$( A ) U2OS cells, either stably expressing K294A upon doxycycline induction or uninduced controls, were biochemically fractionated into nuclear and cytoplasmic compartments. Western blot analysis confirmed fractionation quality using Lamin A/C as a nuclear marker and GAPDH as a cytoplasmic marker. Myc blotting verified the expression of K294A upon doxycycline induction. ( B ) Quantitative real-time PCR analysis revealed a significant reduction in the cytoplasmic levels of RORA and KCTD16 transcripts in K294A expressing cells compared with controls, while BNIP3 levels remained unchanged. ( C ) Western blot analysis further confirmed decreased protein levels of RORA and KCTD16 in K294A-expressing cells. Myc blotting verified stable K294A expression. ( D ) Densitometric analysis of RORA and KCTD16 protein bands from panel C was performed using ImageJ software. β-Actin was used as a loading control for normalization. Statistical analysis was calculated by performing two-tailed Student’s t -test.

( L ) Relative 5′-end loss of RORA and KCTD16 was assessed using an in vitro Xrn1 susceptibility assay. In K294A-expressing cells, both transcripts exhibited a level of 5′-end loss comparable to STAT3 , a known cCE target, relative to control cells. Statistical analysis was performed using one sample Student’s t -test.
