Histological and transcriptomic effects of 17α-methyltestosterone on zebrafish gonad development

BMC Genomics, 2017
Background Sex hormones play important roles in teleost ovarian and testicular development. In zebrafish, ovarian differentiation appears to be dictated by an oocyte-derived signal via Cyp19a1a aromatase-mediated estrogen production.

FOXL2 and DMRT1L Are Yin and Yang Genes for Determining Timing of Sex Differentiation in the Bivalve Mollusk Patinopecten yessoensis

Frontiers in Physiology, 2018
Sex determination and differentiation have long been a research hotspot in metazoans. However, little is known about when and how sex differentiation occurs in most mollusks. In this study, we conducted a combined morphological and molecular study on sex

ATRX and sex differentiation

Trends in Endocrinology & Metabolism, 2004
Most interest in the gene encoding the alpha-thalassemia, mental retardation, X-linked protein (ATRX) has traditionally been focused on its role in brain development and globin regulation. However, mutations in the ATRX gene also cause varying degrees of gonadal and urogenital abnormalities. These range from small testes to ambiguous external genitalia

Long-Term Follow-Up of Patients with 46,XY Partial Gonadal Dysgenesis Reared as Males

International Journal of Endocrinology, 2014
Background/Aims. Studies on 46,XY partial gonadal dysgenesis (PGD) have focused on molecular, gonadal, genital, and hormone features; little is known about follow-up. Our aim was to analyze long-term outcomes of PGD. Methods.

UBE2I stimulates female gonadal differentiation in chicken (Gallus gallus) embryos

Journal of Integrative Agriculture, 2021
Without known analogous sex-determining factors like SRY (sex determining region Y) in mammals, the chicken (Gallus gallus) sex determination mechanism still remains unclear, which highly restricts the biological research on chicken development and ...

Comparative transcriptome analysis reveals differentially expressed genes and signaling pathways between male and female mature gonads of Hemibarbus maculatus

Journal of the World Aquaculture Society, 2023
Hemibarbus maculatus is a globally important species for its value in fisheries and aquaculture. There is relatively little information available about this species' sexual development genes.

A clinical approach to diagnosis of ambiguous genitalia

Journal of Indian Association of Pediatric Surgeons, 2019
Disorders of sex development (DSD) are a sensitive and stressful condition for the family as well as the treating physician to deal with. The main issue in managing such cases is sex assignment.

Can Individuals with 47,XYY Karyotypes Exist without Male Phenotype? A Narrative Literature Review and Case Report

Frontiers in Bioscience-Scholar
Background: The 47,XYY syndrome is a genetic condition found in about 1 in 1000 male children. The expected phenotype is male but could vary greatly.

Differential Expression of miRNAs, lncRNAs, and circRNAs between Ovaries and Testes in Common Carp (Cyprinus carpio)

Cells, 2023
Female common carp grow faster than male individuals, implying that rearing females could be more profitable in aquaculture. Non-coding RNAs (ncRNAs) serve as versatile regulators with multiple functions in diverse biological processes.

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.
