First, we assessed DARPP-32 and t-DARPP transcript levels in a RNA-Seq dataset consisting of 29 human SCLC patients, 23 of which also contained corresponding matched normal lung tissue.37 We found that t-DARPP transcripts were elevated in SCLC relative to normal lung tissue (Fig. 5a). The gene discussed is PPP1R1B; the disease is small cell lung carcinoma.
