The RNA World: the first step

A group of scientists from the University of Manchester (England) managed to synthesize a ribonucleotide (a compound necessary for the formation of RNA) in external conditions comparable to the conditions of the primitive Earth, and on the basis of molecules that were most likely in the primary broth.

The heart helps to restore blood vessels

In response to damage to the vessel wall, smooth muscle cells move from a state of "resting phenotype", in which they are only able to contract, to a state of "synthesis phenotype", when they begin to proliferate. The FHL2 protein synthesized by heart cells suppresses the activity of genes necessary for the preservation of smooth muscle cells of blood vessels in a state of "rest".

Cancer diagnosis and treatment: "4-in-1" nanoparticles

The researchers connected fluorescent dye, RNA fragments and peptide fragments to iron oxide nanoparticles. The task of peptides is to identify tumor cells, RNA fragments suppress the work of a number of genes characteristic of cancer cells, killing them. Magnetic iron oxide nanoparticles play the role of contrast for MRI, and fluorescent dye allows you to observe cancer cells using microscopy.

Increased life expectancy: poorly digested food is better than a low-calorie diet

A good substitute for a low-calorie diet has been found, contributing to an increase in life expectancy in the simplest organisms. Yeast cells grown on a glycerin diet live twice as long as yeast grown in a conventional low-calorie environment. In addition, such yeast is more resistant to damaging environmental factors.

Genes playing a role in breast cancer metastasis have been found

New York researchers have identified three genes that specifically regulate the spread of breast cancer metastases to the brain. The data obtained are important for understanding the mechanisms of metastasis spread and developing possible approaches to cancer treatment, especially gene therapy methods.

Oral delivery system of small interfering RNAs

Scientists from the University of Massachusetts have developed a new – oral – method of targeted delivery of small interfering RNAs (miRNAs). The method was tested on mice and showed excellent results in suppressing the inflammatory process, similar to what develops in humans with a number of diseases.

Smart sensor: the laboratory in the tube will help with injuries and concussions

The fruit of the joint efforts of neurosurgeons and nanotechnology engineers is a new generation catheter that combines familiar functions and a set of microsensors that read physiological indicators. Such a microlaboratory will allow real-time monitoring of changes in the condition of patients who have suffered a concussion or other brain injury.
