OBJECTIVE To investigate the mechanism of gossypol acetic acid (GAA) in the treatment of uterine fibroids. METHODS Human leiomyoma cells SK-UT-1 were selected as objects to investigate the effects of different concentrations (5, 10, 20, 40, 80, 160 μmol/L) of GAA on the activities of cell proliferation. 4D-DIA proteomic detection and bioinformatics analysis were carried out to screen differential proteins. Gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathway analysis were performed. The expressions of top 3 proteins [N-myc downstream regulated gene 1 (NDRG1), epidermal growth factor receptor feedback inhibitor 1 (ERRFI1), CXC chemokine ligand 3 (CXCL3)] with differential fold changes in SK-UT-1 cells were determined. RESULTS 10-160 μmol/L GAA could significantly reduce the survival rate of SK- UT-1 cells (P<0.05). Proteomics results showed that a total of 921 differentially expressed proteins were obtained, including 254 up-regulated proteins and 667 down-regulated proteins. The differentially expressed proteins were mainly distributed in mitochondria, nucleus, extracellular matrix, etc. Bioinformatics results showed that differentially expressed proteins were mainly involved in signaling pathways such as PI3K/AKT (phosphoinositide 3-kinase/protein kinase B), MAPK (mitogen-activated protein kinase), TNF (tumor necrosis factor), etc., which mainly involved cell apoptosis, aging, and movement. GAA significantly decreased protein expressions of NDRG1 and CXCL3 (P<0.05), but increased protein expression of ERRFI1 (P<0.05). CONCLUSIONS The improvement effect of GAA on uterine fibroids may involve signaling pathways such as PI3K/AKT, MAPK, TNF, etc. It can improve the occurrence and development of uterine fibroids by downregulating the expressions of NDRG1 and CXCL3 proteins, upregulating the expression of ERRFI1 protein, and affecting the proliferation and apoptosis of uterine fibroid cells.

Knee osteoarthritis (KOA) is a prevalent degenerative joint disease characterized by synovial inflammation, cartilage loss. Often manifesting as joint pain and limited mobility, it severely affects the quality of life of patients. Traditional treatment methods such as pharmacological injections and surgical interventions primarily aim to alleviate symptoms but have limited effects on cartilage repair. Human umbilical cord mesenchymal stem cells (hUC-MSCs), due to their anti-inflammatory and chondrogenic capabilities, is considered a new hope for the treatment of KOA. This article synthesizes the latest research findings from both domestic and international sources to discuss the theoretical basis for the clinical application of hUC-MSCs in treating KOA, clinical study design, and efficacy evaluation. It also addresses the challenges in the clinical application of hUC-MSCs and explores future directions, in the hope of providing feasible theoretical support for the treatment of KOA with hUC-MSCs.

Journal of Clinical Hepatology 2025;41(6):1097-1104
ObjectiveTo investigate the effect and possible mechanism of prolyl endopeptidase (PREP) on a mouse model of non-alcoholic steatohepatitis (NASH) induced by high-fat diet. MethodsA total of 18 healthy male C57BL/6J mice, aged 6 — 8 weeks, were randomly divided into normal control group, NASH group, and NASH+rosmarinic acid (RA) group, with 6 mice in each group. The mice in the control group were fed with normal diet for 16 weeks, and those in the NASH group and the NASH+RA group were fed with high-fat diet for 16 weeks; the mice in the NASH+RA group were given the PREP inhibitor RA by gavage since week 9 at a dose of 100 mg/kg, once a day for 8 weeks. The mice were sacrificed after modeling and intervention, and each group of mice was observed in terms of serum inflammatory indicators, the concentration of triglyceride in the liver, and the changes in liver lipids/inflammation/liver fibrosis; NAFLD activity score (NAS) was calculated. Western blot and quantitative real-time PCR were used to measure the protein and mRNA expression levels of PREP, peroxisome proliferator-activated receptor-γ (PPAR-γ), fibroblast growth factor 21 (FGF21), and silent information regulator 1 (SIRT1) in liver tissue. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, while the least significant difference t-test and the Dunnett’s-T3 test were used for further comparison between two groups. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups and further comparison between two groups. ResultsCompared with the NASH group, the NASH+RA group had significant reductions in the serum levels of interleukin-6, tumor necrosis factor-α, and triglyceride (all P<0.05), as well as significant improvements in hepatic steatosis, hepatocyte edema, inflammatory cell infiltration, and liver tissue lesion. The NASH+RA group had a significant reduction in NAS compared with the NASH group (P<0.05), and the NASH group had an increase in perivascular collagen fiber with occasional fiber bridging, while the NASH+RA group had a slight reduction in perivascular collagen fiber compared with the NASH group. Compared with the normal control group, the NASH group had a significant increase in collagen area percentage in the liver (P<0.05), while the NASH+RA group had no significant reduction in collagen area percentage compared with the NASH group. Compared with the NASH group, the NASH+RA group had significant increases in the relative protein expression levels of PPAR-γ, FGF21, and SIRT1 (all P<0.05) and a significant reduction in the relative protein expression level of PREP (P<0.05). Compared with the NASH group, the NASH+RA group had significant increases in the relative mRNA expression levels of PPAR-γ, FGF21, and SIRT1 (P<0.05) and a significant reduction in the relative mRNA expression level of PREP (P<0.05). ConclusionPREP reduces the level of inflammation and improves NASH in mice by regulating the PPAR-γ/FGF21/SIRT1 signaling pathway.

