Proteomic Profiling Using a Proximity Extension Assay Panel on Serum Samples Stored at −25°C Over Several Decades

PROTEOMICS, EarlyView.
ABSTRACT The advent of proteomics assays that provide accurate levels of thousands of proteins from relatively small sample volumes opens possibilities for biomarker research in biobanks with valuable samples. In this study, we leverage the applicability of the Olink proximity extension assay to profile serum samples of the Janus Serum Bank, which have

A Sertoli-Leydig ovarian tumor presenting as ovarian torsion: A case report

Case Reports in Women's Health
Torsion occurs as a complication in 10% of cases of ovarian tumors. It predominantly occurs in benign ones, while malignant tumors are less prone to torsion.

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

Effects of FSH on testicular mRNA transcript levels in the hypogonadal mouse [PDF]

, 2009
Follicle stimulating hormone (FSH) acts through the Sertoli cell to ensure normal testicular development and function. To identify transcriptional mechanisms through which FSH acts in the testis we have treated gonadotrophin-deficient hypogonadal (hpg ...

Effects of hypocholesterolemia and chronic hormonal stimulation on sterol and steroid metabolism in a Leydig cell tumor.

Journal of Lipid Research, 1981
The studies presented herein were done to investigate the effects of drug-induced hypocholesterolemia and chronic hormonal stimulation on cholesterol metabolism and steroid biosynthesis in a functional Leydig cell tumor. It was found that 4-aminopyrazolo(

Semen quality in patients with testicular cancer is associated with age and with greatly elevated levels of beta human chorionic gonadotropin

Andrology, EarlyView.
Abstract Background Poor semen quality is a well‐known feature in patients with testicular germ cell tumours (GCTs) at the time of diagnosis but the underlying biological reasons are incompletely understood. Objectives This study aimed to identify GCT‐specific clinical factors that are involved with poor semen quality in GCT patients.

Bilateral Leydig cell tumor in stallion

, 2007
The authors report a rare case of bilateral Leydig cell tumor in a noncryptorchid stallion, describing the gross. and microscopic findings. An 8-year-old Appaloosa stallion was examined for a unilateral enlargement of the testis associated with ...

Identification of MEF2A, MEF2C, and MEF2D interactomes in basal and Fsk‐stimulated mouse MA‐10 Leydig cells

Andrology, EarlyView.
Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.

Imatinib mesylate inhibits Leydig cell tumor growth: Evidence for in vitro and in vivo activity

, 2005
Leydig cell tumors are usually benign tumors of the male gonad. However, if the tumor is malignant, no effective treatments are currently available.

True Precocious Puberty Following Treatment of a Leydig Cell Tumor. Two Case Reports and Literature Review [PDF]

, 2015
Leydig cell testicular tumors are a rare cause of precocious pseudopuberty in boys. Surgery is the main therapy and shows good overall prognosis. The physical signs of precocious puberty are expected to disappear shortly after surgical removal of the ...
