Article Title: Dormant Metastases Exhibit a Unique Phenotype Primarily Promoted by the Ch25h Gene and Are Maintained in Dormancy by T Lymphocytes

doi: 10.1002/mco2.70437

Figure Lengend Snippet: Genes differentially expressed in the dormant metastasis group. Heat maps are presented to illustrate the differential expression data between the three metastatic groups obtained from RNA‐Seq (A), or RT‐qPCR in genes involved in the cholesterol synthesis pathway (B), in chemokine genes (C), and in surface marker genes (D). Only genes that displayed a greater than twofold difference in expression (log2>1) with a p ‐value less than 0.001 were identified and plotted in the heatmap. The expression values are presented as log2 values and are scaled by gene. In RT‐qPCR assays, the expression levels of the genes of interest were determined with respect to the levels of the β‐actin and GAPDH housekeeping genes. The data for the overt‐met group were set to 1. The values represent the means of three independent experiments performed in duplicate. The statistical analysis was performed using ANOVA, followed by Tukey's post hoc test.

Figure Lengend Snippet: MicroRNAs that are differentially expressed in the dormant metastasis group. (A) Heat map is presented to illustrate the differential expression data between the three metastatic groups. (B) miRNA enrichment analysis of miRNAs differentially expressed in dormant‐met group (miEAA). The expression of 834 miRNAs was measured using the ‘mouse miRNome qPCR arrays 18.0’ (Genecopoeia). Only miRNAs that displayed a greater than twofold difference ( p < 0.01) when comparing the dormant‐met group with the nude‐met and overt‐met groups were plotted. The expression levels of the miRNAs of interest were determined with respect to the levels of six housekeeping snRNAs (MK1‐MK6). The data for the overt‐met group were set to 1. The values are presented as the means of three independent experiments, each performed in duplicate. The statistical analysis was conducted using an ANOVA test, followed by a Tukey's post hoc test.

doi: 10.1016/j.apsb.2024.07.018

Figure Lengend Snippet: AVN A suppresses the miR-17-92 cluster to derepress Bim level. (A, B) HCT116 (A) and HCT-8 (B) cells were treated with 5-FU, AVN A, or combination for 24 h. Western blot was utilized for the levels of Bim, Mcl-1, Bcl-xL, Bcl-2, PUMA, and Bik. (C) CRC cells were exposed to 5-FU treatment alone and the combination and cultured with 1 μg/mL of actinomycin D for the indicated time. The mRNA stability of Bim was assessed using qPCR assay. (D) HCT-8 cells were treated with 5-FU and AVN A alone or together for 24 h and applied to qPCR analysis by miRNA array. Volcano plot demonstrates differentially expressed miRNAs via the combination of P values (cutoff = 0.05) and relative fold change (cutoff = 1.5). The downregulated miRNAs are shown in blue circles, whereas upregulated miRNAs are represented in red circles. (E) Following treatment with AVN A for 24 h, miR-17-92 cluster levels in CRC cells were analyzed by qPCR. (F) Heatmap of miR-17-92 cluster in the TCGA CRC database. (G) The differentially expressed miRNAs in 537 CRC samples and 9 adjacent normal tissues derived from TCGA are visualized in a volcano plot.

doi: 10.1038/srep15812

Figure Lengend Snippet: A miR array revealed that the expression levels of 12 miRs, out of the 84 miRs examined, were up-regulated more than 5-fold in the glutamate-treated explants over the α-MSH + glutamate-treated counterparts at 48 h post stimulation, n = 5/group ( A ). The relative expression levels of miR-194, the miR exhibiting the most dramatic change in the miR array, were confirmed in a separate experiment by qPCR, n = 5–10/group ( B ). ** p < 0.01.
