Abstract
Dexmedetomidine hydrochloride (DEX-HCl) and sufentanil citrate (SFC) are commonly used anesthetic drugs for esophageal cancer (EC) surgery. The present study was performed to investigate the effect of DEX-HCl and SFC treatment on glucose metabolism and epithelial-mesenchymal transition in EC. Cell counting kit-8 (CCK8), clonogenic, wound healing and Transwell migration assays were performed to assess the effects of the DEX-HCl and SFC on KYSE30 cell proliferation, invasion and migration. Changes in lactate and glucose levels in KYSE30 cells were also detected. Western blot analysis was used to determine the protein expression levels of the JAK/STAT signaling pathway and glucose metabolism-related proteins. The results of CCK8, clonogenic and wound healing assays demonstrated that DEX-HCl and SFC inhibited KYSE30 cell proliferation, invasion and migration. Similarly, the combined DEX-HCl and SFC treatment significantly reduced lactate production, ATP production and glucose levels in KYSE30 cells. Western blotting indicated that DEX-HCl and SFC could reduce JAK/STAT and metastasis-related protein expression. Demonstrating a reduction in Hexokinase 2, matrix metallopeptidase 2 and 9, N-cadherin and lactate dehydrogenase A protein expression levels. The effects of DEX-HCl and SFC combined treatment were counteracted by the addition of JAK/STAT pathway activator RO8191, which suggested that DEX-HCl and SFC could serve a role in mediating the JAK/STAT signaling pathway in KYSE30 cells.

Abstract
This study aims to explore the mechanism of pyroptosis of human hepatocyte LX-2 cells induced by NaAsO2 through the miR-150-5p/SOCS1 pathway. LX-2 cells were transfected with different concentrations of NaAsO2, miR-150-5p inhibitor, and SOCS1 agonist. Cell activity, cell pyroptosis, and the expression of related genes and proteins were detected by scanning electron microscopy, CCK-8, qRT-PCR, western blot, and immunofluorescence. Compared with the control group, 10 µmol/L and 20 µmol/L NaAsO2 significantly elevated the protein expression levels of the pyroptosis-related proteins NLRP3, GSDMD, GSDMD-N, caspase1, and cleaved caspase1 as well as the mRNA levels of NLRP3, GSDMD, caspase1, IL-18, and IL-1β. The typical pyroptosis with swelling and rupture of the plasma membrane was observed through scanning electron microscopy. The expression of miR-150-5p of the NaAsO2 intervention group increased, while the expression of SOCS1 decreased; then the level of NF-κB p65 elevated. With co-treatment of miR-150-5p inhibitor, SOCS1 agonist, and NaAsO2, the cell pyroptosis was attenuated, and the expressions of NLRP3, caspase1, GSDMD, GSDMD-N, IL-18, IL-1β, p65 of the group of miR-150-5p inhibitor and NaAsO2 group, and of the group of SOCS1 agonist and NaAsO2 reduced compared with the NaAsO2 group. Arsenic exposure promotes miR-150-5p, inhibits the expression of SOCS1, and activates the NF-κB/NLRP3 pathway in LX-2 cell pyroptosis.

Abstract
Polypropylene microplastics (PP-MPs) are emerging environmental contaminants that have the potential to cause adverse effects on aquatic organisms. Reverse transcriptase quantitative real-time polymerase chain reaction (RT-qPCR) is a valuable tool for assessing the gene expression profiles under PP-MPs stress. To obtain an accurate gene expression profile of tissue inflammation and apoptosis that reflects the molecular mechanisms underlying the impact of PP-MPs on Chinese sturgeon, identifying reliable reference genes is crucial for RT-qPCR analysis. In this study, we constructed an experiment model of Chinese sturgeon exposed to PP-MPs, assessed the pathological injury, metabolic profile responses and oxidative stress in liver, evaluated the reliability of 8 reliable reference genes by 4 commonly used algorithms including GeNorm, NormFinder, BeatKeeper, Delta Ct, and then analyzed the performance of inflammatory response genes in liver, spleen and kidney with the best reference gene. HE staining revealed that the cytoplasm full small vacuoles and nucleus diameter increased were occurred in the liver cell of PP-MPs in treatment groups. Additionally, oxidative and biochemical parameters were significantly changes in the liver of treatment groups. For the reference genes in PP-MPs exposure experiments, this study screening the optimal reference genes including: EF1α and GAPDH for liver and spleen, and GAPDH and RPS18 for kidney. Besides, 2 inflammatory response genes (NLRP3, TNF-α) were chosen to assess the optimal reference genes using the least stable reference gene (TUB) as a control, verified the practicality of the select reference genes in different tissues. We also found that the low concentration of PP-MPs could induce the liver tissue damage and inflammatory response in Chinese sturgeon. Our study initially evaluated the impact of short-time exposure with PP-MPs in Chinese sturgeon and provided 3 sets of validated optimal reference genes in Chinese sturgeon exposure to PP-MPs.

