Figure Legend Snippet: MiR‐99a‐5p, miR‐100‐5p, and miR‐125b‐5p expression and correlations of primary microRNA (pri‐miRNA), long interspersed noncoding RNA (lincRNA), and protein‐coding gene expression from chromosomes 11 and 21 in malignant germ cell tumor (GCT) clinical samples and cell lines relative to nonmalignant (gonadal and teratoma) control samples. (A) Normalized log 2 microarray expression levels for miR‐99a‐5p, miR‐100‐5p, and miR‐125b‐5p. (B) Summated normalized log 2 microarray intensity ratio boxplots showing seed intensity for the nucleotide (nt) sequences ‘ACCCGU’ (left; 2‐7nt seed of miR‐99a‐5p/miR‐100‐5p) and ‘CCCUGA’ (right; 2–7 nt seed of miR‐125b‐5p). The clinical samples in (A) and (B) represent normal gonads ( n = 8, green), teratomas (Ter; n = 5, brown), seminoma (Sem; n = 13, blue), yolk sac tumor (YST; n = 12, yellow), embryonal carcinoma (EC; n = 3, red), and malignant GCT cell lines (CL; n = 6, gray). In all panels in (A) and (B), the horizontal bar = median expression and the box = minimum to maximum values with whiskers = standard deviation. It should be noted that it is not possible to reliably apply statistical testing to these normalized log 2 microarray expression levels in (A) nor the derived intensity ratios in (B). (C) Correlations between expression of pri‐miRNAs from chromosome 11 (chr11; left panel; pri‐miR‐125b‐1 vs . pri‐miR‐100) and chromosome 21 (chr21; right panel; pri‐miR‐125b‐2 vs . pri‐miR‐99a). (D) Correlation between pri‐miRNA expression from chr11 and chr21. (E) Correlation between expression of associated lincRNA/protein‐coding genes on chr11 ( MIR100HG/BLID ) and chr21 ( MIR99AHG ), which include the regions encoding the miRNAs of interest. In (D, E), the comparison for each gene type is indicated by a symbol (circle, triangle, square, diamond), as described in the Figure. All expression values are referenced to the mean of pooled normal gonadal (ovary/testis) control samples. Color‐coding for (D) and (E) is as described in the color key (C). For experiments (C–E), statistical significance is determined using linear regression analysis.

Figure Legend Snippet: DNA methylation at chromosome 11 and 21 loci in malignant germ cell tumor (GCT) cells. In each panel in (A, B), the upper figure shows the cumulative levels of endogenous CpG DNA methylation across the chromosome 11 (chr11; A) or chromosome 21 (chr21; B) locus, while the lower figure represents the genomic location map of all the CpG sites examined. The colors in each bar (from the base to top) correspond to the individual CpG coordinates (from left to right) in the respective genomic map. The size of each bar represents the average percentage of methylation per CpG site, ranging from 0 (no methylation) to 100% (fully methylated). Accordingly, given 23 and 12 CpG sites assessed for chr11 and chr21, respectively, the maximum cumulative methylation score for each is 2300 and 1200. P ‐values (Student's t ‐test): **** P < 0.0001. The controls comprised five tissues/cell lines, namely three normal cervical squamous epithelium samples and the normal cell lines HFFF2 (fibroblasts) and 340‐RPE‐11tv (retina). (C) Overall DNA methylation percentage (%) for the malignant GCT cell lines, testis, and controls. The percentage given represents methylation across 35 CpG sites on both chr11 and chr21 and thus is out of a total cumulative methylation score of 3500.

All total concentrations used were 16.7 n m ; where combination microRNA (miRNA) mimics were used, this was an 8.33 n m equimolar concentration of each. (C) Sylamer plots showing the single summed significance score (SSSS) of the seed complementary regions (SCRs) corresponding to miR‐99a‐5p/miR‐100‐5p (blue line) and miR‐125b‐5p (green line) in the ranked gene lists from TCam2 (left) and 1411H (right) cells at d2 following treatment with 16.7 n m combination miR‐100‐5p and miR‐125b‐5p mimic replenishment, compared with 16.7 n m MNC‐treated cells. Log 10 ‐transformed P ‐values for each SCR word are on the y ‐axis, against the ranked gene list (from downregulated on the left to upregulated on the right) on the x ‐axis. A positive y ‐axis deflection on the left‐hand side of the plot signifies SCR enrichment in downregulated genes. Error bars = standard error of the mean (SEM). Statistical significance (Student's t ‐test): * P ≤ 0.05, ** P < 0.01, *** P < 0.005, **** P < 0.001; NS, nonsignificant.

