Figures & Tables

Fig. 1

Sequence analyses of OaCdc42. A. The full-length cDNA and deduced amino acid sequences of OaCdc42. GenBank accession number for OaCdc42 cDNA was KC425615. The conserved domain (CD) was in the frame. Double asterisks (∗∗) represent stop codon (TGA). Primers for 3′-, 5′-RACE are marked with underlined arrows. “S” in bold and italics indicates the predicted phosphorylated sites. Residue numbers of secondary structure are coloured per domain as in panel. B. The three-dimensional structure of OaCdc42. Each of α- helices and β-sheet is indicated by a different colour

Multiple alignments of Cdc42 between sheep and other species. The amino acid sequence of OaCdc42 is underlined. (∗) – 100% identical; (:) – highly conserved; (.) – semi-conserved

Phylogenetic analysis of Cdc42 from sheep compared with other species. The phylogenetic tree was constructed by MAGA5.1 software using neighbour-joining (NJ) method. The numbers on the nodes reveal percentage frequencies in 1,000 bootstrap replications. The scale bar indicates 0.005 substitutions per site

Tissue distribution of OaCdc42 mRNA from healthy sheep. The relative value of OaCdc42 mRNA was calculated using 2-ΔΔCt method and β-actin as the reference gene. Data were presented as mean ±SD (n = 3, ∗ P < 0.05; ∗∗ P < 0.01 vs. buffy coat). Error bars showed the SD. All tests were performed in triplicate

The differential expression of OaCdc42 mRNA between Bm-infected sheep and S2-vaccinated sheep. Relative value of OaCdc42 mRNA was calculated using 2-ΔΔCt method and β-actin as the reference gene. Data were presented as mean ±SD (n = 9, ∗P < 0.05; ∗∗P < 0.01). Error bars showed the SD. All tests were performed in triplicate
