Discovery of novel cathepsin K inhibitors for osteoporosis treatment using a deep learning-based strategy.

Background: Cathepsin K (CTSK), a cysteine protease of the papain family, exhibits high expression in activated osteoclasts, making it a key therapeutic target for osteoporosis. However, there are currently no CTSK inhibitors available for clinical use.

Research Design And Methods: The authors employed a combination of deep learning approaches and experimental methods to identify novel CTSK inhibitors.

Atractylodes macrocephala-derived extracellular vesicles-like particles enhance the recovery of ulcerative colitis by remodeling intestinal microecological balance.

Current treatment of ulcerative colitis (UC) remains challenging, with the mainstay of therapy being 5-aminosalicylic acid-based drugs, which have limited and inconsistent results. Atractylodes macrocephala (AM) is a traditional Chinese medicine commonly used in the clinical treatment of various inflammatory diseases. Herein, we demonstrate that AM-derived extracellular vesicle-like particles (AMEVLP) can effectively modulate the gut microbiota, thereby significantly improving the treatment efficiency of UC.

Diagnostic imaging confusion in infectious spondylitis.

Background: Infectious spondylitis is a rare but increasingly recognized condition involving infectious lesions of the spine. It can affect patients of all ages and is typically caused by bacterial, fungal, or other pathogens. The infection commonly targets the vertebral bodies and intervertebral discs.

The clinical significance and potential therapeutic target of tumor-associated macrophage in non-small cell lung cancer.

One of the leading causes of cancer-related mortality globally is non-small cell lung cancer (NSCLC). It has become a significant public health concern due to its rising incidence rate and fatality. Tumor-associated macrophage (TAM) is important in the tumor microenvironment (TME) of NSCLC because they have an impact on the development, metastasis, and incidence of tumors.

Rhizoma Drynariae-derived EV-like particles alleviate osteoporosis by promoting osteogenic differentiation in BMSCs through the activation of the hsa_circ_0001275/miR-422a pathway.

Background: Osteoporosis (OP) is the most prevailing primary bone disease caused by the imbalance between bone resorption and formation. Rhizoma Drynariae-derived EV-like particles (RD-EVLP) perform the anti-osteoporosis effect by promoting the osteogenic differentiation of human bone marrow mesenchymal stem cells (h-BMSCs) which may be regulated by circular RNAs (circRNAs) and microRNAs (miRNAs). This study aimed to reveal the functional roles and mechanisms of the RD-EVLP regulating osteogenic differentiation of osteoporosis through the activation of hsa_circ_0001275 sponging miR-422a.

Aminoacetone is associated with sleep latency.

Introduction: This study conducted a targeted analysis of metabolites involved in inflammatory, oxidative stress, and neuronal pathways that were previously implicated with sleepiness based on our prior work identifying metabolites in these pathways in persons with OSA. We examine associations between sleep latency (based on the Pittsburgh Sleep Quality Index) which is an important indicator of sleep quality and daytime sleepiness, and metabolic concentrations to identify potential mechanisms linking the two.

Methods: This cross-sectional study included 88 participants newly diagnosed and untreated for OSA who underwent an overnight in-lab or at home sleep study recruited from the Emory Mechanisms of Sleepiness Symptoms Study (EMOSS).

Modic changes: From potential molecular mechanisms to future research directions (Review).

Low back pain (LBP) is a leading cause of disability worldwide. Although not all patients with Modic changes (MCs) experience LBP, MC is often closely associated with LBP and disc degeneration. In clinical practice, the focus is usually on symptoms related to MC, which are hypothesized to be associated with LBP; however, the link between MC and nerve compression remains unclear.

spondylitis in an immunocompetent patient with annular high signal around the intervertebral disks: a case report and literature review.

spondylitis is a rare fungal infection, primarily occurring in immunocompromised patients, although cases in immunocompetent individuals have also been reported. While is commonly associated with pulmonary infections, it can also cause spondylitis. Patients typically present with back pain, limb numbness, and neurological compression symptoms.

Integrative proteogenomic analysis identifies COL6A3-derived endotrophin as a mediator of the effect of obesity on coronary artery disease.

Obesity strongly increases the risk of cardiometabolic diseases, yet the underlying mediators of this relationship are not fully understood. Given that obesity strongly influences circulating protein levels, we investigated proteins mediating the effects of obesity on coronary artery disease, stroke and type 2 diabetes. By integrating two-step proteome-wide Mendelian randomization, colocalization, epigenomics and single-cell RNA sequencing, we identified five mediators and prioritized collagen type VI α3 (COL6A3).

A simple, reliable and easily generalizable cell-based assay for screening potential drugs that inhibit lipid accumulation.

Ectopic lipid deposition in the hepatocyte plays an important role in the development of nonalcoholic fatty liver disease (NAFLD), which has become one of the most common causes of chronic liver disease worldwide yet no approved drugs are currently available. In this study, a cell-based method was developed to screen potential drugs with low toxicity that inhibit lipid accumulation. In the same 96-well plate, cytotoxicity was measured using CCK8 assay, followed by lipid content detection using BODIPY 493/503 via fluorometry assay, a lipid droplet-specific fluorescent dye commonly used in microscopy and flow cytometry, but not previously reported in fluorometry.

Hypoxia studies in non‑small cell lung cancer: Pathogenesis and clinical implications (Review).

Non‑small cell lung cancer (NSCLC) is one of the most prevalent and lethal types of cancers worldwide and its high incidence and mortality rates pose a significant public health challenge. Despite significant advances in targeted therapy and immunotherapy, the overall prognosis of patients with NSCLC remains poor. Hypoxia is a critical driving factor in tumor progression, influencing the biological behavior of tumor cells through complex molecular mechanisms.

Potassium voltage-gated channel subfamily H member 2 (KCNH2) is a promising target for incretin secretagogue therapies.

Derived from enteroendocrine cells (EECs), glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) are pivotal incretin hormones crucial for blood glucose regulation. Medications of GLP-1 analogs and GLP-1 receptor activators are extensively used in the treatment of type 2 diabetes (T2D) and obesity. However, there are currently no agents to stimulate endogenous incretin secretion.
