(Thio)xanthone derivatives induce the expression of czt-1 and of different members of the ABC transporter family. (A) The levels of expression (in FPKMs) of NCU09974 (czt-1) in N. crassa cells treated with TX34, XP13 (or DMSO) are presented. (B) The levels of expression (in FPKMs) of NCU09830 (atrb), NCU05591 (cdr4), NCU07546, NCU09975 (abc-3) and NCU04161 in N. crassa cells treated with the (thio)xanthone derivatives were obtained and the fold change versus the control (DMSO) was calculated. *, P-value < 0.05.
