Background: Extracellular signal-regulated kinase (ERK) cascades are key signaling pathways involved in regulation of normal cell proliferation, survival and differentiation. Abberrant regulation of the ERK pathway contributes to tumourigenesis. The ERK signalling cascade partially controls transcription of the cell cycle regulator cyclin D1 and also expression and protein stability of the c-Myc proto-oncogene.Methods: Western Blotting was used to invest...

We have recently reported that cannabinoids can stimulate hypothalamic and heart AMPK activity and can inhibit liver and adipose tissue AMPK activity in rats (Kola et al., JBC, 2005). These data are in accordance with the known orexigenic and adipogenic cannabinoid effects and also with their beneficial effects on the ischaemic heart. We have studied the effects of cannabinoids on AMPK activity in tissues from wild type (WT) and CB1 knockout (KO) mice to see if the CB1 ...
