Neddylation is a crucial posttranslational modification that involves the attachment of neural precursor cell-expressed developmentally downregulated protein 8 (NEDD8) to a lysine residue in the substrate via the sequential actions of the E1 NEDD8-activating enzyme (NAE) (E1), E2 NEDD8-conjugating enzyme (E2), and E3 NEDD8-ligase (E3). The most extensively studied substrates of neddylation are members of the cullin family, which act as scaffold components for cullin ring E3 ubiquitin ligases (CRLs). Since cullin neddylation activates CRLs, which are frequently overactive in tumors, inhibiting neddylation has emerged as a promising strategy for developing novel antitumor therapies. This review explores the antitumor effects of inhibiting neddylation that leads to the inactivation of CRLs and provides a summary of known inhibitors that target protein-protein interactions (PPIs) within the neddylation enzymatic cascade.

ObjectiveTo investigate the current status and related factors of maternal influenza vaccination willingness among pregnant and postpartum women in Shanghai and Liaoning Province, China, and to explore the facilitators and barriers affecting vaccination uptake, so as to provide references for future practices in promoting maternal influenza immunization in China. MethodsA convergent mixed-methods research was conducted. From January to March 2024, a questionnaire survey was conducted among women attending prenatal and postnatal care at 7 medical institutions in Shanghai and Dalian, Liaoning Province, which aimed to assess pregnant women’s knowledge about influenza vaccine and their willingness to vaccination during pregnancy, as well as to identify the related factors. In addition, purposive sampling method was used to conduct in-depth interviews with pregnant women and perinatal healthcare service providers to explore their perspectives on influenza vaccination during pregnancy, including the reasons for their willingness or unwillingness to receive ( or recommend) the vaccine, and the relevant facilitators and barriers to vaccination. ResultsA total of 366 pregnant and postpartum women participated in the questionnaire survey, and 9.56% (35/366) of them were willing to receive the influenza vaccine during pregnancy. The results of multivariate logistic stepwise regression analyses showed that primipara (aOR=0.158, 95%CI: 0.037‒0.671, P=0.012), family members’ support for influenza vaccination during pregnancy (aOR=0.015, 95%CI: 0.003‒0.082, P<0.001) were associated with higher willingness to receive influenza vaccine during pregnancy. Absence of influenza infection during pregnancy (aOR=5.383, 95%CI: 1.801‒16.092, P<0.001), and lack of knowledge regarding influenza vaccination during pregnancy (aOR=11.294, 95%CI: 3.593‒35.496, P<0.01) were associated with lower willingness to receive influenza vaccine during pregnancy. Qualitative findings indicated that the facilitators to vaccination willingness among pregnant and postpartum women included the recommendation of healthcare service providers, adequate knowledge of influenza vaccine information and family members’ support for vaccination. Conversely, the barriers to vaccination willingness included low recommendation from the healthcare service providers, lack of knowledge about the safety of influenza vaccine during pregnancy and inadequate attention to influenza and influenza vaccine. ConclusionThe willingness to receive influenza vaccination among pregnant and postpartum women in Shanghai and Liaoning Province is relatively low. It is recommended that China should promptly improve the evidence-based system for the safety and efficacy of influenza vaccines for pregnant and postpartum women, along with an establishment of the mechanism for addressing adverse reactions. Furthermore, it is essential to enhance educational outreach to pregnant and postpartum women, their families, and healthcare service providers, thereby increasing the accessibility of information regarding influenza vaccination, which are expected to enhance the willingness of pregnant and postpartum women to receive the vaccine.

