Non-pulmonary visceral metastases, in bones, brain and liver, represent nearly the 10% of metastatic sites of advanced germ cell tumors and are associated with poor prognosis. This review article summarizes major evidences on the impact of different visceral sites on the prognosis, treatment and clinical outcome of patients with germ cell tumors. The clinic-biological mechanisms by which these metastatic sites are associated with poor clinical outcome remain unclear. The multimodality treatment showed a potential better survival, in particular in patients with relapsed disease. Patients with advanced germ cell tumors with visceral metastases should be referred to centers with high expertise in the clinical management of such disease.

The mammalian Y chromosome is essential for male fertility, but which Y genes regulate spermatogenesis is unresolved. We addressed this by generating 13 Y-deletant mouse models. In , , and deletants, spermatogenesis was impaired.

Background: Central nervous system (CNS) tumors lead to cancer-related mortality in children. Genetic ancestry-associated cancer prevalence and outcomes have been studied, but is limited.
Methods: We performed genetic ancestry prediction in 1,452 pediatric patients with paired normal and tumor whole genome sequencing from the Open Pediatric Cancer (OpenPedCan) project to evaluate the influence of reported race and ethnicity and ancestry-based genetic superpopulations on tumor histology, molecular subtype, survival, and treatment.

The Lepidopteran pest Trichoplusia ni and the parasitoid wasp Trichogramma brassicae represent a fascinating biological system, important for sustainable agricultural practices but challenging to observe. We present a nondestructive method based on micro-CT scanning technology (CT: computed tomography) for visualizing the internal parts of caterpillar embryos and of emerging parasitoids from infected eggs. Traditional methods of microscopic observation of the opaque egg contents require staining or dissection.

Aims: Childhood cancer is a risk factor for cardiovascular diseases in later life. Retinal examination allows to non-invasively observe the vasculature of an end-organ. We observe alterations in long-term childhood cancer survivors (CCS).

Primordial germ cells (PGCs) play a crucial role in transmitting genetic information to the next-generation. In chickens, genetically edited PGCs can be propagated and subsequently transplanted into recipient embryos to produce offspring with desired genetic traits. However, during early embryogenesis, the effects of external conditions on PGC migration through the vascular system to the gonads have yet to be explored, which may affect the efficiency of preparing gene-edited chickens.
