“Metformin enhances anti-cancer properties of resveratrol in MCF-7 breast cancer cells…” (2023)

The essence of the research

This study examined the effects of Metformin (a blood sugar lowering drug) and Resveratrol (a natural substance) on MCF-7 breast cancer cells, including their use in combination with the chemotherapy drug cisplatin.

Main experimental results

1. Effects of each substance

Metformin

Inhibits the growth of cancer cells

Causes cells to “stop their life cycle” at the G0/G1 stage.

Increases ROS (oxidative stress)

But it does not induce apoptosis (programmed death).

Resveratrol

Reduce the growth of cancer cells

Stimulates apoptosis (cell death)

This causes cell cycle arrest as well.

2. Effects when used together

Using Metformin + Resveratrol

Synergize each other in inhibiting cancer cells

Makes it possible to stop the cell cycle even more.

3. Best results (using 3 items together)

Metformin + Resveratrol + Cisplatin

Has the "strongest" anti-cancer effect

Stimulates several mechanisms simultaneously:

Apoptosis (cell death)

Autophagy (self-degradation of cells)

Cell cycle arrest (stops division)

Important mechanism discovered

Metformin → stimulates AMPK → inhibits mTOR → reduces cell division.

Resveratrol → increases ROS → stimulates apoptosis

When used together → a synergistic effect occurs, causing more cancer cell killing.

Conclusion of the research

Both Metformin and Resveratrol have anti-cancer effects.

Using them together increases efficiency.

And when used in conjunction with chemotherapy → helps increase treatment results.

The researchers suggest that this approach could be used as "adjuvant therapy" in the future.

Brief summary

Metformin = stops division

Resveratrol = stimulates cell death

Used together = better at killing cancer cells.

Used together with chemotherapy = most effective.
