  • Systemic ghrelin treatment induces rapid, transient and asymmetric changes
           in the metabolic activity of the mouse brain

    • Free pre-print version: Loading...

      Abstract: Introduction: Ghrelin regulates a variety of functions by acting in the brain. The targets of ghrelin in the mouse brain have been mainly mapped using immunolabeling against c-Fos, a transcription factor used as a marker of cellular activation, but such analysis has several limitations. Here, we used positron emission tomography in mice to investigate the brain areas responsive to ghrelin. Methods: We analyzed in male mice the brain areas responsive to systemically-injected ghrelin using positron emission tomography imaging of 18F-fluoro-2-deoxyglucose (18F-FDG) uptake, an indicator of metabolic rate. Additionally, we studied if systemic administration of fluorescent-ghrelin or native ghrelin display symmetric accessibility or induction of c-Fos, respectively, in the brain of male mice. Results: Ghrelin increased 18F-FDG uptake in few specific areas of the isocortex, striatum, pallidum, thalamus and midbrain at 0-10-min post-treatment. At the 10-20- and 20-30-min post-treatment, ghrelin induced mixed changes in 18F-FDG uptake in specific areas of isocortex, striatum, pallidum, thalamus and midbrain, as well as in areas of the olfactory areas, hippocampal and retrohippocampal regions, hypothalamus, pons, medulla and even the cerebellum. Ghrelin-induced changes in 18F-FDG uptake were transient and asymmetric. Systemically-administrated fluorescent-ghrelin labeled midline brain areas known to contain fenestrated capillaries and the hypothalamic arcuate nucleus, where a symmetric labeling was observed. Ghrelin treatment also induced a symmetric increased c-Fos labeling in the arcuate nucleus. Discussion/Conclusion: Systemically-injected ghrelin transiently and asymmetrically affects the metabolic activity of the brain of male mice in a wide range of areas, in a food intake independent manner. The neurobiological bases of such asymmetry seem to be independent of the accessibility of ghrelin into the brain.

  • Diagnostic strategy and prognostic factors for ectopic adrenocorticotropic
           hormone syndrome: a retrospective study of 64 cases

    • Free pre-print version: Loading...

      Abstract: Introduction: Ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS) is a serious life-threatening disease. Tumor localization is crucial in EAS management. This underscores the importance of evaluating imaging methods and prognostic factors to provide a clear basis for patient diagnosis and management.Objective: To investigate imaging methods and analyze the relevant prognostic factors for EAS.Methods: The retrospective study followed 64 cases of EAS diagnosed between 1992 and 2020. Clinical features, biochemical analysis, imaging studies were collected, and survival data was followed-up and analyzed.Results: Of 64 patients, 41% were female with a mean (±SD) age at diagnosis of 47±16 years. Computed tomography (CT), 18-F fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)-CT, and octreotide scintigraphy had similar sensitivity in localizing ectopic ACTH-secreting tumors. However, in cases with negative imaging on CT, both of 18F-FDG PET-CT and octreotide scintigraphy further localized 25% tumors. The combination of all three modalities failed to further increase the sensitivity. Patients with thymic tumors survived longer than those with pulmonary or pancreatic tumors (P=0.013 and 0.047, respectively). Multivariate analyses showed that hypokalemia (P=0.004) and treatment modality (P=0.048) were independent prognostic factors. The optimal serum potassium cut-off based on maximum log-rank statistics (P=0.012) was 2.90 mmol/L.Conclusion: CT is first-choice in tumor localization in EAS. CT in combination with a nuclear medicine or molecular imaging modality is necessary for further identification of an ectopic source. Serum potassium

  • Exposure to either bisphenol A or S represents a risk for crucial

    • Free pre-print version: Loading...

