Comparative characterisation of an ecto-5′-nucleotidase (CD73) in non-tumoral MCF10-A breast cells and triple-negative MDA-MB-231 breast cancer cells
Ecto-5′-nucleotidase (CD73) hydrolyses 5′AMP to adenosine and inorganic phosphate. Breast cancer cells (MDA-MB-231) express high CD73 levels, and this enzyme has been found to play a tumour-promoting role in breast cancer. However, no studies have sought to investigate whether CD73 has differential affinity or substrate preferences between noncancerous and cancerous breast cells. In the present study, we aimed to biochemically characterise ecto-5′-nucleotidase in breast cancer cell lines and assess whether its catalytic function and tumour progression are correlated in breast cancer cells. The results showed that compared to nontumoral breast MCF-10A cells, triple-negative breast cancer MDA-MB-231 cells had a higher ecto-5′-nucleotidase expression level and enzymatic activity. Although ecto-5′-nucleotidase activity in the MDA-MB-231 cell line showed no selectivity among monophosphorylated substrates, 5′AMP was preferred by the MCF-10A cell line. Compared to the MCF-10A cell line, the MDA-MB-231 cell line has better hydrolytic ability, lower substrate affinity, and high inhibitory potential after treatment with a specific CD73 inhibitor α,β‑methylene ADP (APCP). Therefore, we demonstrated that a specific inhibitor of the ecto-5-nucleotidase significantly reduced the migratory and invasive capacity of MDA-MB-231 cells, suggesting that ecto-5-nucleotidase activity might play an important role in metastatic progression.
期刊介绍:
Each month, the journal publishes easy-to-assimilate, up-to-the minute reports of experimental findings by researchers using a wide range of the latest techniques. Promoting the aims of cell biologists worldwide, papers reporting on structure and function - especially where they relate to the physiology of the whole cell - are strongly encouraged. Molecular biology is welcome, as long as articles report findings that are seen in the wider context of cell biology. In covering all areas of the cell, the journal is both appealing and accessible to a broad audience. Authors whose papers do not appeal to cell biologists in general because their topic is too specialized (e.g. infectious microbes, protozoology) are recommended to send them to more relevant journals. Papers reporting whole animal studies or work more suited to a medical journal, e.g. histopathological studies or clinical immunology, are unlikely to be accepted, unless they are fully focused on some important cellular aspect.
These last remarks extend particularly to papers on cancer. Unless firmly based on some deeper cellular or molecular biological principle, papers that are highly specialized in this field, with limited appeal to cell biologists at large, should be directed towards journals devoted to cancer, there being very many from which to choose.
