The ChIP assay demonstrated that CIC physically binds to the promoter region of FOLR1, PCFT and RFC1. Compared with IgG control antibody, CIC antibody enriched 4.1-fold more targeted FOLR1 promoter DNA, 13.8-fold more targeted PCFT promoter DNA and 4.2-fold more targeted RFC1 promoter DNA (figure 3B).
As far as I understand, the authors used chromatin immunoprecipitation to look whether and to what extent the CIC gene influences the promoters of folate-related genes (FOLR1, PCFT, and RFC1). And well enough, they discovered that the antibody to CIC precipitates more "promoter sequences" compared with the control antibody (IgG).
What does the word "targeted" mean here? If I remove this word, the meaning seems unaffected to me. In my Russian translation, I just omitted this word, because it does not seem to bear any additional meaning, but I'm not sure.
Can one simply omit "targeted" or does it have a meaning?
