We conclude that secoemestrin C has an immunosuppressive effect on NKT and conventional T cells and has hepatoprotective activity in mouse autoimmune hepatitis. These findings provide new insights into the use of fungus-derived natural products for the treatment of autoimmune diseases.Despite significant advances in the early diagnosis and effective treatment of gastric cancer, it remains the fourth most common cancer and the second leading cause of cancer-related deaths worldwide. The zinc-fingers and homeoboxes (ZHX) family of transcriptional repressors has been shown to play a role in multiple types of cancer. However, the prognostic significance of ZHX expression in patients with gastric cancer remains unclear. Citarinostat This work studied the association between differential expression of ZHX mRNA and outcomes in patients with gastric cancer using data from the Oncomine, CCLE, Kaplan-Meier-plotter, and cBioPortal databases. Expression of ZHX3 protein was also measured by immunohistochemistry (IHC) in gastric cancer tissues. We found that increased expression of ZHX1 mRNA and decreased expression of ZHX2 and ZHX3 were correlated with better overall survival (OS) in patients with gastric cancer. Further subgroup analyses identified significant associations between ZHX1 expression and survival in select gastric cancer patients. IHC staining confirmed that the over-expression of ZHX3 was associated with worse OS, and multivariate analyses identified ZHX3 expression as an independent prognostic factor. These results suggest that the ZHX family members may serve as distinct biomarkers and prognostic factors for patients with gastric cancer.Preeclampsia (PE) is a severe gestational complication, and dysfunctional placenta plays an essential role in PE pathogenesis. Although low-dose aspirin is currently the most promising prophylactic drug for PE prevention, the exact mechanism of aspirin remains unclear. A previous study reported that treatment with low-dose aspirin could ameliorate PE-like symptoms in lipopolysaccharide (LPS)-induced PE-like mouse model. This study aimed to uncover the potential mechanism of aspirin action in PE through quantitative phosphoproteomics comparison. We established the following four groups a control (CTRL) group, an LPS-treated (L) group, an LPS + aspirin co-treatment (LA) group, and an aspirin-treated (A) group. A total of 4350 phosphosites and 4170 phosphopeptides from 1866 phosphoproteins were identified in the placenta on embryonic day 13.5. Among the significantly altered phosphoproteins identified, apoptosis-related pathways were significantly regulated in both the L group vs. CTRL group and the LA group vs. L group comparisons. We demonstrated that apoptosis was increased in the placenta of PE-like mice and was inhibited in the LA group by quantify the apoptosis-positive cells and the protein levels of cleaved caspase 3, 8, and 9. Moreover, the phosphorylation of HSP90β (S254) and GSK3β (Y216) may be a crucial factor in the aspirin-mediated regulation of apoptosis according to protein-protein interaction analysis. This study revealed that apoptosis regulation is a mechanism of aspirin action in PE, particularly in women with over-activated inflammation. The phosphorylation of HSP90β (S254) and GSK3β (Y216) could be the key intervention targets.
Renal cell carcinoma (RCC) is a renal parenchyma neoplasm with a 30% recurrence rate even when treated properly. MicroRNAs are noncoding small RNAs that are involved in cellular communication and may participate in cancer development. This study aimed to explore the relationship between miR-33b-5p expression and RCC progression and prognosis.

RT-qPCR, CCK-8 assay, wound scratch assay, transwell assay and flow cytometry assay were used to evaluate the expression and function of miR-33b-5p in RCC. Additionally, RCC samples and survival data from The Cancer Genome Atlas were used to analyze the prognostic functions of miR-33b-5p.

miR-33b-5p expression in RCC tissues and cell lines (786-O, ACHN) were found to be significantly downregulated, compared with normal tissues and cell lines (P<0.001). The miR-33b-5p mimic transfected cells showed a slower proliferation rate (P<0.01), while its invasion ability decreased by 38.16% (786-O, P<0.001) and 49.19% (ACHN, P<0.05), compared with the negative control (NC). The migration ability of both RCC lines were found to be as follows miR-33b-5p inhibitor > NC or NC inhibitor > miR-33b-5p mimic. Additionally, TCGA and RCC samples reveal that low miR-33b-5p expression is related to poor survival outcomes (univariate analysis, P=0.029; multivariate analysis, P=0.024; Kaplan-Meier survival curves, P=0.014). Target genes prediction suggests that miR-33b-5p performs its tumor-suppressive effects and prognostic role through targeting TBX15, SLC12A5, and PTGFRN.

miR-33b-5p may function as a tumor-suppressive regulator and prognostic biomarker in RCC.

The presence of high concentrations of serum inorganic phosphate in patients with end-stage renal disease leads to calcification of vascular and aortic valves. Therefore, we applied inorganic phosphate to induce the osteogenic differentiation of valvular interstitial cells (VICs) and mimic its in vivo pathophysiological effects. Calcification and inflammatory response assays determined that inorganic phosphate-osteogenic induction medium (IP-OIM) was more efficient than classic osteogenic induction medium (OIM) containing organic glycerophosphate. Levels of BMP-2, RhoA, and ROCK-1 were significantly increased in IP-OIM cells. Knockdown efficiency of BMP-2- and RhoA-siRNA in VICs was evaluated, and expression of RhoA and its downstream target ROCK-1 was decreased after BMP-2-siRNA transfection. Moreover, ROCK-1 was significantly downregulated after RhoA knockdown, whereas expression of BMP-2 was unchanged. Interference of BMP-2 had a stronger anti-calcification effect than RhoA, further identifying BMP-2 as an upstream regulator of RhoA/ROCK-1. Stimulation of VICs by IP-OIM led to increased Smad1/5/9 phosphorylation, which peaked at 60 min, while pre-treatment of VICs with the Smad1/5/9 inhibitor Compound C attenuated VICs calcification. These results suggest that IP-OIM induced VICs osteogenic differentiation via Smad1/5/9 signaling. Knockdown of BMP-2 or RhoA also decreased Smad1/5/9 phosphorylation also decreased. We conclude that the RhoA/ROCK-1 axis participates in VICs osteogenic differentiation as a "bypass mediator" of the BMP-2/Smad1/5/9 signaling pathway.
