AI Article Synopsis

  • The discovery of a guanine quadruplex in the TMPRSS2 mRNA could lead to innovative anticancer and antiviral treatments, as TMPRSS2 is linked to both cancer and respiratory viral infections like SARS-CoV-2.
  • TMPRSS2 facilitates virus entry into cells by aiding membrane fusion through its proteolytic activity, making it a significant target for therapeutic strategies.
  • An experimental-computational approach has resolved the first atomic-level structure of the guanine quadruplex in TMPRSS2 RNA, revealing a rigid core and flexible loop, crucial for developing targeted ligands.

Article Abstract

The presence of a guanine quadruplex in the opening reading frame of the messenger RNA coding for the transmembrane serine protease 2 (TMPRSS2) may pave the way to original anticancer and host-oriented antiviral strategy. Indeed, TMPRSS2 in addition to being overexpressed in different cancer types, is also related to the infection of respiratory viruses, including SARS-CoV-2, by promoting the cellular and viral membrane fusion through its proteolytic activity. The design of selective ligands targeting TMPRSS2 messenger RNA requires a detailed knowledge, at atomic level, of its structure. Therefore, we have used an original experimental-computational protocol to predict the first resolved structure of the parallel guanine quadruplex secondary structure in the RNA of TMPRSS2, which shows a rigid core flanked by a flexible loop. This represents the first atomic scale structure of the guanine quadruplex structure present in TMPRSS2 messenger RNA.

Lead (Pb) ions give an imminent danger since they have been known to cause persistent damage to humans, plants, and animals, even at low concentrations, and cysteine (Cys) elevated levels are critical indicators for many diseases. Therefore, their detection is critical in pharmaceutical and environmental samples. This study tailored an innovative fluorescence switch off-on assay to detect Pb and Cys based on the amplification of G-quadruplex (G-4) to N-methylmesoporphyrin IX (NMM).

G-quadruplexes (G4s) are distinctive four-stranded nucleic acid structures formed by guanine-rich sequences, making them attractive targets for drug repurposing efforts. Modulating their stability and function holds promise for treating diseases like cancer. To identify potential drug candidates capable of interacting with these complex DNA formations, docking studies and molecular dynamics (MDs) simulations were conducted.

There is compelling evidence that the absorption of low-energy UV radiation directly by DNA in solution generates guanine radicals with quantum yields that are strongly dependent on the secondary structure. Key players in this unexpected phenomenon are the photo-induced charge transfer () states, in which an electric charge has been transferred from one nucleobase to another. The present work examines the factors affecting the population of these states during electronic relaxation.

The "secondhit" pathway is responsible for biallelic inactivation of many tumor suppressors, where a pathogenic germline allele is joined by somatic mutation of the remaining functional allele. The mechanisms are unresolved, but the human PKD1 tumor suppressor is a good experimental model for identifying the molecular determinants. Inactivation of PKD1 results in autosomal dominant polycystic kidney disease, a very common disorder characterized by the accumulation of fluid-filled cysts and end-stage renal disease.

Iron homeostasis is strictly related to numerous physiological pathways including cell cycle progression and cell growth. The newest anticancer strategies focus on either depleting the cells with a suitable chelator or increasing their loading by administering iron complexes to induce ferroptosis. Iron depletion inhibits cell proliferation, while iron overload induces the damage of guanine nucleobases in G-quadruplex structures via ROS generation, leading to genome instability.
