The circadian clock generates ~24-hour rhythms that anticipate daily environmental changes. Circadian clock and glucose metabolism are tightly interconnected, and both are disrupted in aging and disease. To examine how glucose hypometabolism impacts circadian rhythm, we downregulated glycolytic enzymes - - (-), (), and () - in clock cells.

Background: Despite the potential cognitive benefits of ginseng, evidence of its effects on cognitive function remains limited. We aimed to evaluate the association between ginseng and cognitive function through a systematic review and meta-analysis of recent randomized controlled trials (RCT).
Methods: We searched six databases: PubMed, Embase, Cochrane Library, Korean Studies Information Service System (KISS), Research Information Sharing Service (RISS), and ScienceON, for RCTs investigating the effects of ginseng on cognitive function up to April 26, 2024.
Breast cancer resistance protein (BCRP), a member of the ATP-binding cassette transporter family, plays a key role in the efflux of various drugs and is linked to multidrug resistance in cancer therapy. Flavonoids, particularly those with a flavonol backbone, have shown promise as inhibitors of BCRP activity; however, their specific inhibitory effects are not fully understood. This study explored the inhibitory effects of 77 flavonols on BCRP and identified 22 compounds with significant inhibitory activity.

Acute lung injury (ALI) is an inflammatory phenomenon characterized by hypoxia and edema. When the lungs are damaged, inflammation begins due to pro-inflammatory cytokines secreted by macrophages in the alveoli. In addition, neutrophils infiltrate the lung tissue, inducing additional inflammation.

Data were drawn from the 2013-2021 Korean National Health and Nutrition Examination Survey, encompassing 40,839 participants aged 19 and older, and were analyzed using multivariate regression models. The results revealed significant disparities between the two types of households.

Moreover, alterations in microbiome composition and its metabolites were confirmed in the colon of patients with PD. However, there has been no study that evaluates transcriptomic alterations of the nerve plexus and intestinal epithelium simultaneously using in vivo tissue of patients with PD.

In this study, we conducted single-cell RNA sequencing (scRNA-seq) on peripheral blood mononuclear cells and spatial transcriptomics using kidney allograft biopsy samples. The scRNA-seq study included four patients with borderline rejection or biopsy-proven TCMR and two with no evidence of TCMR.

Radiation-induced skin damage is a critical concern as it is often accompanied by severe inflammation and delayed wound healing. Endothelial cells have emerged as a promising therapeutic target for addressing such radiation-induced damage.

Purpose: Radiotherapy for cancer treatment or unintentional exposure to ionizing radiation causes severe damage to the unaffected tissues of the digestive system, including gastrointestinal (GI) tract. Radiation exposure leads to an inflammatory response, and uncontrolled inflammation exacerbates radiation-induced tissue injury. Bixin is a liposoluble apocarotenoid isolated from seeds, which effectively attenuates several inflammatory diseases.
View Article and Find Full Text PDFAcute lung injury (ALI) is an inflammatory lung disease. In lungs afflicted with ALI, microRNA-155 (miR-155) is over-expressed, inducing pro-inflammatory cytokines by inhibition of suppressor of cytokine signalling 1 (SOCS1). In addition, receptor for advanced glycation endproducts (RAGEs) are activated, facilitating the expression of pro-inflammatory cytokines.

Xenotransplantation, which involves the transplantation of organs, tissues, or cells from animals into humans, is emerging as a promising solution to mitigate the global shortage of human donor organs. Nonetheless, its clinical application is constrained by significant immunological and physiological barriers-most notably, the rapid rejection of xenografts by both the innate and adaptive immune systems. This review discusses critical immunological challenges such as natural antibodies, complement activation, coagulation dysregulation, and cellular immune responses mediated by T cells, macrophages, and natural killer cells.

Methods: We performed spatial transcriptomic profiling using formalin-fixed paraffin-embedded kidney biopsy specimens of controls and patients with five types of glomerular diseases using the GeoMx Digital Spatial Profiler.
Background: Examining dietary patterns in relation to mortality offers a more comprehensive view of food and nutrient intake. However, to our knowledge, the association of the Korean population's dietary patterns with mortality remains scarce and unclear. We aim to investigate the association between dietary patterns and all-cause, cardiovascular disease (CVD), and cancer mortality in the Korean population.

Herpes simplex virus thymidine kinase (HSVtk) gene therapy is a promising strategy for glioblastoma therapy. However, delivery of plasmid DNA (pDNA) encoding HSVtk into the brain by systemic administration is a challenge since pDNA can hardly penetrate the blood-brain barrier. In this study, an exosome-membrane (EM) and polymer-based hybrid complex was developed for systemic delivery of pDNA into the brain.

Here, we investigate the role of ubiquitin-specific peptidase 14 (USP14) in modulating PER stability and circadian rhythms in Drosophila. We find that overexpression of USP14 in clock cells reduces PER protein levels without altering its mRNA levels whereas USP14 knockdown increases PER protein levels, suggesting that USP14 regulates PER post-translationally.
