RNAi effectively reduces the expression of exogenous CYP17 in HeLa cells by up to 50%. The CYP17 mRNA and androstenedione production of theca cells are slightly, but not significantly, reduced when compared with non-specific siRNA |

three CYP17-targeting lentivirus shRNAs, targeting different sites of CYP17, are constructed and synthesized, that all have a silencing effect on CYP17 mRNA and protein, which leads to a decline of all the levels of androstenedione, 17-hydroxyprogesterone and testosterone to a certain degree, but progesterone levels decline significantly |

the expression level of CYP17A1 in adrenals is regulated by ACTH and by gonadotropic hormone in the testis and ovaries. At least three factors, NF1, SF1 and SF3, control the expression level of human CYP17A1 in adrenals. Regions of the CYP17A1 gene responsible for binding transcriptional factors are: nt -107 to -85 and nt -178 to -152 for NF1-1C, nt -227 to -184 for SF1 and SF3 |

p450c17 expression and ratio of lyase to hydroxylase is high in preparatory and pre-spawning phases of ovary and low in spawning phase. Expression of p450c17 correlates well with testicular recrudescence with maximum expression in preparatory and spawning phases. Neither protein expression nor lyase/hydroxylase activity change significantly during hCG-induced oocyte maturation, while in vitro and in vivo though mRNA levels increase |