ObjectiveTo investigate the role and mechanism of Go-Ichi-Ni-San complex subunit 1 (GINS1) in the progression of hepatocellular carcinoma (HCC) and the development of chemotherapy resistance. MethodsThe tumor database GEPIA2 was used to analyze the differential expression of GINS1 between HCC patients and healthy individuals, and pathological tissue samples were collected from 40 HCC patients who were admitted to The Affiliated Tumor Hospital of Xinjiang Medical University and the First Affiliated Hospital of Xinjiang Medical University from May 2017 to January 2021. Immunohistochemical staining was used to measure the difference in the expression of GINS1 between HCC tissue and corresponding adjacent tissue, and the correlation between the expression level of GINS1 and the clinical TNM stage of HCC was analyzed. Western blot was also used to measure the difference in the expression of GINS1 between HCC Huh7/Hep3B/Li-7/MHCC97H cell lines and normal human QSG7701 hepatocytes. The method of lentivirus transfection was used to establish the MHCC97H cell line with stable GINS1 knockdown and its negative control cell line. CCK-8 assay and colony formation assay were used to measure cell proliferative capacity; scratch assay was used to measure cell migration ability; Transwell assay was used to measure cell invasion ability; cells were treated with oxaliplatin to measure their sensitivity to chemotherapy drugs. Nude mice were used to establish a tumor-bearing model and observe the effect of GINS1 knockdown on the growth of HCC in vivo. Western Blot was used to measure the expression levels of the proteins associated with the Notch pathway and the JAK/STAT pathway. The cells were treated with the Notch receptor agonist Jagged-1 to analyze the association between GINS1 and the Notch/JAK/STAT pathway. The independent-samples t test was used for comparison of continuous data between two groups; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsThe expression of GINS1 was upregulated in HCC patients, HCC tissue, and HCC cell lines (all P<0.05), and the expression level of GINS1 was positively correlated with the clinical TNM stage of HCC (r=0.822, P=0.011). Compared with the negative control cells, the GINS1-knockdown MHCC97H cells showed significant reductions in proliferation, migration, and invasion activities (all P<0.01) and a significantly enhanced sensitivity to oxaliplatin (P<0.01). Compared with the nude mice in the control group, GINS1 knockdown caused significant inhibition of tumor weight and volume in vivo in nude mice (all P<0.001). Compared with the negative control cells, the GINS1-knockdown MHCC97H cells showed significant reductions in the expression levels of Notch1, Notch3, p-JAK2, and p-STAT3 (all P<0.05), while there were no significant differences in the overall expression levels of JAK2 and STAT3 (P>0.05). After Jagged-1 treatment, the GINS1-knockdown MHCC97H cells showed significant increases in proliferation, migration, and invasion activities and a significant reduction in sensitivity to oxaliplatin, as well as significant increases in the levels of p-JAK2 and p-STAT3 (all P<0.05). ConclusionGINS1 is upregulated in HCC and can promote HCC progression and chemotherapy resistance through the Notch/JAK2/STAT3 pathway.

Cardiovascular disease (CVD) is the most common and fatal non communicable disease in the world. Hypertension accounts for a large proportion of global non communicable diseases. Irisin was first discovered and named in 2012. As a muscle myokine, irisin has the function of regulating glucose and lipid metabolism. Exercise can promote irisin' participation in energy metabolism in the body. At the same time, it has been found that irisin can intervene in the development of hypertension and have a positive effect on the improvement of hypertension. Therefore, this paper reviews research on the relationship between irisin and hypertension, summarizes the mechanism of irisin’ action on vascular function in hypertension, and analyzes the effect of irisin on blood pressure under exercise intervention.
