Early precursor-derived pituitary gland tissue-resident macrophages play a pivotal role in modulating hormonal balance [scRNA-Seq]

ABSTRACT: Macrophages were identified in the pituitary gland long ago, but until recently, we lacked the resolution to comprehensively profile the pituitary gland macrophage compartment. To address this, we examined the developmental kinetics and distinctive characteristics of pituitary macrophages within the developing and homeostatic gland. Whole pituitary glands were collected from newborn (NB) to adult (8 weeks old) wild-type (WT) mice. Our analysis revealed diverse macrophage subsets with marked differences in gene expression profiles and spatial localization, undergoing dynamic phenotypic changes from neonatal stages to adulthood. We observed distinct transcriptional profiles between macrophage subpopulations in the anterior and posterior lobes, underscoring significant molecular divergences. Fate-mapping analyses showed that pituitary macrophages originate from early yolk sac precursors and persist throughout life primarily through local proliferation, even under pathophysiological conditions.

Proteomic analysis of human anterior pituitary gland

Project description:The regulation of pituitary function via the hypothalamus and via intra-pituitary connections represents a complex system. Though hormones secreted from the pituitary glands have been well studied, overall information of proteins expressed in the pituitary glands is very limited. Protein expression profiling of normal pituitary tissue may lead to discovery of novel proteins playing an important role in the physiology of pituitary glands and can lead to better understanding of pituitary gland diseases. We aimed to carry out systematic proteomic profiling of adenohypophysis from human pituitary glands using high-resolution Fourier transform mass spectrometer. A total of 2,175 proteins were identified in this study of which, 105 proteins were identified for the first time as compared to high throughput proteomic-based studies from human pituitary glands. The comprehensive list of proteins identified in this study will facilitate the better understanding the role of this important gland in health and disease.

The Effect of Monoclonal Vascular Endothelial Growth Factor (VEGF) Antibody (Bevacizumab) on Pituitary Function

Project description:The purpose of this research is to determine whether the drug, Bevacizumab (a monoclonal anti VEGF-A antibody), which is approved to treat patients with metastatic colon cancer induces hyperprolactinemia (increased prolactin secretion) in humans with intact pituitary function. Past studies have shown Bevacizumab to shrink tumor size and also increase prolactin levels. The mechanism of the hyperprolactinemia might be inhibition of pituitary portal vein transport, suggesting that Bevacizumab induces prolactin secretion from normal lactotrophs in the pituitary gland. Patients who have been treated with Bevacizumab for at least one month will be recruited to participate. The subjects who are being treated with Bevacizumab by Dr. Stephen Wolin (a sub-investigator) will be screened by him for study eligibility. Dr. Wolin will approach eligible patients with all the information and background of the study and see if they have an interest in being consented. If consented, there will be 2 blood draws for the research that is not part of their standard care in which 10 ml of blood is collected and prolactin, growth hormone, IGF-I, TSH, thyroxine, ACTH, and cortisol will be measured. One 5ml blood draw will occur before the administration of Bevacizumab and the second 5 ml blood draw will occur after the administration of the Bevacizumab. The investigators will then review the laboratory results. The blood tests are of the hormones of the pituitary gland to test pituitary function and see if there are any abnormalities with the secretions of the gland. Pituitary function abnormalities and hyperprolactinemia are diagnosed by looking at hormone levels in the blood and comparing them to the normal reference ranges. This study will only involve 10 subjects and will be conducted entirely at Cedars-Sinai Medical Center.

The differential gene screening for invasive pituitary adenoma and non-invasive pituitary adenoma

Project description:Pituitary adenomas are benign tumors originating from the endocrine cells of the pituitary gland, but some pathological subtypes are highly invasive, known as invasive pituitary adenomas. Invasive pituitary adenomas are relatively rare, progress rapidly, easily invade surrounding tissues, have a high risk of recurrence, and have poor response to standard treatments. This study collected tumor specimens from 17 patients with non-invasive pituitary adenomas (FSH type) and 15 patients with invasive pituitary adenomas (ACTH-silent type), and performed transcriptome sequencing, aiming to explore the genetic differences between invasive and non-invasive pituitary adenomas.
