The paracrine effect of normoxic and hypoxic cancer secretions on blood-brain barrier endothelial cells

Abstract

Cancer is the most common leading cause of death worldwide. Glioblastoma and breast cancer are the most aggressive solid tumour. The survival rate of these tumours depends on their ability to progress and spread. These cancers use their high proliferative capabilities for survival, increasing their malignancies. Glioblastoma is considered the most aggressive tumour initiated in the brain, whereas breast cancer is the most common metastatic cancer in the brain, both types of cancer are known as high infiltrated cancer and their invasiveness due to their capability to release factors that can alter the neighbouring cells to facilitate their progression.
