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：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-时间依赖性。此外PTL通过抑制VEGF、MTA1、TGF-β1的表达显著抑制宫颈癌细胞的迁移。

Our research results demonstrate that PTL significantly inhibits the proliferation of cervical cancer cells HeLa and SiHa in a concentration- and time-dependent manner. Additionally, PTL significantly suppresses the migration of cervical cancer cells by inhibiting the expression of VEGF, MTA1, and TGF-β1.
