Semiquantitative analysis of human BDNF, antiBDNF, and control GAPDH mRNA expression by RT-PCR in different human brain regions. Roman numerals on the left indicate the detected BDNF transcripts and the 5′-exon-specific primers used in combination with an antisense primer located in the BDNF coding region in exon IXd (Supplementary Table 1). A, C, and G refer to the respective antiBDNF transcripts shown in Fig. 1.
