To further confirm that total p‐Tau levels increase in NA‐GBM samples we performed western blot analysis and found a significant increase (p = 0.0286) in p‐Tau in NA‐GBM samples compared to control samples, as well as an expected increase of p‐Tau in the AD samples (Figure 4e,f). The gene discussed is MAPT; the disease is Alzheimer disease.
