The Claim
In arterial smooth muscle cells adjacent to oropharyngeal squamous cell carcinoma tumors, protein expression of both the α1- and β1-subunits of soluble guanylyl cyclase is significantly reduced compared to adjacent tumor-free arterial tissue, regardless of HPV status, suggesting impaired nitric oxide signaling may contribute to vascular remodeling in the tumor microenvironment.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Arterial smooth muscle cells near oropharyngeal squamous cell carcinoma tumors show lower levels of α1- and β1-subunit proteins of soluble guanylyl cyclase than nearby healthy arterial tissue, independent of HPV status.

High levels of harmful molecules called reactive oxygen species in the tumor area damage a key protein in blood vessel walls that normally responds to a relaxation signal from nitric oxide. When this protein breaks down, the blood vessels stop responding to the signal and start growing extra layers of cells, forming new arteries that feed the tumor.
What the research says
1 studyNear throat cancer tumors, the blood vessel walls have less of two important proteins that help blood vessels relax. This happens whether the cancer is caused by HPV or not, which may make the blood vessels grow abnormally to feed the tumor.
