The set of HD-associated genes oscillating in SW620 cells included genes involved in cell death (CASP3, TP53, CYSC), mitochondrial oxidative phosphorylation (SOD2, SDHD, NDUFA2, NDUFA4, NDUFA4L2, NDUFAB1, NDUFS3, UQCR10, and UQCRHL), and gene transcription by RNA polymerase II (POLR2A, POLR2C, POLR2K, TAFA4, TBP, and TBPL1). Here, NDUFA2 is linked to Huntington disease.
