Analysis of differentially expressed proteins and regulatory networks in cardiomyocytes after silencing CHAF1B based on label-free protein mass spectrometry Kang Yanhong, Gu Aiqin, Zhang Ying, Huang Shuai Journal of Capital Medical University    2024, 45 (2): 312-321.   DOI: 10.3969/j.issn.1006-7795.2024.02.020 Abstract （188）      PDF（pc） （6236KB）（153）       Knowledge map    Save Objective  To analyze differentially expressed proteins in cardiomyocytes after chromatin assembly factor 1 subunit B (CHAF1B) gene knockdown and predict the regulatory network, so as to provide reference for finding the potential therapeutic targets which can promote myocardial cell repair. Methods  Cell transfection and Western blotting methods were used to screen effective small interfering RNA (siRNA). Effective siRNA was used to knock down CHAF1B in human cardiac AC16 cells and then cell viability was detected by cell counting kit-8 method. The total protein was extracted, quantified, reduced, alkylated and then cleaved into peptides by trypsin. The peptides were identified by liquid chromatography with tandem mass spectrometry method. Differentially expressed proteins were identified by searching UniProt protein resource. Gene Ontology (GO) analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment, and protein-protein interaction networks (PPI) analysis were conducted. Results  The survival of cardiomyocytes was significantly inhibited after CHAF1B gene knockdown by effective siRNA; the identification results of label-free protein quantitative mass spectrometry showed that there were 69 differentially expressed proteins, of which 50 proteins were significantly up-regulated (fold change≥2，P＜0.05) and 19 were significantly down regulated (fold change≤0.5，P＜0.05). GO analysis showed that these proteins mainly participated in biological processes such as macromolecular composite subunit matrix, cell component biogenesis and assembly, mainly distributed in the cytoplasm, vesicles and other regions, and played molecular functions such as protein binding. KEGG pathway enrichment and PPI analysis showed that the differentially expressed proteins participated in 10 signaling pathways such as proteasome, aminoacyl tRNA biosynthesis, endocytosis, pyrimidine metabolism, and amino acid biosynthesis, etc. The significantly up-regulated proteins such as proteasome subunit alpha type-2 and beta type-7 as well as 26S proteasome regulatory subunit 6B and 10B participated in the proteasome pathway; seryl-tRNA synthetase, glycine-tRNA synthetase, glutamine-tRNA synthetase and lysine-tRNA synthetase mediated aminoacyl tRNA biosynthesis. The significantly down regulated proteins, including actin-related protein 2/3 complex subunit 3 and heat shock 70 000 protein 1-like, participated in endocytosis; ribonucleoside-diphosphate reductase large subunit mediated pyrimidine metabolism. The real time quantitative polymerase chain reaction results confirmed that after transfection with CHAF1B siRNA, the mRNA levels of the gene ARPC3, which synthesized the skeletal related protein 2/3 complex subunit 3, and the key gene QARS1 for aminoacyl tRNA biosynthesis, were significantly reduced in cardiomyocytes. Conclusion  CHAF1B is a key protein for the survival of cardiomyocytes and participates in the regulation of various biological processes in cardiomyocytes. Referring to its regulatory network can help identify intervention steps that promote myocardial cell repair. Reference | Related Articles | Metrics

