Animal study shows depriving deadly brain cancer of cholesterol kills tumour cells.

Adult brain cancers are almost always universally fatal, due in part to the biochemical composition of the central nervous system and the blood-brain barrier, which selectively and protectively limits the … Continue Reading Animal study shows depriving deadly brain cancer of cholesterol kills tumour cells.

Neuroimaging shows that astrocytes are responsible for joining the 2 halves of the brain together.

A significant milestone in the evolution of the mammalian brain is the emergence of the corpus callosum, which is exclusively present in placental mammals.  This commissure forms the largest axon … Continue Reading Neuroimaging shows that astrocytes are responsible for joining the 2 halves of the brain together.

Researchers identify the key instigator of neuron damage in sporadic and inherited ALS.

The onset of ALS, also known as Lou Gehrig’s disease, is marked by the gradual degradation and eventual death of neuronal axons, the slender projections on nerve cells which transmit … Continue Reading Researchers identify the key instigator of neuron damage in sporadic and inherited ALS.

Trauma’s inherited epigenetic fingerprint observed in children of Holocaust survivors.

The children of traumatized people have long been known to be at increased risk for post-traumatic stress disorder (PTSD). However, there are very few opportunities to examine biologic alterations in … Continue Reading Trauma’s inherited epigenetic fingerprint observed in children of Holocaust survivors.

Researchers image the epigenetics of the human brain for the first time ever.

Epigenetic dysfunction is implicated in many neurological and psychiatric diseases, including Alzheimer’s disease and schizophrenia. Consequently, histone deacetylases (HDACs) are being aggressively pursued as therapeutic targets. However, a fundamental knowledge … Continue Reading Researchers image the epigenetics of the human brain for the first time ever.

Human study shows ‘aggressive drunk’ gene may protect carriers from obesity and associated risks.

It is known that genetics plays a role in obesity, with genes directly causing obesity in disorders such as Bardet-Biedl syndrome and Prader-Willi syndrome. However, genes and behaviour may both … Continue Reading Human study shows ‘aggressive drunk’ gene may protect carriers from obesity and associated risks.
