Transcriptome analysis of FMF-04-159-2 treated MDA-MB-231 cells

Wnt/ß-catenin signaling pathway has become a key signaling pathway regulating mammary organogenesis and oncogenesis. However, the therapeutic methods by targeting Wnt pathway against breast cancer has been limited. To address this challenge, we investigated the function of cyclin-dependent kinase 14 (CDK14), a member of Wnt signaling pathway, in mammary development and breast cancer progression. We showed that CDK14 was expressed in the mammary basal layer and elevated in triple negative breast cancer (TNBC). CDK14 knockdown reduces colony formation ability and regeneration capacity of mammary basal cells, and significantly inhibits murine MMTV-Wnt-1 basal-like mammary tumor progression. Excitingly, knockdown of CDK14 or pharmacological inhibition of CDK14 by FMF-04-159-2 significantly inhibited the progression and metastasis of human TNBC. Mechanistically, CDK14 inhibition inhibits mammary regeneration and TNBC progression by attenuating Wnt/ß-catenin signaling. Together, we demonstrated that CDK14 regulates mammary regeneration and breast tumorigenesis, and is a promising therapeutic target for TNBC.
