Quantification of expression of genes by controls and E₂-treated Pb01 cells during M-to-Y transition.

<p>Panel A illustrates <i>hsp90</i>, B; <i>hsp70</i>, C; <i>hsp40</i>, D; hydrophobin, E; <i>Y20</i>, F; chitin synthase, G; <i>gfa1</i>, H; <i>gls1</i>, I; <i>mok11</i>, J; GTPase RhoA, K; phosphatidylinositol 4-kinase, L; <i>cdr4</i>, M; <i>ubr11</i>, and N; retropepsin. The expression value of each gene was obtained from β-tubulin-normalized quantitative real-time PCR (qRT-PCR), plotting controls (C; untreated plus ethanol-treated control) vs E₂-treated at different time points. The measured quantity of each Pb01 gene from each sample was normalized by using C_T values obtained for the β-tubulin qRT-PCR on the same plate. The relative quantification of each gene and β-tubulin gene expression was determined by a standard curve (i.e. C_T values plotted against logarithm of the DNA copy number). The values represent the number of copies of the cDNA of each gene divided by the number of copies of the cDNA of the β-tubulin gene. The data represent the mean (±SEM) of triplicate of qRT-PCR runs from RNA samples of two independent biological replicates used in the microarray hybridization. Statistical comparison between C (controls) and E₂ (E₂-treated) samples was done at each time point and significant differences denoted on the figure above the bars by one or more asterisks, which indicate the p value (* p<0.05, ** p<0.01, *** p<0.001). The box on the right side of each figure shows the result of statistical comparison between C (controls) or E₂ (E₂-treated) samples at various time points and the 0 h baseline time point.</p
