Description
Acquired antimalarial drug resistance produces treatment failures and has led to periods of global disease resurgence. In P. falciparum, resistance is known to arise through genome-level changes such as mutations and gene duplications. We now report an epigenetic resistance mechanism involving genes responsible for the plasmodial surface anion channel, a nutrient channel that also transports ions and antimalarial compounds at the host erythrocyte membrane. Two blasticidin S-resistant lines exhibited markedly reduced expression of clag Mutant FCB-br1 and wild-type FCB samples were hybridized to seven arrays (biological repeats) using forward (n=2) and reverse (n=5) fluoro.
