Abstract
Teratocarcinoma is one type of testis cancer that can be represented in the youth population and usually shows itself with swelling of the testis and edema and a rise of BHCG and alpha-fetoprotein, but spontaneous rupture is a rare manifestation. A 23-year-old man was referred to the Sina Hospital with complaints of testis pain and swelling. Laboratory findings were alpha f.p more than 2,000, BHCG titer 255.21, and LDH 504. Sonography findings showed the right testis had been detected with a heterogeneous mass with vascularity and cystic area with microcalcification, measuring 76*69 mm. During surgery, we faced rupture tumor that was unusual and rare. The radical orchidectomy was done successfully without any complications. After the surgery, pathology showed teratocarcinoma of the right testis, and a 6-month observation and follow-up were done without any complication.

Abstract
Germ cell tumors (GCTs) are rare tumors that can develop in both sexes, peaking in adolescents. To understand the mechanisms that underlie germ cell transformation, we established a GCT mouse model carrying germ cell-specific BRafV600E mutation with or without heterozygous Pten deletion. Both male and female mice developed monolateral teratocarcinomas containing embryonal carcinoma (EC) cells that showed an aggressive phenotype and metastatic ability. Germ cell transformation started in fetal gonads and progressed after birth leading to gonadal invasion. Early postnatal testes showed foci of tumor transformation, while ovaries showed increased number of follicles, multi-ovular follicles (MOFs) and scattered metaphase I oocytes containing follicles. Our results indicate that Mapk over-activation in fetal germ cells of both sexes can expand their proliferative window leading to neoplastic transformation and metastatic behavior.

Abstract
Background Ovarian cancer causes more deaths than any other cancer of the female reproductive system because there is no effective screening and most women are diagnosed at advanced stages. The probability of survival at 5 years is less than 30%, and the limitation is that it will not respond to chemotherapy protocol and surgery as well. Moreover, some evidence have shown potential anticancer properties of flavonoids, protective chemicals in plant foods, such as being an antioxidant, antiestrogenic, antiproliferative, and antiinflammatory. In this study, the anticancer activity of crude ethanol extracts of leaves from Adhatoda vasica was investigated. Results By the application of a cell-based assay, the LC 50 value of the A. vasica which showed anticancer effect was used for further studies. The cell line treated with LD 50 value of A. vasica extracts was observed for 0 h, 24 h, and 48 h to reveal the inhibition of the metastatic property in treated PA1 cells. The mRNA isolated from the teratocarcinoma PA1 cells treated with the A. vasica extract was further converted to cDNA and was amplified for the analysis of the p53 gene, p21 gene, and GAPDH gene expression. The expression in treated cells and the untreated control indicated the activity of the A. vasica extract against the ovarian cancer. Conclusion The present study suggested the antiproliferative and antimetastatic effects of medicinal plant A. vasica on PA1 cells.

Abstract
As the most toxic dioxin, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) has gained lots of concerns, due to its diverse deleterious effects. However, the knowledge on carcinogenic risk of TCDD during early stage of development remains scarce. The in vivo teratoma formation model based on the transplantation of embryonic stem cells (ESCs) in immunodeficient mice is appealing for studying pluripotency and tumorigenicity in developmental biology, and also shows promise in environmental toxicology, especially in carcinogenesis researches. In this study, the malignant transformation of mouse embryonic stem cells (mESCs) pretreated with TCDD was investigated during their in vivo differentiation using teratoma formation model. Based on characterization of the pluripotency and differentiation capabilities of mESCs, evil changes in teratomas derived from TCDD-exposed mESCs were systematically studied. The results showed that TCDD significantly up-regulated CYP1A1 transcriptional levels in mESCs, elevated the incidence of malignant change in mESC-derived teratomas, and caused indefinite proliferation capabilities in sequential cultures of tumor tissues. The findings suggested that TCDD could exert carcinogenic effect on mESCs during their differentiation into teratoma in vivo, and more attention should be paid to the adverse health effects of this chemical during gestation or early developmental period.