Figure Legend Snippet: Combination miR‐100‐5p/miR‐125b‐5p replenishment results in LIN28A depletion and late concomitant increases in let‐7 tumor suppressor microRNA (miRNA) levels in malignant germ cell tumor (GCT) cells. (A) LIN28A quantitative RT‐PCR (qRT‐PCR) levels in TCam2 (left) and 1411H (right) cells at day (d) 1, d2, and d3 following microRNA (miRNA) replenishment. For this work, cells were treated as described in Fig. , namely total miRNA/mimic‐negative‐control (MNC) concentrations were used at 16.7 n m ; and for combination miRNA mimics, this was an 8.33 n m equimolar concentration of each, as per the color‐code below the qRT‐PCR plots. (B) Representative LIN28A protein levels by western blot on d2 and d3 in TCam2 cells. (C) Let‐7b‐5p miRNA expression levels as quantified by qRT‐PCR at d1, d2, d3, and d6, and (D) representative LIN28A protein levels by western blot at d4 and d7; both following mimic replenishment in TCam2 cells as detailed in (A) above. Note that the experiments in (A) and (C) were performed in biological triplicate (i.e., n = 3) for individual treatment conditions, each with technical replicates; the data shown in (A) and (C) represent the mean and error bars = SEM of these biological triplicate values. For (A) and (C), statistical significance using Student's t ‐test is shown with the appropriate comparisons: * P ≤ 0.05, ** P < 0.01, *** P < 0.005, **** P < 0.001. Only significant comparisons are shown. For representative western blots shown in (B) and (D), these were from experiments performed in biological triplicate (i.e., n = 3), with tubulin protein used as a loading control. The experimental condition used is shown above each blot. The quantification number under each band on the blot represents densitometry analysis of protein expression normalized to tubulin using imagej software and referenced to expression in mimic‐negative‐control (MNC)‐treated cells, which are given an arbitrary value of 1.00. The size of the specific protein is listed in kilodaltons (kDa) on the right‐hand side of the blots. (E) Co‐expression analysis of let‐7b‐5p levels ( x ‐axis) with LIN28A mRNA levels ( y ‐axis) in malignant GCT tissue samples ( n = 156). Data obtained from the independent ENCORI Pan‐Cancer Analysis Platform. For the co‐expression analysis in (E), statistical significance is determined using linear regression analysis; the red line indicates the best fit line based on this analysis. (F) Graphical abstract summarizing potential miRNA effects on the cell cycle in malignant GCTs derived from data from this manuscript and published studies. Reduced levels (blue arrows) of tumor suppressor miR‐100‐5p/miR‐125b‐5p miRNAs result in increased levels (red arrows) of, for example, TRIM71 , with concomitant reductions in cyclin‐dependent kinase (CDK)‐interacting protein/kinase inhibitory protein (CIP/KIP) family members such as CDKN1A (blue arrow) , coding for p21 protein. In turn, this allows cell cycle progression through reduced physical inhibition (i.e., increased activity; black arrows) of CDK2 and CDK4 . As demonstrated in this study, replenishment of these downregulated miRNAs, or TRIM71 kd, reduces cell cycle proliferation through converse effects on the pathway and thus G0/G1 and G1/S transition. Further contributions to malignant GCT pathogenesis are likely from, for example, reduced miRNA‐mediated control of LIN28A levels. High LIN28A levels cause increased degradation of let‐7 tumor suppressor miRNA family members, reducing its own inhibition via the LIN28A / let‐7 feedback loop, resulting in cellular proliferation . To add to the complexity, TRIM71 itself is also a direct mRNA target of the let‐7 family . Finally, the effects of overexpressed oncogenic miR‐371~373 and miR‐302/367 miRNAs also converge on the cell cycle through CIP/KIP family members . 3′UTR, 3′ untranslated region.
