This research aimed to examine the levels of CIRBP and HIF1α mRNA within breast tumor tissues and explore the relationship between their gene expression and tumor Microvascular density (MVD) .  \nResults The results revealed a significant upregulation of CIRBP (5 . 07-fold) and HIF1α (4 . 5-fold) gene expression in BC samples compared to the surrounding normal tissues (p \u003C 0. 001) . This upregulation was also associated with various clinicopathologic features. Furthermore, there was a correlation between CIRBP mRNA expression, HIF1α mRNA expression, and MVD. Consequently, this study suggests that CIRBP may have a role in promoting angiogenesis in BC. Keywords Breast cancer, Microvascular density, Gene expression  \nIntroduction  \nBreast cancer (BC) is currently considered the most common cancer in women, with 23.6 new cases per 100,000 [1]. In recent times, a multitude of research endeavors have been undertaken to pinpoint novel biomarkers facilitating early detection and treatment monitoring in BC [2–4]. Therefore, a deeper understanding of the fundamental mechanisms at play in BC can significantly contribute to the discovery of these new biomarkers.  \n*Correspondence:  \nMaryam Adelipour  \n[adelimaryam@rocketmail.com](adelimaryam@rocketmail.com); [adelipour-m@ajums.ac.ir](adelipour-m@ajums.ac.ir)[ ](adelipour-m@ajums.ac.ir)1Department of Biochemistry, School of Medicine, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran  \n2Department of Pathology, School of Medicine, Cancer Institute, Tehran University of Medical Science, Tehran, Iran  \n3Department of Biostatistics and Epidemiology, School of Health, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran  \n4Cellular and molecular research center, Medical Basic Science Research Institute, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran  \nAngiogenesis, the formation of new blood vessels, is crucial for tumor growth and metastasis. Normally, it is regulated by a balance of pro-angiogenic and anti-angiogenic factors. In cancer, this balance is disrupted, leading to new blood vessel formation [5, 6]. Studies has shown that hypoxia-inducible factor 1α (HIF-1α) can directly stimulate the expression of specific angiogenic factors, such as vascular endothelial growth factor (VEGF), thus facilitating the formation of new blood vessels [7]. Notably, local hypoxia is known to occur during the early stages of BC development. In hypoxic conditions, there is a potential elevation in HIF-1α expression within tumor cells, subsequently promoting VEGF-induced angiogenesis [5]. It is important to emphasize the role of local hypoxia during the initial phases of breast cancer development, as it fosters a microenvironment that supports the upregulation of HIF1α and the subsequent induction of VEGF-mediated angiogenesis, which, in turn, drives tumor advancement, invasion, and metastasis [8].  \n© The Author(s) 2025.
