We can – and indeed, we should – use our own right to free speech to challenge expression we think is unpleasant or wrong.
Nevertheless, differential processing of stem-loop precursors, small RNA duplexes, and, in general, miRNA biochemical properties challenge expression analysis methods usually used to analyze mRNAs.
We therefore challenged their expression in patient samples and also explored iASPP inhibition in colorectal cancer cells by introduction of exogenous miRNA expression.
After OVA challenge, expression of IL-23R mRNA was greatly increased (Fig. 1B).
Effects of immune challenge expression of several genes involved in immune response, cuticular hydrocarbon biosynthesis, and the Notch signaling pathway were confirmed using quantitative real-time PCR.
As shown in Figure 3A, at 12 hours after LPS challenge, expression of TNF-α in cardiomyocytes was elevated in the 10 ng/mL LPS group compared to controls, and 0.02 μM DOB further increased LPS-induced TNF-α expression in cardiomyocytes.
At 2 hrs after E. coli challenge, expression of 83 genes was modulated by treatment (70 up- and 13 down-regulated); at 8 hrs, 193 (110 genes up- and 83 down-regulated); and at 24 hrs, 256 (113 up- and 142 down-regulated).
Following E. coli immune challenge, expression of Attacin-A, Attacin-C, and Diptericin-A was significantly reduced in the absence of Akirin or a functional Brahma complex, when compared to Attacin-D, Cecropin-A2, Cecropin-B, and Pirk or control (RNAi-GFP, Fig 6D I, Supplementary Fig S11C and D).
(CM) can hardly be challenged: Meaningful expressions have semantic correctness conditions.
Exposure to IL-1 and TNFα in vitro significantly upregulated TRPV1 expression in challenged cartilage (average relative expression 3.34 (95% CI 2.55 to 4.37) versus 1 (95% CI 0.68 to 1.48) (n=4) (figure 2A).
