Eliminating SF-1 (NR5A1) sumoylation in vivo results in ectopic hedgehog signaling and disruption of endocrine development.

Sumoylation is generally considered a repressive mark for many transcription factors. However, the in vivo importance of sumoylation for any given substrate remains unclear and is questionable because the extent of sumoylation appears exceedingly low for most substrates. Here, we permanently eliminated SF-1/NR5A1 sumoylation in mice (Sf-1(K119R, K194R, or 2KR)) and found that Sf-1(2KR/2KR) mice failed to phenocopy a simple gain of SF-1 function or show elevated levels of well-established SF-1 target genes. Instead, mutant mice exhibited marked endocrine abnormalities and changes in cell fate t

Neonatal xenoestrogen exposure alters growth hormone-dependent liver proteins and genes in adult female rats.

The hypothalamic-growth hormone (GH)-liver axis represents a new concept in endocrine regulation of drug toxicity. Preponderant sex differences are found in liver gene expression, mostly dependent on the sexually dimorphic pattern of GH secretion which is set during the neonatal period by gonadal steroids. We tested if GH-dependent sexually dimorphic liver enzymes and proteins was perturbed by neonatal Bisphenol A (BPA) treatment in female rats. Female rats were sc injected with BPA (50 or 500 μg/50 μl) or castor oil vehicle from postnatal day 1 to 10. At five months serum prolactin, pituitary

Xerostomia due to systemic disease: a review of 20 conditions and mechanisms.

Xerostomia is a common complaint of nearly half of the elderly population and about one-fifth of younger adults. It causes several signs and symptoms, and compromise oral functions and health-related quality-of-life. Multiple reasons are proposed to describe the etiology of xerostomia such as local factors, psychogenic factors, and systemic diseases. In order to manage xerostomia effectively, identification of the main causality is mandatory. The aim of this review was to present systemic diseases leading to xerostomia with their mechanisms of action. We used various general search engines and

Infiltrative and inflammatory systemic disorders involving the pituitary gland.

The hypothalamic-pituitary region can be affected by a wide and heterogeneous group of infiltrative and inflammatory disorders, including granulomatous, histiocytic, storage, infectious, non-pituitary neoplastic, and autoimmune or inflammatory conditions collectively grouped as hypophysitis. Although individually rare, these disorders are increasingly recognized due to growing awareness, wider use of pituitary imaging, and the emergence of immune checkpoint inhibitor-induced hypophysitis. They typically present with hypopituitarism (often including arginine vasopressin deficiency, which, parti

Pituitary metastasis: a rare condition.

Tumor metastasis to the pituitary gland is a rare, not well-documented and life-threatening condition associated with a shortened life span. A better understanding of its clinical manifestations could lead to earlier diagnosis, appropriate therapy and potentially improving quality of life. Therefore, we retrospectively studied the charts of patients with pituitary metastases who were treated at the City of Hope National Medical Center (Duarte, CA) from 1984 to 2018. We reviewed and analyzed tumor origin, primary pituitary clinical manifestation, duration between primary tumor diagnosis and pit

Characteristics of Immune-Related Thyroid Adverse Events in Patients Treated with PD-1/PD-L1 Inhibitors.

BACKGROUND: Thyroid immune-related adverse events (IRAEs) have been reported in patients treated with programmed cell death protein-1 (PD-1) and programmed cell death protein-ligand 1 (PD-L1) inhibitors. We investigated the incidence and clinical course of PD-1/PD-L1 inhibitor-induced thyroid IRAEs, and identified predictable clinical risk factors of thyroid IRAEs, in particular, overt hypothyroidism (OH). METHODS: We retrospectively reviewed the medical records of 325 cancer patients receiving PD-1/PD-L1 inhibitor in a tertiary referral center. RESULTS: A total of 50.5% (164/325) of patient

From Cellular Stress to Systemic Adaptation: The Circadian Clock and Stress Response at Cellular and Systemic Levels.

