Cerebral cortex protein alterations in response to treatment with GABAAR agonist phenobarbital in infancy

For each altered isoprotein, an abbreviation, the 2-DE spot number, the Swiss-Prot/TrEMBL accession number and/or NCBI reference number, the expression group (S, stable; E, early; L, late; T, transient), the number of peptides identified through ESI-MS, the sequence coverage (Seq. cov.), an ESI-MS identification score, and the percentage of difference of an individual spot between treated mice and controls are presented. For mobility variants (mV), the numbers of mouse pairs showing this alteration are given in parentheses. Triangles pointed upward (▴) and downward (▾) indicate an increase or decrease, respectively, of a spot intensity in treated mice as compared with their control littermates.
