Regulation of fatty acid synthase on tumor and progress in the development of related therapies

引用

中华医学杂志(英文版) 2024年第16期137卷 1894-1902页

作者： Bai Rilan Cui Jiuwei Cancer Center the First Hospital of Jilin University Changchun Jilin China

Fatty acid synthase (FASN) is an essential molecule in lipid metabolic pathways, which are crucial for cancer-related studies. Recent studies have focused on a comprehensive understanding of the novel and important regulatory effects of FASN on malignant biological behavior and immune-cell infiltration, which are closely related to tumor occurrence and development, immune escape, and immune response. FASN-targeting antitumor treatment strategies are being developed. Therefore, in this review, we focused on the effects of FASN on tumor and immune-cell infiltration and reviewed the progress of related antitumor therapy development.
