In addition, SW480 and HCT116 cells were treated with deoxycholic acid for 15, 30, 45, 60, 90 and 120 minutes. It was found that the deoxycholic acid treated cells showed an elevation of ATP activity by 12.35 %, 20.08 %, 29.69 %, 33.56 %, 45.85 %, 54.32 %, respectively. While the HCT116 treated cells, showed an elevation of ATP activity by 3.69 %, 5.59 %, 8.52 %, 12.26 %, 16.52 %, 19.71%, respectively.From the experiments conducted using the cell lines described above, it was further confirmed that genes CYP7A1 (cytochrome P450, family 7, subfamily A, polypeptide 1), AKR1D1 (aldo-keto reductase family 1, member D1), ALDH1A1 (aldehyde dehydrogenase 1 family, member A1), BAAT (bile acid Coenzyme A: amino acid N-acyltransferase), ABCA1 (ATP-binding cassette, sub-family A, member 1), APOC3 (apolipoprotein C-III), LIPA, LIPE (lipase, hormone-sensitive), PTGER2 (prostaglandin E receptor 2) and PTGS2 (prostaglandin-endoperoxide synthase 2) were up-regulated.

Pyridoxine, pyridoxal , pyridoxamine as well as their phosphated forms are structural analogues in which pyridoxal-5"-phosphate and pyridoxamine-5"- phosphate are the biological active forms in vivo which act as the cofactors of aminotransferases, amino acid decarboxylases, cysteine desufbrase and cystathionine , etc by constant transconversions. Recently, it was discovered that B6 played a novel role in tumor growth suppression.

它包括三种结构十分近似的化合物：吡哆醇(Pyidoxine，PN)、吡哆醛(Pyridoxal，PL)和吡哆胺(Pyridoxamine，PM)，分别以磷酸化的形式发挥作用，其中吡哆醛-5'-磷酸(Pyridoxal-5'-phosphate，PLP)为B_6在体内的活性形式，通过与磷酸吡哆胺(Pyidoxamine-5-phosphate，PMP)的互变，作为多种酶(氨基转移酶、氨基酸脱羧酶、半胱氨酸脱硫酶、胱硫醚酶等)的辅酶而发挥传递基团的作用。

The synergism ratios of piperonyl butoxide to alpha-cypermethrin in these three strains were similar(about 20-fold), which suggested metabolic detoxification probably confers about 20-fold inherent resistance in the B-type whitefly, as PBO is a mixed function oxygenase and esterase inhibitor and glutathione S-transferase is not affinity to resistance in B. tabaci. The synergism ratio of triphenyl phosphate to alpha-cypermethrin in the NJ strain was 12-fold, which implied the synergism of PBO in the B-type whitefly is mainly due to inhibiting esterase activity.

增效试验表明PBO对这三个品系的增效作用均为20倍左右，因为在烟粉虱中PBO即是多功能氧化酶抑制剂，也是酯酶抑制剂，而谷胱甘肽S-转移酶与抗性无关，因此推断代谢酶在B型烟粉虱对高效氯氰菊酯的抗性发展中起到的相对作用可能为20倍左右，而且这种抗性是B型烟粉虱天生的；TPP对NJ品系的增效作用为12倍，说明PBO增效作用主要是由于抑制酯酶而引起的，即代谢抗性大部分由酯酶所贡献。
