Wnt signaling in liver disease: emerging trends from a bibliometric perspective

Global current research status and future hotspots in osteoporotic fracture based on bibliometric assessment and visualization techniques

BACKGROUND

In the past decade, the evolution of themes in the field of osteoporotic fractures has changed from epidemiology and prediction of long-term morbidity, risk assessment of osteoporotic fractures, and zoledronic acid and denosumab in the treatment of osteoporosis to treatment guidelines for osteoporosis and the side effects caused by anti-osteoporotic drugs.

AIM

To understand the trends and hotspots in osteoporotic fracture research.

METHODS

Original articles were retrieved between January 1, 2010, and December 31, 2019, from the Web of Science Core Collection database. CiteSpace software facilitated the analysis and visualization of scientific productivity and emerging trends.

RESULTS

Nine studies were identified using bibliometric indices, including citation, centrality, and sigma value, which might indicate a growing trend. Through clustering, we identified six major hot subtopics. Using burst analysis, top-5 references with the strongest bursting strength after 2017 were identified, indicating a future hotspot in this field.

CONCLUSION

Current hot subtopics in osteoporotic fracture research include atypical femoral fractures, androgen deprivation therapy, denosumab discontinuation, hip fractures, trabecular bone score (TBS), and bone phenotype. Management and prevention of secondary fractures in patients with osteoporotic fractures, TBSs, and long-term administration strategy for zoledronic acid are expected to become research hotspots.

Exploring the Impact of the β-Catenin Mutations in Hepatocellular Carcinoma: An In-Depth Review

Liver cancer, primarily hepatocellular carcinoma, represents a major global health issue with significant clinical, economic, and psychological impacts. Its incidence continues to rise, driven by risk factors such as hepatitis B and C infections, nonalcoholic steatohepatitis, and various environmental influences. The Wnt/β-Catenin signaling pathway, frequently dysregulated in HCC, emerges as a promising therapeutic target. Critical genetic alterations, particularly in the CTNNB1 gene, involve mutations at key phosphorylation sites on β-catenin's N-terminal domain (S33, S37, T41, and S45) and in armadillo repeat domains (K335I and N387 K). These mutations impede β-catenin degradation, enhancing its oncogenic potential. In addition to genetic alterations, molecular and epigenetic mechanisms, including DNA methylation, histone modifications, and noncoding RNAs, further influence β-catenin signaling and tumor progression. However, β-catenin activation alone is insufficient for hepatocarcinogenesis; additional genetic "hits" are required for tumor initiation. Mutations or alterations in genes such as Ras, c-Met, NRF2, and LKB1, when combined with β-catenin activation, significantly contribute to HCC development and progression. Understanding these cooperative mutations provides crucial insights into the disease and reveals potential therapeutic strategies. The complex interplay between genetic variations and the tumor microenvironment, coupled with novel therapeutic approaches targeting the Wnt/β-Catenin pathway, offers promise for improved treatment of HCC. Despite advances, translating preclinical findings into clinical practice remains a challenge. Future research should focus on elucidating how specific β-catenin mutations and additional genetic alterations contribute to HCC pathogenesis, leveraging genetically clengineered mouse models to explore distinct signaling impacts, and identifying downstream targets. Relevant clinical trials will be essential for advancing personalized therapies and enhancing patient outcomes. This review provides a comprehensive analysis of β-Catenin signaling in HCC, highlighting its role in pathogenesis, diagnosis, and therapeutic targeting, and identifies key research directions to improve understanding and clinical outcomes.

Methods: All relevant articles and reviews from 1993 to 2022 were collected from the Web of Science Core Collection (WoSCC). Bibliometric analysis and visualization were performed using CiteSpace 6.1 R3, VOSviewer 1.6.15, and the Online Analysis Platform of Literature Metrology (http://bibliometric.com/). Results: A total of 7,184 papers were retrieved, authored by 28,443 researchers from 89 countries/regions and published in 261 academic journals. The annual publication numbers peaked in 2021. China and United States are the leading countries, with the University of California and Harvard University as the most active institutions. Wang, Yang is the most prolific author. Bone has the most published research, while Proceedings of the National Academy of Sciences of the United States is the most cited journal on average. The main keywords include expression, Wnt, osteoporosis, bone, and osteogenic differentiation. Current and developing research hotspots focus on bone mass, sclerostin antibody, multiple myeloma, and cartilage development. Conclusion: This paper provides new insights for researchers to delve into the mechanisms of Wnt and bone related diseases and translate into clinical studies. It reveals the development and future research trends in Wnt and skeletal-related studies.

Ferroptosis synergistically sensitizes wee1 inhibitors: a bibliometric study

Synthetic lethality (SL) is a lethal phenomenon with an important role in cancer treatment. This study was conducted to analyze the hotspots and frontiers in SL research. The Web of Science Core Collection (WOSCC) was used to identify the 100 top-cited articles related to SL research. Additionally, wee1 inhibitors combined with erastin were used to determine the effectiveness of SL in vitro and in vivo. Relevant articles were published mainly from 2009 to 2021, reaching a peak in 2020; articles published in 2010 were most frequently cited among the 100-top cited papers. Most studies (54%) were performed in the United States. Articles in Nature Chemical Biology were cited more frequently than articles in other journals, whereas Nature published the largest number of reports on SL. Among the 88 corresponding authors, CJ Lord was the most productive. Overlay visualization of keyword analysis revealed that the hotspots in SL research were PARP inhibitors, BRCA mutations, DNA damage repair, and carcinogenesis. CRISPR, ferroptosis, wee1, double-strand break (dsb) repair, myc, immunotherapy, and replication stress are emerging topics in SL research, whereas ovarian cancer, prostate stress, acute myeloid leukemia, and other topics have been used as disease models in recent years. The application and therapeutic strategy of SL in cancer is an emerging trend. Significantly, experiments verified that the wee1 inhibitor AZD1775 and ferroptosis activator erastin have synergistic effects on ovarian cancer in vitro and in vivo. Combining bibliometric analysis with experimental verification is a useful approach for SL research.
