This study aims to evaluate the potency of ethanol extract of red okra pods (EEROP) in inhibiting growth of cervical cancer cells through repression of the cell cycle-associated oncogenes. The EEROP treatment was given to HeLa cells cultured with RPMI medium and incubated at 37°C with 5% CO. The MTT method was used to measure HeLa cell growth and IC values. The mRNA levels of the three cell cycle-associated oncogenes (, , and ) were evaluated by qRT-PCR to determine the effect of EEROP treatment on the cell cycle. The lowest percentage of viable cells at 24, 48, and 72 hours after EEROP treatment was in the dose of 1000 g/mL with a growth percentage of 71.60% at 24 hours, 55.61% at 48 hours, and 46.97% at 72 hours. The IC values were 2845, 1153, and 776.8 g/mL for 24, 48, and 72 hours, respectively. The three oncogenes at a dose of 1000 g/mL significantly decreased the lowest mRNA levels compared to other doses with oncogene that experienced the greatest decrease. The mRNA level of dose 1000 g/mL EEROP at the oncogene was 0.014-fold changes, at the oncogene was 0.097-fold changes, and at the oncogene was 0.028-fold changes. The EEROP has been shown to decrease the expression of three cell cycle-associated oncogenes. This is also supported by the growth of HeLa cells that did not increase throughout 24, 48, and 72 hours. However, further research is needed on the main active components in red okra that function as anticancer, so that in the future, okra can not only stop cancer cell growth but also induce cancer cell death.
本研究旨在通过抑制细胞周期相关癌基因来评估红秋葵荚乙醇提取物(EEROP)对宫颈癌细胞生长的抑制效力。将EEROP处理给予用RPMI培养基培养并在37°C、5% CO₂条件下孵育的HeLa细胞。采用MTT法测量HeLa细胞生长及IC值。通过qRT-PCR评估三种细胞周期相关癌基因( 、 和 )的mRNA水平,以确定EEROP处理对细胞周期的影响。EEROP处理后24、48和72小时,活细胞百分比最低的是1000 g/mL剂量组,24小时时生长百分比为71.60%,48小时时为55.61%,72小时时为46.97%。24、48和72小时的IC值分别为2845、1153和776.8 g/mL。与其他剂量相比,1000 g/mL剂量的三种癌基因显著降低至最低mRNA水平,其中 癌基因下降幅度最大。1000 g/mL EEROP剂量组在 癌基因处的mRNA水平变化为0.014倍,在 癌基因处为0.097倍,在 癌基因处为0.028倍。已证明EEROP可降低三种细胞周期相关癌基因的表达。HeLa细胞在24、48和72小时内生长未增加也支持了这一点。然而,需要对红秋葵中发挥抗癌作用的主要活性成分进行进一步研究,以便未来秋葵不仅能阻止癌细胞生长,还能诱导癌细胞死亡。
