Effect of jiedu huayu recipe containing serum on the expressions of survivin and NF-kappaB of K562/A02 cell apoptosis by / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of Jiedu Huayu Recipe containing serum on the expressions of survivin gene of leukemia K562/A02 cell apoptosis and the expression of nuclear factor kappa B (NF-kappaB).</p><p><b>METHODS</b>K562/A02 cells were divided into six groups. An equal volume of calf serum, rabbit serum, high, middle, and low dose Jiedu Huayu Recipe containing serum, and interferon was respectively added. K562 sensitive cell strain was set up as the control. The expressions of survivin in K562/A02 cells after treated with Jiedu Huayu Recipe containing serum were detected using semi-quantitative reverse transcriptase polymerase chain reaction method. The expressions of NF-kappaB/P65, NF-kappaB/P50, and IKBa were detected using Westem blot method.</p><p><b>RESULTS</b>The survivin resistant gene was highly expressed in K562/A02 cells. After treated by Jiedu Huayu Recipe containing serum, the expressions of survivin could be obviously lowered in the high and middle dose Jiedu Huayu Recipe containing serum groups as well as the interferon control group. NF-kappaB was also highly expressed in K562/A02 resistant cells. After treated by Jiedu Huayu Recipe containing serum, the expressions of P65, P50, and IkappaBalpha decreased to some degrees. The decrement was the most obvious in the middle and high dose Jiedu Huayu Recipe containing serum groups. The decreased expressions of P65 and P50 in the high dose Jiedu Huayu Recipe containing serum group were higher than that in the interferon control group (P<0.05). The decrement of IkappaBalpha was equivalent to that of the interferon control group (P>0.05).</p><p><b>CONCLUSION</b>Jiedu Huayu Recipe could block the NF-kappaB signal pathway of K562/A02 cells and reverse drug resistance by influencing the expression of NF-kappaB-survivin genes.</p>
