It was estimated that probably a consistent amount (up to 6%) of the roughly estimated 35,000 mouse genes contain such functional regulatory variants[ 13].
In our data, just about 2% of human and mouse genes contain exon duplications or repeats, which are quite lower than others' work (~8% in human and ~7% in mouse) [ 20].
MyD88 is not required for the regulation of the majority of genes responsive to LPS and several MyD88-independent mouse genes contain NFκB and IFN-stimulated response element (ISRE; IFNα/β) binding sites [ 34].
The next point we addressed was the paradox that, although intron 10 of the rat and mouse genes contain mainly copies of SHORT1 including self-complementary microsatellites, the mouse has 65 miRNA-producing genes in this region, while the rat only has one gene that expresses Mir-466d.
qPCR conditions were 45 cycles as follows: 95°C for 4 s, 62°C for 10 s, and 72°C for 30 s. Normalization was done according to beta-2 microglobulin housekeeping gene (selected for its constant expression in the tissues tested), or according to a standard dilution curve on a c-fos mouse gene-containing plasmid when comparing targets amplified with different primers.
The 350-bp segment of the mouse Mcm7 gene containing the miR-25 precursor only was cloned between the XhoI and EcoRI sites of the MDH1-PGK-GFP 2.0 vector using the primers F: 5' -andCTCGAGCCCAGGACACAACCTCTGAT-3' and R: 5' -AAAGAATTCGAGGGGAATGAAGTCAAGGA-3'.
For miRNA overexpression, the 725-bp segment of the mouse Mcm7 gene containing the miR-106b, miR-93, and miR-25 precursors was cloned between the XhoI and PmeI sites of the MDH1-PGK-GFP 2.0 vector [ 105] using the primers F: 5' -AAACTCGAGCCTGCTGGCCATTCTCCGACTTTC C-3' and R: 5' -AAAGTTTAAACGGATCTTTCTTTGCTCCAGCTTCAAGC-3'.
A proximal 6 kb promoter (P6P) sequence of the mouse MyoD gene containing a proximal regulatory region (PRR) and a distal regulatory region (DRR) are sufficient to activate muscle-specific expression of MyoD in vitro and in vivo, but leaky expression in the central nervous system and delayed expression in limb buds and bronchial arches were observed [ 13, 14].
The imprinting control region within the second intron of the mouse Igf2r gene contains a CpG island comprising direct repeats, an imprinting box and the Air antisense promoter which is blocked by the methylation imprint on the active maternal allele.
The mouse TRAP gene contains multiple promoters; the most proximal to the first coding exon contains a compound start site region used selectively by macrophages and osteoclasts [27].
