Abstract

Purpose

We previously demonstrated that progesterone (P4) interacted with folic acid (FA) and abolished the FA-reduced endothelial cell proliferation and migration. These findings led us to investigate whether FA can interfere with the P4-promoted breast cancer cell proliferation and migration.

Methods

We conducted MTT and wound healing assay to evaluate cell proliferation and migration, respectively. Western blot analysis and immunoprecipitation were performed to examine the protein expression and protein–protein interaction, respectively.

Results

We demonstrated that P4 promoted proliferation and migration of breast cancer cell lines (T47D, MCF-7, BT474, and BT483). However, co-treatment with P4 and FA together abolished these promotion effects. Treatment with P4 alone increased the formation of PR-cSrc complex and the phosphorylation of cSrc at tyrosine 416 (Tyr416). However, co-treatment with P4 and FA together increased the formations of cSrc-p140Cap, cSrc-Csk, and cSrc-p-Csk complex, and the phosphorylation of cSrc at tyrosine 527 (Tyr527). Co-treatment with P4 and FA together also abolished the activation of cSrc-mediated signaling pathways involved in the P4-promoted breast cancer cell proliferation and migration.

Conclusions

Co-treatment with FA and P4 together abolished the P4-promoted breast cancer cell proliferation and migration through decreasing the formation of PR-cSrc complex and increasing the formations of cSrc-p140Cap and cSrc-Csk complex, subsequently activating Csk, which in turn suppressed the phosphorylation of cSrc at Tyr416 and increased the phosphorylation of cSrc at Tyr527, hence inactivating the cSrc-mediated signaling pathways. The findings from this study might provide a new strategy for preventing the P4-promoted breast cancer progress.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