The stress response is essential for cellular and organismal survival as it acts as a protective and adaptive mechanism to maintain homeostasis. At the organismal level, physical stressors induce responses in mammals that are mediated primarily by the hypothalamic-pituitary-adrenal (HPA) axis, which regulates glucocorticoid secretion. The HPA axis functions as a circadian-regulated, multi-oscillator system, in which the paraventricular nucleus, the pituitary, and the adrenal gland exhibit intrinsic rhythmicity while remaining coordinated by the output from the suprachiasmatic nucleus. Glucocor

Obesity, inflammation, and cancer in dogs: Review and perspectives.

Obesity is the most common nutritional disease in dogs, and its prevalence has increased in recent decades. Several countries have demonstrated a prevalence of obesity in dogs similar to that observed in humans. Chronic low-grade inflammation is a prominent basis used to explain how obesity results in numerous negative health consequences. This is well known and understood, and recent studies have pointed to the association between obesity and predisposition to specific types of cancers and their complications. Such elucidations are important because, like obesity, the prevalence of cancer in

The Rise of Oncoendocrinology: How Modern Cancer Therapies Are Reshaping Endocrine Practice.

The emergence of immune checkpoint inhibitors, targeted therapies, CAR T-cell therapy, and antibody-drug conjugates has transformed modern oncology, significantly improving survival across a wide range of malignancies. However, these advances have also introduced a growing spectrum of endocrine and metabolic complications, redefining the scope of endocrine practice. Therapy-induced endocrinopathies, including thyroid dysfunction, hypophysitis, adrenal insufficiency, diabetes, pancreatitis, dyslipidemia, gonadal dysfunction, and metabolic syndrome, are recognized as clinically significant and o

Pituitary metastasis: a clinical overview.

The pituitary gland is an unusual site for metastatic spread and has been associated with a poor prognosis. Clinical presentation is variable but can include visual field defects, cranial nerve palsies, anterior pituitary dysfunction and/ or diabetes insipidus. Management options include surgery or radiotherapy, chemotherapy/immunotherapy or a conservative approach. The pituitary should not be overlooked as a site for metastasis in patients with known cancer and can be the first presentation of neoplastic disease in some patients. Given that patients are now living longer with cancer, clinicia

Treating Primary Aldosteronism-Induced Hypertension: Novel Approaches and Future Outlooks.

Primary aldosteronism (PA) is the most common cause of secondary hypertension and is associated with increased morbidity and mortality when compared with blood pressure-matched cases of primary hypertension. Current limitations in patient care stem from delayed recognition of the condition, limited access to key diagnostic procedures, and lack of a definitive therapy option for nonsurgical candidates. However, several recent advances have the potential to address these barriers to optimal care. From a diagnostic perspective, machine-learning algorithms have shown promise in the prediction of P

Oral and Maxillo-Facial Manifestations of Systemic Diseases: An Overview.

Many systemic (infective, genetic, autoimmune, neoplastic) diseases may involve the oral cavity and, more generally, the soft and hard tissues of the head and neck as primary or secondary localization. Primary onset in the oral cavity of both pediatric and adult diseases usually represents a true challenge for clinicians; their precocious detection is often difficult and requires a wide knowledge but surely results in the early diagnosis and therapy onset with an overall better prognosis and clinical outcomes. In the current paper, as for the topic of the current Special Issue, the authors pre

A Rare Case of Systemic Amyloidosis Involving the Thyroid in a Young Patient.

Thyroid amyloidosis is a rare condition associated with thyroid pathologies such as medullary carcinoma, papillary carcinoma, amyloid goitre, and benign lesions, with a clinically palpable goitre being exceptionally uncommon. As a result, many cases of benign thyroid enlargement caused by amyloid deposits remain undiagnosed. A 28-year-old male patient noticed progressive neck circumference enlargement, voice alteration, decreased appetite, weight loss, dysphagia, fever, and night sweats. Fine-needle aspiration biopsy of the thyroid gland did not reveal the cause of the goitre. A total thyroide
