Article Title: Arxes: retrotransposed genes required for adipogenesis
doi: 10.1093/nar/gkq1289
Figure Lengend Snippet: Silencing of the Arxes abrogates adipogenesis, while Spcs3 knockdown does not change adipogenic marker gene expression. 3T3-L1 cells were transduced with silencing constructs (siArxes or siSpcs3) or nontargeting control (ntc), and induced to undergo adipogenesis with standard DMI treatment unless indicated otherwise. ( A ) qPCR mRNA measurement shows that Arxes knockdown using the siArxes silencing constructs is specific to the Arxes, while Spcs3 expression is not reduced. Data are presented as mean ± SEM from three independent transduction experiments. ( B ) Lipid droplets were visualized by oil red O staining of 7 days differentiated 3T3-L1 cells. Lower panel of the oil red O staining shows a partial rescue of the differentiation deficiency if 1 µM rosiglitazone is present during differentiation procedure. ( C ) Expression of marker genes of adipogenesis was measured with qPCR on Day 7 of adipogenesis in Arxes-silenced and control cells. Data are presented as mean ± SEM from three independent transduction experiments. ( D ) qPCR mRNA measurement shows that Spcs3 knockdown using the siSpcs3 silencing construct is specific to the Spcs3 while Arxes mRNA is not reduced. Data are presented as mean ± SEM from two independent transduction experiments. ( E ) Spcs3 knockdown does not influence adipogenic marker gene expression as measured with qPCR on Day 7 in DMI induced cells. Data are presented as mean ± SEM from two independent transduction experiments.