      Abstract: Maternal behavior depends on a multitude of factors, including the environmental ones, such as Endocrine Disrupting Chemicals (EDCs), which are increasingly attracting attention. Bisphenol A (BPA), an EDC present in plastic, is known to exert negative effects on maternal behavior. Bisphenol S (BPS), a BPA-substitute, seems to share some endocrine disrupting properties. In this study we focused on the analysis of the effects of low-dose (i.e., 4µg/kg body weight/day, EFSA TDI for BPA) BPA or BPS exposure throughout pregnancy and lactation in C57BL/6J mice. During the first postnatal week we observed the spontaneous maternal behavior. At the pups' weaning, we sacrificed the dams and analyzed the oxytocin system, involved in the control of the maternal care, in the hypothalamic magnocellular nuclei. At birth, pups from BPA-treated dams tended to have lower male-to-female ratio compared to controls, while the opposite was observed among BPS litters. During the first postnatal week, offspring mortality impacted differentially BPA and BPS litters, with more female dead pups among the BPA litters, while more male dead pups in the BPS litters, sharpening the difference in the sex ratio. BPA and BPS dams spent significantly less time in pup-related behaviors than controls. Oxytocin-ir in paraventricular and supraoptic nuclei was increased only in the BPA-treated dams. Alterations in maternal care, along with the treatment itself, may affect, later in life, the offspring physiology and behavior. The exposure to BPs during sensitive developmental periods represents a risk for both dams and offspring, even at low environmentally-relevant doses, through the functional alteration of neural circuits controlling fundamental behaviors for pup survival, such as maternal behaviors.

  • Delivery-dependent shift in oxytocin-responsive cell population in the
           central amygdala of the female rat

    • Free pre-print version: Loading...

      Abstract: Introduction: Despite its recent reputation as prosocial neurohormone, the most important physiological role of oxytocin (OT) is stimulating uterine contractions. Though it is well known that plasma OT concentrations change drastically during delivery, it remains unexplored whether and how OT receptors in the maternal brain are activated. We examined whether the responses of cells in the central amygdala (CeA), an OT receptor-rich limbic site involved in pain and fear memory regulation, to exogenously applied OT analogue, Thr-Gly-OT (TGOT), varies depending on delivery. Methods: Intracellular Ca2+ dynamics of the CeA cells were visualized in brain slices from female rats at virgin (VG), during pregnancy term days 16¬¬¬–21 (PT), within 24 hours after delivery (G0), and within one to three days after delivery (G3). The Ca2+ responses to 1 µM TGOT, 20 mM KCl (high K), and 300 µM ADP were compared. Results: We found that fraction of cells responding to TGOT, high K, and ADP differed significantly between the four delivery-associated terms. In particular, the fraction of cells responding to TGOT (TGOT responders) significantly increased from VG and PT at G0 and G3. Furthermore, the significant positive correlation between TGOT and high K response in TGOT-and-high K responders was reduced at G0, while that between TGOT and ADP responses in TGOT-and-ADP responders was increased at G0. Conclusion: These results indicate that the responses of CeA cells to an OT receptor agonist markedly change around delivery, which might play a role in controlling the labor-related pain and post-delivery emotional complications.

  • Progestogen-mediated neuroprotection in central nervous system disorders

    • Free pre-print version: Loading...

      Abstract: Neuroactive steroids can be synthetic or endogenous molecules produced by neuronal and glial cells, and peripheral glands. Examples include estrogens, testosterone, progesterone and its reduced metabolites such as 5-dihydroprogesterone and allopregnanolone. Steroids produced by neurons and glia target the nervous system and are called neurosteroids. Progesterone and analog molecules, known as progestogens, have been shown to exhibit neurotrophic, neuroprotective, antioxidant, anti-inflammatory, glial modulatory, promyelinating and remyelinating effects in several experimental models of neurodegenerative and injury conditions. Pleiotropic mechanisms of progestogens may act synergistically to prevent neuron degeneration, astrocyte and microglial reactivity, reducing morbidity and mortality. The aim of this review is to summarize the significant findings related to the actions of progesterone and other progestogens in experimental models and epidemiological and clinical trials of some of the most prevalent and debilitating chronic neurodegenerative disorders, namely Alzheimer’s disease, Parkinson’s disease, Huntington’s disease and Amyotrophic Lateral Sclerosis. We evaluated progestogen alterations presented under pathological conditions, how pathology modifies their levels, as well as the intracellular mechanisms and glial interactions underlying their neuroprotective effects. Furthermore, an analysis of the potential utility of natural progestogens and synthetic progestins as neuroprotective and regenerative agents, when administered exogenously as hormone replacement therapy in menopause, is also discussed.

  • Short and long term effects of chlorpyrifos on thyroid hormone axis and
           brain development in Xenopus laevis

    • Free pre-print version: Loading...

