Positive correlation between the expression of hEag1 and HIF-1α in breast cancers: an observational study
OBJECTIVES: To explore the expression patterns of Eag1 (ether á go-go 1) and HIF-1α (hypoxia-inducible factor 1α) in a cohort of patients with breast cancer. SETTING: Department of general surgery in an upper first-class hospital in Xi'an, China. PARTICIPANTS: A total of 112 female Han Chinese...

Sumario: | OBJECTIVES: To explore the expression patterns of Eag1 (ether á go-go 1) and HIF-1α (hypoxia-inducible factor 1α) in a cohort of patients with breast cancer. SETTING: Department of general surgery in an upper first-class hospital in Xi'an, China. PARTICIPANTS: A total of 112 female Han Chinese patients with a diagnosis of invasive ductal carcinoma were included. Patients with main internal diseases, such as cardiovascular, endocrine, gastroenterological, haematological, infectious diseases, etc, were excluded. PRIMARY AND SECONDARY OUTCOME MEASURES: Expression profiles of Eag1 and HIF-1α. RESULTS: Eag1 and HIF-1α were overexpressed in the tumour tissues compared with the pair-matched control tissues, p=0.002 and <0.001, respectively. The expression of Eag1 and HIF-1α was negatively correlated with tumour size, p=0.032 and p=0.025, respectively, and lymph node status (p=0.040, p=0.032, respectively). The coexpression of Eag1 and HIF-1α was correlated with tumour size (p=0.012), lymph node status (p=0.027) and tumour stage (p=0.036). HIF-1α has a strong correlation with hEag1 expression (κ=0.731, p<0.001). CONCLUSIONS: HIF-1α expression has a strong correlation with hEag1 expression. We are the first to attempt to explore the correlation at the population level. |
