    ( a ) Cell proliferation and ( b ) cell viability alterations of HT-29 and <t>SW480</t> colorectal cancer cell lines following different folic acid (FA) supplies. Sulforhodamine B (SRB) was used for cell proliferation detection (* p ≤ 0.05, *** p ≤ 0.001), while cell viability data were obtained by alamarBlue assay (** p ≤ 0.01). FA-depleted cells were kept in media containing 0 ng/mL FA, whereas treated cells were exposed to 100 and 10,000 ng/mL FA for 72 h. The percentages of cell proliferation and viability were given relative to samples kept in the normal growth media. FA: folic acid.

    Genomic stability detection of HT-29 and SW480 cells exposed to different folic acid (FA) concentrations (0, 100, 10,000 ng/mL). ( a ) Micronucleus (MN) scoring was performed on DAPI- and anti-γ-H2AX-stained slides. Left: We obtained the results by proportioning the cells with MN with all cells counted (** p ≤ 0.01, *** p ≤ 0.001). Right: Representative γ-H2AX-positive micronuclei are indicated with arrows. ( b ) DNA integrity was evaluated with comet assay, additionally. Left: Graphs show the changes in genomic stability in consideration of comet tail DNA percentage (* p ≤ 0.05). Right: Characteristic comets of both cell lines were captured following different treatments. FA: folic acid.

    DNA methylation analysis of HT-29 and SW480 cell lines exposed to different folic acid (FA) concentrations. The methylation levels of long interspersed nuclear element 1 (LINE-1) CpG positions (pos 1, pos 2, pos 3) were ( a ) summarized and also ( b ) visualized individually to detect global DNA methylation changes. With the use of Reduced Representation Bisulfite Sequencing (RRBS) method, a genome-wide methylome profile of 10,000 ng/mL FA-treated cells was established in the comparison of cells kept in FA-free (0 ng/mL FA) media. ( c ) Firstly, the number of genes with altered methylation in the investigated CpG sites was assessed. “Hyper” and “hypo” sections indicate the number of genes with methylated and unmethylated CpG sites, respectively. The intersection of these two categories refers to the genes that possess both methylated and unmethylated CpG dinucleotides. ( d ) Heatmap shows the top 10 significantly ( p ≤ 0.05) enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways with the number of differentially methylated genes. ( e ) Pie charts represent the localization of differentially methylated sites (DMS) in distinct chromatin states. FA: folic acid; pos: CpG position; hyper: hypermethylation; hypo: hypomethylation; DMSs: differentially methylated sites; heterochrom/lo: heterochromatin or low signal region; txn: transcription; CNV: copy number variation; KEGG: Kyoto Encyclopedia of Genes and Genomes.

The abscissa indicates the nine sample names, and the ordinate represents the methylation level (standardized beta value). (B) The PCA chart indicates the similarity between the samples by the method of decreasing dimensions. The three groups did not cluster together, indicating that the similarity of the samples within the same group was poor, and there were no significant differences between the three groups. | Delta Beta| ≥ 0.12 ( P < 0.01) is used to screen out the different sites, Delta Beta ≥ 0.12 indicates that the degree of methylation is increased, and Delta Beta ≤ –0.12 indicates that the degree of methylation is decreased. Three volcano plots between groups show the differential of the methylation sites.

    Figure Lengend Snippet: The culture and activation process of ovarian tissue in vitro did not cause abnormal DNA methylation. (A) No significant differences in total genome DNA methylation between three groups of human ovarian tissues were observed: normal group A (A1, A2, A3) (normal human ovarian fragment), control group B (B1, B2, B3) (treated with culture media only), and activated group C (C1, C2, C3) (treated with 10 μM activator MHY1485). The abscissa indicates the nine sample names, and the ordinate represents the methylation level (standardized beta value). (B) The PCA chart indicates the similarity between the samples by the method of decreasing dimensions. The three groups did not cluster together, indicating that the similarity of the samples within the same group was poor, and there were no significant differences between the three groups. | Delta Beta| ≥ 0.12 ( P < 0.01) is used to screen out the different sites, Delta Beta ≥ 0.12 indicates that the degree of methylation is increased, and Delta Beta ≤ –0.12 indicates that the degree of methylation is decreased. Three volcano plots between groups show the differential of the methylation sites.

    Article Snippet: We further used a human high-throughput DNA methylation microarray (Infinium Human Methylation EPIC BeadChip: 850k chip) to analyze the effects of the activator MHY1485 on the methylation status of the human genome in the ovary.
