Summary: Efficient delivery of miR-122 to hepatocytes using a nanomedicine-based formulation has the potential to prevent and treat colorectal cancer liver metastasis. Mechanistically, it downregulates key genes involved in metastatic and cancer inflammation pathways, increases CD8(+)/CD4(+) T-cell ratio, and decreases immunosuppressive cell infiltration, making the liver more conducive to antitumor immune response.

Summary: This study analyzed the differential expression of miRNAs between HCC patients and controls and found that miR-16 and miR-122 were significantly upregulated in early-stage HCC patients. Combining these miRNAs with AFP improved the diagnostic efficacy for HCC. Furthermore, miR-16 and miR-122 were found to regulate a number of potential target genes involved in cancer pathways.

Summary: The role of exogenous miRNAs in renal fibrosis was investigated using a mouse model. miR-122-5p was found to be downregulated in the kidneys of mice with renal fibrosis. Overexpression of miR-122-5p promoted fibrosis, while inhibition of miR-122-5p suppressed fibrosis. miR-122-5p regulated the expression of fibrosis-related mRNAs, including pro-fibrotic TGFBR2 and anti-fibrotic FOXO3.

Summary: The pathophysiology of non-alcoholic steatohepatitis (NASH) was investigated from the perspective of glycolysis and the Warburg effect, with a focus on microRNA regulation in liver-specific macrophages. The activation of glycolysis in Kupffer cells during NASH was partially induced by the upregulation of pyruvate kinase muscle 2 (PKM2) via microRNA122-5p (miR-122-5p) suppression.

Summary: The 5 ' untranslated region (UTR) of the hepatitis C virus (HCV) genome regulates virus replication and translation. Binding of miR-122 to the 5 ' UTR regulates viral replication and translation, but its precise mechanism is still unresolved. Our study shows that miR-122 binding stimulates viral translation and that enhancing translation and stabilizing the viral genome can rescue miR-122-independent HCV replication. This suggests that miR-122 plays a primary role in promoting HCV translation and genome stabilization.

Summary: This study explores a new approach for treating active tuberculosis (TB) by screening and validating microRNAs with immune-regulatory functions. The research identified differentially expressed microRNAs associated with TB and revealed their roles in regulating autophagy, apoptosis, and macrophage phagocytosis. The findings provide evidence for microRNA-based host-directed immunotherapy and offer new therapeutic targets for treatment-refractory TB.

Summary: Chronic allograft dysfunction (CAD) is a major condition affecting long-term kidney graft survival. In this study, the correlation between plasma miR-21 and the severity of CAD was investigated. RNA sequencing was performed and differentially expressed miRNAs in CAD were identified. MiR-21-5p, miR-20a-5p, and miR-101-3p were found to be associated with the TGF-beta pathway and CAD. These findings may lead to the development of early prediction miRNA biomarkers and therapeutic tools for CAD in the field of kidney transplantation.

Summary: The study investigates the regulatory functions of dopamine (DA) and its associated non-coding RNA in the metamorphosis of the cotton bollworm, Helicoverpa armigera. It is found that DA deficiency inhibits larval-pupal metamorphosis in H. armigera. The study suggests that DA pathway genes and their microRNAs could be used as a novel target for H. armigera management.

Summary: Inflammaging is a key concept in understanding how aging contributes to the development of age-related diseases, with a focus on the role of miRNAs in regulating inflammatory pathways. The assessment of individual genetic make-up alone is insufficient to depict the trajectories of age-related inflammation, and studies have shown that circulating inflammamiRs could be used to measure the degree of inflammaging.

Summary: This study examines the relationship between axon conduction and myelination in the maturing optic nerve. The results show that axon diameter, ion channel subtype, and myelin thickness are key regulators of nerve function. These findings suggest an extended period of maturation in the normal optic nerve that facilitates the development of visual signaling patterns.

Summary: By utilizing a site-specific nanovehicle, this study presents a novel approach for treating ABMR. The nanovehicle is capable of targeting the affected allograft kidney endothelium under ABMR and releasing an anti-inflammatory drug upon laser irradiation to promote endothelial recovery. This strategy holds potential for future clinical applications.

Summary: Many cardiac pathologies are associated with reduced gap junction coupling. The relationship between the phenotype and functional expression of the connexin gap junction family of proteins is controversial. Low gap junction coupling can be explained by ephaptic coupling theory and can also increase intracellular charge accumulation, resulting in faster transmembrane potential rate of change during depolarization. Studies suggest that conduction reserve is more dependent on ephaptic coupling than charge accumulation during gap junction uncoupling.

Summary: Myocardial ischemia has long-lasting negative impacts on cardiomyocyte mitochondrial ATP production. The location of damage and specific factors controlling mitochondrial function alteration following ischemia remain unclear. In this study, it was found that ischemia lowered maximal mitochondrial respiration rates, diminished the responsiveness of respiration to driving forces, and decreased the activities of every component of the oxidative phosphorylation pathway. Ischemia also led to higher ROS production. These findings highlight the importance of targeting the entire mitochondrial energy conversion cascade to improve mitochondrial function following ischemia.

Summary: Transfer RNAs (tRNAs) play a crucial role in mRNA translation by delivering amino acids to polypeptide chains. tRNAs can be cleaved by ribonucleases, resulting in tRNA-derived small RNAs (tsRNAs) with various regulatory functions. tsRNAs have been shown to have both oncogenic and tumor suppressor functions, and their abnormal expression and modifications are associated with various diseases. In this review, the biogenesis, gene regulation mechanisms, and potential therapeutic roles of tsRNAs in cancer are discussed.
