    ABSTRACT: To evaluate the construct and criterion validity of the Tuebingen Cushing's disease Quality of Life Inventory (Tuebingen CD-25) for the application in patients treated for Cushing's disease (CD). A total of 176 patients with ACTH-dependent CD (144 of them female, overall mean age 46.1 ± 13.7 years) treated at 3 large tertiary referral centers in Germany were studied. Construct validity was assessed by hypothesis testing (self-perceived symptom reduction assessment) and contrasted groups (patients with vs. without hypercorticolism). For this purpose, already existing data from 55 CD patients were used representing the hypercortisolaemic group. Criterion validity (concurrent validity) was assessed in relation to the Cushing's Quality of Life questionnaire (CushingQoL), Short-Form-36 health survey (SF-36) and the Body Mass Index (BMI). Patients with self-perceived remarkable symptom reduction had significant lower Tuebingen CD-25 scores (i.e. better HRQoL) than patients with self-perceived insufficient symptom reduction (p < 0.05). Similar, the mean scores of the Tuebingen CD-25 scales were lower in patients without hypercortisolism (Total Score 27.0 ± 17.2) compared to those with hypercortisolism (Total Score 45.3 ± 22.1) (each p < 0.05), providing evidence for construct validity. Criterion validity was confirmed by the correlations between the Tuebingen CD-25 Total Score and the CushingQoL (Spearman's coefficient -0.733) as well as all scales of the SF-36 (Spearman's coefficient between -0.447 and -0.700). The analyses presented in this large sample provide robust evidence for the construct and criterion validity of the Tuebingen CD-25. © 2015 S. Karger AG, Basel.

    ABSTRACT: Chromogranin A (CgA) has been considered to be valuable not only in the diagnosis but also in monitoring the disease response to treatment. However, only a few studies have been published on this issue. We purposed to evaluate whether biochemical response using plasma CgA level is reliable in concordance with the clinical response of grade 1-3 nonfunctiong gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Between March 2011 and September 2013, a total of 27 cases in 18 patients were analysed, clinically and radiologically while serial CgA tests were also conducted during treatment. Tumor responses were defined by both RECIST criteria 1.1 and biochemical criteria based on the CgA level. Among the 27 cases analysed, no difference in the basal CgA level was observed with regard to gender, primary tumor site, tumor grade (WHO classification), liver metastasis, number of metastatic site, and line of chemotherapy. The overall response rate (RR) by RECIST criteria 1.1 was 6 out of the 27 cases (22.2%) and 8 out of the 27 cases (29.6%) for biochemical RR. The overall concordance rates of the response based on RECIST and biochemical criteria were 74%. In grades 1 and 2 GEP-NETs (n=17), the concordance rate of the disease control was 94.1%. There was a significant difference for progression free survival (PFS) between responders and non-responder in accordance to biochemical criteria (35.73 months vs. 5.93 months, p=0.05). s This study revealed that changes of the plasma CgA levels were associated with tumour response. Additionally, biochemical response based on serial CgA may be a predictive marker for PFS in GEP-NETs.

    ABSTRACT: Merkel cell carcinoma (MCC) is a rare neuroendocrine carcinoma with poorly understood molecular etiology. We implemented a comprehensive deep sequencing approach to identify mutations in the tumor DNA from a cohort of patients treated at our institution over the past 15 years. Our results indicate mutations that may constitute therapeutic targets in MCC. Methods: Five patients were treated for MCC within the study interval. Patients with adequate tissue (n = 4), positive neuroendocrine differentiation (Chromogranin, Synaptophysin, and CK20), and histopathological confirmation of MCC were included in the study. DNA was extracted from archival tumor tissue samples and analyzed by massively parallel sequencing using a targeted, multiplex PCR approach followed by semiconductor sequencing. Results: We demonstrate high penetrance nonsense mutations in PDE4DIP (n = 4) as well as various missense mutations in the DNA Damage Response (PRKDC, AURKB, ERCC5, ATR, and ATRX) and epigenetic modulating enzymes (MLL3). Conclusion: We describe several mutations in potential disease-relevant genes and pathways. These targets should be evaluated in a larger cohort to determine their role in the molecular pathogenesis of MCC. © 2015 S. Karger AG, Basel.

