Objective:To investigate the effects and molecular mechanisms of Wilms tumor 1-associated proteins(WTAP)on the cell biological properties of esophageal squamous cell carcinoma(ESCC)cells.Methods:31 pairs of ESCC tissues and their paired paracancerous tissues that were surgically resected at the Second Clinical Medical College of Chuanbei Medical College between September 2019 and April 2021 were collected.The esophageal cancer cells KYSE30,KYSE410,KYSE150,KYSE510,TE-1,and normal human esophageal epithelial cells HET-1A were routinely cultured.Transfection reagents were used to transfect si-NC,si-WTAP#1 and si-WTAP#2 nucleic acids into KYSE150 and KYSE510 cells.The cells were divided into si-NC,si-WTAP#1 and si-WTAP#2 groups.The expressions of WTAP and MAP3K9 mRNA were detected in the cells of each group by qPCR assay.CCK-8 assay,clone formation assay,and scratch healing assay,Transwell assay were employed to detect the effects of knockdown of WTAP expression on ESCC cell proliferation,migration,invasion and apoptosis.WB assay was used to detect the expressions of WTAP,MAP3K9,EMT and MAPK pathway-related proteins in ESCC cells of each group knocked down of WTAP;immunohistochemistry to detect the expression of WTAP proteins in ESCC tissues,immunoprecipitation of methylated RNA(MeRIP)-qPCR assay to detect the level of MAP3K9 m6A in ESCC cells,actinomycin D assay to detect the stability of mRNA of MAP3K9,and database data to analyze the expression,target genes,functional enrichment,and interacting RNA of WTAP.Results:WTAP was highly expressed in ESCC tissues and cells(P<0.05 or P<0.01 or P<0.001)and correlated with the degree of differentiation(P<0.01);the expression of WTAP mRNA and its protein were successfully knocked down in KYSE150 and KYSE510 cells(P<0.01 or P<0.001);the knockdown of WTAP significantly inhibited the proliferation,migration and invasion of KYSE150 and KYSE510 cells(P<0.05 or P<0.01 or P<0.001),and promoted the apoptosis of KYSE150 and KYSE510 cells(P<0.05 or P<0.01).Knockdown of WTAP resulted in a significant decrease in the m6A level of MAP3K9(P<0.05),and its mRNA expression level and mRNA stability were both significantly reduced(P<0.05).Database data analysis showed that WTAP target genes clustered in the MAPK signaling pathway;the expression levels of MAP3K9,p-ERK,N-cadherin,and MMP9 were significantly reduced(P<0.05 or P<0.01),and the expression level of E-cadherin was significantly elevated(P<0.05 or P<0.01)in the KYSE150 and KYSE510 cells after knockdown of WTAP.Conclusions:WTAP is highly expressed in ESCC tissues and cells and correlates with their differentiation.It promotes the stability of MAP3K9 mRNA through m6A modification,activates the MAPK pathway and thus promotes the malignant biological behaviors of ESCC cells.

Objective:To analyze the relationship between 24-hour urinary calcium (24 h UCa) level and the risk of end-stage kidney disease (ESKD), cardiovascular disease (CVD), and all-cause mortality.Methods:In the Chinese Cohort Study of Chronic Kidney Disease, we examined 3 375 patients aged 18-74 years with CKD stages 1-4. Kaplan-Meier survival and Cox proportional hazard regression models were used to test a time-to-event association between levels of 24 h UCa and incidence of ESKD, CVD, and all-cause mortality.Results:During a follow-up of 4.17 (3.37, 5.20) years, 179, 145, 104 and 38 ESKD events occurred in <0.60, 0.60-, 1.20-, ≥2.32 mmol 24 h UCa groups. Higher levels of 24 h UCa (1.20-,≥2.32 mmol) were independently associated with a lower incidence of ESKD events in patients with CKD, with HR (95% CI) of 0.71 (0.54-0.93) and 0.43 (0.29-0.64), respectively. No significant associations with CVD and all-cause mortality endpoints were detected. Conclusion:Among patients with CKD, levels of 24 h UCa displayed an association with the risk of ESKD among patients with CKD stages 1-4.

Ferroptosis, an iron-dependent programmed cell death process driven by reactive oxygen species-mediated lipid peroxidation, is regulated by several metabolic processes, including iron metabolism, lipid metabolism, and redox system. Macrophages are a group of innate immune cells that are widely distributed throughout the body, and play pivotal roles in maintaining metabolic balance by its phagocytic and efferocytotic effects. There is a profound association between the biological functions of macrophage and ferroptosis. Therefore, this review aims to elucidate three key aspects of the unique relationship between macrophages and ferroptosis, including macrophage metabolism and their regulation of cellular ferroptosis; ferroptotic stress that modulates functions of macrophage and promotion of inflammation; and the effects of macrophage ferroptosis and its role in diseases. Finally, we also summarize the possible mechanisms of macrophages in regulating the ferroptosis process at the global and local levels, as well as the role of ferroptosis in the macrophage-mediated inflammatory process, to provide new therapeutic insights for a variety of diseases.

Objective:To investigate the clinical characteristics and risk factors for disease progression after treatment in patients with post-tuberculosis chronic pulmonary aspergillosis (post-TB CPA).Methods:A retrospective cohort study was conducted on post-TB CPA patients admitted to Hangzhou Red Cross Hospital between January 2020 and December 2023. The demographic manifestation, clinical manifestation, laboratory indicators, imaging findings, and treatment strategies were collected. Patients were divided into progression group and non-progression group based on treatment outcomes, and the clinical data of the two groups were compared. Chi-square test was used for univariate analysis, and multivariate logistic regression were used to identify independent risk factors for disease progression after treatment.Results:A total of 109 post-TB CPA patients were included, and 33.9%(37/109) were in the progression group and 66.1%(72/109) in the non-progression group. Multivariate logistic regression revealed that subacute invasive aspergillosis (SAIA) (odds ratio ( OR)=14.356, 95% confidence interval ( CI) 2.923 to 70.504, P=0.001), elevated erythrocyte sedimentation rate (ESR) ( OR=5.276, 95% CI 1.505 to 18.491, P=0.009), and pulmonary fibrosis ( OR=5.030, 95% CI 1.437 to 17.612, P=0.012) were independent risk factors for disease progression. Antifungal treatment for ≥3 months was associated with a lower risk of disease progression ( OR=0.038, 95% CI 0.003 to 0.431, P=0.008). The proportion of non-progression group receiving surgical treatment was higher than that of progression group with statistical significance (31.9%(23/72) vs 5.4% (2/37), χ2=8.30, P=0.004), but the protective effect of surgery on disease progression was not confirmed by multivariate analysis ( OR=0.735, 95% CI 0.132 to 4.080, P=0.724). Conclusions:Disease progression in patients with post-TB CPA is strongly associated with SAIA, elevated ESR, and pulmonary fibrosis. Standardized anti-fungal treatment for ≥3 months significantly improves the prognosis.
