Cell cycle distribution of U2OS and N6AMT1-depleted cells.
(A) Schematic representation of Cyclin A, B and E expression levels during the cell cycle. Serum depletion and thymidine and nocodazole treatment were used to arrest the cells at the indicated cell cycle points. (B-E) Cell cycle phase distribution of the U2OS and N6AMT1-knockout cell lines after the indicated treatments was determined by propidium iodide staining and flow cytometry analysis. The average of three biologically independent samples is shown. Statistical analysis was performed with GraphPad Prism 8.4.3. The data are presented as the means ± SDs; *P < 0,05, **P < 0,001, ***P < 0,0001 according to multiple t tests.</p
N6AMT1 impacts the cyclin E levels.
(A) Unsynchronized cells and cells that were synchronized with serum depletion, thymidine treatment and nocodazole treatment were analysed via Western blotting with antibodies against Cyclin A, Cyclin B1, Cyclin E, N6AMT1, TRMT112 and GAPDH. 10 μg of total protein was loaded per well. (B-E) Cyclin A, cyclin B, cyclin E and TRMT112 levels in U2OS and ΔN6AMT1#1 cells. Western blotting images were quantified using ImageJ, and the average of three biologically independent samples is shown. Statistical analysis was performed with GraphPad Prism 8.4.3. The data are presented as the means ± SDs; *P < 0,05, **P < 0,001, ***P < 0,0001 according to multiple t tests. (F) Untreated cells and cells that were treated with the indicated siRNAs were analysed via Western blotting with antibodies against Cyclin E, N6AMT1 and GAPDH. (G) Cyclin E levels in U2OS cells after siRNA treatment. Western blotting images were quantified using ImageJ, and the average of three biologically independent samples is shown. Statistical analysis was performed with GraphPad Prism 8.4.3. The data are presented as the means ± SDs; *P < 0,05, **P < 0,001, ***P < 0,0001 according to multiple t tests. (H) qRT‒PCR verification of cyclin A, cyclin B and cyclin E levels in ΔN6AMT1#1 cells. The average of three biologically independent samples is shown. Statistical analysis was performed with GraphPad Prism 8.4.3. The data are presented as the means ± SDs; *P < 0,05, **P < 0,001, ***P < 0,0001 according to multiple t tests.</p
Changes in cyclin levels after thymidine block.
(A) Schematic representation of the experimental setup for cell synchronization early in the S phase. The cyclin A, B1 and E levels in (B) U2OS and (C) ΔN6AMT1#1 were analysed via Western blotting at the indicated timepoints. Cyclin A, B and E images were obtained after exposure time of 2 min for U2OS and 15 min ΔN6AMT1#1 samples. (D-F) Graphical representation of changes in the cyclin levels. Western blotting images were quantified using ImageJ, and the average of three biologically independent samples is shown.</p
