Immunohistochemistry for haptoglobin (Hp) in the postischemic hippocampus demonstrated an immunoreactivity visible one day after reperfusion and continuing to increase until 14 days after ischemia. The immunoreactivity was most prominent in CA1 and the dentate hilar region, especially in cells with astroglial morphology. Double immunofluorescence(More)
The present study investigates the role of small G-proteins of the Ras family in the epidermal growth factor (EGF)-activated cellular signalling pathway that downregulates activity of the epithelial Na+ channel (ENaC). We found that H-Ras is a key component of this EGF-activated cellular signalling mechanism in M1 mouse collecting duct cells. Expression of(More)
