Aims/hypothesis: Emerging evidence underscored the significance of leucine-rich repeat-containing G protein-coupled receptor (LGR) 4 in endocrine and metabolic disorders. Despite this, its role in LGR4 in hepatic glucose metabolism remains poorly understood. In this study we set out to test whether LGR4 regulates glucose production in liver through a specific signaling pathway.

Ethnopharmacological Relevance: TongXieYaoFang (TXYF), a classical formula used in Traditional Chinese Medicine, is renowned for its efficacy in treating chronic abdominal pain and diarrhoea. Modern research suggests that fundamental relief from these symptoms depends on complete intestinal mucosal healing, which normalises gut secretory functions. Consensus between traditional and modern medical theories indicates that TXYF is particularly suitable for treating the remission phase of ulcerative colitis (UC).

Background: African swine fever (ASF) is a highly contagious disease, and the core-shell protein p34 is an important antigen that can induce immune responses. The use of ferritin nanoparticles for the orderly and repetitive display of antigens on the particle surface can improve the immunogenicity of subunit vaccines. Here, we used the SpyCatcher/Spytag system to conjugate ferritin nanoparticles with the p34 protein (F-p34).

De novo RNA-sequencing of Wolfiporia cocos mycelia cultured with filter paper composed of cellulose as the sole carbon source revealed a total of five expressed β-glucosidase genes. Among these, the β-glucosidase named Wcbg1B-1, which is composed of 539 amino acid residues and belongs to the GH1 family, had the highest mRNA abundance, accounting for 65 % of the total mRNA of the five expressed β-glucosidases. The recombinant Wcbg1B-1 was successfully expressed in Escherichia coli, with an optimal pH of 6.

Src homology-2-containing protein tyrosine phosphatase 2 (SHP2) plays a dual role in cancer initiation and progression. Identifying signals that modulate the function of SHP2 can improve current therapeutic approaches for IFN-α/β in HCC. We showed that cAMP-dependent protein kinase A (PKA) suppresses IFN-α/β-induced JAK/STAT signaling by increasing the phosphatase activity of SHP2, promoting the dissociation of SHP2 from the receptor for activated C-kinase 1 (RACK1) and binding to STAT1.

The PBMC-derived humanized mouse model (PBMC model) may serve as an excellent tool in the field of immunology for both preclinical research and personalized therapeutic strategy development. However, single transplantation of complete PBMCs without modifications prevents the identification of cell type-specific factors that are potentially involved in modulating cell-intrinsic functions for the immune response. Here, we establish an innovative strategy for PBMC model generation, where two-step transplantations coupled with cell type-specific gene manipulation were conducted to evaluate the potential role of CD8 T cell-intrinsic factors in regulating antitumor immunity toward PDX-based tumors.

Introduction: Bone homeostasis between osteoclast bone resorption and osteoblastic bone formation is tightly regulated by a series of factors such as the receptor activator of nuclear factor-κB ligand (RANKL). Denosumab that neutralizes RANKL is effective and widely applied in the treatment of postmenopausal osteoporosis. However, factors that participated in the RANKL-related bone remodeling process in primary and secondary osteoporosis are less known.

Background: Soft tissue sarcomas (STS) are a heterogeneous group of tumors with diverse clinical and molecular characteristics, characterized by limited treatment options and poor prognosis. Immune checkpoint inhibitors (ICIs) have emerged as promising therapies for STS, yet comprehensive evaluations of their efficacy, especially in combination with other treatments, are scarce.
Methods: We conducted a systematic review and meta-analysis of clinical trials on ICIs in STS treatment, sourced from PubMed, Embase, and the Cochrane Central Register of Controlled Trials up to May 31, 2024.

With the advent of the deep learning-based colonoscopy system, the need for a vast amount of high-quality colonoscopy image datasets for training is crucial. However, the generalization ability of deep learning models is challenged by the limited availability of colonoscopy images due to regulatory restrictions and privacy concerns. In this paper, we propose a method for rendering high-fidelity 3D colon models and synthesizing diversified colonoscopy images with abnormalities such as polyps, bleeding, and ulcers, which can be used to train deep learning models.

Non-invasive prenatal testing (NIPT) not only enables the detection of chromosomal anomalies in fetuses but also generates vast amounts of ultra-low-depth sequencing data, which can be leveraged for population genomic studies. Here, we present a protocol designed for massive ultra-low-depth sequencing datasets. We detail the steps for data processing, quality control, and genotype imputation, followed by genome-wide association study (GWAS) and post-GWAS analyses.

The integration of fecal microbiota transplantation (FMT) with immune checkpoint inhibitors (ICIs) presents a promising approach for enhancing cancer treatment efficacy and overcoming therapeutic resistance. This review critically examines the controversial effects of FMT on ICIs outcomes and elucidates the underlying mechanisms. We investigate how FMT modulates gut microbiota composition, microbial metabolite profiles, and the tumor microenvironment, thereby influencing ICIs effectiveness.

Introduction/objectives: Sjogren's syndrome (SS) is a chronic inflammatory and difficult-to-treat autoimmune disease. Timosaponin AIII (TAIII), a plant-derived steroidal saponin, effectively inhibits cell proliferation, induces apoptosis, and exhibits anti-inflammatory properties. This study explored the mechanisms of action of TAIII in SS treatment by studying gut microbiota and short-chain fatty acids (SCFAs) using fecal metabolomics.

Radiotherapy (RT) is widely applied in tumor therapy, but inevitable side effects, especially for skin radiation injury, are still a fatal problem and life-threatening challenge for tumor patients. The main components of topical radiation protection preparations currently available on the market are antioxidants, such as SOD, which are limited by their unstable activity and short duration of action, making it difficult to achieve the effects of radiation protection and skin radiation damage treatment. Therefore, we designed a drug-free antioxidant hydrogel patch with encapsulated bioactive epidermal growth factor (EGF) for the treatment of radiation skin injury.

Microgravity-induced cardiac remodeling and dysfunction present significant challenges to long-term spaceflight, highlighting the urgent need to elucidate the underlying molecular mechanisms and develop precise countermeasures. Previous studies have outlined the important role of miRNAs in cardiovascular disease progression, with miR-199a-3p playing a crucial role in myocardial injury repair and the maintenance of cardiac function. However, the specific role and expression pattern of miR-199a-3p in microgravity-induced cardiac remodeling remain unclear.
