DHRS4 and cancer: For example, Li et al. revealed that a lncRNA named AS1DHRS4 (antisense 1 dehydrogenase/reductase SDR family member 4), transcribed from the locus of the DHRS4 gene known to be involved in cancer, modulated the expression of DHRS4 by epigenetic regulation at the DHRS4L2 promoter region [44].
