Scientists have grown a model of the human brain "in vitro"

Or rather, she grew up by herself: the stem cells self-organized into a brain "organoid" the size of a peanut grain. This is an incredibly valuable model for studying developmental pathologies and neurodegenerative diseases.

The two - faced MC1R gene

A mutation in the MC1R gene determines the presence of red hair and fair skin in a person and, as it turned out, on the one hand, it reduces the risk of prostate cancer and increases the likelihood of skin cancer – melanoma.

Damaged, sick and old muscles will be restored by Pax7

Understanding how the Pax7 protein works will help make satellite cells as active as possible. This may lead to a revolution in the treatment of muscular dystrophy and, perhaps, will preserve muscle strength in old age.

A new approach to protecting the skin from aging

It was found that it is possible to reduce the intensity of age-related skin changes and improve wound healing processes by inhibiting the activity of the enzyme 11beta-HSD1.

Cancer node

The activity of cancer mRNAs depends on the mutual work of two proteins that untangle loops and knots on the regulatory site of such mRNAs and enable the ribosome to begin synthesis of the cancer protein on it.

The cause of pain is not inflammation, but bacteria

Scientists have revised the view of the source of pain in infectious tissue damage. Pain neurons are affected not by inflammation, but by multiplying bacteria. In addition, it turned out that pain does not stimulate, but suppresses the immune response.

Aging by inheritance

Scientists have shown for the first time that the aging process occurs not only as a result of the accumulation of mutations in mitochondrial DNA during life. Mutations inherited from the mother can accelerate the aging process.
