Summary: The PTEN tumor suppressor gene is frequently mutated in tumors and in cancer predisposition patients or those with macrocephaly associated with autism. A study has analyzed PTEN nonsense mutations and set standards for the potential restoration of full-length PTEN proteins from mutated PTEN genes through translational readthrough. The findings indicate that prevalent pathogenic PTEN mutations can be functionally restored through readthrough-inducing compounds, offering potential for precision interventions in specific patient groups.

Summary: This study shows that self-cleavage of the glmS ribozyme riboswitch can occur during transcription before the ribozyme is fully synthesized. Co-transcriptional folding of the RNA allows the ribozyme catalytic core to react without the downstream stability domain. Slow sequential folding promotes the formation of the native core structure. Ribozyme self-cleavage at an early stage of transcription is important for the regulation of glmS in B. subtilis.

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.

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.

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.

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.

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.

Summary: Starting from a list of nine dysregulated miRNAs in early-stage CRC patients, the study verified the therapeutic effects of anti-miRNA PNAs targeting the most relevant up-regulated miRNAs. PNAs down-regulated these target miRNAs and induced apoptosis in CRC cellular models. Combining anti-miRNA PNAs with pro-apoptotic compounds like sulforaphane resulted in high levels of apoptosis induction.

Summary: The human homologue of mouse Ly-1 antibody reactive clone protein (LYAR) is a potential regulator of gamma-globin gene transcription. The LYAR rs368698783 (G > A) polymorphism is present in beta-thalassemia patients and reduces the LYAR binding efficiency to the A gamma-globin gene. This study aimed to stratify beta-thalassemia patients based on the rs368698783 (G > A) polymorphism and investigate their erythroid precursor cells' response to selected HbF inducers in vitro.

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.
