Juanbi Qianggu Formula inhibits fibroblast-like synovicytes activation via repressing LncRNA ITSN1-2 to promote RIP2 K48 ubiquitination.

Background: Long non-coding RNA ITSN1-2(lncRNA ITSN1-2) promotes fibroblast-like synovicytes (FLS) proliferation and suppress apoptosis through activation of the NOD2/RIP2 signaling pathway, thereby exacerbating synovitis in Rheumatoid arthritis (RA) pathology. Juanbi Qianggu Formula (JBQG), a clinically efficacious traditional Chinese medicine, has shown significant efficiency in inhibiting FLS activation in RA and alleviating disease progression in RA patients. However, the molecular mechanism underlying JBQG's anti-arthritic effects remains incompletely understood, particularly regarding its potential to modulate lncRNA ITSN1-2-mediated NOD2/RIP2 signaling in FLS activation.

Study on the risk factors for colorectal polyp recurrence: a cross-sectional retrospective cohort study.

Objective: To investigate the factors associated with the recurrence of colorectal polyps.

Methods: Data on polyp recurrence and related factors, including gender, age, BMI, family history, smoking history, alcohol consumption history, gallbladder disease history, food allergy, polyp size, number, and pathological classification, (Hp) infection, parathyroid hormone, gastrin, and blood lipid levels, were collected as exposure factors. Polyp recurrence was used as the outcome measure.

Tumor vascular normalization by B7-H3 blockade augments T lymphocyte-mediated antitumor immunity.

Triple-negative breast cancer (TNBC), defined by the absence of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2), presents unique clinical challenges and generally predicts a less favorable prognosis. Despite recent advancements in TNBC treatment, a subset of patients remains resistant to immunotherapy. B7-H3, a member of the B7 family of immune checkpoints, is correlated with poor outcomes in various cancers and is distinctively expressed in tumor vasculature, marking it as a potential biomarker for tumor-associated endothelial cells.

Deubiquitination of aryl hydrocarbon receptor by USP21 negatively regulates T helper 17 cell differentiation.

Aryl hydrocarbon receptor (AhR) is a key transcription factor that modulates the differentiation of T helper 17 (Th17) cells. How AhR is regulated at the post-translational level in Th17 cells remains largely unclear. Here, we identify USP21 as a newly defined deubiquitinase of AhR.

The effect of JuanBiQiangGu granules in combination with methotrexate on joint inflammation in rheumatoid arthritis: a randomized controlled trial.

Rheumatoid arthritis (RA) joint inflammation severely affects joint function and quality of life in patients and leads to joint deformities and limb disability. The non-steroidal anti-inflammatory drugs used in the treatment of RA do not fully control the progression of joint inflammation and bone destruction and have notable adverse reactions. Traditional Chinese medicine formula JuanBiQiangGu Granules (JBQG) are commonly used for the treatment of RA inflammation and delay of bone destruction, but has not been evaluated through high-quality clinical studies.

Platelet lysate induces chondrogenic differentiation of umbilical cord-derived mesenchymal stem cells by regulating the lncRNA H19/miR-29b-3p/SOX9 axis.

Platelet lysate (PL) has been shown to induce chondrogenic differentiation of human umbilical cord-derived mesenchymal stem cells (hUCMSCs). However, the underlying mechanism is still not clear. The aim of this study was to investigate whether long noncoding RNA H19 is involved in this process.

Knockdown of TRPV4 suppresses osteoclast differentiation and osteoporosis by inhibiting autophagy through Ca -calcineurin-NFATc1 pathway.

The aim of this study is to evaluate the effect of transient receptor potential vanilloid 4 (TRPV4) on osteoclast differentiation and osteoporosis, and to investigate the underlying mechanism. The results showed that TRPV4 expression and intracellular Ca concentration were significantly upregulated in macrophage colony-stimulating factor (M-CSF)-stimulated and receptor activator of nuclear factor κΒ ligand (RANKL)-stimulated RAW264.7 cells.

Icariin possesses chondroprotective efficacy in a rat model of dexamethasone-induced cartilage injury through the activation of miR-206 targeting of cathepsin K.

The present study aimed to investigate the articular cartilage and chondrocytes of dexamethasone (DXM)-induced cartilage injuries in rats in response to treatment with icariin, as well as the implicated molecular mechanism. Effects of icariin on bone metabolism and articular cartilage in experimental rats were investigated. Subsequently, the present study assessed dysregulated microRNA (miRNA) in the articular cartilage of experimental rats, and validated the significant miRNA and their targets.

Berberine affects osteosarcoma via downregulating the caspase-1/IL-1β signaling axis.

Osteosarcoma is one of the most devastating cancers with associated poor prognosis. Chronic bone inflammation frequently predisposes to tumorigenesis and progression of osteosarcoma. In the tumor inflammatory microenvironment, caspase-1 and its processed cytokines such as interleukin 1β (IL-1β) play an important role in the occurrence and development of cancer.

High glucose prevents osteogenic differentiation of mesenchymal stem cells via lncRNA AK028326/CXCL13 pathway.

Background: High glucose (HG) often induces unfavorable effects on proliferation and differentiation of mesenchymal stem cells (MSCs). This study aimed to explore potential molecular pathways underlying HG functional mechanism during osteogenic differentiation of MSCs, involving lncRNA AK028326 and CXCL13.

Methods: Murine bone marrow-derived MSCs were cultured in osteogenic-inducing medium supplemented with high glucose level at 25mM or 5.
