Ejaculate Investment in a Promiscuous Rodent, \u3cem\u3ePeromyscus maniculatus\u3c/em\u3e: Effects of Population Density and Social Role [PDF]
Questions: How does average male investment in ejaculates vary with changing population density (and thus with the risk of sperm competition) in a promiscuous species? Do individual male investment strategies vary with population density?

Dynamic expression of lamin B1 during adult neurogenesis in the vertebrate brain
Abstract Background In mammals, specific brain regions such as the dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles harbor adult neural stem/progenitor cells (ANSPCs) that give rise to new neurons and contribute to structural and functional brain plasticity.

A microRNA cluster in the Fragile-X region expressed during spermatogenesis targets FMR1. [PDF]
Testis-expressed X-linked genes typically evolve rapidly. Here, we report on a testis-expressed X-linked microRNA (miRNA) cluster that despite rapid alterations in sequence has retained its position in the Fragile-X region of the X chromosome in ...

Ontogeny of RSPO1, FOXL2, and RUNX1 during ovarian differentiation in the marsupial tammar wallaby
Abstract Background RSPO1 and FOXL2 are female sex‐determining genes involved in the differentiation and organization of the ovary in some eutherian mammals. Mutations or loss of function of these genes are associated with partial to full sex reversal in mice, humans, and goats.

Deregulated enhancer‐promoter communication in cancer through altered nuclear architecture
Abstract Enhancers are critical regulators of gene expression. Structural variations in cancer genomes can lead to enhancer hijacking, where oncogenes are activated by mistargeted enhancer activity. Novel enhancer‐promoter interactions may also arise through chromosomal rearrangements that create extrachromosomal DNA elements.

What's New? Currently, no published data on homologous recombination deficiency (HRD) testing in the setting of molecular tumor boards exist. This study in a cohort of 237 patients encompassing 24 different tumor entities assessed by a molecular tumor board shows that inactivating alterations of BRCA1/2 are not always associated with an elevated ...

What's New? Immune suppression induced by HIV infection significantly increases the risk of certain cancers among people with HIV (PWH). In the present study, the authors investigated cancer incidence among HIV‐infected individuals in Italy using data from the Italian Cohort Naïve Antiretrovirals. Comparison with the corresponding general population in

Pregnancy via Testicular Sperm Extraction for Anejaculation After Neuroblastoma Surgery
ABSTRACT Background Surgical treatment of a neuroblastoma, a malignant tumor of the sympathetic nervous system, may result in ejaculatory disorder. There are no reports examining ejaculation disorders after neuroblastoma surgery. Case Presentation The patient was a 31‐year‐old Japanese male who had undergone surgery for neuroblastoma of the abdomen at ...
