MIRNA NEL CARCINOMA EPATOCELLULARE
Variazioni di miRNA circolanti in casi di carcinoma mammario sottoposti a regime dietetico con oli addizionati di polifenoli
Dal 2002, quando i primi risultati relativi alla possibile associazione tra espressione di alcuni miRNA e cancro furono pubblicati, numerosi studi hanno evidenziato un intervento diretto dei miRNA nella regolazione di geni e di pathways collegati alla sviluppo tumorale. Recentemente si sta sempre più confermando l’evidenza che cambiamenti epigenetici, alterazioni molecolari e componenti bioattivi della dieta possono genericamente modificare l'espressione genica attraverso la modulazione di specifici miRNA. Scopo principale della ricerca è la valutazione dei livelli di espressione di particolari miRNA circolanti nel sangue periferico sia di donne sane che di pazienti affette da carcinoma mam…
miRNAs in the metaplastic transformation of the esophagus: something in the way toward carcinogenesis.
Background: Barrett's esophagus (BE) is a precancerous lesion that predisposes to development of esophageal adenocarcinoma (EAC) and it is associated with gastroesophageal reflux disease. Genetic changes involved in the metaplastic progression from squamous esophageal mucosa toward Barrett’s metaplasia and adenocarcinoma are almost unknown and there is an increasing interest in the developing of more objective biomarkers that can improve risk prediction. Several evidences suggest that some miRNAs are differentially expressed in the BE and EAC. Among them, miR-143, miR-145, miR-194, miR-203, miR-205, miR-215 appear to have a key role in the metaplasia and in neoplastic progression. Aim: The …
El uso de microesferas de vidrio marcadas con Itrio-90 en el tratamiento del hepatocarcinoma
2021
OBJETIVO: Establecer el valor pronóstico de las variables incluidas en el estudio (clínicas, dosimétricas, analíticas y demográficas) en la progresión de enfermedad y la supervivencia global de aquellos pacientes afectos de hepatocarcinoma en estadio intermedio y avanzado del BCLC y tratados con radioembolización con microesferas cargadas con Y90, así como los efectos secundarios derivados del tratamiento. MATERIAL Y MÉTODO: Estudio retrospectivo, analítico y observacional realizado en el Hospital Universitario y Politécnico la Fe (Valencia) que incluye a 53 pacientes tratados con radioembolización desde marzo de 2009 hasta diciembre de 2016. Todos ellos fueron clasificados según el algorit…

A SUMOylation-defective MITF germline mutation predisposes to melanoma and renal carcinoma
2011
International audience; So far, no common environmental and/or phenotypic factor has been associated with melanoma and renal cell carcinoma (RCC). The known risk factors for melanoma include sun exposure, pigmentation and nevus phenotypes; risk factors associated with RCC include smoking, obesity and hypertension. A recent study of coexisting melanoma and RCC in the same patients supports a genetic predisposition underlying the association between these two cancers. The microphthalmia-associated transcription factor (MITF) has been proposed to act as a melanoma oncogene; it also stimulates the transcription of hypoxia inducible factor (HIF1A), the pathway of which is targeted by kidney canc…

A STAT4 variant increases liver fibrosis risk in Caucasian patients with chronic hepatitis B
2018
Background Host genetic modifiers of the natural history of chronic hepatitis B (CHB) remain poorly understood. Recently, a genome-wide association study (GWAS)-identified polymorphism in the STAT4 gene that contributes to the risk for hepatocellular carcinoma (HCC) was shown to be associated with the full spectrum of hepatitis B virus (HBV) outcomes in Asian patients. However, the functional mechanisms for this effect are unknown and the role of the variant in modulating HBV disease in Caucasians has not been investigated. Aims To determine whether STAT4 genetic variation is associated with liver injury in Caucasian patients with CHB and to investigate potential mechanisms mediating this e…
Expression of 60-kD Heat Shock Protein Increases during Carcinogenesis in the Uterine Exocervix
2002
<i>Objectives:</i> The aim of the present study was to determine the presence and expression of the 60-kD heat shock protein (HSP60) in the dysplasia-carcinoma sequence in the uterine exocervix and to evaluate its diagnostic and prognostic significance. <i>Methods and Results:</i> We performed Western blot and immunohistochemical analyses on biopsies from 40 cases, consisting of 10 normal exocervical biopsies, 10 low-grade squamous intraepithelial lesions (L-SIL), 10 high-grade squamous intraepithelial lesions (H-SIL) and 10 cancerous exocervices (G2 grade). The immunohistochemical results were quantified by computer-assisted image analysis. Western blot analysis sho…
