请帮我把这句中文翻译成英文我需要翻译结果学术一些符合论文投稿风格请充分思考并尽可能准确地了解我的要求。我想翻译的句子是：小白菊内酯parthenolidePTL一种从中药小白菊的叶子中提取得到的倍半萜烯内酯类天然产物表现出良好的抗肿瘤活性然而PTL对宫颈癌的作用及分子机制尚不清楚。我们的研究结果显示PTL能明显抑制宫颈癌细胞HeLa和SiHa的增殖且呈浓度和时间依赖性。此外PTL通过抑制VEGF、

Parthenolide (PTL), a sesquiterpene lactone natural product extracted from the leaves of traditional Chinese herb feverfew, exhibits promising anti-tumor activity. However, the effect and molecular mechanism of PTL on cervical cancer remain unclear. Our research results show that PTL can significantly inhibit the proliferation of cervical cancer cells HeLa and SiHa in a concentration- and time-dependent manner. In addition, PTL significantly inhibits the migration of cervical cancer cells by suppressing the expression of VEGF, MTA1, and TGF-β1
