The tumor suppressor gene KCTD11REN is regulated by Sp1 and methylation and its expression is reduced in tumors

A hallmark of several human cancers is loss of heterozygosity (LOH) of chromosome 17p13. The same chromosomal region is also frequently hypermethylated in cancer. Although loss of 17p13 has been often associated with p53 genetic alteration or Hypermethylated in Cancer 1 (HIC1) gene hypermethylation, other tumor suppressor genes (TSGs) located in this region have critical roles in tumorigenesis. A novel TSG mapping on human chromosome 17p13.2 is KCTD11REN (KCTD11). We have recently demonstrated that KCTD11 expression is frequently lost in human medulloblastoma (MB), in part by LOH and in part by uncharacterized epigenetic events. Using a panel of human 177 tumor samples and their normal matching samples representing 18 different types of cancer, we show here that the down-regulation of KCTD11 protein level is a specific and a diffusely common event in tumorigenesis. Additionally, in order to characterize the regulatory regions in KCTD11 promoter, we identified a CpG island and several Sp1 binding sites on this promoter, and demonstrated that Sp1 transcription factor and DNA methylation contribute, at least in part, to regulate KCTD11 expression. Our findings identify KCTD11 as a widely down-regulated gene in human cancers, and provide a basis to understand how its expression might be deregulated in tumor cells

Accuracy of the clinical diagnosis of dementia with Lewy bodies (DLB) among the Italian Dementia Centers: a study by the Italian DLB study group (DLB-SINdem)

Introduction: Dementia with Lewy bodies (DLB) may represent a diagnostic challenge, since its clinical picture overlaps with other dementia. Two toolkits have been developed to aid the clinician to diagnose DLB: the Lewy Body Composite Risk Score (LBCRS) and the Assessment Toolkit for DLB (AT-DLB). We aim to evaluate the reliability of these two questionnaires, and their ability to enhance the interpretation of the international consensus diagnostic criteria. Methods: LBCRS and AT-DLB were distributed to 135 Italian Neurological Centers for Cognitive Decline and Dementia (CDCDs), with the indication to administer them to all patients with dementia referred within the subsequent 3 months. We asked to subsequently apply consensus criteria for DLB diagnosis, to validate the diagnostic accuracy of the two toolkits. Results: A total of 23 Centers joined the study; 1854 patients were enrolled. We found a prevalence of possible or probable DLB of 13% each (26% total), according to the consensus criteria. LBCRS toolkit showed good reliability, with a Cronbach alpha of 0.77, stable even after removing variables from the construct. AT-DLB toolkit Cronbach alpha was 0.52 and, after the subtraction of the "cognitive fluctuation" criterion, was only 0.31. Accuracy, sensitivity, and specificity were higher for LBCRS vs. AT-DLB. However, when simultaneously considered in the logistic models, AT-DLB showed a better performance (p\u2009<\u20090.001). Overall, the concordance between LBCRS positive and AT-DLB possible/probable was of 78.02% CONCLUSIONS: In a clinical setting, the LBCRS and AT-DLB questionnaires have good accuracy for DLB diagnosis

La traducción del teatro áureo en Italia, desde el siglo XIX hasta nuestros días. Constantes y variables en la formación de un canon

This essay aims to provide an over view of the Italian translations of Spanish Golden Age theatre from the 19th centur y to the present, identifying above all the differ-ences in the approach to Spanish texts compared to previous centuries and the distinc-tive features of each historical-cultural period within this long span of time. Romantic translations (a period marked by the great collections of theatrical texts by Monti and La Cecilia) were characterised by their marked preference for religious and honour-based dramas and for the works of Calderón; while the 20th centur y saw a general reworking of the corpus of translated texts, with a stable presence of Calderón and the recover y of the dramas on peasant honour by Lope de Vega. The emergence and affirmation of the poetic translation is highlighted, from the early experiments of the 1920s to the general acceptance of our days, and the role hispanists and writers played in this choice. An analysis of the corpus of translation collections in the 20th and 21st centuries, as well as of the many individual translations, also shows how the canon of the Spanish Golden Age theatre has changed both on the academic and editorial side
