Glutamate receptor subunit 1 (GluR1) is one of the four possible subunits of the AMPA-type glutamate receptor. The integrity of this receptor is crucial for learning processes. However, reductions of GluR1 are noticeable in the hippocampal formation of patients suffering from Alzheimer's disease. Such degradations presumably result in an impaired synaptic(More)
TRPC3 has been suggested as a key component of phospholipase C-dependent Ca(2+) signaling. Here we investigated the role of TRPC3-mediated Na(+) entry as a determinant of plasmalemmal Na(+)/Ca(2+) exchange. Ca(2+) signals generated by TRPC3 overexpression in HEK293 cells were found to be dependent on extracellular Na(+), in that carbachol-stimulated Ca(2+)(More)
Ion channels formed by canonical transient receptor potential (TRPC) proteins are considered to be key players in cellular Ca(2+) homeostasis. As permeation of Ca(2+) through TRPC homo- and/or heteromeric channels has been repeatedly demonstrated, analysis of the physiological role of TRPC proteins was so far based on the concept that these proteins form(More)
Among the myriad of molecular alterations occurring in heart failure development, aggravation of the disease is often attributed to global or local changes in protein kinase activity, thus making protein kinases attractive targets for therapeutic intervention. Since protein kinases do not only have maladaptive roles, but also contribute to the physiological(More)
Recent evidence suggests involvement of transient receptor potential (TRP)-related cation channels in cardiac physiology and pathophysiology, with TRPC3 as one potential key player in cardiac hypertrophy. It has been suggested that TRPC3 is upregulated in hypertrophy development and contributes to Ca 2+ signals that govern pathological remodelling. As TRPC(More)