      Abstract: IntroductionThe extensive use of the insecticide chlorpyrifos (CPF) throughout the world has brought increased scrutiny on its environmental and health impact. CPF is a cholinergic neurotoxicant, however exposure to low noncholinergic doses is associated with numerous neurodevelopmental effects in animal models. In this study, we aimed to assess CPF for its potential to disrupt thyroid hormone signalling and investigate the short- and long-term effects on neurodevelopment by using Xenopus laevis. MethodsThe thyroid hormone (TH) disrupting potential of CPF was assessed using TH-sensitive transgenic Tg(thibz:eGFP) tadpoles. The consequences of early embryonic exposure were examined by exposing fertilized eggs for 72 hours to environmentally relevant CPF concentrations (10-10M and 10-8M). Three endpoints were evaluated: 1) gene expression in whole embryonic brains immediately after exposure, 2) mobility and brain morphology one week after exposure and 3) brain morphology and axon diameters at the end of metamorphosis (2 months after the exposure). ResultsCPF disrupted TH signaling in Tg(thibz:eGFP) tadpoles. The expression of genes klf9, cntn4, oatp1c1 and tubb2b was downregulated in response to CPF. Tadpoles exposed to CPF exhibited increased mobility and altered brain morphology compared to control tadpoles. Early embryonic exposure of CPF affected myelinated axon diameter, with exposed animals exhibiting shifted frequency distributions of myelinated axons diameters towards smaller diameters in the hindbrain of froglets.Discussion/Conclusion This study provides more evidence of the endocrine and neurodevelopment disrupting activity of CPF. Further experimental and epidemiological studies are warranted to determine the long-term consequences of early CPF exposure on brain development.

  • Prognosis of patients with bronchopulmonary neuroendocrine neoplasms in a
           tertiary NET Centre of Excellence

    • Free pre-print version: Loading...

      Abstract: Introduction: The European Neuroendocrine Tumor Society, ENETS, reports variables of prognostic significance in bronchopulmonary neuroendocrine neoplasms. The aim of this study was to investigate prognostic factors, recurrence free survival (RFS) and overall survival (OS) for patients with typical carcinoid (TC), atypical carcinoid (AC) and large cell neuroendocrine carcinoma (LCNEC). Current follow-up practices vary as the evidence is sparse and we aimed to explore the relevance of routine bronchoscopy in follow-up.Methods: A cohort study of 208 patients with bronchopulmonary neuroendocrine neoplasms (BP-NENs) followed at Aarhus University Hospital in 2008-2019. Kaplan-Meier method for RFS and OS were determined for the variables: primary tumor, primary treatment, smoking status, gender and histological subtypes.Results: The study included 153 patients with TC, 29 with AC and 26 with LCNEC. Median follow-up was 48 months.The majority of patients (n = 191) received surgical resection, of which 22 (11%) recurred over time. Seventeen patients had non-surgical treatment, of which 10 (59%) progressed. The 5-year OS-rate were 86% for operated and 9% for non-operated patients (p < 0.05). Patients with TC had a 5-year OS of 90% com-pared with 63% and 39% for AC and LCNEC, respectively. As for prognostic factors non-smokers did not secure a significant difference in OS compared with current/previous smokers (p = 0.51). In the follow-up period only two (9%) of the 22 recurrences were found on a routine bronchoscopy. Both of these recurrences were also found by diagnostic imaging. Conclusions: Surgical treatment, especially, and diagnosis of TC was associated with a good prognosis. Further, our data did not support routine bronchoscopy as part of a follow-up program for bronchial carcinoids.

      Abstract: Introduction: Angiotensin (Ang) II signalling in the hypothalamic paraventricular nucleus (PVN) via angiotensin type-1a receptors (AT1R) regulates vasopressin release and sympathetic nerve activity - two effectors of blood pressure regulation. We determined the cellular expression and function of AT1R in the PVN of a rodent model of polycystic kidney disease (PKD), the Lewis Polycystic Kidney (LPK) rat, to evaluate its contribution to blood pressure regulation and augmented vasopressin release in PKD. Methods: PVN AT1R gene expression was quantified with fluorescent in-situ hybridisation in LPK and control rats. PVN AT1R function was assessed with pharmacology under urethane anaesthesia in LPK and control rats instrumented to record arterial pressure and sympathetic nerve activity.Results: AT1R gene expression was upregulated in the PVN, particularly in CRH neurons, of LPK versus control rats. PVN microinjection of Ang II produced larger increases in systolic blood pressure in LPK versus control rats (36±5 vs. 17±2 mmHg; P

  • A novel signature based on m6A RNA methylation regulators reveals distinct
           prognostic subgroups and associates with tumor immunity of patients with
           pancreatic neuroendocrine neoplasms

    • Free pre-print version: Loading...

