Increasing Tumor Extracellular pH by an Oral Alkalinizing Agent Improves Antitumor Responses of Anti-PD-1 Antibody: Implication of Relationships between Serum Bicarbonate Concentrations, Urinary pH, and Therapeutic Outcomes

چکیده
Acidic extracellular pH (pHe) is characteristic of the tumor microenvironment. Several reports suggest that increasing pHe improves response immune checkpoint inhibitors in murine models. To increase pHe, either sodium bicarbonate (NaHCO3) or citric acid/potassium-sodium citrate (KNa-cit) was chronically administered to mice. It hypothesized ions (HCO3−), produced from these alkalinizing agents vivo, increased tumor, and excess HCO3− eliminated into urine urinary values. However, there little published information on effect changing serum concentrations, concentrations values therapeutic outcomes immunotherapy. In this study, we report oral administration NaHCO3 KNa-cit responses anti-programmed cell death-1 (PD-1) antibody, an inhibitor, a B16 melanoma model. addition, daily agent blood corresponding pHe. Serum also correlated with There clear relationship between antitumor effects immunotherapy anti-PD-1 antibody. Our results imply values, may be important factors predict clinical immunotherapeutic agent, when combined such as KNa-cit.

phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...

متن کاملDexamethasone lowers cytosolic pH in macrophages by altering alkalinizing pH-regulatory mechanisms.
The effect of dexamethasone on cytosolic pH (pHc) in resident mouse peritoneal macrophages was investigated using the fluorescent probe 2',7'-bis(carboxyethyl)-5(6)-carboxyfluorescein tetra-acetoxymethyl ester (BCECF-AM). Dexamethasone was found to significantly lower pHc and this reduction of pHc evolved gradually with time, was near maximal at 10 nM dexamethasone, and could be prevented by th...
