A bibliometric analysis of apoptosis in glaucoma.

Background: Glaucoma is the first irreversible and second blindness disease, which is characterized by the death of retinal ganglion cells (RGCs) and degeneration of the optic nerve. Previous works have indicated that apoptosis is the main reason for RGC death in glaucoma. Although many studies have investigated the mechanism of apoptosis and different strategies targeting apoptosis to protect the RGCs and finally recover the impaired vision in the glaucoma. However, the global trend and hotspots of apoptosis in glaucoma have not been well illustrated and discussed. Methods: Documents were extracted from the Web of Science Core Collection on November 2, 2022. We selected articles and reviews published in English from January 1, 1999 to November 1, 2022 to perform visual analysis and statistical analysis of countries, institutions, authors, references and keywords by VOSviewer 1.6.18 and CiteSpace 5.8. Results: The publications about apoptosis in glaucoma show an increasing trend over time. Besides, the authors, institutions in the US and China published the most numbers of articles with the highest citation, which may be leading the research in the field of apoptosis in glaucoma. Last, series of advanced research results, technology and treatment for glaucoma, such as the discovery of key regulatory mechanisms on RGC apoptosis are emerging and will provide precise strategies for the treatment of glaucoma. Conclusion: This research will broaden our comprehension about the role of apoptosis in the process of glaucoma, and provide guidelines for us in basic research and disease treatment in the further.

A bibliometric analysis of PIN1 and cell death.

Background: Regulation of cell death plays a key role in numerous diseases. As a proline isomerase, prolyl cis-trans isomerase NIMA-interacting 1 (Pin1) is important for the regulation of signaling pathways. An in-depth understanding of how Pin1 participates in the process of cell death, which affects the occurrence and development of diseases, will aid in the discovery of new disease mechanisms and therapeutic methods. Thus, the purpose of our study was to discover the research trends and hotspots of Pin1 and cell death through bibliometric analyses and to provide insights for understanding the future development of basic research and treatment of diseases. Methods: Documents were extracted from the Web of Science Core Collection on 7 May 2022. We selected articles and reviews published in English from 2000 to 2021, and visual and statistical analyses of countries, institutions, authors, references and keywords were performed using VOSviewer 1.6.18 and CiteSpace 5.8. Results: A total of 395 articles and reviews were selected. Since 2001, the number of articles on Pin1 and cell death has increased annually. Publications come from 43 countries, with the US having the most publications and citations. We identified 510 authors, with Giannino Del Sal having the most articles and Paola Zacchi having the most co-citations. The Journal of Biological Chemistry is the most researched journal, and Nature and its subjournals are the most cited journals. Apoptosis, phosphorylation, and breast cancer were the three most common keywords. Conclusion: The number of documents showed an increasing trend from 2001 to 2014. Stagnant growth after 2014 may be related to the absence of new research hotspots. Cooperative links between core institutions need to be strengthened, and the institution with the highest citation count in recent years is Fujian Medical University in China. The role of Pin1 in cell death requires further research to discover new research hotspots. Before breakthroughs in molecular mechanism or signaling pathway research, future research will focus more on the treatment of diseases represented by Pin1 inhibitors.

Cobalt(II)-Catalyzed Decarboxylative C-H Activation/Annulation Cascades: Regioselective Access to Isoquinolones and Isoindolinones.

A new cobalt(II)-catalyzed decarboxylative C-H activation/annulation of benzamides and alkynyl carboxylic acids has been described. Alkynyl carboxylic acids were first employed as the coupling partners using inexpensive Co(OAc)2·4H2O as the catalyst. This method enables a switchable cyclization to isoquinolones and isoindolinones with excellent selectivity. Moreover, a catalytic amount of Ag2O was adopted as co-catalyst and O2 (from air) as a terminal oxidant for the preparation of isoquinolones.

TPX2 promotes migration and invasion of human breast cancer cells.

OBJECTIVE: To investigate the expression of targeting protein for Xenopus kinesin-like protein 2 (TPX2) in breast cancer tissue and to explore its role in proliferation, migration and invasion of breast cancer cells. METHODS: The mRNA and protein expressions of TPX2 in breast cancer tissue and cell lines were assessed by quantitative RT-PCR and Western blot. The effect of TPX2 with RNA interference on proliferation, invasion and migration of breast cancer cells was observed by MTT and Transwell assays. RESULTS: Both mRNA and protein expressions of TPX2 were upregulated in breast cancer tissues compared to tumor-adjacent tissue. TPX2 expression was also upregulated in breast cancer cell lines, and the TPX2 interfered by small interfering RNA could inhibit the proliferation, invasion and migration of breast cancer cells by inhibiting matrix metalloproteinase-2 and matrix metalloproteinase-9. CONCLUSIONS: Significantly upregulated TPX2 expression is observed in breast cancer tissue and cells, and contributes to promote the proliferation, migration and invasion of breast cancer cells.

Diagnosis and treatment of Paget's disease of the breast: an analysis of 72 cases.

OBJECTIVE: Clinical features, prognostic factors and principle of surgical treatment for Paget's disease of the breast were analyzed, so as to optimize the treatment of Pagent's disease of the breast. METHOD: Seventy-two cases of Paget's disease of the breast treated at Affiliated Union Hospital and Hospital of Integrated Traditional Chinese and Western Medicine, Huazhong University of Science and Technology, from January 1991 to January 2010 were recruited. Their clinical data were analyzed retrospectively. RESULTS: Among 72 cases, 52 cases had nipple-areolar complex lesions, 43 had palpable masses and 18 had palpable, enlarged axillary lymph nodes; 45 cases received radical mastectomy or modified radical mastectomy. Intraoperative pathological examination was performed for 9 cases who were not discovered to have breast lumps or enlarged axillary lymph nodes preoperatively; and 4 of them were diagnosed as lower axillary lymph node metastasis or invasive ductal carcinoma, and modified radical mastectomy was adopted for these cases. Fifty-two cases received postoperative pathological examination to reveal that the average number of metastatic lymph nodes was 3.1. Among the cases presenting with lymph node metastases, those negative for ER/PR accounted for 78%; Her-2-positive cases accounted for 56%. Thirty-seven cases were followed up for an average of 29 months postoperatively, and 5 of them were found with local recurrence and 7 with distant metastases. CONCLUSION: Most cases of Paget's disease of the breast were associated with invasive ductal carcinoma and lymph node metastases. These cases had low ER/PR positive rate, high Her-2 positive rate and poor prognosis.