Abstract
The paternally-imprinted genes insulin-like growth factor 2 (IGF2), H19, delta-like homologue 1 (DLK1), and maternally-expressed gene 3 (MEG3) are expressed from the tandem gene loci IGF2-H19 and DLK1-MEG3, which play crucial roles in initiating embryogenesis and development. The erasure of imprinting (EOI) at differentially methylated regions (DMRs) which regulate the expression of these genes maintains the developmental quiescence of primordial germ cells (PGCs) migrating through the embryo proper during embryogenesis and prevents them from forming teratomas. To address the potential involvement of the IGF2-H19 and DLK1-MEG3 loci in the pathogenesis of embryonal carcinoma (EC), we investigated their genomic imprinting at DMRs in the human PGC-derived EC cell line NTera-2 (NT2). We observed EOI at the IGF2-H19 locus and, somewhat to our surprise, a loss of imprinting (LOI) at the DLK1-MEG3 locus. As a result, NT2 cells express imprinted gene ratios from these loci such that there are i) low levels of the proliferation-promoting IGF2 relative to ii) high levels of the proliferation-inhibiting long noncoding RNA (lncRNA) H19 and iii) high levels of proliferation-promoting DLK1 relative to iv) low levels of the proliferation-inhibiting lncRNA MEG3. Consistent with this pattern of expression, the knockdown of DLK1 mRNA by shRNA resulted in decreased in vitro cell proliferation and in vivo tumor growth as well as decreased in vivo organ seeding by NT2 cells. Furthermore, treatment of NT2 cells with the DNA methyltransferase inhibitor 5-aza-2'-deoxycytidine (5-azaD) inhibited their proliferation. This inhibition was accompanied by changes in expression of both tandem gene sets: a decrease in the expression of DLK1 and upregulation of the proliferation-inhibiting lncRNA MEG3, and at the same time upregulation of IGF2 and downregulation of the lncRNA H19. These results suggest that the DLK1-MEG3 locus, and not the IGF2-H19 locus, drives the tumorigenicity of NT2 cells. Based on these results, we identified DLK1 as a novel treatment target for EC that could be downregulated by 5-azaD.

Abstract
LSD1/KDM1 is a histone demethylase that preferentially removes methyl groups from the mono- and di-methylated lysine 4 in histone H3 (H3K4), key marks for active chromatin for transcriptional activation. LSD1 is essential for pluripotent embryonic stem cells and embryonic teratocarcinoma/carcinoma cells and its expression is often elevated in various cancers. We developed a new LSD1 inhibitor, CBB3001, which potently inhibited LSD1 activity both in vitro and in vivo. CBB3001 also selectively inhibited the growth of human ovarian teratocarcinoma PA-1 and mouse embryonic carcinoma F9 cells, caused the downregulation of pluripotent stem cell proteins SOX2 and OCT4. However, CBB3001 does not have significant inhibition on the growth of human colorectal carcinoma HCT116 cells or mouse fibroblast NIH3T3 cells that do not express these stem cell proteins. Our studies strongly indicate that CBB3001 is a specific LSD1 inhibitor that selectively inhibits teratocarcinoma and embryonic carcinoma cells that express SOX2 and OCT4.

Abstract
Protein modification by O-linked N-acetylglucosamine (O-GlcNAcylation) is one of the post transcriptional modifications occurring on cellular proteins. This paper provides a data set relating to the O-GlcNAcylation of cellular proteins detected by RL2 and CTD110.6 antibodies, which are commonly used for detection of protein O-GlcNAcylation, in 2-deoxy-d-glucose (2DG)-treated human teratocarcinoma NCCIT cells in support of the research article entitled “A novel, promoter-based, target-specific assay identifies 2-deoxy-d-glucose as an inhibitor of globotriaosylceramide biosynthesis” (Okuda et al., 2009) [1]. The main article described a suppressive effect of 2DG on an Sp1 target gene in NCCIT cells and discussed the relationship between the effect of 2DG and O-GlcNAcylation status of Sp1. The data in this paper complements this relationship by Western blotting and clearly showed that the 2DG treatment increased O-GlcNAcylation of cellular proteins in NCCIT cells, whereas the RL2 and CTD110.6 epitopes were detected in a different manner. The RL2 epitope was detected on Sp1 during 2DG treatment, and the level was transiently increased at 24 h. In contrast, the CTD110.6 epitope became detectable on Sp1 over 72 h after 2DG treatment, and then the other proteins containing CTD110.6 epitopes also appeared in the cell lysates and the anti-Sp1 antibody precipitates.

Abstract
Embryonal carcinoma cells, stem cells of teratocarcinomas, are pluripotent stem cells and also prototypes of embryonic stem cells. Embryonal carcinoma cells contain large amounts of a highly branched poly-N-acetyllactosamine called embryoglycan, which has a molecular weight of approximately 10,000 or greater, and is asparagine-linked. This glycan was found by analyses of fucose-labeled glycopeptides, and its characteristics were established by biochemical analyses. The content of embryoglycan progressively decreases during the in vitro differentiation of embryonal carcinoma cells. Embryoglycan is also abundant in mouse embryonic stem cells and preimplantation mouse embryos, and decreases during embryogenesis. Embryoglycan carries a number of carbohydrate markers of murine pluripotent stem cells. Lewis x markers, such as SSEA-1, 4C9 antigen, and binding sites for Lotus tetragonolobus agglutinin are of particular importance. 4C9 antigenicity requires clustering of Lewis x, best accomplished by poly-N-acetyllactosamine branching, whereas SSEA-1 does not. Although in vivo evidence is lacking, these epitopes have been suggested to participate in cell-to-cell and cell-to-substratum adhesion. Other markers on embryoglycan include α-galactosyl antigens such as ECMA-2, and binding sites for Dolichos biflorus agglutinin, the epitope of which is considered to be identical to Sda antigen, namely, GalNAcβ1-4(NeuAcα2-3)Galβ1-4GlcNAc. While embryoglycan is also present in human teratocarcinoma cells, the carbohydrate markers characterized in human pluripotent stem cells to date are largely carried by glycolipids and keratan sulfate. Information on embryoglycan and markers carried by it may assist in the development of new markers of human pluripotent stem cells and their progenies.

