05.05.2014Having 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.
30.04.2014Pancreatic 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.
30.04.2014The epidermis (the top layer of the skin), grown from induced pluripotent human stem cells, can replace laboratory animals when testing medicines and cosmetics.
29.04.2014A chip with a protein applied to it, with which botulinum toxin interacts, allows you to detect the presence of even very low concentrations of poison in the blood for not four days, as now, but five hours.
29.04.2014There are many theories of aging, and all specialists dealing with this problem feel the need for an integral approach, the need for a common concept that would unite different theories.
28.04.2014Although 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.
28.04.2014A cocktail of eight transcription factors ensures stable reprogramming of myeloid and lymphoid cells into full-fledged hematopoietic (hematopoietic) stem cells.
28.04.2014Scientists from the University of Calgary have uncovered the mechanism of stimulating the growth of damaged neuron processes and confirmed the possibility of its use as a means to restore nerve connections after injury.
25.04.2014An 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.
25.04.2014An 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.
25.04.2014A new gene therapy approach restores memory in a mouse model of early-stage Alzheimer's disease by activating Crtc1 protein synthesis.
25.04.2014Scientists 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.
24.04.2014The 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.
24.04.2014The results of genome-wide DNA sequencing showed that at the end of life, almost all leukocytes circulating in the body of a 115-year-old long-lived woman were descendants of only two related hematopoietic stem cells.
24.04.2014Pavel Borodin, a Russian geneticist, head of the laboratory at the Novosibirsk Institute of Cytology and Genetics SB RAS, studies the behavior of chromosomes of various animals, and in his spare time shamelessly exploits cats to promote modern biology.
23.04.2014For 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.
23.04.2014Applying 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.
22.04.2014For 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.
22.04.2014Today, 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?
