Abstract Background: The JAK2^V617F mutation plays a crucial part in the pathogenesis of myeloproliferative neoplasms (MPN), which includes polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) leading to aberrant proliferation and survival of hematopoietic cells. Alongside the challenges of drug resistance and side effects, identifying novel compounds that selectively target JAK2^V617F could provide more effective and safer therapeutic options for patients with MPNs. Materials and Methods: We employed computational approaches like high-throughput virtual screening, molecular dynamics simulations (MDS), and binding free energy calculations to identify inhibitors targeting wild and mutant JAK2 kinases. JAK2^V617F positive HEL, wild… More >

Abstract Background: Gastric cancer (GC) remains a global health burden and is often characterized by heterogeneous molecular profiles and resistance to conventional therapies. The phosphoinositide 3-kinase and PI3K and Janus kinase (JAK) signal transducer and activator of transcription (JAK-STAT) pathways play pivotal roles in GC progression, making them attractive targets for therapeutic interventions. Methods: This study applied a computational and molecular dynamics simulation approach to identify and characterize SBL-JP-0004 as a potential dual inhibitor of JAK2 and PI3KCD kinases. KATOIII and SNU-5 GC cells were used for in vitro evaluation. Results: SBL-JP-0004 exhibited a robust binding affinity for… More >

Abstract Oral ulcers, a common mucosal affliction, severely diminish patients’ quality of life due to pain and discomfort. Despite existing treatments, the frequent recurrence of oral ulcers underscores the need for more effective therapeutic options. This study aimed to investigate the inhibitory effects of Ponkan (Citrus reticulata ‘Ponkan’) extracts and their flavonoid components on oral ulcers, exploring their potential as a natural therapy. Twenty different Ponkan cultivars were selected for flavonoid extraction and analysis. Ultra-performance liquid chromatography (UPLC) and high-resolution mass spectrometry (HRMS) were utilized for substance identification, leading to the discovery of 16 flavonoid compounds. Using… More > Graphic Abstract

Abstract Background: Oleanolic acid (OA), a pentacyclic triterpenoid exhibiting specific anti-cancer properties and highly effective antioxidant activity, was isolated from traditional Chinese medicinal herbs. Conversely, the OA that impacts colon cancer (CC) cells and its underlying mechanisms remain poorly understood. Methods: The cytotoxic effect of OA alone or OA-5-Fluorouracil (5-FU) combination on normal and CC cells was analyzed by methyl thiazolyl diphenyl-tetrazolium bromide (MTT). Then, the impact of OA on CC cell lines (LoVo and HT-29) proliferation and stemness were measured using colon formation and tumorsphere formation assays. Octamer-binding transcription factor 4 (Oct4), Prominin-1 (CD133), Nanog,… More >

Abstract Background: Galectin 2 (LGALS2) is a protein previously reported to serve as a mediator of disease progression in a range of cancers. The function of LGALS2 in oral squamous cell carcinoma (OSCC), however, has yet to be explored, prompting the present study to address this literature gap. Methods: Overall, 144 paired malignant tumor tissues and paracancerous OSCC patient samples were harvested and the LGALS2 expression levels were examined through qPCR and western immunoblotting. The LGALS2 coding sequence was introduced into the pcDNA3.0 vector, to enable the overexpression of this gene, while an LGALS2-specific shRNA and… More >

Abstract Breast and lung cancers are the leading causes of mortality and most frequently diagnosed cancers in women and men, respectively, worldwide. Although the antitumor activity of chalcones has been extensively studied, the molecular mechanisms of isoliquiritigenin analog 2', 4', 4-trihydroxychalcone (metochalcone; TEC) against carcinomas remain less well understood. In this study, we found that TEC inhibited cell proliferation of breast cancer BT549 cells and lung cancer A549 cells in a concentration-dependent manner. TEC induced cell cycle arrest in the S-phase, cell migration inhibition in vitro, and reduced tumor growth in vivo. Moreover, transcriptomic analysis revealed that TEC More > Graphic Abstract

Abstract Thymic stromal lymphopoietin (TSLP) is highly expressed in the central nervous system in response to inflammation, but its exact function remains unclear. In this study, we used a model of LPS-stimulated microglia to investigate the direct impact of TSLP on microglial activation and the underlying mechanism. We measured oxidative stress, expression of microglial activation markers, and inflammatory indexes. The results show that TSLP treatment increased the expression of TSLP receptors and reduced LPS-induced oxidative stress, inflammation, and the expression of M1-type markers in microglia. Interestingly, TSLP treatment also influenced the differentiation of microglia towards the More >

Abstract Background: There is currently no safe or effective treatment for inflammatory bowel disease (IBD), which is defined as recurrent and persistent intestinal inflammation. Thymic stromal lymphopoietin (TSLP) has been shown to be associated with the pathogenesis of IBD, and the JAK2/STAT5 signalling pathway has demonstrated much promise as a novel therapeutic target for IBD. Materials and Methods: In this study, we first evaluated levels of TSLP in dextran sodium sulphate (DSS)-induced IBD mice. Second, we applied tezepelumab, an anti-TSLP monoclonal antibody (20 µg per mouse, intraperitoneally), to DSS-induced IBD mice and quantified the signs of histopathological change,… More >

Abstract Background: The development and prognosis of breast cancer are intricately linked to psychological stress. In addition, depression is the most common psychological comorbidity among breast cancer survivors, and reportedly, Fang-Xia-Dihuang decoction (FXDH) can effectively manage depression in such patients. However, its pharmacological and molecular mechanisms remain obscure. Methods: Public databases were used for obtaining active components and related targets. Main active components were further verified by ultra-high-performance liquid chromatography-high-resolution mass spectrometry (UPLC-HRMS). Protein–protein interaction and enrichment analyses were taken to predict potential hub targets and related pathways. Molecule docking was used to understand the interactions… More >

Abstract Background: Nano-selenium has been widely used in antiviral and anticancer therapy, and has the advantages of good targeting and low toxicity. For the first time, we combined male reproduction with nano-selenium to investigate its antioxidant effect. This study investigated the protective effect of lentinan functionalized selenium nanoparticles on oxidative stress injury of the hydrogen peroxide (H₂O₂)-induced Leydig cell line, TM3. Methods: The suitable concentration of nano-selenium treatment to promote cell proliferation was also discussed. The concentration of 4 μM could significantly promote the growth of TM3 cells. Oxidative stress damage was caused using an 800 μM concentration… More >
