Inhibitory Effect of Phosphorothioate Oligonucleotide Complementary to G6PD mRNA on Murine Melanoma.

In terms of the incidence among all tumors, skin cancer is on top, with the most deadly among them being melanoma. The search for new therapeutic agents to combat melanoma is very relevant. In our opinion, antisense oligonucleotides (ASO) aimed at suppressing the genes responsible for their viability in cancer cells give hope for treatment, which makes it possible to eliminate cancer cells near the tumor site both before and after surgery.

Oligonucleotide Insecticides for Green Agriculture: Regulatory Role of Contact DNA in Plant-Insect Interactions.

Insects vastly outnumber us in terms of species and total biomass, and are among the most efficient and voracious consumers of plants on the planet. As a result, to preserve crops, one of the primary tasks in agriculture has always been the need to control and reduce the number of insect pests. The current use of chemical insecticides leads to the accumulation of xenobiotics in ecosystems and a decreased number of species in those ecosystems, including insects.

Immunohistochemical Expression of VDR in Myocardium: Postmortem Evaluation of COVID-19 Patients.

Morphological data on heart damage and its mechanisms due to extremely severe course of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection are limited, as well as data on the correlation of damage and expression of vitamin D receptors (VDRs). In this study, we analyzed a series of myocardial samples obtained during postmortem autopsy of 48 critically ill patients with COVID-19 who died with SARS-CoV-2-associated pneumonia. The purpose of the study was to evaluate immunohistochemical VDR expression in the myocardium.
