Project description:Gene expression profiles of human cell (THP-1) lines exposed to a novel Daboiatoxin (DbTx) isolated from Daboia russelli russelli, and specific cytokines and inflammatory pathways involved in acute infection caused by Burkholderia pseudomallei. Experiment Overall Design: 1. Group I:- Human monocytic macrophage (THP-1) cell lines grown in the culture medium without any bacterial infection served as untreated control group (Three Biological Replicates). Experiment Overall Design: 2. Group II:- THP-1 cells were infected with Burkholderia pseudomallei (A600 nm = OD 0.6, ~5 x 107 cfu/ml) for 24h served as a disease control group (Three Biological Replicates). Experiment Overall Design: 3. Group III:- THP-1 cells were infected with B. pseudomallei and treated with Daboiatoxin (0.5 mM) isolated from Daboia russelli russelli venom served as a treatment group (Three Biological Replicates). Experiment Overall Design: 4. Group IV:- THP-1 cells were infected with B. pseudomallei (A600 nm = OD 0.6, ~5 x 107 cfu/ml) treated with standard antimicrobial drug ceftazidime (10mg/ml) served as a drug control (Three Biological Replicates). Experiment Overall Design: 5. Group V:- THP-1 cells were exposed to Daboiatoxin (0.5 mM) without bacterial infection (Three Biological Replicates).
Project description:Burkholderia mallei and Burkholderia pseudomallei are both potential biological threats agents. Melioidosis caused by B. pseudomallei is endemic in Southeast Asia and Northern Australia, while glanders caused by B. mallei infections are rare. Here we studied the proteomes of different B. mallei and B. pseudomallei isolates to determine species specific characteristics. Analyzing the expressed proteomes of B. mallei and B. pseudomallei revealed differences between B. mallei and B. pseudomallei but also between isolates from the same species. Expression of multiple virulence factors and proteins of several PKS/NRPS clusters was demonstrated. Proteome analysis can be used not only to identify bacteria but also to characterize the expression of important factors that putatively contribute to pathogenesis of B. mallei and B. pseudomallei.
