The Progress of Immune Cells-induced Inflammatory Response in Gout.

Gout, based on hyperuricemia, is an immune disease characterized by redness and pain caused by monosodium urate (MSU) deposition in the joints. Inflammation is the fundamental cause of gout symptoms, and many immune cells, such as monocytes/macrophages, neutrophils, and T lymphocytes, have been shown to be involved in various processes of pathological progress. This study reviews the changes and functions of different immune cells during the occurrence and development of gout, focusing on the mechanisms and signaling pathways by which macrophages activate nod-like receptor pyrin-containing 3 (NLRP3) inflammasome to initiate gout inflammation in order to further elucidate the pathogenesis of gout and provide new targets for the research of anti-gout drugs.

Consistent RNA expression and RNA modification patterns in cardiotoxicity induced by Matrine and Evodiamine.

Recent research has demonstrated the efficacy of traditional Chinese medicine (TCM) and its active compounds in combating cancer, leading to an increasing utilization of TCM as adjunctive therapy in clinical oncology. However, the optimal dosage of TCM remains unclear, and excessive use may result in cardiotoxicity, which poses a significant health concern for patients undergoing systemic treatment. Therefore, elucidating the underlying mechanisms of cytotoxicity induced by TCM can provide valuable insights for clinical management.

Neurons are the primary cells responsible for information processing in the central nervous system (CNS). However, they are vulnerable to damage and insult in a variety of neurological disorders. As the most abundant glial cells in the brain, astrocytes provide crucial support to neurons and participate in synapse formation, synaptic transmission, neurotransmitter recycling, regulation of metabolic processes, and the maintenance of the blood-brain barrier integrity.

Trifarotene alleviates skin photoaging injury by inhibition of JNK/c-Jun/MMPs.

Long-term exposure to ultraviolet (UV) radiation induces skin photoaging, which manifests as oxidative stress, inflammation, and collagen degradation. Multiple approaches (topical or systemic retinoids, antioxidants, alpha-hydroxy acids, laser, surgery) are used in the treatment of photoaged skin, and the use of topical retinoids is currently a primary clinical treatment. Previous studies revealed that retinoic acid promotes keratinocyte proliferation and reduces melanin deposition and matrix metalloproteinase (MMP) secretion; it also causes potential allergic and inflammatory damage to the skin.

Research progress on prediction of RNA-protein binding sites in the past five years.

Accurately predicting RNA-protein binding sites is essential to gain a deeper comprehension of the protein-RNA interactions and their regulatory mechanisms, which are fundamental in gene expression and regulation. However, conventional biological approaches to detect these sites are often costly and time-consuming. In contrast, computational methods for predicting RNA protein binding sites are both cost-effective and expeditious.

Progress of Ferroptosis in Ischemic Stroke and Therapeutic Targets.

Ferroptosis is an iron-dependent form of programmed cell death (PCD) and ischemic stroke (IS) has been confirmed to be closely related to ferroptosis. The mechanisms of ferroptosis were summarized into three interrelated aspects: iron metabolism, lipid peroxide metabolism, as well as glutathione and amino acid metabolism. What's more, the causal relationship between ferroptosis and IS has been elucidated by several processes.

Stage-specific regulation of undifferentiated spermatogonia by AKT1S1-mediated AKT-mTORC1 signaling during mouse spermatogenesis.

Undifferentiated spermatogonia are composed of a heterogeneous cell population including spermatogonial stem cells (SSCs). Molecular mechanisms underlying the regulation of various spermatogonial cohorts during their self-renewal and differentiation are largely unclear. Here we show that AKT1S1, an AKT substrate and inhibitor of mTORC1, regulates the homeostasis of undifferentiated spermatogonia.
