Nonsense mutations generate in-frame stop codons in mRNA leading to a premature arrest of translation. Functional consequences of premature termination codons (PTCs) include the synthesis of truncated proteins with loss of protein function causing severe inherited or acquired diseases. A therapeutic approach has been recently developed that is based on the use of chemical agents with the ability to suppress PTCs (read-through) restoring the synthesis of a functional full-length protein. Research interest for compounds able to induce read-through requires an efficient high throughput large scale screening system. We present a rapid, sensitive and quantitative method based on a dual-fluorescence reporter expressed in the yeast Saccharomyces cerevisiae to monitor and quantitate read-through at PTCs. We have shown that our novel system works equally well in detecting read-through at all three PTCs UGA, UAG and UAA.

Comprehensive Characterization of an Off/On Rhodol-Based Lysosomal Tracker for Orthogonal Cellular Analysis by Confocal Imaging

Carolina Chieffo, Emiliano Altamura, Layth Ben Trad, Guillaume Pilet, Ofelia Maniti, Thierry Granjon, Saida Mebarek, Peter Strazewski, Michele Fiore

Summary: Two highly fluorescent xanthene-cyanamide lysosomal trackers emitting at similar wavelengths were synthesized from fluorescein and rhodol methyl esters using microwave-assisted reactions. The on and off forms of these trackers were extensively characterized using various analytical techniques. Unlike rhodamine-type dyes, the ring-opened forms of fluorescein- and rhodol-cyanamides exhibited stability in protic solvents under circumneutral and basic pH conditions. Confocal imaging of osteoblastic cells using an orthogonal combination of fluorescent dyes allowed for the differentiation of various organelles and nuclei.

SARS-CoV-2 viral entry and replication is impaired in Cystic Fibrosis airways due to ACE2 downregulation

Valentino Bezzerri, Valentina Gentili, Martina Api, Alessia Finotti, Chiara Papi, Anna Tamanini, Christian Boni, Elena Baldisseri, Debora Olioso, Martina Duca, Erika Tedesco, Sara Leo, Monica Borgatti, Sonia Volpi, Paolo Pinton, Giulio Cabrini, Roberto Gambari, Francesco Blasi, Giuseppe Lippi, Alessandro Rimessi, Roberta Rizzo, Marco Cipolli

Summary: As an inherited disorder characterized by severe pulmonary disease, cystic fibrosis could be considered a comorbidity for coronavirus disease 2019. However, current clinical evidence suggests that cystic fibrosis may actually protect against SARS-CoV-2 infection. The expression of SARS-CoV-2 receptors in primary airway epithelial cells is regulated by the CFTR channel, and dysfunctional CFTR channels in cystic fibrosis cells result in reduced viral entry and replication.

Summary: Cystic fibrosis transmembrane conductance regulator (CFTR) modulators have provided a significant therapeutic advantage for people with cystic fibrosis (pwCF). However, these modulators face limitations in reducing chronic lung bacterial infection and inflammation, which are the main causes of respiratory damage and insufficiency in pwCF, especially in adults. This article revisits the debated issues of pulmonary bacterial infection and inflammatory processes in pwCF, highlighting the mechanisms favoring bacterial infection, the interplay between Pseudomonas aeruginosa and Staphylococcus aureus, and the cross-talk among bacteria, bronchial epithelial cells, and host immune defenses. The recent findings on the effect of CFTR modulators on bacterial infection and inflammation are also presented to identify potential therapeutic targets for respiratory pathology in pwCF.

Summary: The objective of this study was to develop an experimental model system for studying the reduction of toxic alpha-globin aggregates in beta-thalassemia. K562 cellular clones were produced that stably produced high levels of alpha-globin protein and showed increased apoptosis and autophagy. This model system can be used to screen pharmacological agents that activate autophagy and reduce alpha-globin accumulation, as well as for new therapeutic approaches targeting the reduction of alpha-globin gene expression.

Light energy transduction in liposome-based artificial cells

Paola Albanese, Fabio Mavelli, Emiliano Altamura

Summary: In this work, we review the latest strategies for assembling energetically autonomous artificial cells that can convert light energy into chemical energy and support internal metabolic pathways. The artificial cells are inspired by photosynthetic machineries found in nature and are either directly reconstituted in the membrane of artificial compartments or encapsulated in organelle-like structures. We report recent examples based on liposome technology and multi-compartment architectures, highlighting their importance in the field of artificial cell synthesis research, as well as discussing some limitations and future perspectives of the bottom-up approach.

The Cystic Fibrosis Transmembrane Conductance Regulator Gene (CFTR) Is under Post-Transcriptional Control of microRNAs: Analysis of the Effects of agomiRNAs Mimicking miR-145-5p, miR-101-3p, and miR-335-5p

Chiara Papi, Jessica Gasparello, Matteo Zurlo, Lucia Carmela Cosenza, Roberto Gambari, Alessia Finotti

Summary: This study aims to investigate the effects of molecules mimicking the activity of pre-miR-145-5p, pre-miR-335-5p, and pre-miR-101-3p on Calu-3 cells and discuss their potential applications in pre-clinical studies. The results show that treatment with agomiR-145-5p effectively inhibits CFTR gene expression and protein production. Therefore, agomiR pre-miR-145-5p should be considered as a therapeutic option for inhibiting CFTR gene expression in various pathological conditions.

Cationic Calix[4]arene Vectors to Efficiently Deliver AntimiRNA Peptide Nucleic Acids (PNAs) and miRNA Mimics

Jessica Gasparello, Chiara Papi, Matteo Zurlo, Stefano Volpi, Roberto Gambari, Roberto Corradini, Alessandro Casnati, Francesco Sansone, Alessia Finotti

Summary: One of the most promising approaches for gene regulation is the microRNA therapeutic method, which focuses on controlling the activity of microRNAs (miRNAs) that are dysregulated in diseases such as cancer. This can be achieved by inhibiting overexpressed miRNAs or restoring downregulated miRNAs using miRNA-mimics. The development of efficient and targeted vectors for delivering these molecules is a crucial topic in pharmacological modulation of miRNAs.

Effects of Sirolimus Treatment on Fetal Hemoglobin Production and Response to SARS-CoV-2 Vaccination: A Case Report Study

Maria Rita Gamberini, Cristina Zuccato, Matteo Zurlo, Lucia Carmela Cosenza, Alessia Finotti, Roberto Gambari

Summary: In this study, a representative clinical case showed that sirolimus monotherapy in fi-thalassemia patients induced an increase in fetal hemoglobin but did not prevent the production of anti-SARS-CoV-2 IgG. Further studies are needed to confirm the safety and potential positive effects of sirolimus on the humoral response to anti-SARS-CoV-2 vaccination in fi-thalassemia patients. This study may also be of interest to a broader population receiving sirolimus treatment for various pathologies.