    ABSTRACT: Continuous activation of the kisspeptin receptor by its agonists causes abrogation of kisspeptin signaling, leading to decreased pulsatile luteinizing hormone (LH) secretion. Employing this phenomenon as a tool for probing kisspeptin action, this study aimed to clarify the role of kisspeptin in gonadotropin-releasing hormone (GnRH) pulse generation in goats. We examined the effects of chronic administration of TAK-683, an investigational kisspeptin analog, on LH secretion, GnRH immunostaining, pituitary responses to exogenous GnRH, and GnRH pulse generator activity, reflected by a characteristic increase in multiple-unit activity (MUA volley). An osmotic pump containing TAK-683 was subcutaneously implanted on Day 0. TAK-683 treatment dose-dependently suppressed pulsatile LH secretion on Day 1. Higher doses of chronic TAK-683 profoundly suppressed pulsatile LH secretion but had little effect on GnRH immunostaining patterns and pituitary responses to GnRH on Day 5. In ovariectomized goats, MUA volleys occurred at approximately every 30 min on Day -1. On Day 5 of chronic TAK-683 administration, pulsatile LH secretion was markedly suppressed, whereas MUA volleys were similar to those observed on Day -1. Male pheromones and senktide (neurokinin B receptor agonist) induced an MUA volley but had no effect on LH secretion during chronic TAK-683 administration. The results indicate that chronic administration of a kisspeptin analog profoundly suppresses pulsatile LH secretion without affecting GnRH content, pituitary function, or GnRH pulse generator activity, and suggest an indispensable role for kisspeptin signaling in the cascade driving GnRH/LH pulses by the GnRH pulse generator. © 2015 S.

    ABSTRACT: The hypothalamic-pituitary system is essential to maintain life and control systemic homeostasis, but it is negatively affected by various diseases, leading to serious symptoms. Embryonic stem (ES) cells differentiate into neuroectodermal progenitors when cultured as floating aggregates under serum-free conditions. Recently, our colleagues showed that strict removal of exogenous patterning factors during early differentiation steps induced efficient generation of rostral hypothalamic-like progenitors from mouse ES cell-derived neuroectodermal cells. The use of growth factor-free chemically defined medium was critical for this induction. The ES cell-derived hypothalamic-like progenitors generated rostral-dorsal hypothalamic neurons, especially magnocellular vasopressinergic neurons that release the hormone upon stimulation. Subsequently, we reported efficient self-formation of three-dimensional adenohypophysis tissues in aggregate cultures of mouse ES cells. The ES cells were stimulated to differentiate into non-neural head ectoderm and hypothalamic neuroectoderm in adjacent layers within the aggregate, and then treated with Hedgehog. Self-organization of Rathke's pouch-like structures occurred at the interface of the two epithelia, as observed in vivo, and various endocrine cells including corticotrophs and somatotrophs were subsequently produced. The corticotrophs efficiently secreted adrenocorticotropic hormone in response to corticotropin-releasing hormone. Furthermore, when engrafted in vivo, these cells rescued the systemic glucocorticoid level in hypopituitary mice. Our present research aims are to prepare hypothalamic and pituitary tissues from human-induced pluripotent stem cells and establish effective transplantation techniques with clinical applications. To replicate the complex and precise control of the hypothalamic-pituitary system, regenerative medicine using pluripotent cells may be a hopeful option. © 2015 S. Karger AG, Basel.

