Effects of Melatonin on Anterior Pituitary Plasticity: A Comparison Between Mammals and Teleosts [PDF]

Frontiers in Endocrinology, 2021
Melatonin is a key hormone involved in the photoperiodic signaling pathway. In both teleosts and mammals, melatonin produced in the pineal gland at night is released into the blood and cerebrospinal fluid, providing rhythmic information to the whole ...

Investigation of the serum levels of anterior pituitary hormones in male children with autism [PDF]

Molecular Autism, 2011
Background The neurobiological basis of autism remains poorly understood. The diagnosis of autism is based solely on behavioural characteristics because there are currently no reliable biological markers.

Pituitary Stalk Interruption Syndrome: A Case Report

Turkish Journal of Internal Medicine, 2021
Panhypopituitarism occurs as a result of the insufficiency of all hormones produced in the anterior pituitary gland. Pituitary Stalk Interruption Syndrome (PSIS) is a rare congenital syndrome leading to hypopituitarism.

Machine-Learning Prediction of Postoperative Pituitary Hormonal Outcomes in Nonfunctioning Pituitary Adenomas: A Multicenter Study

Frontiers in Endocrinology, 2021
ObjectiveNo accurate predictive models were identified for hormonal prognosis in non-functioning pituitary adenoma (NFPA). This study aimed to develop machine learning (ML) models to facilitate the prognostic assessment of pituitary hormonal outcomes ...

Anterior pituitary hormones in first-episode psychosis: a systematic review and meta-analysis

European Psychiatry, 2023
Introduction Although the role of pituitary gland in schizophrenia and psychotic disorders has been studied for decades, evidence on anterior pituitary hormones in the early phases of psychoses – without the influence of chronicity, comorbidities, and ...

Timing feedback-inhibition of the male reproductive hormone axis [PDF]

, 2008
Hormonal methods of male contraception have addressed feedback-inhbition of the cascade of hormones that has evolved to regulate sperm production but high concentrations of testosterone (T) in the blood have not worked satisfactorily.

Gene Expression and the Physiological Role of Transforming Growth Factor-α in the Mouse Pituitary [PDF]

, 2003
Transforming growth factor-alpha (TGF-alpha), a member of the epidermal growth factor (EGF) family, is produced within the mouse anterior pituitaries. However, the cell types of TGF-alpha-expressing cells and the physiological roles of TGF-a within mouse

Transcriptional profiling and pathway analysis reveal differences in pituitary gland function, morphology, and vascularization in chickens genetically selected for high or low body weight

BMC Genomics, 2019
Background Though intensive genetic selection has led to extraordinary advances in growth rate and feed efficiency in production of meat-type chickens, endocrine processes controlling these traits are still poorly understood. The anterior pituitary gland
