Interestingly, the ubiquitination gene UBXN1 (UBX domain protein 1), an important negative regulator of the unfolded protein response [102], was significantly up-regulated in the profiled tumor (x(T) = 1.75), but massively down-regulated in both cell lines (x(Φ) = −41.96, x(Θ) = −106.57). Here, UBXN1 is linked to neoplasm.
