- Flow cytometric analysis of POLR1B in Hela cells (right histogram) compared to a negative control cell (left histogram). Samples were incubated with a POLR1B Antibody (N-term) (Product # PA5-48383) followed by incubation with a FITC-conjugated goat-anti-rabbit secondary antibody.

- Figure 6 DDX21-PLOR1B signaling axis regulated by lncRNA ZFAS1 in CRC cells and tissues. ( A and B ) The mRNA expression of POLR1B after overexpression or silencing lncRNA ZFAS1 in SW620 and SW480 cells by RT-PCR ( A ) and qPCR assay ( B ). ( C and D ) The expression levels of POLR1B after interfering DDX21 expression in both SW620 and SW480 cells detected by western blot ( C ) and qPCR assay ( D ). ( E and F ) Rescue experiments determining the POLR1B mRNA and protein expression levels treated by silencing of lncRNA ZFAS1 and overexpression of DDX21 in SW620 and SW480 cells assayed by qPCR assay ( E ) and western blot assay ( F ). ( G ) Representative analysis results of POLR1B expression in paired CRC tissues and controls assayed by RT-PCR and qPCR method. 5 representative data was shown. ( H ) Representative IHC imagines and Violin charts displaying the POLR1B protein expression based on the CRC patient tissues and matched tumor-adjacent controls ( n = 157). The bar represents 100mum. ( I ) Linear regression analysis illustrating a positive correlation between the expression of POLR1B and LncRNA ZFAS1 or DDX21. ( J and K ) Stratified Kaplan-Meier plot illustrating the impact of POLR1B high/low expression on the DFS and OS upon those patients with DDX21 high expression ( J ) or with ZFAS1 high expression ( K ). Data were shown as mean +- s.d. Two-tailed Student's t -tests were used. * P
