Three gene-specific probe sets (Gad1, Vsx2, and Grm6) were hybridized to dissociated mouse retinal cells, and fluorescent oligos were hybridized only to Gad1 and Vsx2 probe sets to detect subsets of ACs (Gad1+; 3.54%) and BC/MG (Vsx2+; 11.9%). This evidence concerns the gene GRM6 and breast cancer.