Effect of the ribosome biogenesis factor BMS1 on proliferation of neuroblastoma cells Guo Jinxin, Jia Anna, Zhan Shijia, Zhang Yao, Zhang Xuan, Guo Yongli, Chang Yan Journal of Capital Medical University    2025, 46 (2): 296-305.   DOI: 10.3969/j.issn.1006-7795.2025.02.016 Abstract （135）      PDF（pc） （9341KB）（146）       Knowledge map    Save Objective  To elucidate the functional role and underlying mechanisms of the ribosome biogenesis factor BMS1 in neuroblastoma (NB) cellular proliferation. Methods  We utilized the R2 genomics analysis and visualization platform to analyze the correlation between BMS1 expression levels and clinical characteristics of NB children. The BMS1 mRNA level in three human neuroblastoma cells SK-N-BE(2), BE(2)-C, IMR-32 and two normal cells hTERT RPE-1, IMR-90 was detected by real-time quantitative polymerase chain reaction (RT-qPCR). Two distinct small interfering RNA (siRNA) sequences were used to target BMS1 mRNA in NB cells SK-N-BE(2) and BE(2)-C, with normal cells hTERT RPE-1 serving as controls. We used RT-qPCR to quantify the mRNA levels of BMS1 and two key neuroblastoma-associated molecules (MYCN and p53). After transfection with siRNA, cellular proliferation was detected by various experimental approaches: crystal violet staining, real-time cell analysis (RTCA), colony-forming unit assay and immunofluorescence. Results  By analyzing two independent neuroblastoma clinical cohorts (GSE85047/NRC-283 and Westermann-144 datasets), it was found that the BMS1 mRNA level in MYCN-amplified NB was significantly higher than that in MYCN-non-amplified NB (P<0.05). Furthermore, the overall survival rate of NB children in the BMS1 high-expression group was decreased (P<0.05). Consistent with these clinical observations, the BMS1 mRNA level in NB cells SK-N-BE(2), BE(2)-C and IMR-32 was significantly higher than that in normal cells hTERT RPE-1, IMR-90 (P<0.05).  The targeted transient knockdown of BMS1 in NB cell lines SK-N-BE(2) and BE(2)-C resulted in decreased intracellular MYCN mRNA expression levels (P<0.05), significantly reduced cell proliferation capacity and colony-forming ability (P<0.05). Immunofluorescence revealed that the expression of Ki-67, a proliferation marker, was decreased (P<0.05). At the molecular level, RT-qPCR showed that  the p53 mRNA level was significantly elevated in the BMS1-knockdown groups (siBMS1-1# and siBMS1-2#) compared with the control group (P<0.05). However, transient knockdown of BMS1 had no significant impact on the proliferative capacity of normal cells hTERT RPE-1. Conclusion  BMS1 expression was up-regulated in MYCN-amplified NB and negatively correlated with the prognosis of the NB children. Mechanistically, interfering with BMS1 expression may transcriptionally activate p53 in NB cells, thereby inhibiting their proliferative ability, while having minimal impact on normal cells growth kinetics. These findings suggest that BMS1 serves as an important proliferation driver in NB and is expected to be a promising therapeutic target for NB children, particularly MYCN-amplified pediatric patients.

Chronic diseases and BPH diagnoses were obtained through a questionnaire survey. Logistic regression analysis was performed to identify independent risk factors for BPH. Restricted cubic splines (RCS) were used to explore the nonlinear relationship between variables and BPH prevalence, while stratified analyses were conducted to assess the differential impact of chronic diseases on BPH prevalence in different subgroups.Results  Compared to patients without BPH, those with BPH had a significantly higher prevalence of comorbid chronic diseases, including hypertension, diabetes, chronic respiratory diseases, chronic heart disease, stroke, chronic kidney disease, chronic digestive diseases, arthritis or rheumatism, depression, and memory-related disorders. Multivariable Logistic regression analysis indicated that factors such as the 10-item Center for Epidemiological Studies Depression Scale (CESD-10) scores (OR = 1.043, 95% CI: 1.022－1.063, P < 0.001), chronic respiratory disease (OR = 1.518, 95% CI: 1.143－1.998, P = 0.003), chronic heart disease (OR = 1.515, 95% CI: 1.143－1.998, P = 0.003),  chronic kidney disease (OR = 2.384, 95% CI: 1.799－3.137, P < 0.001), and chronic digestive disease (OR=1.427， 95%CI：1.129-1.796,P=0.003) were independently associated with the occurrence of BPH. RCS analysis demonstrated no non-linear association between age, BMI, and CESD-10 scores and BPH. Stratified analysis revealed that the influence of these chronic conditions on BPH remained constantly stable across different subgroups.Conclusion  BPH is commonly comorbid with various chronic diseases. Future treatment strategies for BPH should consider the shared pathological mechanisms between BPH and these chronic conditions, with a focus on integrated interventions targeting common pathways.

Methods  In this study, a statistical shape model of the humerus was constructed using the three-dimensional model data of 60 collected humerus cases. The principal component analysis method was adopted to reveal the main patterns of humerus anatomical variations and their contribution rates. Results  The results showed that the first five principal components (PC01-PC05) collectively explained 96. 6% of the total anatomical variations. Among them, PC01 and PC02 were the main components, contributing 66. 6% and 23. 5% of the variations respectively. PC01 mainly reflects the scaling effect of the overall size (length/width) of the humerus, while PC02 reveals the length variation characteristics independent of the overall scaling, which may reflect individualized differences. The subsequent principal components (PC03-PC05) depicted the local morphological characteristics and fine changes of the proximal and distal humerus. Conclusion  The statistical shape model constructed in this study provides a reliable digital basis for personalized prosthesis design, surgical planning and biomechanical simulation.

