WebMy advisor recently told me I have to publish 4 high-quality papers to graduate. It really shocked me, and made me feel that my PhD program is a tumor. I’m in a mental state that I cry everyday for 2 hours. I persisted so far because I was promised a $50k postdoc position with my previous advisor in my home country. 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.
