SLC6A14 is proposed to be upregulated in several cancers with the purpose of delivering amino acid nutrients into the cells, including colorectal cancer (Gupta et al., 2005), cervical cancer (Gupta et al., 2006), estrogen receptor positive breast cancer (Karunakaran et al., 2011; Schaller and Lauschke, 2019), and pancreatic cancer (Penheiter et al., 2015; Coothankandaswamy et al., 2016). This evidence concerns the gene SLC6A14 and cancer.
