Epitranscriptomics of Ischemic Heart Disease-The IHD-EPITRAN Study Design and Objectives.

Epitranscriptomic modifications in RNA can dramatically alter the way our genetic code is deciphered. Cells utilize these modifications not only to maintain physiological processes, but also to respond to extracellular cues and various stressors. Most often, adenosine residues in RNA are targeted, and result in modifications including methylation and deamination.

Discovery of Small Molecules that Activate RNA Methylation through Cooperative Binding to the METTL3-14-WTAP Complex Active Site.

Chemical modifications of RNA provide an additional, epitranscriptomic, level of control over cellular functions. N-6-methylated adenosines (m6As) are found in several types of RNA, and their amounts are regulated by methyltransferases and demethylases. One of the most important enzymes catalyzing generation of m6A on mRNA is the trimer N-6-methyltransferase METTL3-14-WTAP complex.

The prevalence and correlates of anticoagulant rodenticide exposure in non-target predators and scavengers in Finland.

The most common rodent control method worldwide is anticoagulant rodenticides (ARs), which cause death by internal bleeding. ARs can transfer to non-target predators via secondary exposure, i.e.

Fusarium mycotoxin enniatin B: Cytotoxic effects and changes in gene expression profile.

The mycotoxin enniatin B, a cyclic hexadepsipeptide produced by the plant pathogen Fusarium, is prevalent in grains and grain-based products in different geographical areas. Although enniatins have not been associated with toxic outbreaks, they have caused toxicity in vitro in several cell lines. In this study, the cytotoxic effects of enniatin B were assessed in relation to cellular energy metabolism, cell proliferation, and the induction of apoptosis in Balb 3T3 and HepG2 cells.

SERT and NET polymorphisms, temperament and antidepressant response.

Background: The genetic variations in norepinephrine transporter (NET) and serotonin transporter (SERT) genes have been associated with personality traits, several psychiatric disorders and the efficacy of antidepressant treatment.

Aims: We investigated the separate effects and possible interactions between NET T-182C (rs2242446) and SERT 5-HTTLPR (rs4795541) polymorphisms on selective serotonin reuptake inhibitors (SSRI) treatment response and temperamental traits assessed by the Temperament and Character Inventory (TCI) in a clinical sample of subjects with major depressive disorder (MDD).

Methods: Our sample of 97 patients with major depression completed the 107-item TCI temperament questionnaire (version IX) at the initial assessment of the study and after 6 weeks of follow-up.