Objective:To explore the effects and potential mechanisms of cell growth regulator 1 ( CGREF1) with an EF hand domain in colorectal cancer proliferation and migration. Methods:Fifty paraffin specimens of colorectal cancer tissues and corresponding paracancerous tissues were selected from January 2023 to January 2024 from the Northern Jiangsu People's Hospital Affiliated to Yangzhou University for analysis, and TCGA, GDSC, KMPLOT and STRING databases were used to explore the expression, prognosis, immune microenvironment, drug sensitivity and related signaling pathway functions of CGREF1 in colorectal cancer. Tissue and cellular expression levels of CGREF1 were analyzed by immunohistochemistry and qRT-PCR. Lentiviral-mediated CGREF1 overexpression in SW-620 cells (OE- CGREF1 vs NC groups) was functionally characterized through CCK-8 proliferation assays, colony formation tests, and scratch wound healing migration assays, with mechanistic investigation via Western blot analysis of apoptosis markers, invasion-related proteins, and RAS/RAF/ERK pathway components. In vivo tumorigenicity was assessed by subcutaneous injection of control or CGREF1-overexpressing SW620 cells in nude mice ( n=3 per group) with tumor growth monitoring. Software of GraphPad Prism 9 was used for statistical analysis of experimental data. Results:CGREF1CGREF1RASERK Studies based on databases, clinical samples and colorectal cancer cell line analyses demonstrated that CGREF1 is downregulated in colorectal cancer, where low CGREF1 expression showed positive correlation with tumor diameter and invasion depth. CGREF1 is closely related to tumor immune infiltration microenvironment and sensitivity to multiple anti-tumor drugs. Overexpression of CGREF1 promoted cell apoptosis while inhibiting cell proliferation, invasion and migration. Overexpression of CGREF1 downregulated the expression levels of RAS, ERK and P-P38/MAPK pathway proteins. CGREF1 inhibited tumor growth in vivo. Conclusion:CGREF1 can inhibit the proliferation, colony formation, and migration of CRC cells through the RAS/ERK/MAPK pathway.

The incidence of diarrhea-predominant irritable bowel syndrome(IBS-D)remains high,with microRNA(miRNA)-mediated intestinal barrier dysfunction,visceral hypersensitivity,low-grade inflammation,and dysbiosis playing significant roles in its pathogenesis.Traditional Chinese medicines can treat IBS-D by directly or indirectly targeting miRNAs to regulate multiple pathways and targets in a coordinated manner.This article systematically reviews the involvement of miRNAs in the pathogenesis of IBS-D and the progress of traditional Chinese medicine interventions.It explores the relationship between traditional genetics,epigenetics,and the Chinese medicine concepts of'kidney'and'spleen'in terms of congenital and acquired interactions from a molecular biology perspective.This review thus provides a reference for exploring the micro-material basis of the'Zang-Xiang'theory of traditional Chinese medicine,and offers new ideas and method for the effective treatment of IaBS-D using traditional Chinese medicine.

Objective:To investigate the changes of dynamic functional brain network connectivity in patients with Parkinson disease(PD) using Hidden Markov model(HMM), and to analyze the correlation between dynamic functional parameters and clinical parameters.Methods:Forty-eight PD patients(PD group) and thirty-three healthy controls(HC group) were included from 2019 to 2023. The cognitive function was assessed using the Montreal cognitive assessment (MoCA), and motor status was assessed using the unified Parkinson's disease rating scale Ⅲ(UPDRS-Ⅲ) in PD group.HMM technique was used to analyze the dynamic functional brain network connectivity, and the dynamic higher-order index fractional occupancy(FO), switching rate(SR), and mean dwell time(MDT) were obtained. Two independent samples t-test was used to calculate the differences between groups of functional connectivity matrices in different states, and Mann-Whitney U test was used to calculate the differences between groups of dynamic higher-order indicators in different states. Spearman correlation analysis was used to calculate the correlation between dynamic higher-order parameters and clinical parameters in the PD group. Results:The HMM was used to construct 6 spatial states for all subjects.MDT was significantly higher in PD group(24.93(19.73)) in state 1 sparse junctions than that in HC group(17.63(14.80)) ( Z=-2.030, P=0.042), but significantly lower MDT was showed in PD group(6.00(3.00)) in state 5 tight junctions than that in HC group(9.75(7.70)) ( Z=-2.210, P=0.027).FO in state 3 was negatively correlated with MoCA score in PD group( r=-0.331, P=0.022).FO in state 5 was positively correlated with UPDRS-Ⅲ score in PD patients( r=0.412, P=0.004), and MDT in state 5 was positively correlated with UPDRS-Ⅲ score( r=0.448, P=0.001). Conclusion:HMM can capture the transient changes of dynamic brain network, which can provide some value for the study of dynamic brain network in patients with Parkinson disease.