Methods  This study included 9 228 individuals who met the inclusion and exclusion criteria from the Beijing Health Management Cohort. The cumulative exposure, cumulative exposure burden and high exposure time of SUA/Scr were calculated based on the values of SUA/Scr in three physical examinations in 2010 to 2011 (visit 1), 2012 to 2013 (visit 2), and 2014 to 2015 (visit 3). Carotid plaque was diagnosed by carotid ultrasound, and the follow-up was until December 31, 2021. Logistic regression model was used to analyze the association between SUA/Scr cumulative exposure indicators and carotid plaque occurrence, and sensitivity analysis was performed by excluding the participants with the usage of antihypertensive drugs, or glucose-lowering drugs, or lipid-lowering drugs. Results  The mean age of the study population was (48.89±10.22) years, and 5 846(63.35%) participants were males. The participants were divided into four groups according to the quartiles of SUA/Scr cumulative exposure, namely Q1-Q4 groups. After adjusting for covariates in models, compared with Q1 group, the ORs (95%CIs) of incident carotid plaque in Q2, Q3 and Q4 groups were 1.221 (95%CI：1.066-1.400), 1.255(95%CI： 1.095-1.439) and 1.478 (95%CI：1.287-1.697). Cumulative exposure burden greater than 0 (OR=1.223，95%CI：1.109-1.349) and high exposure time of 6 years (OR=1.332，95%CI：1.171-1.515) were both associated with increased risk of carotid plaque occurrence. Sensitivity analysis excluded participants with the usage of any antihypertensive drugs, glucose-lowering drugs, or lipid-lowering drugs. The results were similar to those in main analysis. Conclusion Cumulative exposure, cumulative exposure burden and high exposure time of SUA/Scr were associated with increased risk of incident carotid plaque. In the primary prevention of carotid plaque, we should focus not only on SUA/Scr value at a single point time, but also on long-term monitoring of SUA/Scr values.

Methods  Forty male SD rats were divided into four groups：sham group, sepsis group, vagus nerve stimulation（VNS）group, and alpha7 nicotinic acetylcholine receptors（α7nAChR）antagonist group（n=10）. Rats in sham injury group only underwent laparotomy to expose the cecum, and then the cecum was returned to the abdominal cavity. Sepsis rat model was constructed by cecal ligation and perforation（CLP）. Rats in VNS group were given electrical stimulation on left cervical vagus nerve for 20 min after CLP. Rats in α7nAChR antagonist group were intraperitoneally injected with 2 mg/kg methyllycaconitine（MLA） at 30 min before CLP. At 24 h after CLP, serum of rats was collected to detect levels of blood urea nitrogen（BUN）, serum creatinine（Scr）, tumor necrosis factor-α（TNF-α）and interleukin-6（IL-6）by biochemical and enzyme-linked immunosorbent assay（ELISA）. The 24 h urine volume of each rat was collected, and the 24 h urine volume per kilogram body weight of each rat was calculated. Urinary neutrophil gelatinase-associated lipocalin（NGAL）and kidney injury molecule-1（KIM-1）were analyzed by ELISA. hematoxylin-eosin (HE) staining and TdT-mediated dUTP nick-end labeling (TUNEL) staining were performed to evaluate renal histopathological changes and tubule cell apoptosis. Results  ① The levels of BUN, Scr, TNF-α and IL-6 of rats in sepsis group were significantly higher than those in sham group and VNS group（P<0.01）. ② The 24 h urine volume per kilogram body weight of rats in sepsis group was significantly lower than that in sham group and VNS group （P<0.01）. ③ The levels of urinary NGAL and KIM-1 in sepsis group were significantly higher than those in sham group and VNS group（P<0.01）. ④ As compared with those of rats in sham group and VNS group, the renal histological damage score and the renal tubule apoptotic cell coun of rats in sepsis group were significantly increased（P<0.01）. ⑤ Scr, BUN, TNF-α, IL-6, urinary NGAL, urinary KIM-1, 24 h urine volume per kilogram, renal histological damage score, and renal tubule cell apoptosis count in sepsis group showed no significant difference from α7nAChR antagonist group（P>0.05）. Conclusion  Electrical stimulation of vagus nerve can significantly alleviate sepsis-induced acute kidney injury in rats，through the activation of α7nAChR dependent cholinergic anti-inflammatory pathway.
