CA9‐Targeted PET Imaging for Noninvasive Discrimination of Clear Cell Renal Cell Carcinoma and Associated Tumor Biological Features

open access: yesAdvanced Science, EarlyView.
CA9‐targeted PET imaging could be a noninvasive approach to characterize clear cell renal cell carcinoma and associated tumor biology. PET uptake correlates with tumor CA9 expression and is linked to angiogenic activity, immune remodeling, and metabolic reprogramming.

Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

open access: yesAdvanced Science, EarlyView.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Testosterone and Sarcopenia

open access: yesThe World Journal of Men's Health, 2018
Aging affects metabolism, leading to physiological and functional impairments, and is also related to changes in body composition, including reduced skeletal muscle mass and increased body fat. These changes are correlated with the pathophysiology of sarcopenia, which is defined as age-related loss of skeletal muscle mass and strength. Low testosterone

Expanded Phenotype Associated With an Intronic PPP1R12A Variant: A Case Report and Literature Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Autosomal dominant PPP1R12A‐related genitourinary and/or brain malformation syndrome is a recently described multisystem disorder caused by loss‐of‐function variants in the protein phosphatase 1 regulatory subunit 12a (PPP1R12A) gene. To date, 22 affected individuals have been reported with variable brain malformations and genitourinary ...

Low Testosterone and Sperm Quality Alterations: A Prospective Study of Sperm DNA Fragmentation and Chromatin Condensation in Infertile Men

open access: yesBiology
(1) Background: Testosterone plays a key role in spermatogenesis and in maintaining semen quality and sperm DNA integrity. Consequently, reduced testosterone levels may disrupt these processes and contribute to male infertility.

Sex Hormone Binding Globulin Modifies Testosterone Action and Metabolism in Prostate Cancer Cells

open access: yesInternational Journal of Endocrinology, 2016
Sex Hormone Binding Globulin (SHBG) is the major serum carrier of sex hormones. However, growing evidence suggests that SHBG is internalised and plays a role in regulating intracellular hormone action.

Variation in circulating testosterone during mating predicts reproductive success in a wild songbird.

open access: yesFrontiers in Ecology and Evolution, 2016
Testosterone is an important sex hormone and mediates reproduction in male vertebrates. There is ample evidence that testosterone coordinates the expression of physiological, morphological and behavioural traits during reproduction and many of these ...

Testosterone-induced acute vascular responses.

open access: yes, 2019
(A) Acute testosterone application resulted in increased vasoconstriction in the ACA of female rats subjected to combined VDD and hyperandrogenism (T♀D-) (*p = 0.015 and 0.016 vs. ♀D+ for 10−7 and 10−6 mol/L concentration, respectively; #p = 0.024 vs. ♀D-

A Novel NR3C1 Frameshift Variant Associated With Familial Glucocorticoid Resistance Syndrome: An Integrated Analysis of Steroid Profiling and Structural Modeling

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Glucocorticoid resistance syndrome (GRS) is a rare hereditary disorder caused by pathogenic variants in NR3C1, characterized by marked phenotypic heterogeneity and frequent misdiagnosis as primary aldosteronism or subclinical Cushing's syndrome.

Sex-Specific Associations of Testosterone With Metabolic Traits

open access: yesFrontiers in Endocrinology, 2019
Background: Testosterone levels are differentially linked with diabetes risk in men and women: lower testosterone levels in men and higher testosterone levels in women are associated with type 2 diabetes, though, the mechanisms are not fully clear.