Objective To investigate the mechanism underlying gasdermin E(GSDME)-mediated pyroptosis in radiation-induced intestinal injury and to find out whether gasdermin(GSDM)family members regulate pyroptosis through similar signaling pathways.Methods Human normal colon epithelial cells(NCM460)and human colon cancer cells(HT-29)were exposed to radiation of different doses and durations before pyroptosis indicators were evaluated by observing pyroptotic bubbles,cell survival,and the cleavage of pyroptosis execution proteins.HT-29 cells overexpressing GSDME were subjected to radiation,followed by enrichment analysis of pyroptosis-related differentially expressed genes using RNA-seq.Results Radiation induced substantial pyroptosis in NCM460 cells.Overexpression of GSDME in HT-29 cells resulted in substantial radiation-induced pyroptosis.The pyroptosis state of human intestinal cells was simulated in the HT-29 model cell line.Overexpressions of GSDME-N and GSDMD-N resulted in the expression of more than 50％ of the differentially expressed genes in the pyroptosis state.Sequencing analysis showed that the genes in the pyroptosis state were mainly overrepresented in immune response,inflammatory response,and Rapl signaling pathway.Conclusion GSDME activation can mediate radiation-induced pyroptosis by producing GSDME-N fragments.GSDM family members participate in pyroptosis in a similar mode of regulation.Furthermore,radiation-induced activation of GSDME/D may regulate pyroptosis through immune response,inflammatory response,and Rap1 signaling pathway.

Objective To investigate the correlation between uric acid to high-density lipoprotein cholesterol ratio(UHR)and late recurrence after radiofrequency ablation in patients with non-valvular atrial fibrillation(AF).Methods The clinical data of 586 patients with non-valvular AF underwent catheter radiofrequency ablation for the first time from January 2018 to January 2022 were selected,and the study population was classified into a low-value group(n=196),a medium-value group(n=195),and a high-value group(n=195)according to the trichoto-mous method based on the UHR value,with late recurrence of AF as the endpoint event of the follow up.The gener-al data and laboratory indexes were compared among the three groups.Survival curves were estimated and plotted u-sing the Kaplan-Meier method.Multivariate COX regression analysis was used to evaluate the independent correla-tion between UHR and recurrence of AF after ablation,followed by subgroup analysis.Results Late recurrence of AF was documented in a total of 182(31.1％)patients during the follow-up time.The Kaplan-Meier survival curve showed a gradual decrease in the maintenance rate of sinus rhythm across the UHR low-value group,middle-value group,and high-value group(Log-rank test,P＜0.001).In the fully-adjusted model,compared with the patients in the low-value group,the medium-value and high-value groups had a post-ablation late recurrence of AF with HR(95％CI,P)were 1.56(0.99-2.42,P=0.057)and 2.03(1.28-3.23,P=0.003),respectively.Subgroup a-nalysis showed that the association between UHR and late recurrence of AF after ablation was remarkable among pa-tients with aged≥60 years,BMI≥25 kg/m2,persistent AF,LAD≥4.3 cm,hypertension,without heart failure and without hyperlipidemia.Conclusion Higher UHR values in patients with non-valvular AF are independently asso-ciated with an increased risk of late recurrence of AF after radiofrequency ablation procedures.
