Many people use melatonin supplements as a sleep aid. But if you’ve ever felt as if they aren’t helping, you’re not alone.

Dr. Gabriella Gobbi, at McGill Faculty of Medicine and Health Sciences, is doing research on how the brain responds to melatonin.

At the center of this complex system are two receptors. Think of them as “locks” that melatonin, the “key,” binds to in order to affect different levels of sleep. Melatonin can activate both receptors, sometimes cancelling out the intended effects.

Dr. Gobbi is working on targeted therapies on single receptors to open doors for more effective sleep therapy and pain regulation.

Today is World Ovarian Cancer Day 💙, a day to honour loved ones lost, support those currently fighting and push forward in the search for a cure.

More than 3,000 Canadians are diagnosed with ovarian cancer each year, a disease that is often difficult to detect early and challenging to treat. Each year, the London Run for Ovarian Cancer brings our community together to raise vital funds for ovarian cancer research. Funds raised help scientists understand the biology of ovarian cancer, build better models to study it and test new ideas that could one day lead to earlier diagnosis and more effective therapies.

Without generous community support, much of this work simply would not be possible. Donate to ovarian cancer research today: https://bit.ly/49vFTmL