Abstract
Background Deficiency in Vitamin D3 (cholecalciferol) may predispose to some malignancies, including gonadal tumors and in experimental models vitamin D3 has been proven to inhibit the growth of cancer cells. To learn more about the potential role of vitamin D3 in cancerogenesis, we evaluated the expression and functionality of the vitamin D receptor (VDR) and its role in metastasis of ovarian cancer cells and of murine and human teratocarcinoma cell lines. Methods In our studies we employed murine embrynic stem cells (ESD3), murine (P19) and human (NTERA-2) teratocarcimona cells lines, human ovarian cancer cells (A2780) as well as purified murine and human purified very small embryonic like stem cells (VSELs). We evaluated expression of Vitamin D3 receptor (VDR) in these cells as well as effect of vitamin D3 exposure on cell proliferation and migration. Results We here provide also more evidence for the role of vitamin D3 in germline-derived malignancies, and this evidence supports the proposal that vitamin D3 treatment inhibits growth and metastatic potential of several germline-derived malignancies. We also found that the ESD3 murine immortalized embryonic stem cell line and normal, pluripotent, germline-marker-positive very small embryonic-like stem cells (VSELs) isolated from adult tissues are stimulated by vitamin D3, which suggests that vitamin D3 affects the earliest stages of embryogenesis. Conclusions We found that however all normal and malignant germ-line derived cells express functional VDR, Vitamin D3 differently affects their proliferation and migration. We postulate that while Vitamin D3 as anticancer drug inhibits proliferation of malignant cells, it may protect normal stem cells that play an important role in development and tissue/organ regeneration.

Abstract
François Jacob tackled embryonic development from 1972 onwards, in the "Génétique cellulaire" Unit of the Molecular Biology Department at the Pasteur Institute, taking as models teratocarcinoma and the early stages of mouse embryo development. Studies on teratocarcinoma provided no major information about developmental processes, but they were the essential step without which embryonic stem cells (ES, iPS) would probably not have been discovered. The mechanisms of development were revealed by genetic approaches coupled to molecular biology, but with the Drosophila model rather than the mouse embryo. Since these studies, it has been revealed that developmental mechanisms among animals have proven to be universal. None of these results were predicted in 1972.

Abstract
Cancer stem cells (CSCs) are considered as the initiators of the carcinogenic process and are therefore emerging targets for innovative anticancer therapies. In order to evaluate the anticancer chemopreventive activity of flavagline derivatives, we used the pluripotent teratocarcinomal cell as a model of Oct4-expressing cancer stem-like cell and determined the underlying cellular and molecular mechanisms induced by a synthetic flavagline. We precisely investigated the effects of the flavagline derivative FL3 on the human embryonal carcinoma (EC) cell line NT2/D1 and compared the responses to those of a normal more restrictive pluripotent stem cell line (i.e. BJ fibroblast cell line). FL3 selectively inhibited the proliferation of NT2/D1 cells by inducing G1 phase cell cycle arrest in a dose-dependent manner. Moreover, FL3 treatment specifically triggered apoptosis in association with an induction of the phosphorylation of p38 mitogen-activated protein kinase (MAPK) and caspase-3 activation followed by a drastic downregulation of the master regulator of stemness Oct4. Forced inhibition of p38 MAPK activity by the specific pharmacological inhibitor SB203580 or by p38 MAPK gene knockdown using small-interfering RNA (siRNA) counteracted the effects of FL3, demonstrating that its chemopreventive action is related to growth inhibition and a p38-dependent caspase-3-dependent induction of apoptosis in Oct4-expressing CSCs. This study also shows that FL3 selectively kills poorly differentiated and highly aggressive carcinomal cells, but has little effect on normal stem-like cells. Thus FL3 offers great promise for cancer treatment since it is able to target the carcinogenic process without affecting normal cells.

Abstract
Mixed Germ Cell Tumours (MGCTs) of the testis are the second most common testicular tumours. In the 10 years retrospective study which was done on testicular neoplasms at our institute, this reported case accounted for 0.4%. We are presenting the case of a 30 year old male with a painless testicular swelling. Abdominal ultrasonography disclosed it as a seminoma and the FNAC report was Mixed Germ Cell tumour of the testis. Histopathology concurred the cytological diagnosis and it additionally revealed the concomitant presence of a Yolk Sac Tumour (YST) and a Teratocarcinoma in a Non-Seminomatous Tumour of the testis. This case attains uniqueness with the very rare presence of the yolk sac tumour with the teratocarcinoma component in Non-Seminomatous Testicular Tumours. The reason behind the reporting of the case was its poor therapeutic response.
