From: Regulation of Kir4.1 expression in astrocytes and astrocytic tumors: a role for interleukin-1 β

IR score A II(n = 6) A III(n = 12) GBM (n = 55 ) Control cortex/autopsy (n = 8) Control cortex/surgical (n = 5)
Kir4.1 3.6 ± 0.85* 7.18 ± 0.41 5.5 ± 0.30 7.13 ± 0.36 7.03 ± 0.26
IL-1β 2.46 ± 0.67* 3.9 ± 0.9* 3.75 ± 0.45* 0 0.02 ± 0.02
HLA-DR 5.4 ± 0.77* 5.7 ± 0.80* 5.83 ± 0.35* 0.04 ± 0.02 0.03 ± 0.02
  1. A II, Astrocytoma WHO grade II; A III, Astrocytoma WHO grade III; GBM, Glioblastoma multiforme.
  2. Values represent the average immunoreactive score (IR) ± SEM. *P <0.05 (compared to control cortex, both autopsy and surgical samples). Kir4.1 IR score for AIII > Kir4.1 score for AII (P <0.05).
