RNA base editing relies on the introduction of adenosine-to-inosine changes into target RNAs in a highly programmable manner in order to repair disease-causing mutations. Here, we propose that RNA base editing could be broadly applied to perturb protein function by removal of regulatory phosphorylation and acetylation sites. We demonstrate the feasibility on more than 70 sites in various signaling proteins and identify key determinants for high editing efficiency and potent down-stream effects. For the JAK/STAT pathway, we demonstrate both, negative and positive regulation. To achieve high editing efficiency over a broad codon scope, we applied an improved version of the SNAP-ADAR tool. The transient nature of RNA base editing enables the comparably fast (hours to days), dose-dependent (thus partial) and reversible manipulation of regulatory sites, which is a key advantage over DNA (base) editing approaches. In summary, PTM interference might become a valuable field of application of RNA base editing. RNA base editing enables a precise, reversible and doseable change of genetic information. Here, authors propose base editing as a method to control post-translational modifications via removal of regulatory phosphorylation and acetylation sites, applying the approach to modulation of the JAK/STAT pathway via editing of wildtype alleles.

The world witnessed and went through the COVID-19 pandemic for a major part of two years, the after effects of which still reverberate loudly worldwide. The psychological and emotional turmoil was felt by everyone but was accentuated many fold, especially for the COVID-19 survivors. Years of research have already established gratitude and hope to be the predictors of psychological well-being. The present research study made an attempt to explore gratitude and hope as the correlates of psychological well-being amongst COVID-19 survivors. The sample of this research study consisted of 76 survivors (N=76) from the state of Haryana, India. Gratitude Questionnaire-6 by McCullough et al. (2002); the Adult State Hope Scale by Snyder et al. (1996); and Ryff's Psychological Well-being Scale (RPWBS-18; Ryff et al., 2010) were used for the assessment of the variables. Descriptive statistics and Pearson's Product Moment Correlation was applied to explore the relationship among the variables. The findings of the study establish a significant positive correlation between both, gratitude and psychological well-being & hope and psychological well-being. [ABSTRACT FROM AUTHOR]
