Hypothesis
The study investigates the effects of relaxin on cancer cell motility and tumor growth in oestrogen-independent breast cancer cells.
Conclusion
Long-term exposure to relaxin inhibits tumor growth and reduces cell motility in oestrogen-independent breast cancer cells.
Supporting Evidence
- Relaxin increased cell motility in the short term but reduced it in the long term.
- Stable MDA/RLN2 transfectants produced smaller tumors with lower S100A4 levels.
- Relaxin's effects were mediated through the down-regulation of the protein S100A4.
Takeaway
Relaxin can help slow down the growth of certain breast cancer tumors and make the cancer cells less active.
Methodology
The study used stable transfectants of MDA-MB-231 cells to assess the effects of relaxin on cell motility and tumor growth in vivo.
Limitations
The study did not observe metastasis due to the short duration of the experiment.
