Summary: Genome editing is crucial for functional genomics, but the challenge lies in the prevalence of error-prone non-homologous end joining. This study compared the efficacy of various genome editing systems on murine zygotes, finding that homologous recombination with ssDNA template following Cas9 cleavage guided by sgRNA remains the optimal method for precise genome alterations in animals.

Summary: This study demonstrates that a 4-miRNA cassette can reprogram vascular smooth muscle cells into endothelial cells, and these induced cells exhibit high similarity to native endothelial cells. Injected induced cells even restore blood flow faster than conventional endothelial cells in a mouse model, suggesting the potential of this approach for vascular disease therapy.

Summary: This study investigated the effect of graphene oxide (GO) complexed with antisense miRNA-21 on cytokine expression levels in U87, U118, U251, and T98 glioma cell lines. The results showed that GO-antisense miRNA-21 complexes significantly regulated the expression levels of TIMP-2, IL-6, IL-8, ICAM-1, and MCP-1 compared to electroporation of antisense miRNA-21. Furthermore, GO-mediated antisense miRNA-21 transfection resulted in upregulation of TIMP-2 and downregulation of ICAM-1, as well as significant decrease in IL-8 expression level compared to electroporation.

Summary: Cancer-derived sEVs can be used as a drug delivery system that targets cancer cells due to their unique features. However, the oncogenic cargo within them limits their application. We proposed an electroporation-based strategy to extract the endogenous cargo from cancer-derived sEVs, and used membrane fusion to fuse them with liposomes to form hybrid particles. These engineered hybrid particles showed improved targeting ability and higher drug loading ability, and demonstrated enhanced treatment efficiency.

Summary: Peptides composed of a short chain of amino acids play important roles in plant growth, development, and stress responses, derived from precursor proteins or small open reading frames. They act as local signal molecules for intercellular communication and ligands for cellular signaling transduction. Recent studies have shown that non-coding RNAs can also encode peptides, such as miRNA-encoded peptides (miPEPs), which can increase the expression of corresponding miRNAs by enhancing MIRNA gene transcription.

Summary: The Cre-loxP recombination system is a powerful tool for genome engineering, with one application being the induction of Cre recombination in genetic mouse models. A technique of delivering Cre protein into mouse zygotes by electroporation is described as simple, affordable, and highly efficient, resulting in faster generation of desired models. Additionally, it is shown that the method is suitable for allelic conversion in primary cells derived from conditional mouse models.

Summary: In this study, the mechanism of antitumor activity of bovine pancreatic RNase A was extensively investigated. The results showed that RNase A can penetrate into cells and reduce the synthesis of RNA, leading to decreased invasion and migration of tumor cells. RNase A also disrupted the favorable tumor microenvironment by altering gene expression near metastatic foci. Bioinformatic analysis revealed the main processes modulated by RNase A in the tumor microenvironment.

Summary: miRNAs in plants play a crucial role in controlling growth, development, and stress tolerance by modulating the expression of target genes. Modulating the expression of specific stress/development-related genes can be achieved by targeting the corresponding miRNAs. Understanding the molecular mechanism of miRNA biogenesis, particularly the processing of pri-MIRNAs, is essential for effectively modulating miRNA expression levels and ultimately improving plant yield and stress tolerance.

Summary: In this study, a flexible organic electronic ion pump was developed for controlled delivery of phytohormones in plant vascular tissue, which can induce long distance plant responses. The system provides a new tool for the study and engineering of stress-tolerant plants. The results showed that the delivery of ABA triggered stomata closure far away from the delivery point, indicating systemic vascular transport of the delivered ABA.

Summary: miRNAs are small non-coding RNA molecules that control gene expression by translational inhibition and mRNA destabilization, playing crucial roles in hematopoiesis. Recent studies have also confirmed the significant roles of miRNAs in cell processes such as the cell cycle, apoptosis, and differentiation, although the main contributions of some miRNAs remain unclear. Future research is needed to focus on miRNA activities during various hematopoietic stages and hematological malignancies.

Summary: Adult stem cells, particularly neural stem cells (NSCs), show decreased differentiation potential with aging during long-term in vitro culture. However, introducing four reprogramming factors can inhibit NSC aging by decreasing the expression of inflammatory and ER stress-related genes. This rejuvenation method could enhance the potential of NSCs for neurological disease treatment.

Summary: Forced differentiation of mouse embryonal stem cells into lymphatic endothelial cells (LECs) using PLGA nanospheres with growth factors significantly improves yield of LYVE1(+) LECs. Enhanced LEC differentiation with VEGF-A/C-conjugated PLGA nanospheres is mediated by increased expression of genes important for lymphatic vessel formation, providing a platform for mechanistic study of LEC development in mammals.

Summary: This study analyzed the phenotypes of Dgcr8 conditional knockout mice in the female reproductive tract, revealing distinct reproductive defects in Dgcr8(td/td) mice. The deficiency of Dgcr8 with different Cre systems induced overlapping but distinct phenotypes and altered the profiles of microRNAs and their target mRNAs, highlighting the importance of selecting appropriate Cre drivers for gene investigation.

Summary: Kefir, a fermented milk product, is associated with reduced cancer incidence and has chemo-sensitizing effects on drug-resistant colorectal cancer cells. It attenuates multidrug resistance, increases intracellular accumulation of ROS and chemotherapeutic agents, decreases ABC transporters, and modulates upstream regulators such as ERK 1/2, JNK, and NF-kappa B. This suggests that kefir consumption may improve the effectiveness of chemotherapy in cancer patients.

Summary: This study reveals the function of the ATP-dependent chromatin remodeler Ino80 in the cell cycle regulation of embryonic stem cells (ESCs). Loss of Ino80 leads to an extended cell cycle phase and cell apoptosis. Furthermore, the regulatory mechanism of Ino80 differs slightly in differentiating ESCs. This research demonstrates that Ino80 regulates the cell cycle of ESCs through transcriptional regulation, and its function may be universal to other cell types.

Summary: The miR-252-5p-Rab6 regulatory axis controls the Notch signaling pathway in Drosophila wing development. The loss of miR-252 increases wing size, while its overexpression leads to patterning defects in adult wings. The overexpression-induced wing phenotypes are caused by aberrant Notch signaling and intracellular accumulation of full-length Notch receptor, possibly due to defects in intracellular trafficking and autophagy-mediated degradation.

Summary: The overexpression of Drosophila miR-263b in the fat body leads to a decrease in larval fat body size, resulting in severe growth defects accompanied by reduced cell proliferation and cell size. Additionally, a significant portion of larval fat body cells disassociate prematurely. This study also suggests that miR-263b-5p suppresses the expression of Laminin A (LanA), a key component of basement membranes. Overall, the findings indicate a potential role for miR-263b in developmental growth and cell association by regulating LanA expression in the Drosophila fat body.
