Tumor pH and metastasis: a malignant process beyond hypoxia
WebAs the tumor mass increases, the interior of the tumor becomes farther away from existing blood supply. While angiogenesis can reduce this effect, the partial pressure of oxygen is below 5 mm Hg (venous blood has a partial pressure of oxygen at 40 mm Hg) in more than 50% of locally advanced solid tumors. WebAug 29, 2024 · Due to the reprogramming of metabolism in such conditions and the use of glycolysis as a major source of ATP production, tumor cells have an acidic pHe (6.4-7.1) and an alkaline pHi (7.1-7.8). For normal tissues, the pHe is around 7.4, and the pHi is around 7.2 ( … WebMar 14, 2016 · Tumor-derived acidity is also hypothesized to suppress immune function . For example, lactic acidosis is a strong negative prognostic indicator in sepsis . In vitro, acidic pH (6.5) can suppress T-cell functions, including IL2 secretion and the activation of T-cell receptors , although the mechanism by which this occurs is not known. little big town welcome to the family
