AbstractRecently, a strong correlation between metabolic disorders, tumor onset, and progression has been demonstrated, directing new therapeutic strategies on metabolic targets. OLR1 gene encodes the LOX-1 receptor protein, responsible for the recognition, binding, and internalization of ox-LDL. In the past, several studied, aimed to clarify the role of LOX-1 receptor in atherosclerosis, shed light on its role in the stimulation of the expression of adhesion molecules, pro-inflammatory signaling pathways, and pro-angiogenic proteins, including NF-kB and VEGF, in vascular endothelial cells and macrophages. In recent years, LOX-1 upregulation in different tumors evidenced its involvement in cancer onset, progression and metastasis. In this review, we outline the role of LOX-1 in tumor spreading and metastasis, evidencing its function in VEGF induction, HIF-1alpha activation, and MMP-9/MMP-2 expression, pushing up the neoangiogenic and the epithelial–mesenchymal transition process in glioblastoma, osteosarcoma prostate, colon, breast, lung, and pancreatic tumors. Moreover, our studies contributed to evidence its role in interacting with WNT/APC/β-catenin axis, highlighting new pathways in sporadic colon cancer onset. The application of volatilome analysis in high expressing LOX-1 tumor-bearing mice correlates with the tumor evolution, suggesting a closed link between LOX-1 upregulation and metabolic changes in individual volatile compounds and thus providing a viable method for a simple, non-invasive alternative monitoring of tumor progression. These findings underline the role of LOX-1 as regulator of tumor progression, migration, invasion, metastasis formation, and tumor-related neo-angiogenesis, proposing this receptor as a promising therapeutic target and thus enhancing current antineoplastic strategies.

Summary Objective: There have been many studies on adenomyosis, which can impair the quality of life of a woman. There are various kinds of opinions on the pathogenesis, diagnostics and treatment of adenomyosis. The goal of this article is to present the current knowledge of adenomyosis and its impact on the endometrial function and receptivity. Methods: PubMed/Medline, Web of Sciences and Scopus were searched for the articles in English indexed until February 2021 with terms of: adenomyosis, endometrial receptivity, and infertility. Results: Recent studies on angiogenesis and epithelial-mesenchymal transition in the endometrium bring new information on the ethiology and pathogenesis of adenomyosis. In clinical practice, the main diagnostic methods of adenomyosis include transvaginal ultrasound, magnetic resonance imaging or hysteroscopy, although the definitive confirmation is set by histopathological examination. The rules of #Enzian classification of endometriosis should be applied for the classification of adenomyosis. The treatment of adenomyosis should consider individual clinical presentation and reproductive plans of a patient and should be performed in centers for the treatment of endometriosis. Conclusion: Adenomyosis affects endometrial vascularisation and epithelial-mesenchymal transition/mesenchymal-epithelial transition; thus, it can be the cause of irregular uterine bleeding or embryo implantation failure. The research and analysis of endometrial proteome could lead to the new ways of adenomyosis treatment.

The epithelial-mesenchymal transition (EMT) is a complex transformation process that induces local and distant progression of many malignant tumours. Due to its complex array of proteins that are dynamically over-/underexpressed during this process, proteomic technologies gained their place in the EMT research in the last years. Proteomics has identified new molecular pathways of this process and brought important insights to develop new therapy targets. Various proteomic tools and multiple combinations were developed in this area. Out of the proteomic technology armentarium, mass spectrometry and array technologies are the most used approaches. The main characteristics of the proteomic technology used in this domain are high throughput and detection of minute concentration in small samples. We present herein, using various proteomic technologies, the identification in cancer cell lines and in tumour tissue EMT-related proteins, proteins that are involved in the activation of different cellular pathways. Proteomics has brought besides standard EMT markers (e.g., cell-cell adhesion proteins and transcription factors) other future potential markers for improving diagnosis, monitoring evolution, and developing new therapy targets. Future will increase the proteomic role in clinical investigation and validation of EMT-related biomarkers.
