• First in the World: ITMO Researchers Train DNA Constructs to Detect Cancer Cells Based on Cancer Marker Concentration

  Researchers from ITMO University have developed DNA constructs based on antisense oligonucleotides that can detect different cancer marker concentrations in cells. Thanks to this capability, the DNA constructs activate only in cancer cells with high concentrations of cancer markers, cleaving the RNAs of genes responsible for the cells’ viability. At the same time, healthy cells, even with several copies of cancer markers inside, remain untouched. With this solution, target cancer therapy will become more accurate, efficient, and safe. The new DNA constructs were described in a paper published in Chemical Communications.

• ITMO Scientists Suggest Novel Nanoparticle-Based Cancer Treatment

  Cancer is the second most common death cause in the world, which in 2020 took the lives of nearly 10 million people – every sixth death, according to WHO. Globally, researchers are developing new, more efficient treatments for oncological diseases. Scientists from ITMO also contribute to these efforts: recently, they have come up with a universally applicable magnetic particle from zinc ferrite and manganese ferrite that can facilitate both cancer diagnostics and treatment. The new method increases the efficiency of radiotherapy by 40%, and during magnetic hyperthermia it can heat cancer cells in several seconds, while also securing less exposure for the healthy cells. This study was published in Journal of Materials Chemistry B.

• Scientists Propose New Nanoparticles That Can Potentially Be Used to Treat Cancer with Magnetic Fluid Hyperthermia

  A group of Russian scientists have synthesized manganese–zinc ferrite nanoparticles that can potentially be used in cancer treatment. Due to their unique magnetic properties, the particles can serve as deactivators of affected cells while having almost no negative impact on healthy tissues. The results have been published in the Journal of Sol-Gel Science and Technology.
