World Health Organization guidelines divide GCTs into five types, for which numerous immunohistochemical markers allow exact histological subtyping in the majority of cases. In contrast, a germ cell origin is often hard to prove in metastatic GCTs that have developed so‐called somatic malignant transformation. A high percentage, up to 89%, of GCTs are characterised by the appearance of isochromosome 12p [i(12p)]. Fluorescence in‐situ hybridisation has been the most common diagnostic method for the detection of i(12p) so far, but has the disadvantages of being time‐consuming, demanding, and not being a stand‐alone method. The aim of the present study was to establish a quantitative real‐time polymerase chain reaction assay as an independent method for detecting i(12p) and regional amplifications of the short arm of chromosome 12 by using DNA extracted from formalin‐fixed paraffin‐embedded tissue. Methods and results A cut‐off value to distinguish between the presence and absence of i(12p) was established in a control set consisting of 36 tumour‐free samples. In a training set of 149 GCT samples, i(12p) was detectable in 133 tumours (89%), but not in 16 tumours (11%). In a test set containing 27 primary and metastatic GCTs, all 16 tumours with metastatic spread and/or somatic malignant transformation were successfully identified by the detection of i(12p). Conclusion In summary, the qPCR assay presented here can help to identify, further characterise and assign a large proportion of histologically inconclusive malignancies to a GCT origin."],["dc.description.sponsorship","Wilhelm Sander‐Stiftung http://dx.doi.org/10.13039/100008672"],["dc.identifier.doi","10.1111/his.14258"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/81003"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.relation.eissn","1365-2559"],["dc.relation.issn","0309-0167"],["dc.rights","This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited."],["dc.title","The detection of isochromosome i(12p) in malignant germ cell tumours and tumours with somatic malignant transformation by the use of quantitative real‐time polymerase chain reaction"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

The aim of this study was to develop a diagnostic algorithm using immunohistochemical staining, with a focus on novel markers, and molecular analysis of isochromosome 12p [i(12p)]. Methods and results Paraffin‐embedded tissues of 32 mediastinal tumours were analysed with immunohistochemical staining for sal‐like transcription factor 4 (SALL4), Lin‐28 homologue A (LIN28), octamer‐binding transcription factor 3/4 (OCT3/4), D2‐40, cluster of differentiation 117 (CD117), sex‐determining region Y‐box 17, sex‐determining region Y‐box 2 (SOX2), cluster of differentiation 30, the β‐subunit of human chorionic gonadotropin (β‐hCG), GATA‐binding protein 3 (GATA3), forkhead box protein A2 (FOXA2), glypican‐3 (GPC3), α‐fetoprotein (AFP), terminal deoxynucleotidyl transferase (TdT), nuclear protein of the testis (NUT), and pan‐cytokeratin. Quantitative real‐time polymerase chain reaction was performed to investigate the i(12p) status. Fifteen seminomas, seven teratomas, one yolk sac tumour, one choriocarcinoma and seven mixed PMGCTs were diagnosed. Each entity had different immunohistochemical staining patterns, which helped to distinguish them: OCT3/4, D2‐40, CD117 and TdT for seminoma; OCT3/4 and SOX2 for embryonal carcinoma; FOXA2, GPC3 and AFP for yolk sac tumour; and β‐hCG and GATA3 for choriocarcinoma. Mature teratomas stained positively for pan‐cytokeratin in epithelial components and focally for SALL4, SOX2, GATA3, D2‐40, and FOXA2. Furthermore, a NUT carcinoma mimicking a PMGCT was diagnosed, showing strong nuclear SOX2 staining and speckled nuclear NUT staining. i(12p) was detected in 24 of 27 PMGCTs (89%). Conclusion A diagnostic algorithm is of great importance for a reliable diagnosis of PMGCT in, usually small, tissue biopsy samples. Therefore, a combination of three to four antibodies to identify the correct histological subtype is usually necessary, in addition to morphological features.

So-called somatic type malignancies (i. e. clonally related, non-germ cell neoplasias arising in a GCT) are much more frequent in mGCT than in other organs, and the association between mediastinal yolk sac tumors and hematological malignancies, such as myelodysplasias and leukemias, is unique to mediastinal tumors.

For the correlation between the expression of myoglobin, hypoxia-inducible-factor-la, and capillary density tissue of 86 different renal cell carcinomas were immunohistochemically stained with myoglobin-specific and hypoxia-inducible-factor-1 alpha-specific antibodies as well as with CD31 antibody. Four different renal carcinoma cell lines were cultivated under hypoxic conditions and the expression of myoglobin and hypoxia-induciblefactor-1 alpha was evaluated by real-time PCR and Western blot. Renal cell carcinoma including clear cell, papillary, and chromophobe subtypes expressed myoglobin with an inverse relationship to capillary density being highly significant for clear cell renal cell carcinoma For hypoxiainducible-factor-1 alpha a significant correlation with capillary density could also be observed in clear cell RCC.

Estrogen receptor-beta (ERβ) binds the testosteronemetabolites 3β-androstanediol and 3α-androstanediol in parallel to the canonical estradiol. In the prostate it is widely accepted that ERβ regulates estrogen signalling, mediating anti-proliferative effects. We used the prostate cancer cell lines LNCaP, PC-3, VCaP, and the non-neoplastic BPH-1. VCaP cells were treated with 1 nmol/L testosterone over 20 passages, yielding the cell line VCaPrev, sensitive to hormone therapies. In contrast, LNCaP cells were grown for more than 100 passages yielding a high passage therapy resistant cell line (hiPLNCaP). VCaP and hiPLNCaP cell lines were treated with 5 μmol/L AA for more than 20 passages, respectively, generating the AAtolerant- subtypes VCaPAA and hiPLNCaPAA. Cell lines were treated with testosterone, dihydrotestosterone (DHT), R1881, and the androgen-metabolites 3β-androstanediol and 3α-androstanediol. 3β-androstanediol or 3α-androstanediol significantly reduced proliferation in all cell lines except the BPH-1 and androgen receptor-negative PC-3 and markedly downregulated AR and estrogen receptor alpha (ERα). Whereas ERβ expression was increased in all cell lines except BPH-1 or PC-3. In summary, 3β-adiol or 3α-adiol, as well as DHT and R1881, significantly reduced tumour cell growth in CRPC cells. Thus, these compounds represent novel potential therapeutic approaches to overcome drug-resistance in CRPC, especially with regard to AR-V7 function in therapy resistance. Furthermore, these data confirm the tumour suppressor properties of ERβ in CRPC."],["dc.identifier.doi","10.18632/oncotarget.24763"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15104"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59207"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","1949-2553"],["dc.rights","CC BY 3.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/3.0"],["dc.subject.ddc","610"],["dc.title","Testosterone metabolites inhibit proliferation of castration- and therapy-resistant prostate cancer"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
