Characterization of Human Pituitary Adenomas in Cell Cultures by Light And Electron Microscopic Morphology And Immunolabeling [PDF]

, 2005
The morphology and hormone production of pituitary adenoma cell cultures were compared in order to highlight their characteristic in vitro features. Cell suspensions were prepared from 494 surgical specimens.

E2F1 induces pituitary tumor transforming gene (PTTG1) expression in human pituitary tumors.

Molecular Endocrinology, 2009
Rb/E2F is dysregulated in murine and human pituitary tumors. Pituitary tumor transforming gene (PTTG1), a securin protein, is required for pituitary tumorigenesis, and PTTG1 deletion attenuates pituitary tumor development in Rb(+/-) mice.

FSH-producing pituitary neuroendocrine tumor as a cause of ovarian hyperstimulation syndrome

Endocrinology, Diabetes & Metabolism Case Reports
Functioning gonadotroph tumors are rare neoplasms that can cause ovarian hyperstimulation syndrome (OHSS) in women of reproductive age. Here, we present a case of a follicle-stimulating hormone (FSH)-producing pituitary neuroendocrine tumor (PitNET) with

Pituitary tumor apoplexy.

Arquivos de Neuro-Psiquiatria, 2009
Pituitary tumor apoplexy is a medical emergency due to acute infarction or hemorrhage in the pituitary gland. In this review, the authors discuss the sellar anatomy, the pituitary gland and adenomas' vascularization and the general aspects of the ...

No evidence for oncogenic mutations in guanine nucleotide-binding proteins of human adrenocortical neoplasms [PDF]

, 1933
G-Proteins are membrane-bound heterotrimeric polypeptides that couple receptor signals to second messenger systems such as cAMP. Recently, point mutations at 2 codons of the highly preserved alpha-chain of Gs, the adenyl cyclase-stimulating G-protein ...

Light Weight CNN for classification of Brain Tumors from MRI Images [PDF]

arXiv
This study presents a convolutional neural network (CNN)-based approach for the multi-class classification of brain tumors using magnetic resonance imaging (MRI) scans. We utilize a publicly available dataset containing MRI images categorized into four classes: glioma, meningioma, pituitary tumor, and no tumor. Our primary objective is to build a light

Delayed cerebral ischemia associated with surgery for pituitary macroadenomas that express elevated levels of PACAP

Brain Hemorrhages, 2023
Delayed cerebral ischemia (DCI) and cerebral vasospasm (VS) are rare but serious post-operative complications after surgery for pituitary macroadenomas; the mechanism of which are poorly understood.
