GH1 and cancer: Low incidence of cancer in bats, especially in the Myotis, might involve bat‐specific regulatory activities of microRNAs that function tumorigenesis pathways (Huang et al., 2016, 2019), downregulation of the growth hormone/insulin‐like growth factor 1 (GH/IGF‐1) pathway, unique sequence change in the GH‐receptor (Seim et al., 2013), repression of telomerase activities (Gomes et al., 2011), and positive selection in telomere‐associated genes (Huang et al., 2019; Morgan et al., 2013).
