While SLC6A1-AS1 expression was increased in immature neurons and MSPNs in middle-age, high SLC6A1-AS1 expression predicts better survival from cancer (cholangiocarcinoma; Wang et al., 2018), suggesting a potential inhibitory effect of SLC6A1-AS1 on cellular proliferation. Here, SLC6A1 is linked to cholangiocarcinoma.
