Cell division promotes efficient retrotransposition in a stable L1 reporter cell line [PDF]

open access: yes, 2013
Background: Long interspersed element type one (L1) actively modifies the human genome by inserting new copies of itself. This process, termed retrotransposition, requires the formation of an L1 ribonucleoprotein (RNP) complex, which must enter the ...

Germ Cell Tumor Presenting with Precocious Puberty in a Girl in United Arab Emirates

open access: yesDubai Medical Journal, 2020
We herein report a rare case of malignant mixed germ cell tumor comprising both an embryonal carcinoma (60%) and a yolk sac tumor (40%). A 7-year-old girl presented to the emergency department with persistent vaginal bleeding, abdominal pain, and ...

Cripto: expression, epigenetic regulation and potential diagnostic use in testicular germ cell tumors [PDF]

open access: yes, 2016
Type II germ cell tumors arise after puberty from a germ cell that was incorrectly programmed during fetal life. Failure of testicular germ cells to properly differentiate can lead to the formation of germ cell neoplasia in situ of the testis; this ...

Integrated Molecular Characterization of Testicular Germ Cell Tumors

open access: yesCell Reports, 2018
Summary: We studied 137 primary testicular germ cell tumors (TGCTs) using high-dimensional assays of genomic, epigenomic, transcriptomic, and proteomic features. These tumors exhibited high aneuploidy and a paucity of somatic mutations.

Malignant Ovarian Mixed Germ Cell Tumor: a Rare Case [PDF]

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2009
Background and Objectives: Mixed germ cell tumors of the ovary, uncommon but aggressive tumors are seen most often in young women or adolescent girls, and are generally curable if found and treated early.

A Case of Sarcoidosis Disseminated to Skeletal Tissues

open access: yesInternational Journal of Medical Students, 2013
Sarcoidosis is a systemic granulomatous disease of unknown etiology that typically affects young adults. Diagnostic criteria for sarcoidosis include involvement of two or more of the following organ systems: 1) pulmonary infiltrates; 2) bilateral hilar ...

Assessing Homologous Recombination and Interstrand Cross-Link Repair in Embryonal Carcinoma Testicular Germ Cell Tumor Cell Lines

open access: yes, 2020
testicular germ cell tumors (TGCTs) are typically exquisitely sensitive to DNA interstrand cross-link (ICLs) agents. ICLs covalently link both strands of the DNA duplex, impeding fundamental cellular processes like DNA replication to cause cell death.

Formation of neural and epidermal lineages during the differentiation of human embryonal carcinomacells [PDF]

open access: yes, 2003
Within the ectoderm of the developing human embryo, cell fate determination is largely modulated by factors activated by cell-to-cell signalling. In vertebrates, ectoderm primarily differentiates into neural cells that make up the central nervous system ...

Association of intratubular seminoma and intratubular embryonal carcinoma with invasive testicular germ cell tumors

open access: yes, 2007
The classification of intratubular germ cell neoplasia of the testis includes an unclassified type (IGCNU), in addition to various other intratubular lesions that show specific forms of differentiation, such as intratubular seminoma and intratubular ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
