Figure Lengend Snippet: ( a ) Nucleotide composition around the 5′ end of reads in arsenite-treated and unstressed cells upon XRN1 silencing. All reads were used, irrespective of adaptor ligation status. ( b, c ) Scatter plot of annotated 5′ ( a ) and 3ʹ ( b ) UTR length against transcript differential length in arsenite-treated and unstressed cells. The box plots on the right side summarize the y-axis variable for significant and nonsignificantly shortened transcripts. ( d, e ) Scatter plot of ribosome profiling footprint ( d ) and translational efficiency ( e ) levels against differential length in arsenite-treated and unstressed cells. Transcripts are stratified by significance of shortening. The Pearson’s correlation coefficient and the Mann–Whitney U test p-value are shown.

Article Title: Identification of transcriptome-wide cobalt chloride-induced hypoxia-responsive long noncoding RNAs regulated by cytoplasmic mRNA capping enzyme

doi: 10.1101/2024.11.21.624636

Figure Lengend Snippet: (A) Western blot analysis of U2OS cells expressing ± K294A showed Myc-tagged K294A expression. The quality of nuclear and cytoplasmic fractionation was validated by the detection of nuclear marker Lamin A/C and cytoplasmic marker GAPDH. (B) The steady-state expression of NEAT1-209, LUCAT1-211, and MSC-AS1-212 was significantly decreased in K294A-expressing cells. Statistical analysis was conducted using a two-tailed Student’s t-test. (C) The impact of siRNA-mediated Xrn1 knockdown in U2OS cells on the stability of the Xrn1 exoribonuclease was evaluated using Western blot analysis. Simultaneously, the Western blot for Myc verified the expression of the K294A variant. β-Actin served as the internal control. (D) The relative expression levels of Xrn1 protein, following transfection with Xrn1 siRNA, were quantified by normalization against β-Actin protein expression in ±K294A cells. (E) The steady-state levels of NEAT1-209, LUCAT1-211, and MSC-AS1-212 were significantly elevated following the transfection of siRNA Xrn1 into K294A U2OS cells. Statistical analysis was conducted using the two-way ANOVA. Values are expressed as mean ± standard deviation (SD) from three biological replicates. Statistical significance is denoted as follows: ns indicates non-significant; *P < 0.05; **P < 0.005; ***P < 0.0005; ****P < 0.0001, with n ≥ 3.

doi: 10.1038/s41467-024-46943-z

Figure Lengend Snippet: Fig. 4 | P-bodies are the site of fast RNA decay. ACT-MBS MEF cells were treated with siRNA against (a–c) XRN1, (d–f) DDX6, or (b–c, e–f) scrambled siRNA (NC) for 72 h. Cells were treated with Rapa and DRB, and fixed at different time points. smFISH-IF experiments were conducted with FISH probes against ACTB-MBS and mGAPDH, and antibodies against DCP1a. a Representative image at 2 h post induc- tion for XRN1 siRNA treated cells.
