Project description:Background: Podocyte injury has a direct causal relationship with proteinuria and glomerulosclerosis and, on a chronic level, can lead to irreversible disease progression. Podocyte injury plays a critically decisive role in the development of proteinuric kidney disease. In recent years, the research on podocyte injury has developed rapidly all over the world. However, no report has summarized the field of podocyte injury as a whole to date. Using bibliometric analysis, this study aimed to evaluate the current state of worldwide podocyte injury research in the last 30 years and identify important achievements, primary research fields, and emerging trends. Methods: Publications related to podocyte injury were retrieved from Web of Science Core Collection. HistCite, VOSviewer, CiteSpace, and the Bibliometrix Package were used for bibliometric analysis and visualization, including the analysis of the overall distribution of annual outputs, leading countries, active institutions and authors, core journals, co-cited references, and keywords. Total global citation score and total local citation score were used to assess the quality and impact of publications. Results: A total of 2,669 publications related to podocyte injury were identified. Publications related to podocyte injury tended to increase continuously. A total of 10,328 authors from 2,171 institutions in 69 countries published studies related to podocyte injury. China (39.46%) was the most prolific country, and the number of citations of studies in the United States (cited 36,896 times) ranked first. Moin A Saleem, John Cijiang He, and Zhihong Liu were the top three contributing authors, and Journal of the American Society of Nephrology and Kidney International were the most popular journals in the field. "Diabetic nephropathy" is the primary focus area of podocyte injury research, and "autophagy," "microRNA," and "inflammation" were the top keywords of emerging research hotspots, and traditional Chinese medicine monomer may be a neglected research gap.

Project description:Background Necroptosis, a recently discovered programmed cell death, has been pathologically linked to various diseases and is thus a promising target for treating diseases. However, a comprehensive and objective report on the current status of entire necroptosis research is lacking. Therefore, this study aims to conduct a bibliometric analysis to quantify and identify the status quo and trending issues of necroptosis research in the last decade. Methods Articles were acquired from the Web of Science Core Collection database. We used two bibliometric tools (CiteSpace and VOSviewer) to quantify and identify the individual impact and cooperation information by analyzing annual publications, journals, co-cited journals, countries/regions, institutions, authors, and co-cited authors. Afterwards, we identified the trending research areas of necroptosis by analyzing the co-occurrence and burst of keywords and co-cited references. Results From 2012 to 2021, a total of 3,111 research articles on necroptosis were published in 786 academic journals by 19,687 authors in 885 institutions from 82 countries/regions. The majority of publications were from China and the United States, of which the United States maintained the dominant position in necroptosis research; meanwhile, the Chinese Academy of Sciences and Ghent University were the most active institutions. Peter Vandenabeele published the most papers, while Alexei Degterev had the most co-citations. Cell Death & Disease published the most papers on necroptosis, while Cell was the top 1 co-cited journal, and the major area of these publications was molecular, biology, and immunology. High-frequency keywords mainly included those that are molecularly related (MLKL, TNF-alpha, NF-κB, RIPK3, RIPK1), pathological process related (cell-death, apoptosis, necroptosis, necrosis, inflammation), and disease related (cancer, ischemia/reperfusion injury, infection, carcinoma, Alzheimer’s disease). Conclusion Necroptosis research had a stable stepwise growth in the past decade. Current necroptosis studies focused on its cross-talk with other types of cell death, potential applications in disease treatment, and further mechanisms. Among them, the synergy with ferroptosis, further RIPK1/RIPK3/MLKL studies, its association with inflammation and oxidative stress and translational applications, and the therapeutic potential to treat cancer and neurodegenerative diseases are the trending research area. These might provide ideas for further research in the necroptosis field.

Project description:BackgroundAtherosclerosis (AS) is closely related to stroke and cardiovascular diseases. Nuclear factor kappa-B (NF-κB) is the master regulator of inflammation, and thus, modulating the transcription of NF-κB can improve AS.MethodsIn this study, we conducted a bibliometric analysis to identify the frontiers, hotspots, and features of global research output on NF-κB in AS from 2000 to 2021. Papers published from 2000 to 2021 and the recorded information were retrieved from the Science Citation Index-Expanded of the Web of Science Core Collection. Bibliometric analysis and visualization were performed using VOSviewer and CiteSpace, including an analysis of the general distribution of annual output, highly productive countries, active journals, active institutions and authors, keywords, and co-cited references.ResultsA total of 5,439 original articles and reviews were retrieved and analyzed, and the results indicated that the annual number of publications on NF-κB in AS has been increasing in waves over the past 22 years. The majority of papers were published in China, while the USA had the highest number of citations and H-index. The most productive affiliation and journal were the University of California System and Arteriosclerosis Thrombosis and Vascular Biology, respectively. The papers of Chiu JJ. received the highest number of citations globally in 2011. The keywords, "nlrp3 inflammasome" and "microRNA", have recently attracted considerable attention, and very frequently occurring keywords included "NF kappa B", "atherosclerosis", "expression", "activation", "endogenous cell", and "oxidative stress". New keywords in 2021 included "muscle", "attenuates atherosclerosis", "mesenchymal transition", "metabolic disorder", and "palmitic acid".ConclusionsAS and inflammation have become research hotspots lately. Over the past decade, most studies have focused on basic research, and pathways associated with the regulatory role of NF-κB in AS have become a particular focus in recent studies. Moreover, our study revealed that NF-κB plays a remarkable role in AS and may be a therapeutic target.
