Expressions of SH3PXD2A-AS1 were validated in a small CRC cohort, revealing that SH3PXD2A-AS1 was upregulated in CRC tissues relative to adjacent NCTs, as shown in RT-PCR (p = 0.0006, Figure 1A) and gel electrophoresis results (Figure S1A). The gene discussed is SH3PXD2A; the disease is colorectal carcinoma.
