Dialogue between estrogen receptor and E2F signaling pathways: The transcriptional coregulator RIP140 at the crossroads

引用

Advances in Bioscience and Biotechnology 2013年第10期4卷 45-54页

作者： Marion Lapierre Aurélie Docquier audrey castet-nicolas Stéphan Jalaguier Catherine Teyssier Patrick Augereau Vincent Cavaillès IRCM—Institut de Recherche en Cancérologie de Montpellier Montpellier France

Estrogen receptors and E2F transcription factors are the key players of two nuclear signaling pathways which exert a major role in oncogenesis, particularly in the mammary gland. Different levels of dialogue between these two pathways have been deciphered and deregulation of the E2F pathway has been shown to impact the response of breast cancer cells to endocrine therapies. The present review focuses on the transcriptional coregulator RIP140/NRIP1 which is involved in several regulatory feed-back loops and inhibitory cross-talks between different nuclear signaling pathways. RIP140 regulates the transactivation potential of estrogen receptors and E2Fs and is also a direct transcriptional target of these transcription factors. Published data highlight the complex regulation of RIP140 expression at the transcriptional level and its potential role in transcription cross-talks. Indeed, a subtle regulation of RIP140 expression levels has important consequences on other transcription networks targeted by this coregulator. Another level of regulation implies titration mechanisms by which activation of a pathway leads to sequestration of the RIP140 protein and thus impinges other gene regulatory circuitries. Altogether, RIP140 occupies a place of choice in the dialogue between nuclear receptors and E2Fs, which could be highly relevant in various human pathologies such as cancer or metabolic diseases.

Background Atrial cardiomyopathy(AC)is an emerging concept explaining the pathophysiology of cardioembolic strokes in absence of atrial fibrillation(AF).A definition based on the presence of electrical abnormality(P-wave terminal force in lead V1(PTFV1)>5000µV×ms),N-Terminal pro-B-type natriuretic peptide(NT pro BNP)>250pg/mL and/or indexed left atrial diameter(LADI)>3cm/m^(2)is currently tested in the ARCADIA(AtRial Cardiopathy and Antithrombotic Drugs In prevention After cryptogenic stroke)*** set out to estimate the prevalence of AC as defined in the ARCADIA trial,its determinants and its association with AF detected after stroke(AFDAS).Methods Stepwise screening for silent Atrial Fibrillation After Stroke(SAFAS)study prospectively included 240 ischaemic stroke *** markers were complete for 192 of them and 9 were not included in this analysis because AF had been diagnosed on *** A total of 183 patients were analysed,of whom 57%(104 patients)met the AC criteria(79 NT-proBNP,47 PTFV1,4 LADI).In the multivariate logistic regression,C reactive protein>3mg/L(OR(95%CI)2.60(1.30 to 5.21),p=0.007)and age(OR(95%CI)1.07(1.04 to 1.10),p34mL/m^(2),OR 2.35(CI 1.09 to 5.06)p=0029).Conclusion AC as defined in ARCADIA is mostly based on NT pro BNP elevation(76%of patients)and is associated with age and ***,AC was not independently associated with AFDAS at *** ARCADIA trial,which compares aspirin to apixaban in patients with embolic strokes of undetermined source with AC markers and must,therefore be analysed in the light of these limitations.
