Growth Hormone (GH)-Releasing Peptide Stimulation of GH Release from Human Somatotroph Adenoma Cells: Interaction with GH-Releasing Hormone, Thyrotropin- Releasing Hormone, and Octreotide. [PDF]

open access: yes, 1994
The synthetic hexapeptide GH-releasing peptide (GHRP; His-D-Trp-Ala-Trp-D-Phe-Lys-NH2) specifically stimulates GH secretion in humans in vivo and in animals in vitro and in vivo via a still unknown receptor and mechanism.

Counterbalancing O‐GlcNAcylation and STAT3 Phosphorylation in Ventral Tegmental Area Dopaminergic Neurons Mediates Behavioral Adaptations to Acute Restraint Stress

open access: yesAdvanced Science, EarlyView.
Acute restraint stress enhances STAT3Ser727 phosphorylation in dopaminergic neurons in mice. This modification promotes the upregulation of GABBR2 and GABRB3, reduces neuronal activity, and contributes to anxiety‐like behavior and diminished reward‐seeking following stress exposure.

Corticosterone Contributes to Context‐Triggered Retrieval of Morphine Withdrawal Memories by Acting on Basolateral Amygdala Neurons Projecting to Nucleus Accumbens Core

open access: yesAdvanced Science, EarlyView.
Context associated with morphine withdrawal elicits an increase in serum corticosterone levels. Corticosterone participates in CTR‐MWM by acting on MR, but not GR, in the BLA. MR in BLA→NAcC neurons mediates CTR‐MWM. MR increases presynaptic glutamate release and meanwhile participates in D1 receptor‐induced increases in presynaptic glutamate release ...

The STUB1-TPIT axis regulates the secretion of adrenocorticotrophic hormone in cushing disease

open access: yesJournal of Translational Medicine
Background Cushing’s disease (CD) is a clinical syndrome caused by excessive secretion of adrenocorticotropic hormone (ACTH) from a pituitary corticotroph adenoma, resulting in adrenal cortical hyperplasia and overproduction of cortisol.

Norepinephrine Induces Sertoli Cell Ferroptosis via Receptors Desensitization Causing Stress‐Related Male Reproductive Dysfunction

open access: yesAdvanced Science, EarlyView.
Psychological stress activates the sympathetic–adrenal axis, elevating norepinephrine (NE) and suppressing reproductive hormones, thereby impairing male reproduction. Excess NE overactivates and desensitizes β‐adrenergic receptors (β‐ARs), triggering Sertoli cell ferroptosis and disrupting spermatogenesis.

Cholesterol-activated stress granules reduce the membrane localization of DRD2 and promote prolactinoma dopamine agonists resistance

open access: yesActa Neuropathologica Communications
Prolactinoma is the most prevalent pituitary neuroendocrine tumor and dopamine agonists (DAs) targeting dopamine D2 receptor (DRD2) are recommended as the first-line treatment. However, varying degrees of DA resistance limit patient benefit.

Status of temozolomide use without insurance coverage in patients with aggressive pituitary neuroendocrine tumors

open access: yesEndocrine Journal
The 2017 World Health Organization classification described aggressive pituitary neuroendocrine tumor (PitNET) as “a tumor with strong invasiveness and rapid growth, which is difficult to treat with surgery, radiation therapy, or drug therapy,” which ...

The pituitary TGFb1 system as a novel target for the treatment of resistant prolactinomas [PDF]

open access: yes, 2016
Prolactinomas are the most frequently observed pituitary adenomas and most of themrespond well to conventional treatment with dopamine agonists (DAs).

Cancer Neuroscience: Decoding Neural Circuitry in Tumor Evolution for Targeted Therapy

open access: yesAdvanced Science, EarlyView.
This review highlights the pivotal role of the nervous system in cancer progression, emphasizing how neural–tumor interactions—via synaptic signaling, neurotransmitters, and paracrine factors—reshape the tumor microenvironment. It introduces cancer neuroscience as an emerging field and proposes integrating advanced tools such as AI and optogenetics to ...

Pituitary apoplexy induced by gonadotropin-releasing hormone agonist administration: a rare complication of prostate cancer treatment

open access: yesEndocrinology, Diabetes & Metabolism Case Reports, 2020
Gonadotropin-releasing hormone (GnRH) agonists, currently used in the treatment of advanced prostate cancer, have been described as a rare cause of pituitary apoplexy, a potentially life-threatening clinical condition. We report the case of a 69-year-old
