How gene expression is kept in check and the implications for cancer

DNA helix

Cancers are alive¬†in a sense, they are similar to a parasite and they fight to stay alive when we just want them gone. Cancers have access to¬†complex ways of avoiding elimination and because we cannot easily do anything to treat it short of surgery or chemotherapy, we regularly lose to some of the more cunning types. Now researchers have learned how living beings can keep gene expression in check — this might partly explain the uncontrolled gene expression found in many forms of cancer.

Classical Music modulates genes responsible for brain functions

Although listening to music is common in all societies, the biological determinants of listening to music are largely unknown. According to a latest study, listening to classical music enhanced the activity of genes involved in dopamine secretion and transport, synaptic neurotransmission, learning and memory, and down-regulated the genes mediating neurodegeneration. Several of the up-regulated genes were known to be responsible for song learning and singing in songbirds, suggesting a common evolutionary background of sound perception across species.
