KCNN4 and infection: We found that RNAi inactivation of six of eight genes encoding these proteins (clec‐190, clec‐3, dhs‐18, dhs‐2, spp‐12, spp‐9, cyp‐14A3, and cyp‐25A1) (Figure 7l, Figure S6a,b) diminished PA14 resistance of normal worms suggesting that the anti‐microbial proteins and xenobiotic‐neutralizing enzymes directed by NHR‐49 may have functional roles in defense against PA14 infection.
