Abstract

Changes in microRNAs (miRNAs) expression in many types of cancer suggest that they may be involved in crucial steps during tumor progression. Indeed, miRNAs deregulation has been described in pituitary tumorigenesis, but few studies have described their role in pituitary tumor progression toward aggressiveness and malignancy. To assess the role of miRNAs within the hierarchical cascade of events in prolactin (PRL) tumors during progression, we used an integrative genomic approach to associate clinical-pathological features, global miRNA expression, and transcriptomic profiles of the same human tumors. We describe the specific down-regulation of one principal miRNA, miR-183, in the 8 aggressive (A, grade 2b) compared to the 18 non-aggressive (NA, grades 1a, 2a) PRL tumors. We demonstrate that it acts as an anti-proliferative gene by directly targeting KIAA0101, which is involved in cell cycle activation and inhibition of p53-p21-mediated cell cycle arrest. Moreover, we show that miR-183 and KIAA0101 expression significantly correlate with the main markers of pituitary tumors aggressiveness, Ki-67 and p53. These results confirm the activation of proliferation in aggressive and malignant PRL tumors compared to non-aggressive ones. Importantly, these data also demonstrate the ability of such an integrative genomic strategy, applied in the same human tumors, to identify the molecular mechanisms responsible for tumoral progression even from a small cohort of patients.

Abstract

JSRV (jaagsiekte sheep retrovirus) is a betaretrovirus, infecting small ruminants. This virus is responsible for the development of pulmonary adenocarcinoma, by the transformation of epithelial cells of the bronchioli and alveoli. This animal cancer is related to human bronchioloalveolar cancer (BAC), a specific form of human lung cancer for which a viral etiology has been proposed for several decades. In small ruminants JSRV interacts with the cells through the Hyal2 receptor. JSRV genome is simple and does not contain already known oncogene. It is now well established that the envelope protein is oncogenic by itself, via the cytoplasmic domain of the transmembrane glycoprotein and some domains of the surface glycoprotein. Activation of the PI3K/Akt and MAPK pathways participates to the envelope-induced transformation. The tumour development is associated with telomerase activation., Le jaagsiekte sheep retrovirus (JSRV) est un bêtarétrovirus, de la famille des rétrovirus, infectant les petits ruminants. Il induit un adénocarcinome pulmonaire, un cancer du poumon se développant par transformation des cellules épithéliales du poumon profond que sont les pneumocytes de type II et les cellules de Clara. Cette tumeur est apparentée au cancer bronchioloalvéolaire, une forme particulière de cancer du poumon chez l’homme, pour laquelle une étiologie virale a été suggérée depuis de nombreuses années. Le JSRV interagit avec la cellule par sa fixation sur le récepteur Hyal2. Son génome est simple et ne contient pas d’oncogène connu. Il est maintenant clairement établi qu’il induit la transformation cellulaire, in vitro et in vivo, via son enveloppe. Son pouvoir transformant implique le domaine intracytoplasmique de la transmembrane et certains domaines de la glycoprotéine de surface. La transformation met en jeu l’activation des voies PI3K/Akt et MAPK ; le développement de la tumeur est associé à l’activation de la télomérase.

25. Evidence of a change in effectiveness of the efferent olivocochlear system in the presence of phantom auditory perception (tinnitus)

Author

Chéry-Croze S, Giraud A, and Duchamp C

Abstract

The intervention of the medial efferent olivocochlear system in phantom auditory perception (tinnitus) mechanisms has been proposed by several authors. This study aimed to search for a change in the functioning of this system in three normal-hearing groups distinguished by the presence or absence of spontaneous otoacoustic emissions and tinnitus. The medial olivocochlear system's effect was measured by comparing transient evoked otoacoustic emission amplitudes in one ear with and without contralateral acoustic stimulation. Ipsilateral and contralateral stimulation levels were varied. Results showed that the slope of the growth of the medial olivococlear effect with contralateral sound level was reduced in the presence of tinnitus, revealing a functional correlate of this phantom perception. Several possibilities for interpreting this result are discussed. [ABSTRACT FROM AUTHOR]

26. Validation assessment of a French version of the Tinnitus Reaction Questionnaire: a comparison between data from English and French versions.

