Cloned beta cells of a diabetic patient

Having transplanted genetic material from skin cells of a patient with type I diabetes into someone else's egg, scientists obtained a culture of embryonic cells, which were then "re-educated" into insulin cells of the pancreas.

Pancreatic cancer drug ready for clinical trials

Pancreatic cancer cells develop resistance to the traditionally used doxorubicin especially quickly. A drug that suppresses the synthesis of proteins that provide this resistance significantly increases the effect of treatment.

Alzheimer's disease: a dangerous mistake

Although the chaperone Hsp90 prefers already folded proteins, it nevertheless binds to the tau protein. An international team of scientists has deciphered the mechanisms of this process and offers a new target for the treatment of Alzheimer's disease.

The voice of the crying in the desert

An open letter from the Society of Scientists to the Prime Minister in support of the development of genetic engineering in Russia was initiated by a group of biologists concerned about the campaign against GMOs. You can also put your signature.

An important step to victory over atherosclerosis

An experimental drug that blocks the synthesis of one of the lipids of the cell wall normalizes all stages of cholesterol metabolism and prevents the development of atherosclerosis even in the presence of a pronounced predisposition.

"Stealth nanoparticles" for cancer diagnosis and drug delivery

Scientists have synthesized nanoparticles that are similar in structure to viruses. Such objects are "invisible" to the immune system and in the future may be useful in the diagnosis of cancer and the treatment of a number of diseases.

Another role of sirtuin-1

The SIRT1 protein is necessary during cell reprogramming to lengthen and preserve telomeres. In addition, sirtuin-1 guarantees the integrity of the genome of induced pluripotent stem cells.

The eighth formula of light

For the first time in the last 25 years, scientists from Moscow and Krasnoyarsk have deciphered the structure of a new luciferin, a key component of a new ATP-dependent bioluminescent system. This is now the eighth luciferin known to science.

Nanoclay instead of catgut

Applying an aqueous solution of nanoparticles to the edges of deep wounds of the skin and internal organs provides almost instantaneous "gluing" of damage, stopping bleeding and rapid wound healing without visible scar.

For the first time: therapeutic cloning of adult cells

For the first time, scientists were able to apply the method of transferring somatic cell nuclei (therapeutic cloning) to adult cells and grow stem cells close to embryonic cells that are genetically identical to DNA donors.

Regenerative Medicine: from here to infinity

Today, regenerative medicine is able to grow an organ in the laboratory for transplantation to a patient. Previously, it was possible to do this with the trachea, urethra and bladder, and recently the vagina and nose have been added to this list. What's next?
