“…The first group of genes (Table 2), which was examined using real-time PCR, includes Bdnf, nuclear receptor subfamily 3 group C member 1 (Nr3c1), Esr1, insulin-like growth factor I receptor (Igfr1), and olfactory factor 522 (Olr522). The genes were chosen based on data published by various scientific groups (Middaugh, 1989; Cernerud et al, 1996; Wouldes et al, 2004; Šlamberová and Rokyta, 2005; Chang et al, 2007; Ago et al, 2009; Schutová et al, 2008, 2009, 2012; Lloyd et al, 2013; Macúchová et al, 2013, 2014; Leung et al, 2014; Šlamberová et al, 2014; Ren et al, 2016, 2017). The second group of genes (Table 3), which was examined using real-time PCR, includes Tacr3, dopamine receptor D3 (Drd3), Cartpt, Rps6ka a Foxp2 genes.…”