Abstract
BACKGROUND Metabolic alteration drives renal cell carcinoma (RCC) development, while the impact of melatonin (MLT), a neurohormone secreted during darkness, on RCC cell growth and underlying mechanisms remains unclear. METHODS We detected concentration of metabolites through metabolomic analyses using UPLC-MS/MS, and the oxygen consumption rate was determined using the Seahorse Extracellular Flux analyzer. RESULTS We observed that MLT effectively inhibited RCC cell growth both in vitro and in vivo. Additionally, MLT increased ROS levels, suppressed antioxidant enzyme activity, and induced apoptosis. Furthermore, MLT treatment upregulated key TCA cycle metabolites while reducing aerobic glycolysis products, leading to higher oxygen consumption rate, ATP production, and membrane potential. Moreover, MLT treatment suppressed phosphorylation of Akt, mTOR, and p70 S6 Kinase as well as the expression of HIF-1α/VEGFA in RCC cells; these effects were reversed by NAC (ROS inhibitors). Conversely, MLT synergistically inhibited cell growth with sunitinib and counteracted the Warburg effect induced by sunitinib in RCC cells. CONCLUSIONS In conclusion, our results indicate that MLT treatment reverses the Warburg effect and promotes intracellular ROS production, which leads to the suppression of Akt/mTOR/S6K signaling pathway, induction of cell apoptosis, and synergistically inhibition of cell growth with sunitinib in RCC cells. Overall, this study provides new insights into the mechanisms underlying anti-tumor effect of MLT in RCC cells, and suggests that MLT might be a promising therapeutic for RCC.

Abstract
Background Renal cell carcinoma (RCC) originates from renal tubular epithelial cells and is mainly classified into three histological types, including clear cell renal cell carcinoma (ccRCC) which accounts for about 75% of all kidney cancers and is characterized by its strong invasiveness and poor prognosis. Hence, it is imperative to understand the mechanisms underlying the occurrence and progression of ccRCC to identify effective biomarkers for the early diagnosis and the prognosis prediction. Methods The mRNA level of TTC13 was quantified by RT-PCR, while the protein level was determined by western blot and immunohistochemistry (IHC) staining. Cell proliferation was measured by cck-8, and cell apoptosis was detected by flow cytometry. The binding of STAT3 to the promoter region of TTC13 was determined by the luciferase reporter assay and chip experiments. STAT3 nuclear translocation was assessed by immunofluorescence staining. Results We found that TTC13 was up-regulated in ccRCC, and TTC13 promoted cell proliferation as well as inhibited cell apoptosis and autophagy of ccRCC through wnt/β-catenin and IL6-JAK-STAT3 signaling pathways. Furthermore, TTC13 might play a role in the immune infiltration and immunotherapy of ccRCC. Mechanistically, STAT3 activated the transcription of TTC13 gene. Conclusions STAT3 directly regulated TTC13 expression through a positive feedback loop mechanism to promote ccRCC cell proliferation as well as reduce cell apoptosis and autophagy. These findings suggested new and effective therapeutic targets for more accurate and personalized treatment strategies.

Abstract
BACKGROUND Clear cell renal cell carcinoma (ccRCC) has a high degree of malignancy and poor overall prognosis in advanced and metastatic patients. Therefore, it is of great significance to find new prognostic biomarkers and therapeutic targets for ccRCC. The expression of progestin and adipoQ receptor family member 5 (PAQR5) is significantly downregulated in ccRCC compared with normal tissues, but its specific mechanism and potential biological function in ccRCC remain unclear. METHODS The expression pattern of PAQR5 and the correlation between the PAQR5 expression and clinicopathological parameters and various survival periods in ccRCC patients were analyzed by using multiple public databases and ccRCC tissues chip. Its prognostic value was analyzed by univariate/multivariate Cox regression. In addition, MTT assay, EdU staining assay, flow cytometry, wound healing assay, transwell migration and invasion assay, colony formation assay, immunofluorescence assay, and a xenograft tumor model were conducted to assess the biological function of PAQR5 in ccRCC in vitro and in vivo. RESULTS Our results indicated that the downregulation of PAQR5 was demonstrated in ccRCC tumor tissues and associated with poorer OS, DSS, and PFI. Meanwhile, the univariate/multivariate Cox regression analysis confirmed that PAQR5 might serve as an independent prognostic factor for ccRCC, and its low expression was tightly correlated with tumor progression and distant metastasis. Mechanistically, a series of gain- and loss-of-function assay revealed that PAQR5 could suppress the ccRCC proliferation, invasion, metastasis, and tumorigenicity in vitro and in vivo by inhibiting the JAK/STAT3 signaling pathway. CONCLUSION Our study revealed the tumor suppressor role of PAQR5 in ccRCC. PAQR5 is a valuable prognostic biomarker for ccRCC and may provide new strategies for clinical targeted therapy.