      Abstract: Introduction: The RNA N6-methyladenosine (m6A) regulators play a crucial role in tumorigenesis and could be indicators of prognosis and therapeutic targets in various cancers. However, the expression status and prognostic value of m6A regulators have not been studied in pancreatic neuroendocrine neoplasms (PanNENs). We aimed to investigate the expression patterns and prognostic value of m6A regulators and assess their correlations with immune checkpoints and infiltrates in PanNENs. Methods: Immunohistochemistry was performed for 15 m6A regulators and immune markers using tissue microarrays obtained from 183 patients with PanNENs. The correlation between m6A protein expression and clinicopathological parameters with recurrence-free survival (RFS) was examined using a random survival forest, Cox regression model and survival tree analysis. Results: Among the 15 m6A proteins, high expression of YTHDF2 and HNRNPC was found to be significantly associated with recurrence and served as independent risk factors. High YTHDF2 expression was associated with higher number of CD3+ T cells, whereas high HNRNPC expression was significantly correlated with the expression of PD-L1. A YTHDF2-based signature was determined, including five patterns from survival tree analysis: patients with the LNnegYTHDF2high signature had a 5-year RFS rate of 92.1%, whereas patients with LNposTumorSize<2.5cm signature had the worst 5-year RFS rate of 0%. The area under receiver operating characteristic curve was 0.870 for the YTHDF2-based signature. The C-index was 0.978, suggesting good discrimination ability; the risk score of recurrence served as an independent prognostic factor indicating shorter RFS. Conclusions: YTHDF2 appears to serve as a promising prognostic biomarker and therapeutic target. A YTHDF2-based signature can identify distinct subgroups, which may be helpful to strategize personalized postoperative monitoring.

  • Treatment response and clinical outcomes of well differentiated high grade
           neuroendocrine tumors to lutetium-177 DOTATATE

    • Free pre-print version: Loading...

      Abstract: Introduction: Lutetium-177 (177Lu)-DOTATATE received FDA approval in 2018 to treat somatostatin receptor (SSTR) positive gastroenteropancreatic neuroendocrine tumors (NETs). Little data are available on response and outcomes for well differentiated (WD) high grade (HG) NETs treated with 177Lu-DOTATATE. Materials and Methods: Patients with WD HG NETs treated with 177Lu-DOTATATE at MSK from 2018-2020 were identified. Demographics, response (RECIST 1.1), progression-free survival (PFS) were determined. Next-generation sequencing (NGS) was performed in archival tumor.Results: Nineteen patients, all with progressive, heavily-treated disease, were identified. Site of tumor origin: pancreas (74%), small bowel (11%), rectal (11%), lung (5%); median Ki-67 32% (range 22-56). Thirteen patients (68%) completed all four 177Lu-DOTATATE cycles. Best response (N=18 evaluable): 5/18 (28%) partial response, 8/18 (44%) stable disease, 5/18 (28%) disease progression. Median PFS 13.1 months (95% CI 8.7-20.9). Most common treatment-related toxicities: thrombocytopenia (9 patients, 47%; G3/4, 1 patient, 5%), anemia (7 patients, 37%; G3/4, 2 patients, 11%), leukopenia (6 patients, 32%; G3/4, 0 patients), liver function test elevation (4 patients, 21%; G3/4, 0 patients). NGS results were available from 13/19 tumors (68%). The most observed alterations were in MEN1 (6/13, 46%), DAXX (4/13, 31%). No RB1 alterations identified.Conclusion: We observed a meaningful disease control rate of 72% during treatment of WD HG NETs with 177Lu-DOTATATE. In this heavily pre-treated population, more than half of patients received all four treatment cycles with toxicities largely bone-marrow related. As would be expected in WD NETs, the vast majority had alterations in chromatin remodeling genes and no RB1 alterations.
