WebTumors often show, compared to normal tissues, a markedly decreased extracellular pH resulting from anaerobic or aerobic glycolysis in combination with a reduced removal of acidic metabolites. Several studies indicate that acidosis induces (independently from hypoxia) hematogenous and lymphatic spread of tumor cells worsening the long-term ...

WebThe cellular surface pH values in the centers of HeLa, M4A4, and NM2C5 tumors were found to be 6.5 ± 0.2, 6.7 ± 0.5, and 6.9 ± 0.3, respectively, with some HeLa and M4A4 tumors having regions with surface pH values as low as pH 6.0–6.1. Fig. 3. pH measured at the surfaces of cancer cells in tumors in vivo and ex vivo. WebAug 4, 2024 · The low pH affects cells surrounding the cancer, and tumor acidosis has been shown to inhibit the activity of immune cells. Despite many previous studies, the immune surveillance mechanisms are not fully understood. We found that the expression of PD-L1 was significantly increased under conditions of extracellular acidosis in MDA-MB-231 cells.