    ABSTRACT: Hyperactivity of the hypothalamic-pituitary-adrenal axis is a consistent biological characteristic of depression and response normalization coincides with clinical responsiveness to antidepressant medications. Desensitization of serotonin 1A receptor (5-HT1AR) signaling in the hypothalamic paraventricular nucleus (PVN) follows selective serotonin reuptake inhibitor (SSRI) antidepressant treatment and contributes to the antidepressant response. Estradiol alone produces a partial desensitization of 5-HT1AR signaling, and synergizes with SSRIs to result in a complete and more rapid desensitization than with SSRIs alone as measured by a decrease in the oxytocin and adrenocorticotrophic hormone(ACTH) responses to 5-HT1AR stimulation. G protein-coupled estrogen receptor1 (GPER1) is necessary for estradiol-induced desensitization of 5-HT1AR signaling, although the underlying mechanisms are still unclear. We now find that stimulation of GPER1 with the selective agonist G-1 and non-selective stimulation of estrogen receptors dramatically alter isoform expression of a key component of the 5-HT1AR signaling pathway, RGSz1, a GTPase activating protein selective for Gαz, the Gα subunit necessary for 5-HT1AR-mediated hormone release. RGSz1 isoforms are differentially glycosylated, SUMOylated, and phosphorylated, and differentially distributed in subcellular organelles. High molecular weight RGSz1 is SUMOylated and glycosylated, localized to the detergent-resistant microdomain (DRM) of the cell membrane, and increased by estradiol and G-1 treatment. Because activated Gαz also localizes to the DRM, increased DRM-localized RGSz1 by estradiol and G-1could reduce Gαz activity, functionally uncoupling 5-HT1AR signaling. Peripheral G-1 treatment produced partial reduction in oxytocin and ACTH responses to 5-HT1AR-stimulation similar to direct injections into the PVN. Together, these results identify GPER1 and RGSz1 as novel targets for the treatment of depression. © 2014 S. Karger AG, Basel.

    ABSTRACT: Objective: The onset of menstruation is the hallmark of female pubertal development. The present study determined whether pubertal girls experience adrenocortical and ovarian steroid secretions within their first waking hour before getting their period, similar to those observed in adult females with regular cycles. Methods: Cortisol, dehydroepiandrosterone (DHEA), and estradiol-17β concentrations were measured in saliva samples collected after awakening (0, 30, and 60 min after awakening) from 158 normal premenarcheal pubertal girls and 69 adult females with regular menstrual cycles. The girls were subgrouped according to self-reported Tanner breast (B) and pubic hair (PH) stages (B1PH1, B2PH1, B2PH2, B3PH1, and B3PH2). Results: All the subgroups showed a similar pattern of cortisol secretion. However, cortisol levels were higher in girls at B3PH1 and at B3PH2 than other subgroups. DHEA secretion showed a similar pattern across the groups examined. The largest increase in DHEA levels occurred between B1PH1 and B2PH1 stages, and further increased with pubertal progression. DHEA levels in girls at B3PH2 were approximately one-half of the adult value. Estraiol-17β profiles in girls at B3PH1 and B3PH2 differed from those of other subgroups of girl. A sharp increase in estraiol-17β levels after awakening which observed in adult females emerged in girls at B3PH1 and B3PH2. However, the estradiol-17β levels did not reach adult values until B3PH2 stage. Conclusions: The progression of female puberty includes an increase in the levels of adrenocortical and ovarian steroid secretions and a gain of adult female-like patterns of estradiol-17β secretion within their first waking hour. © 2014 S.

    ABSTRACT: Background: Female Cushing's disease (CD) patients with active disease present more frequently with depression compared to their male co-sufferers. This study investigated whether the gender difference prevails after remission and whether gender-specific factors contributing to mental health exist. Methods: Seventy-two biochemically cured CD patients (11 male, mean age 45.9 ± 13.7 years) who underwent transsphenoidal tumour removal filled out the Symptom Checklist-90-Revised inventory on average 42.1 ± 32.9 months after surgery. Regression analyses included the following independent factors: (i) age, (ii) presence of comorbidities, (iii) presence of hypocortisolism, (iv) presence of hypopituitarism, (v) disease duration until diagnosis, (vi) time elapsed since surgery and (vii) postoperative radiotherapy to predict postoperative psychopathology. Results: Regarding the Global Severity Index, 23.0% of the female and 27.3% of the male CD patients presented with abnormal scores. In all nine dimensions, psychopathological abnormalities were present in both female and male patients with the same frequency and intensity (each p > 0.05). Prolonged time to diagnosis was a strong predictive factor for worse psychopathological status only in male patients. Among female patients, merely the presence of comorbidities and to some extent pituitary deficiencies were related to psychopathological status. Conclusions: During the remissional phase of CD, female and male patients present with similar psychopathological profiles. In males, long-term biochemical effects of previous hypercortisolism seem to be salient for psychopathology. In contrast, in females, the presence of comorbidities/stressors they have to cope with is the predictive factor for psychopathology. The results underline gender differences in Cushing's disease and the need to separate them on various issues. © 2014 S. Karger AG, Basel.
