Figure Lengend Snippet: Self-self hybridization at 56°C of 5 μ g (per dye) of labeled total mouse brain RNA. Diagrams of average intensity values show filtered results in logarithmic scale. The y axis represents values of AlexaFluor3 dye measurement at 532 nm, and the x axis represents values of AlexaFluor5 dye measurement at 635 nm. Red spots represent all signals from LNA and DNA probes spotted on the microarray slide. (a, c) Detection of MiR-9 (yellow spots, black arrow) and miR-9* (yellow spots, white arrow) with LNA probes. (b, d) Detection of snoRNAs (yellow spots) with antisense DNA probes (including mismatch probes in (d)). Sense DNA probes signals were below detection levels and thus filtered out. (a, b) RNA labeling using the protocol described by manufacturer. (c, d) Modified RNA labeling (see ).

Figure Lengend Snippet: Self-self hybridization at 56°C of 1 μ g (per dye) of labeled total mouse brain RNA. Diagrams of average intensity values show filtered results in logarithmic scale. The y axis represents values of AlexaFluor 3 dye measurement at 532 nm, and the x axis represents values of AlexaFluor5 dye measurement at 635 nm. Red spots represent all signals from LNA and DNA probes spotted on the microarray slide. Detection of (a) tRNAs (yellow spots) and (b) 7SK RNA (yellow spots) with antisense DNA probes (including mismatch and deletion probes). Sense DNA probes were below detection levels and thus filtered out. (c) Diagram showing mean intensity values ( y axis) of DNA probes for detection of highly structured ncRNAs.

Figure Lengend Snippet: (a) Heat map showing differential expression between brain and mouse embryonic stem cells of ncRNAs spotted on the DNA-LNA microarray. Up- and downregulation of ncRNAs in brain are indicated with red or green color, respectively. Only differential expression of at least two folds is indicated. (b) Northern blot showing expression of SNORD55 and SNORA71 in mouse embryonic stem cells and mouse brain. Ten micrograms of total RNA were used, and 5.8S rRNA was used as a loading control.

Figure Lengend Snippet: Real-time PCR verification of differential expression of selected ncRNAs captured by DNA and LNA probes on the DNA/LNA microarray platform. Results are represented as relative expression levels between mouse ES cells and mouse brain. Data are shown as mean ± SEM; n = 5; * P < 0.05; ** P < 0.01, *** P < 0.005 significantly different from mES cells by Student t -test.
