Detecting splice variants in mammary tumor and mammary gland samples. a Splice variants missing exons 14-16 were detected in mammary tumor samples. The left panel shows the PCR products detected by 1 % agarose gel electrophoresis, and the right panel shows the DNA sequence chromatogram. b Splice variant missing exons 12 and 14 were detected in mammary tumor samples. The left panel shows the PCR products detected by 1 % agarose gel electrophoresis, and the right panel shows the DNA sequence chromatogram. c Splice variants detected in mammary gland samples. Symbols are as follows: *, splice variant missing exon 12; §, splice variant missing exon 14; #, splice variant missing exons 13-16
