Temperature manipulation stimulates gonadal maturation and sex steroid production in Senegalese sole Solea senegalensis Kaup kept under two different light regimes

, 2008
This study evaluates the influence of temperature manipulation on circulating levels of sex steroids and gonadal maturation in F1 generation Senegalese sole Solea senegalensis breeders kept under either continuous light (LL) or natural photoperiod (NP ...

Steroidogenic Factor 1 (SF1) Immunohistochemical Stain Is Sensitive and Specific for the Cytopathologic Identification of Intrapancreatic Ectopic Splenic Tissue

Diagnostic Cytopathology, EarlyView.
ABSTRACT Background Accessory spleens result from failure of splenic fusion during development and are occasionally located in the pancreatic tail, radiographically appearing as solid or solid/cystic lesions. Fine needle aspiration (FNA) easily identifies accessory spleens in most samples based on architecture and using CD8 to highlight splenic ...

Integrative analysis of single-nucleus RNA-seq and bulk RNA-seq reveals germline cells development dynamics and niches in the Pacific oyster gonad

iScience
Summary: Gametogenesis drives the maturation of germ cell precursors into functional gametes, facilitated by interactions with the niche environment. However, the molecular mechanisms, especially in invertebrates, remain incompletely understood.

Ontogeny of RSPO1, FOXL2, and RUNX1 during ovarian differentiation in the marsupial tammar wallaby

Developmental Dynamics, EarlyView.
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.

Analyses of the development and glycoproteins present in the ovarian follicles of Poecilia vivipara (Cyprinodontiformes, Poeciliidae)

Pesquisa Veterinária Brasileira, 2011
The morphofunctional aspects of oogenesis of Poecilia vivipara were studied aiming to understand the reproductive biology and development of species with internal fertilization, particularly those belonging to the family Poeciliidae.

The β integrin modulates serotonin sensitivity via NPxY motifs to regulate egg laying and mechanosensation behaviors in Caenorhabditis elegans

Developmental Dynamics, EarlyView.
Abstract Background Integrin is an αβ heterodimeric receptor to the extracellular matrix; its binding to the matrix recruits focal adhesions to two NPxY motifs, the tyrosine phosphorylation sites in the cytoplasmic domain. Studies found that replacing tyrosines (Y) with phenylalanines (F) in the motif of β1 integrin displayed little developmental or ...

Ultrastructural changes in female hepatocytes during ovarian maturation of Steindachnerina insculpta (Pisces: Curimatidae) Mudanças ultra-estruturais nos hepatócitos de fêmeas de Steindachnerina insculpta (Pisces: Curimatidae) durante a maturação ovariana

Brazilian Journal of Biology, 2006
During gonadal maturation the females of Steindachnerina insculpta, a teleost of the Furnas reservoir, Minas Gerais, Brazil, show low hepatosomatic and high gonadossomatic indexes, suggesting possible transference of hepatic substances to the ovaries. In

Enemy release: loss of parasites in invasive freshwater bivalves Sinanodonta woodiana and Corbicula fluminea

Ecography, EarlyView.
Invasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment.
