Detection of Group I (mGluR1 and mGluR5) metabotropic glutamate receptor mRNAs in hypothalamic astrocytes (HA) cultured in astrocyte-defined medium (ADM) or serum-containing medium (SCM), as assessed by RNase protection assay. Note that only mGluR5 mRNA is expressed in these cells.M, RNA molecular markers; UP, undigested probe; DP, digested probe; cyclo, cyclophilin mRNA; L, liver; Hc, hippocampus; ID, incomplete digestion.
