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). This evidence concerns the gene TBPL1 and Huntington disease.
