Ustered adherent growth. Compared using the handle group, HepG2 cells progressively lost their original normalcell morphology with escalating SBP-2A concentrations, which showed that the number of cells decreased substantially, the cells became flat and contracted into a lump, and also the cell membranes were broken, which resulted in unclear boundaries in between the cells and cell fragments. These final results showed that SBP-2A substantially inhibited the proliferation of HepG2 cells in vitro.Frontiers in Pharmacology | frontiersin.orgApril 2022 | Volume 13 | ArticleSu et al.Structural Characterization and Hepatoma ActivityFIGURE 7 | Edu staining (A), and Edu-positive (+) cells were counted by ImageJ software (B). Compared to the non-SBP-2A-treated group, p 0.0001. The number of apoptotic cells was determined by Annexin V-FITC/PI double staining (C), and also the DNA contents within the cell cycle was measured quantitatively by flow cytometry (D).TABLE 4 | Effect of SBP-2A on the cell cycle distribution of HepG2 cells for 48 h (n = 3).

The nuclei of the proliferating cells have been stained red by EdU and stained blue by DAPI (Figure 7A). Compared with the negative control group, the percentage of EdU-positive cells decreased considerably with growing drug concentration (p 0.05) (Figure 7B). ThisDNA Content Quantitation Assay As displayed in Figure 7C, by analysing the percentage of DNA content material in G0/G1, S and G2/M cells in the cell cycle, we found that compared together with the untreated group, SBP-2A improved the percentage of cells inside the G1 phase from 53.IFN-alpha 1/IFNA1 Protein Formulation 34 0.PMID:23983589 06 to 62.51 0.54 (p 0.0001), plus the percentage of cells within the S phase was decreased from 20 1.1 to 12.34 1.66 (p 0.01), indicating a dose-dependent effect; the effect in cells inside the G2/M phase was statistically insignificant (Figure 7D and Table four). This observation was accompanied by a rise within the quantity of cells in the G0/G1 phase. HepG2 cells were blocked by SBP-2A inside the G0/G1 phase with the cell cycle.Frontiers in Pharmacology | frontiersin.orgApril 2022 | Volume 13 | ArticleSu et al.Structural Characterization and Hepatoma ActivityFIGURE 8 | The impact of SBP-2A on the mRNA expression of P53 and CyclinD1 was determined by qRT CR (A,B).
