Summary: The long non-coding RNA UCC acts as a competing endogenous RNA of miR-143-3p and upregulates SOX5 by absorbing miR-143-3p, resulting in proliferation and migration of non-small-cell lung cancer (NSCLC) cells both in vitro and in vivo. UCC enhances carcinogenesis of NSCLC cells via the miR-143-3p/SOX5 axis, which may function as a novel target for NSCLC treatment.

Summary: A circular RNA, circANKRD17, is found to function as a key regulator in promoting glycolysis in breast cancer cells, leading to cell growth, migration, invasion, and cell-cycle progression. CircANKRD17 acts as a sponge for miR-143, relieving the suppressive effect of miR-143 on hexokinase 2 and enhancing glycolysis in breast cancer cells.

Summary: In this study, the researchers investigated the function of cyclin-dependent kinase 14 (CDK14) in mammary development and breast cancer progression. The results showed that CDK14 is expressed in mammary basal cells and elevated in triple negative breast cancer (TNBC). CDK14 knockdown or inhibition was found to suppress mammary regeneration and the progression of TNBC.

Summary: LncRNA SOX2-OT is highly expressed in HCC cells and tissues, with poor prognosis in patients. Inhibiting SOX2-OT decreased malignant behaviors of HCC cells and promoted MSI2 expression by binding to miR-143-3p. Nude mouse tumorigenesis experiments confirmed the role of SOX2-OT in promoting proliferation and invasion of HCC cells.

Summary: Our study revealed that circRASSF2 regulates BC progression through the miR-1205/HOXA1 pathway. High expression of circRASSF2 is associated with distant metastasis, lymph node metastasis, TNM stage, differentiation, and tumor size in BC patients, leading to inferior overall survival (OS) and progression-free survival (PFS). This indicates the potential of circRASSF2 as a therapeutic target for treating BC patients.

Summary: The invasion of nerves by cancer cells, or perineural invasion (PNI), is influenced by the nerve microenvironment and is associated with negative clinical outcomes. However, the specific characteristics of cancer cells that enable PNI have not been well defined. Through serial passaging of pancreatic cancer cells in a murine sciatic nerve model of PNI, we generated cell lines enriched for a rapid neuroinvasive phenotype. These leading neuroinvasive cells exhibited upregulation of proteins involving the plasma membrane, cell leading edge, and cell movement. They also underwent phenotypic changes from a mesenchymal to an amoeboid phenotype, and acquired increased migration ability and affinity for dorsal root ganglia. Inhibition of ROCK reversed these changes and reduced PNI in a murine sciatic nerve model. This study highlights the plasticity of cancer migration mode in facilitating rapid nerve invasion.

Summary: In this study, the gene expression of enzymes secreted by Malassezia globosa in the skin was investigated using targeted RNA sequencing. The study found that the expression of these enzymes is regulated by the fungus's environment and differs significantly from healthy skin sites. Additionally, a pseudoprotease MGL_3331 was identified to elicit an immune reaction in patients with atopic dermatitis. This highlights the importance of studying fungal proteins in physiologically relevant environments and their role in host immunity.

Summary: Mini zinc fingers play important roles in plant development, including control of cell division and expansion, meristem state transition, and growth and organ development. They have diverse modes of action, such as direct gene activation, interaction with specific transcription factors, and aggregation of protein complexes for chromatin remodeling. Further research is needed to explore their wider range of biological functions and their involvement in biotic and abiotic stress responses.

Summary: This study found that infection with the causative bacteria of edwardsiellosis, Edwardsiella tarda NUF251, leads to the production of superoxide radicals, causing oxidative stress. The research on the Jfsod1 gene suggests that the transcription factor NF-IL6 plays a significant role in upregulating the transcriptional activity of the gene in response to oxidative stress induced by NUF251 infection.

Summary: The importance of F337 in TcGlcK was investigated using the hole mutagenesis approach, revealing its key interactions with aromatic tail groups in inhibitor molecules. Mutants retaining activity and structural similarity were obtained, suggesting the possibility of TcHxK existing as a monomer lacking the F337 residue. Similar D-glucosamine inhibitors may bind less strongly to TcHxK due to the absence of van der Waals contacts from residue side chains.

Summary: Ribonucleases play a crucial role in RNA regulation by processing, degrading, and quality controlling cellular transcripts. Campylobacter jejuni, the main cause of human gastroenteritis, relies on the exoribonuclease PNPase (CjPNP) for low-temperature survival, virulence factor synthesis, and swimming, cell adhesion/invasion, and chick colonization abilities. The crystallographic structure of CjPNP, along with SAXS analysis, confirms its trimeric arrangement and provides insight into domain arrangement and flexibility. Mutations in highly conserved residues reveal unexpected RNA degradation activity even under conditions favoring polymerization. These findings have significant implications for the development of strategies to combat C. jejuni infections.

Summary: Evidence suggests that activating nicotinic acetylcholine receptors (nAChRs) can reduce cardiac injury caused by ischemia and reperfusion. In this study, the expression of a4, a6, and a132 nAChR subunits in the rat heart's left ventricle was demonstrated. The nAChR agonists cytisine and varenicline, commonly used for nicotine addiction treatment, were found to significantly reduce myocardial ischemia-reperfusion injury, with varenicline showing greater protection. The presence of a4132, a7, and/or a6132-containing receptors suggests that the protective effect of varenicline may be mediated by these subunits. These findings indicate a potential new use for cytisine and varenicline as cardioprotective agents.

Summary: Changes to our environment have led to the emergence of human pathogens such as chikungunya virus, which is now a major public health concern. In this study, the interconnection between skeletal muscle cells metabolism, their differentiation stage, and the infectivity of chikungunya virus was investigated. The results showed that chikungunya virus infectivity is dependent on cell differentiation and metabolism and that the virus interferes with cellular metabolism.
