Background: Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients. Methods: Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines. Results: Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher. Conclusion MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.

Objective:To investigate effects of human umbilical cord mesenchymal stem cell-derived exosomes(hUCMSCs-Exo)on bisphenol AF(BPAF)-induced oxidative damage and inflammatory factor release from endometrial stromal cells(hESCs).Methods:hESCs were divided into Control group,BPAF group(25 μmol/L BPAF treatment),BPAF+Exo group(25 μmol/L BPAF+hUCMSCs-Exo treatment),BPAF+Exo+LY group(25 μmol/L BPAF+hUCMSCs-Exo+10 μmol/L LY294002 treatment).Cell prolifera-tion was detected by MTT assay;apoptosis,intracellular ROS level,and mitochondrial membrane potential level were detected by flow cytometry;protein expressions of Bcl-2,Bax,Cleaved-caspase-3 and PI3K/AKT signaling pathway were detected by Western blot;mRNA expressions of inflammatory factors TNF-α,IL-6 and IL-1β were detected by RT-qPCR.Results:Compared with Control group,hESCs survival rate was gradually decreased(P<0.01),apoptosis rate was gradually increased with the increased concentration of BPAF(≥25 μmol/L).Compared with Control group,BPAF group showed increased ROS level,decreased mitochondrial membrane potential level,increased Bax and Cleaved-caspase-3 protein expressions,and decreased Bcl-2,p-PI3K and p-AKT protein expressions.Compared with BPAF group,cell survival rate of BPAF+Exo group was increased(P<0.01),ROS level decreased,mitochondrial membrane potential level increased,expressions of Bax and Cleaved-caspase-3 proteins decreased,and expressions of Bcl-2,p-PI3K and p-AKT increased.Compared with BPAF+Exo group,expressions of Bax and Cleaved-caspase-3 protein in cells of BPAF+Exo+LY group were increased,while expressions of Bcl-2,p-PI3K and p-AKT protein were decreased.Expressions of inflammatory factors TNF-α,IL-6 and IL-1β mRNA were significantly up-regulated in BPAF group compared with Control group(P<0.01),and expressions of inflammatory factors mRNA were significantly down-regulated in BPAF+Exo group compared with BPAF group(P<0.05).Conclu-sion:BPAF(≥25 μmol/L)inhibits proliferation of hESCs and promoted apoptosis.hUCMSCs-Exo inhibits BPAF-induced oxidative dam-age and inflammatory factors expressions in hESCs through PI3K/AKT signaling pathway.

Nine novel compounds, comprising seven tetrahydroanthraquinones (auxarthrolones A-G, 1-7), a γ-butenolide glycoside (malfilamentoside E, 26), and a γ-butenolide (auxarthrolide A, 27), together with eighteen known compounds (8-25) were isolated from rice-based solid culture of Auxarthron umbrinum (A. umbrinum) DSM3193 using the one strain many compounds (OSMAC) approach. The structural elucidation of these compounds was accomplished through nuclear magnetic resonance (NMR), mass spectrometry (MS), and NMR calculation combined with DP4+ analysis or MAEΔΔδ parameter, while the absolute configurations of new compounds were established through single-crystal X-ray diffraction, electronic circular dichroism (ECD) spectroscopic data analysis and/or chemical derivatization. Austrocortilutein (10) and auxarthrol H (14) demonstrated moderate cytotoxicity against U87 and U251 [half maximal inhibitory concentration (IC₅₀) 3.5-12.1 μmol·L^-1]. Additionally, auxarthrolone A (1), auxarthrol H (14), eupolyphagin B (15), and 7-hydroxy-2-(2-hydroxypropyl)-5-methylchromone (17) exhibited torsional effects on fibroblast proliferation challenges induced by oleic acid, thus demonstrating fibroblast proliferation-promoting activity.
