Summary: Circular RNAs (circRNAs) are a group of unique non-coding RNAs generated by back-splicing, and they play critical roles in cardiovascular diseases. In this study, researchers developed a circular antisense RNA that can specifically silence the highly expressed circRNA circSlc8a1 in the mouse heart without affecting its parental linear mRNA. The findings reveal the essential role of circSlc8a1 in maintaining heart function and provide a potential gene therapy approach for cardiovascular diseases using circular antisense RNA.

Summary: RNA-binding proteins play important roles in miRNA-mediated gene silencing. This study discovered that SERBP1 is a partner protein of Argonaute2, and it participates in miR-92-mediated gene silencing by regulating the 3' UTR of KCC2. These findings advance our understanding of KCC2 translational regulation in neuronal cells and highlight the key role of SERBP1 in this gene regulation.

Summary: Recent years have seen significant progress in the use of oligonucleotide therapeutics for metabolic diseases, establishing them as a new class of drugs. There are currently five marketed oligonucleotide therapies, with many more in clinical studies, for both rare and common liver-driven metabolic diseases. Ongoing challenges and possible future developments in this field are also being discussed and explored.

Summary: Small RNAs form complexes with Argonaute proteins to repress gene expression. In the green alga Chlamydomonas reinhardtii, sRNAs contribute to the induction of photoprotection mediated by the blue-light receptor phototropin (PHOT) and the expression of LIGHT HARVESTING COMPLEX STRESS-RELATED 3 (LHCSR3). The sRNAs regulate the degree of photoprotection by controlling the expression of PHOT.

Summary: miRNAs play a key role in gene expression regulation by forming the miRNA induced silencing complex (miRISC) with Argonaute protein to target specific mRNAs. The regulation of miRISC functions in animals involves post-translational modifications, 3' UTR environment, and interactions with other proteins. Subcellular localization and vesicular trafficking also play important roles in modulating miRISC function.

Summary: Inhibition of miR-33 shifts the balance of proatherosclerotic and antiatherosclerotic immune cell subsets in atherosclerotic plaques, reducing plaque burden and inflammation. This treatment also affects the expression of specific target genes in different macrophage subsets, ultimately leading to a decrease in aortic CD8+ T cells and CD4+ T-helper 1 cells, and an increase in regulatory T cells within plaques. These findings shed light on the immune mechanisms underlying the atheroprotective effects of anti-miR-33.

Summary: The study revealed that circRNA circ_0001666 is highly expressed in pancreatic cancer tissues and cell lines, and its overexpression promotes cancer cell proliferation, EMT, and invasion, while knockdown of circ_0001666 has the opposite effects. Circ_0001666 functions as an oncogenic circRNA by sponging miR-1251 to upregulate SOX4 expression, suggesting its potential as a therapeutic target for PC.

Summary: Transitivity in plants relies on RDR6-mediated dsRNA synthesis and DCL endonuclease activity to reinforce target RNA cleavage through the formation of an RNA-induced silencing complex. This study found that the primary target site influences gene silencing and transitivity, with dsRNA synthesis generally initiated at the 3MODIFIER LETTER PRIME-end of the target RNA.

Summary: Biomolecular condensates are dynamic structures formed through various mechanisms and play crucial regulatory roles in cellular processes. RNA silencing, mediated by small RNAs, is an important gene regulatory mechanism, in which biomolecular condensates are key players. They provide spatial compartmentation for small RNA biogenesis and function, as well as modulate RNA silencing activity during stress responses.

Summary: This review discusses the challenges in studying the role and regulation of the non-coding transcriptome in cardiovascular disease, including poor annotation of the non-coding genome, determination of transcript cellular distribution, assessment of RNA processing, and identification of cell-type specific changes. It highlights similarities and differences in analyzing the non-coding and protein-coding transcriptomes, as well as the impact of lack of consensus and standardized methods on reproducibility of data.

Summary: This study provides the first phenotypic platelet characterization of healthy individuals receiving the BNT162b2 vaccine. The results show that platelet reactivity and protein expression remain unchanged after vaccination. Activation marker expression is significantly lower compared to COVID-19 patients, indicating that BNT162b2 administration does not alter platelet function.

Summary: Increased sizes and dysfunction of the left atrium have been linked to negative outcomes. Three-dimensional echocardiography is more precise than two-dimensional echocardiography in estimating left atrial volumes and ejection fraction. This systematic review and meta-analysis provide reference ranges for left atrial volumes and ejection fraction assessed by three-dimensional echocardiography in healthy adults, promoting its evaluation in everyday clinical practice.

Summary: Mass cytometry (CyTOF) is a new technology that enables high-resolution investigation of protein expression at the single cell level. This study provides a structured and reproducible method for staining platelets from platelet-rich plasma to study thrombocyte protein expression using CyTOF, allowing for sample storage and delayed measurement. The protocol also includes a bioinformatic pipeline for analyzing platelet expression, unlocking the potential of CyTOF analysis for studying platelet biology in health and disease.

Summary: Reticulated platelets (RPs) are young, hyper-reactive platelets that are larger and contain more RNA compared to older platelets. They have higher thrombogenicity and are associated with insufficient antiplatelet response to aspirin and specific P2Y(12) receptor inhibitors. RPs are promising biomarkers for the prediction of adverse cardiovascular events in cardiovascular disease.

Summary: DOT1L inhibition in VSMCs significantly reduces atherosclerosis progression by directly modulating Nf-kappa B1 and Nf-kappa B2 transcription, which are master regulators of inflammation inducing expression of CCL5 and CXCL10 cytokines, key in atherosclerosis development. DOT1L could be a promising therapeutic target for vascular diseases as its inhibition reduces plaque progression.

Summary: This study analyzed real-world data of diabetic patients using SGLT2 inhibitors and found that these drugs were well tolerated and led to improved glycemic control and weight loss after one year of treatment. The increase in hematocrit was more significant in high cardiovascular risk patients, indicating a potential cardioprotective mechanism mediated by these compounds through euvolemic restoration.
