Ph of tumor

WebTo maintain an intracellular pH (pHi) that is slightly alkaline (~pH 7.4), tumor cells upregulate several proton extrusion mechanisms such as the Na + /H + Exchanger (NHE), HCO3 − Transporter, Carbonic Anhydrase IX, Vacuolar-ATPase, and the H + /K + ATPase. Excess protons are excreted into the extracellular matrix, causing the pHe of the ...

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. WebThe acidic microenvironment of melanoma and most human cancers is an indication of disease progression. 21,22 While normal cells tend to have an extracellular pH of 7.4, the acidic tumor microenvironment has a pH between 5.5 to 7.4. 23,24 To provide controlled anti-cancer drug release in response to changing pH in the tumor region, a pH ...