Author

Meric C, Pham E, and Chery-Croze S

Abstract

The present study compares the results obtained on original and French versions of the TRQ (Tinnitus Reaction Questionnaire) initially published by Wilson, Henry, Bowen, and Haralambous (1991) in English to evaluate the psychological distress of tinnitus sufferers. Reliability and validity of the French translation were determined using data from 173 normal hearing or hearing-impaired patients with tinnitus lasting from 1 month to 41 years. They completed the translated questionnaire and a short version of the Minnesota Multiphasic Personality Inventory. The results indicated good internal consistency (Cronbach's alpha = .94), and the reliability of the French version of the TRQ was demonstrated, except for items 5 and 20. High statistically significant correlations were found between the TRQ and Depression, Psychaesthenia, and Anxiety Mini-Mult subscales. The validation demonstrates only minor effects of language. The French version of the TRQ thus is an equally valid tool as the original English version for evaluating tinnitus distress of a patient. [ABSTRACT FROM AUTHOR]

33. The thermal sensitivity of the polymodal nociceptors in the monkey.

Author

Croze, S, Duclaux, R, and Kenshalo, D R

Abstract

1. The static and dynamic sensitivities to thermal and mechanical stimuli of polymodal nociceptors in hairy skin of the anaesthetized monkey have been investigated by recording activity in their primary nerve fibres. 2. Polymodal nociceptors responded to skin pricking, pinching and heating to temperatures higher than 40 degrees C. They did not respond to touch, stretch or cold. The conduction velocity of their axons was from 0.6 to 1.1 m/sec. 3. Three types of cutaneous receptive fields have been observed: single spot‐like areas of 1‐2 mm2; multiple spot‐like areas of 1‐2 mm2; and larger areas up to 25 mm2 with heterogeneous sensitivity. 4. Polymodal nociceptors were subjected to heat stimuli that commenced from a 33 or 37 degrees C adapting temperature. A series consisted of heating their receptive fields to 43, 45, 47 and 50 degrees C from one or the other adapting temperatures at a constant rate of 0.2 degrees C/sec. Each heat stimulus intensity was maintained for 4 min after which the skin was returned to the adapting temperature. Immediately after the first series the identical series was repeated in order to determine the effect of prior heating upon the dynamic responses to re‐heating. The dynamic responses were characterized by three phases: an initiation of a discharge at a threshold level of skin temperature; a dynamic discharge during the suprathreshold change, that reached a peak frequency when the temperature reached its maximum; and an adaptation phase while the temperature remained at the high intensity. Adaptation was rapid initially, and then slowed during the final minutes at the high intensity. 5. Adapting the receptive field to either 33 degrees C or to 37 degrees C before the heat stimuli did not affect the sensitivity and the discharge pattern of the polymodal nocicpetors. 6. During the first series of stimulations, the threshold at which the individual polymodal nociceptors began to discharge to heat stimuli varied from 40 to 46.5 degrees C. The mean threshold of the population was 42.5 degrees C. 7. No change in the threshold was observed when responses to 0.2 and 1.5 degrees C/sec rates of heating were compared...

34. Immunocytochemical study of peptidergic structures in Brunner's glands

Author

Bosshard, A., Chery-Croze, S., Cuber, J.C., Dechelette, M.A., Berger, F., and Chayvialle, J.A.

Abstract

Nervous and endocrine peptidergic structures in human Brunner's glands were studied by immunofluorescence. Endocrine cells storing immunoreactive components respectively similar to somatostatin 14, the amino-terminal portion (1–14) of somatostatin 28, gastrin-cholecystokinin, and peptide YY were distributed throughout the acini. Peptidergic nerve structures contained materials immunologically related to vasoactive intestinal peptide, peptide histidine methionine, substance P, neuropeptide Y, and gastrin-releasing peptide. The latter peptide was detected in discrete fibers running into the acini but within no cell body in the submucosa. All other neuropeptides were stored in fibers, isolated or grouped in bundles, and in perikarya of submucosal ganglia close to the acini. No immunoreactive structures were detected using antisera directed against pancreatic polypeptide, secretin, motilin, neurotensin, or calcitonin gene-related peptide. The results suggest that several regulatory peptides may be involved in the control of Brunner's glands in humans.