Abstract
Signal transducer and activator of transcription 3 (STAT3) is a cell-signal transcription factor that has attracted considerable attention in recent years. The stimulation of cytokines and growth factors can result in the transcription of a wide range of genes that are crucial for several cellular biological processes involved in pro- and anti-inflammatory responses. STAT3 has attracted considerable interest as a result of a recent upsurge in study because of their role in directing the innate immune response and sustaining inflammatory pathways, which is a key feature in the pathogenesis of many diseases, including renal disorders. Several pathological conditions which may involve STAT3 include diabetic nephropathy, acute kidney injury, lupus nephritis, polycystic kidney disease, and renal cell carcinoma. STAT3 is expressed in various renal tissues under these pathological conditions. To better understand the role of STAT3 in the kidney and provide a theoretical foundation for STAT3-targeted therapy for renal disorders, this review covers the current work on the activities of STAT3 and its mechanisms in the pathophysiological processes of various types of renal diseases.

Abstract
Dysregulated cytokine signalling is a hallmark of inflammatory bowel diseases. Inflammatory responses of the colon are regulated by the suppressor of cytokine signalling (SOCS) proteins. SOCS1 is a key member of this family, and its function is critical in maintaining an appropriate inflammatory response through the JAK/STAT signalling pathway. Dysregulation of SOCS1 protein has been identified as a causal element in colonic inflammatory diseases. Despite this, it remains unclear how SOCS1 protein is regulated. Here, we identify that SOCS1 protein is targeted for degradation by the ubiquitin proteasome system, mediated by the E3 ubiquitin ligase KIAA0317 during experimental colonic inflammation. We characterize the mechanism of protein-protein interaction and ubiquitin conjugation to SOCS1 and demonstrate that the modulation of SOCS1 protein level leads to stark effects on JAK/STAT inflammatory signalling. Together, these results provide insight into the regulation of colonic inflammation through a new mechanism of ubiquitin-based control of SOCS1 protein.

Cell Death Dis 2023; 14:232. [PMID: 37002206 PMCID: PMC10066201 DOI: 10.1038/s41419-023-05717-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 02/28/2023] [Accepted: 02/28/2023] [Indexed: 04/03/2023]
Abstract
Renal cell carcinoma (RCC) is characterized by the difficulties in early diagnosis and the propensity to metastases. For advanced RCC, sunitinib targeted therapy is the clinically recommended first-line drug and the major challenge of sunitinib treatment is adaptive resistance. Therefore, it is imperative to research the mechanisms underlying sunitinib resistance. In this study, we discovered that circPTPN12 was highly expressed in RCC tissues and was associated with poorer clinical outcomes. circPTPN12 could promote the proliferation, migration, invasion, and sunitinib resistance of RCC cells. Mechanistically, circPTPN12 was found to form a complex with hnRNPM, which was involved in the regulation of mRNA processing. The combination with circPTPN12 enhanced the ability of hnRNPM to maintain the stability of IL-6 mRNA and further activated the STAT3 signaling pathway. The study revealed that circPTPN12/hnRNPM/IL-6/STAT3 axis promoted RCC progression and sunitinib resistance, which might be a promising therapeutic target for relieving sunitinib resistance in RCC.

Mu J, Wang Y, Wang M, Zhang D, Liu M. Identification of reliable reference genes for gene expression studies in mouse models under microplastics stress. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2023; 252:114569. [PMID: 36696727 DOI: 10.1016/j.ecoenv.2023.114569] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 01/18/2023] [Accepted: 01/19/2023] [Indexed: 06/17/2023]
Abstract
Microplastics (MPs) and nanoplastics (NPs) have been deemed to be newly emerged contaminants interfering with various physiological processes closely related with gene expression alteration. Reverse transcriptase quantitative real-time polymerase chain reaction (RT-qPCR) serves as a powerful tool to assess gene expression, however highly dependent on a reliable reference gene. Therefore, it is necessary to identify stable reference genes for gene expression study under MP or NP stress. We constructed a mouse model postexposure to polypropylene microplastics (PP-MPs) to assess PP-MPs bioaccumulation in kidney, evaluate the kidney pathological changes, and then explore potential reference genes via RT-qPCR. Although the hematoxylin-eosin staining showed no obvious damage in kidney tissues, we observed significant PP-MPs accumulation in kidney using Raman spectra analysis supported by spectral multivariate analysis. The expression of 19 candidate reference genes were examined, including the commonly used ones of β-actin, glyceraldehyde 3-phosphate dehydrogenase (Gapdh), Cytochrome c oxidase subunit 4I1 (Cox4i), Histocompatibility 13 (H13) and ribosomal protein. Their expression stability and reliability were assessed by the combination of four algorithms including geNorm, NormFinder, BestKeeper and Delta Cq. The geNorm analysis revealed that the top three genes with the lowest variability were Cox4il, Rps9 and Gapdh, whereas NormFinder results ranked Rps3, Cox4il and Rps18 as the top three ones. Rpl15, Cox4i1 and Rps3 were the most reliable reference genes in BestKeeper results, and Delta Cq proposed Rps3 and Cox4il as the stable genes. The overall ranking indicated by GMR value gave the five most stable reference genes (Cox4i1, Rps3, Rps9, Rps18 and Gapdh). Three genes associated with different biochemical processes (Atp5f1, Crebbp and Dele1) were chosen to verify the characterized reference genes using the least stable gene as a control, exhibiting different expression profiles and implying the essentiality to select the reliable reference genes. Our results documented the expression fluctuations of acknowledged reference gene (Ubc) and proposed a set of reliable reference genes for future studies of gene expression profiles in MP treated mouse models.

