<p>With the aim of studying the molecular mechanisms underlying lipid deposition in chickens, the expression profiles of eight novel candidate genes and miRNA involved in lipid deposition were examined in the undifferentiated and differentiated adipocyte at 3d, 5d and 10d after inducing differentiation. The level of expression of gga-miR-30 cluster (gga-miR-30a-5p, miR-30c-5p and miR-30e-5p) and miR-17-92 cluster (gga-miR-17-5p, miR-19a-3b and miR-20a-5p), compared to undifferentiated adipocyte, was significantly up-regulated with differentiated adipocyte; expression of miR-103-3p and miR-92-5p was significantly up-regulated with differentiated adipocyte. Seven genes, <i>ACSL1</i>, <i>CYB5A</i>, <i>SEC23A</i>, <i>BRP44L</i>, <i>PLTP</i>, <i>MGLL</i> and <i>GART</i>, compared to undifferentiated adipocyte, were significantly down-regulated with differentiated adipocyte. Correlation analysis of the detected genes and miRNAs indicated <i>BRP44L</i> may be a target of miR-103-3p and it was negatively correlated with miR-103-3p. <i>CYB5A</i> may be a target of miR-30a-5p and it was negatively correlated with miR-30a-5p. <i>SEC23A</i> may be a target of miR-19a-3p and it was negatively correlated with miR-19a-3p. <i>MGLL</i> may be a target of miR-19a-3p and it was negatively correlated with miR-19a-3p. These findings will improve more integrated information of the miRNA and genes in regulating the quantity of lipid deposition in chicken adipocyte.</p
