Adrenocortical adenomas and carcinomas in other parenchyma are extremely rare, with few cases reported and because of the rarity of these tumors, they occasionally cause problems during diagnosis. Adrenal cortical neoplasms in liver parenchyma can be present in 3 forms, including direct invasion or adhesion to liver parenchyma, tumors arising in adrenohepatic fusion tissue or in ectopic adrenal gland tissue. We report 3 cases of adrenal cortical tumors that were misdiagnosed as hepatocellular carcinoma in the preoperative state...

Early-life stress is an established risk for the development of psychiatric disorders. Post-weaning isolation rearing of rats produces lasting developmental changes in behavior and brain function that may have translational pathophysiological relevance to alterations seen in schizophrenia, but the underlying mechanisms are unclear. Accumulating evidence supports the premise that gut microbiota influence brain development and function by affecting inflammatory mediators, the hypothalamic-pituitary-adrenal axis and neurotransmission, but there is little knowledge of whether the microbiota-gut-brain axis might contribute to the development of schizophrenia-related behaviors...

PURPOSE OF REVIEW: Germline pathogenic TP53 mutation may predispose to multiple cancers but penetrance and cancer patterns remain incompletely documented. We have analyzed international agency for research on cancer TP53 database to reevaluate age and variant-dependent tumor patterns. RECENT FINDINGS: Genome-wide studies suggest that germline variants are more frequent than estimated prevalence of Li-Fraumeni syndrome (LFS), suggesting that many carriers of potentially pathogenic mutations may not develop the syndrome...

Adrenal collision tumors (ACTs), in which distinct tumors coexist without histological intermingling in the same adrenal gland, are rare and their actual prevalence is unknown. ACTs commonly consist of adrenal cortical adenoma, myelolipoma, or metastatic malignant tumor. We report a 58-year-old woman with a past history of breast cancer, who presented with a 1 month history of fevers, chills, and abdominal fullness. The physical examination and the laboratory data including endocrine studies were unremarkable...

Antenatal maternal depressive symptoms influence fetal brain development and increase the risk for depression in offspring. Such vulnerability is often moderated by the offspring's genetic variants. This study aimed to examine whether FKBP5, a key regulator of the hypothalamic-pituitary-adrenal (HPA) axis, moderates the association between antenatal maternal depressive symptoms and in utero brain development, using an Asian cohort with 161 mother-offspring dyads. Antenatal maternal depressive symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS) during the second trimester of pregnancy...

Chronic stress-associated pathologies frequently associate with alterations in the structure and activity of the medial prefrontal cortex (mPFC). However, the influence of infralimbic cortex (IL) projection neurons on hypothalamic-pituitary-adrenal (HPA) axis activity is unknown, as is the involvement of these cells in chronic stress-induced endocrine alterations. In the current study, a lentiviral-packaged vector coding for a small interfering RNA (siRNA) targeting vesicular glutamate transporter (vGluT) 1 messenger RNA (mRNA) was microinjected into the IL of male rats...

P M O'Shea, T P Griffin, G A Browne, N Gallagher, J J Brady, M C Dennedy, M Bell, D Wall, M Fitzgibbon
BACKGROUND: The recommended approach to screening for primary aldosteronism (PA) in at-risk populations is to determine the ratio of aldosterone concentration (serum (SAC)/plasma (PAC)) to renin measured in plasma as activity (PRA) or concentration (DRC). However, lack of assay standardisation mandates the need for method-specific decision thresholds and clinical validation in the local population. AIM: The study objective was to establish method-specific aldosterone: renin ratio (ARR) cut-offs for PA in men and women using the IDS-iSYS® assay system (IDS plc)...

BACKGROUND: Advances in cancer therapeutics depend on reliable in vivo model systems. To develop biologically relevant xenografts, ultrasound was utilized for tissue-directed implantation of neuroblastoma (NB) cell line and patient-derived tumors in the adrenal gland, and for renal subcapsular engraftment of Ewing's sarcoma (ES). MATERIALS AND METHODS: NB xenografts were established by direct adrenal injection of luciferase-transfected NB cell lines (IMR32, SH-SY5Y, SK-N-BE2) or NB patient-derived tumor cells (UMNBL001, UMNBL002)...

The diagnosis of low-grade adrenal cortical carcinoma (ACC) confined to the adrenal gland can be challenging. Although there are diagnostic and prognostic molecular tests for ACC, they remain largely unutilized. We examined the diagnostic and prognostic value of altered reticulin framework and the immunoprofile of biomarkers including IGF-2, proteins involved in cell proliferation and mitotic spindle regulation (Ki67, p53, BUB1B, HURP, NEK2), DNA damage repair (PBK, γ-H2AX), telomere regulation (DAX, ATRX), wnt-signaling pathway (beta-catenin) and PI3K signaling pathway (PTEN, phospho-mTOR) in a tissue microarray of 50 adenomas and 43 carcinomas that were characterized for angioinvasion as defined by strict criteria, Weiss score, and mitotic rate-based tumor grade...

Chronic stress is considered a widely accepted risk factor for the development of neuropsychiatric and neurological disorders. Indeed, high cortisol levels, and, thus, hypothalamic pituitary adrenal (HPA)-axis dysregulation, have been indicated as the most frequent alteration in patients affected by depression, as well as by Alzheimer's disease (AD). Furthermore, depressive state has been pointed as an early manifestation of AD, advocating an overlap between these neuropathological events. We have previously demonstrated that central soluble beta amyloid 1-42 (Aβ) administration peptide induces a depressive like-behavior in rats, with altered HPA axis activation, reduced cortical serotonin and neurotrophin levels...

Hypoxia or intermittent hypoxia (IH) have known to alter both synthesis and secretion of hormones. However, the effect of IH on the production of adrenal cortical steroid hormones is still unclear. The aim of present study was to explore the mechanism involved in the effect of IH on the production of corticosterone by rat ZFR cells. Male rats were exposed at 12% O2 and 88% N2 (8 hours per day) for 1, 2, or 4 days. The ZFR cells were incubated at 37 °C for 1 hour with or without ACTH, 8-Br-cAMP, calcium ion channel blockers, or steroidogenic precursors...

Adrenal cortical hyperplasia manifests radiologically as a non-malignant growth, or enlargement, of the adrenal glands, specifically the cortex, although the cortex cannot be definitively identified by conventional imaging. Controlled by the pituitary gland, the adrenal cortex drives critical processes, such as the production of cortisol, mineralocorticoid and sex hormones. Any disruption in the multiple enzymes and hormones involved in these pathways may cause serious or life-threatening symptoms, often associated with anatomical changes in the adrenal glands...

Corticotropin releasing hormone (CRH) produced by the hypothalamus initiates the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the body's stress response. CRH levels typically are undetectable in human plasma, but during pregnancy the primate placenta synthesizes and releases large amounts of CRH into both maternal and fetal circulations. Notably, placental CRH synthesis increases in response to maternal stress signals. There is evidence that human fetal exposure to high concentrations of placental CRH is associated with behavioral consequences during infancy and into childhood, however the direct effects on of the peptide on the human brain are unknown...