Abstract
Sevoflurane is the most commonly used anesthetic in clinical practice and exerts a protective effect on cerebral ischemia-reperfusion (I/R) injury. This study aims to elucidate the molecular mechanism by which sevoflurane postconditioning protects against cerebral I/R injury. Oxygen-glucose deprivation/reperfusion (OGD/R) model in vitro and the middle cerebral artery occlusion (MCAO) model in vivo were established to simulate cerebral I/R injury. Sevoflurane postconditioning reduced neurological deficits, cerebral infarction, and ferroptosis after I/R injury. Interestingly, sevoflurane significantly inhibited specificity protein 1 (SP1) expression in MACO rats and HT22 cells exposed to OGD/R. SP1 overexpression attenuated the neuroprotective effects of sevoflurane on OGD/R-treated HT22 cells, evidenced by reduced cell viability, increased apoptosis, and cleaved caspase-3 expression. Furthermore, chromatin immunoprecipitation and luciferase experiments verified that SP1 bound directly to the ACSL4 promoter region to increase its expression. In addition, sevoflurane inhibited ferroptosis via SP1/ACSL4 axis. Generally, our study describes an anti-ferroptosis effect of sevoflurane against cerebral I/R injury via downregulating the SP1/ASCL4 axis. These findings suggest a novel sight for cerebral protection against cerebral I/R injury and indicate a potential therapeutic approach for a variety of cerebral diseases.

Circulating small extracellular vesicle-encapsulated SEMA5A-IT1 attenuates myocardial ischemia-reperfusion injury after cardiac surgery with cardiopulmonary bypass. Cell Mol Biol Lett 2022; 27:95. [PMID: 36284269 PMCID: PMC9594885 DOI: 10.1186/s11658-022-00395-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Accepted: 10/10/2022] [Indexed: 11/17/2022] Open
Abstract
Cardiomyocyte injury is a common complication during cardiac surgery with cardiopulmonary bypass (CPB). Studies have shown that circulating small extracellular vesicles (sEVs) are involved in the pathological process of cardiovascular diseases via delivering signaling molecules. This study aims to investigate the relationship between circulating sEV-encapsulated long noncoding RNAs (lncRNAs) and cardiac injury after CPB. Here, we found that the expression of sEV SEMA5A-IT1 in serum samples of patients after CPB was higher than that of pre-CPB serum samples. Moreover, serum-derived sEV SEMA5A-IT1 levels were negatively correlated with creatine kinase-MB (CK-MB) levels in patients who underwent CPB operation. Notably, circulating sEVs packaged with SEMA5A-IT1 could be uptaken by cardiomyocyte-like cells AC16 and increased SEMA5A-IT1 expression in AC16 cells. Upregulated SEMA5A-IT1 protected cardiomyocytes against hypoxia/reoxygenation injury, confirmed by increased cell viability, reduced cell apoptosis, and inhibited ferroptosis in AC16 cells. Mechanistically, SEMA5A-IT1 regulated the expression of B-cell CLL/lymphoma 2 (BCL2) and solute carrier family 7 member 11 (SLC7A11) through sponging miR-143-3p. Transfection of miR-143-3p mimics, BCL2, or SLC7A11 knockdown could attenuate the protective effect of SEMA5A-IT1 on cardiomyocytes. In conclusion, we propose that SEMA5A-IT1, which is transported to cardiomyocytes through circulating sEVs, is an important regulatory molecule that protects cardiomyocytes from ischemia–reperfusion injury, providing a target for the prevention and treatment of myocardial ischemia–reperfusion injury.
