How Nitric Oxide Targets Triple-negative Breast Cancer?


Nitric oxide interacts with totally different elements of the massive community of proteins and different molecules that encompass, help, and provides construction to tumor cells and tissues within the physique. Hyaluronic acid is without doubt one of the important elements of this community and is the fabric of selection for fabricating these hydrogels.

“HA plays multiple roles in tumor tissues” says Amir. “However, its interactions with nitric oxide have not been thoroughly investigated. The study, recently published in Biomacromolecules, attempts to understand the mechanism of these interactions and the different effects on nitric oxide levels and migration of breast cancer cells.”


The research is supervised by Prof Abhay Pandit, Scientific Director of CRAM, and was printed with collaborators Dr Sharon Glynn from the Lambe Institute for Translational Analysis and Dr Pau Farras from the Faculty of Organic and Chemical Sciences within the Ryan Institute on the Nationwide College of Eire Galway.

The work investigated the flexibility of HA to scavenge nitric oxide. The crew discovered that the conversion of nitric oxide to sure nitrogen centered free radicals causes the HA to interrupt down, which additional inhibits the nitric oxide induced migration of most cancers cells within the tumor surroundings.

Collectively, these outcomes assist towards understanding the involvement of HA in nitric oxide induced cell migration and suggests the potential use of modified HA, as a key materials in numerous biomedical purposes.

Commenting on the research, Professor Abhay Pandit, stated: “While the recent progress in research about the roles of nitric oxide with tumor progression resulted ultimately in a number of ongoing clinical trials for evaluating the effects of NO-synthase inhibitors, we are focusing on NO itself trying to avoid the side effects/reactions of these inhibitors.”
