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 ... WebThe average pH e in vulvar tumours is 7.26, 0.7 pH unit less than in normal vulvar tissues (with an average pH e of 7.96). 6 Uterine tumour tissues also have a lower average pH e (6.92) than normal uterus, whose average pH e …

WebJan 6, 2024 · In comparison to healthy tissue many tumors show pronounced extracellular acidosis with pH values even below 6.0 [ 1 ]. These adverse environmental conditions result from increased glycolytic metabolism due to an insufficient oxygen supply. Thus, many tumors are characterized by concomitant hypoxia and extracellular acidosis [ 2, 3 ].
