. As we know, the earlier events may play more significant role in Naa10 pathway. Through construction of Naa10 stably knocked down H1299 cell line, we discovered cell morphological changes induced by Naa10. Moreover, potential function of Naa10 in cell morphogenesis was also indicated using cDNA microarray analysis of the Naa10 stably knock-down cell line. We further discovered that netrin-1 (NTN1) and its receptor UNC-5 Homology B (UNC5B) were the early event among the genes involved in Naa10 stably knocked down induced genes expression changes in cell morphogenesis. This was further validated in caudal half region of E10 mouse embryos. Negative regulation of Naa10 towards NTN1 and its receptor UNC5B were also detected upon treatment of all-trans retinoid acid, which was often used to induce morphological differentiation.
