3T3-L1 Preadipocytes were maintained in growth medium (Undifferentiated), or induced for adipocyte differentiation in the absence (Differentiated control) or presence of various concentrations of 1 or rosiglitazone.
When first considering the differentiated control, mRNA levels of Cebpβ and Cebpδ both increased after day 1, followed by an increased expression of Srebf1a.
However, 804 genes were differentially expressed between terminally differentiated control and Dali knockdown cells, of which 376 genes (46.8%) also differed in expression between Dali knockdown and control cells prior to their differentiation.
Cell viability of differentiated control or HD model striatal neurons was examined using the MTS assay, which reflects the number of viable cells [19].
Although differentiated control cells demonstrate a significant degree of nuclear translocation of unphosphorylated β-catenin, HPRT-knockdown cells reproducibly are markedly deficient in nuclear translocation.
A slight increase was observed for both Cebpβ and Rxrα expression in response to both BDE-47 and TROG compared to differentiated control at day 2. Expression of Cebpβ was significantly higher for BDE-47 than the differentiated control at this time point, while the expression of Rxrα was significantly higher for TROG.
Levels of BMP-2 secretion in cells treated with p55-gag were significantly lower than undifferentiated control at day 3 (p ≤ 0.05, n = 3), and significantly lower than levels of the differentiated control at days 9 and 15 (p ≤ 0.01 and p ≤ 0.05 respectively, n = 4).
After neural induction, Oct4/ATSCs differentiated into neural cells expressed higher levels of TuJ than in differentiated control ATSCs (Fig. 7A).
Treatment with p55-gag significantly reduced the degree of calcium deposition relative to differentiated control, while REV increased it (p ≤ 0.05 relative to differentiated control, n = 6); with increases of 82.4% ± 10% and 430 ± 71% relative to untreated control respectively (p ≤ 0.001, n = 6).
