Figure Lengend Snippet: Fig. 7. Time dependent HindIII digest of pUC19 monitored by CGE. All samples were kept for 18 min at 37 °C. The enzyme was added after varying timesteps to the samples, resulting in different enzyme treatment times as indicate on the x axis. Two CGE runs were performed on the same samples. The first run was directly performed after the incubation with HindIII (red), the second run (blue) 25 min later after the start of the first measurement . HindIII was not deactivated, thus additional action of the enzyme was observed between the two runs, as appearent in the higher amount of plasmid in the linear conformation in the blue curve and the difference between the Blind (no enzyme) and sample at t = 0 min, where the enzyme was added at the end of the incubation period.

Article Snippet: Linear plasmids was produced by digest with HindIII (Jena Bioscience), while open-circular plasmids was produced Nt.BspQI (NEB).

Article Title: Genome-Wide Profiling of Cervical RNA-Binding Proteins Identifies Human Papillomavirus Regulation of RNASEH2A Expression by Viral E7 and E2F1

doi: 10.1128/mBio.02687-18

Figure Lengend Snippet: RNASEH2A is regulated by viral E7 via E2F1 and its expression in association with E2F1 and PCNA in cervical and endocervical cancer and head and neck squamous cell carcinoma. (A) Read coverage maps showing the RNA expression levels of all 7 cervical cancer samples and 7 normal samples for RNASEH2A. Distributions of RNASEH2A reads (blue for normal, red for cancer) along with RNASEH2A transcript structure were visualized using the Integrative Genomics Viewer (IGV). (B) Correlation between RNASEH2A and HPV16 E7 mRNAs in 48 clinical cervical lesion samples, including 25 CIN2-CIN3 and 23 cervical cancer tissue samples. (C) siRNA-specific knockdown of HPV16 or HPV18 E7 expression in CaSki (HPV16 + ) cells or HPV18-immortalized human foreskin keratinocytes (HFK18) with respect to expression of RNASEH2A, PCNA, and NOVA1 was evaluated by Western blotting. si-NS, nonspecific siRNA; si-E7, HPV16 or HPV18 E7-specific siRNA. Knockdown efficiency of E7 expression was evaluated by analysis of increased expression of p53 due to the E7 siRNA also targeting the overlapped bicistronic E6 RNA ; tubulin served as a sample loading control. (D) siRNA-specific knockdown of HPV16 or HPV18 E6 or E7 in CaSki (HPV16 + ) or HeLa (HPV18 + ) cells with respect to RNASEH2A expression was evaluated by TaqMan RT-qPCR. si-NS, nonspecific siRNA; si-E6, HPV16 or HPV18 E6-specific siRNA; si-E7, HPV16 or HPV18 E7-specific siRNA. (E and F) Specific-siRNA knockdown (E) or ectopic expression of E2F1 (F) in CaSki or HeLa cells with respect to RNASEH2A expression was evaluated by TaqMan RT-qPCR. si-NS, nonspecific siRNA; si-E2F1, E2F1-specific siRNA; p, control vector; p-E2F1, E2F1-expression vector. * , P < 0.05; * * , P < 0.01; ** * , P < 0.001. The relative expression levels of RNASEH2A in panels D, E, and F are shown as means ± SD for each treatment group determined in duplicate from three independent experiments, with the level in the si-NS (D and E) or vector control (F) group being set to 1. (G) Increased coexpression of RNASEH2A, PCNA, and E2F1 in cervical squamous cell carcinoma, endocervical adenocarcinoma (CESC), and head and neck squamous cell carcinoma (HNSC). Data were extracted from the TCGA data sets using TCGA2STAT R package version 1.2 ( https://CRAN.R-project.org/package=TCGA2STAT ).

Article Snippet: CaSki and HeLa cells were also transfected with 2 μg of an E2F1 expression vector (pRcCMV-HA-E2F1; Addgene, Watertown, MA) with X-tremeGENE HP DNA transfection reagent (Roche), and total RNA from the cells with E2F1 overexpression was analyzed for RNASEH2A expression by real-time RT-qPCR.
