Many biomarkers for breast cancer prognosis have been proposed during the last two decades, among which HER2 and oestrogen receptors are of common use in routine clinical practice. However, in recent years, BCL2 has been recognized as an important prognostic parameter in human breast cancer, although its clinical utility is well established. The aim of this(More)
Primary mucinous thyroid carcinoma (PMTC) are extremely rare lesions that are histologically indistinguishable from mucinous carcinoma of other sites. We describe the clinicopathological, histological and immunohistochemical features of this rare tumour with a review of the literature. We describe a case of thyroid tumour, in 56-year-old Tunisian man,(More)
The ubiquitin-proteasome system plays an essential regulatory role in various cellular processes. Besides its involvement in normal cellular functions, the alteration of proteasomal activity contributes to the pathological states of several clinical disorders, including cancer. Aberrant methylation of the CpG islands has been reported as an alternative way(More)
Aberrant expression of miR-10b has been described in many cancers but remains unexplored in nasopharyngeal carcinoma (NPC). Therefore, we aimed to study the miR-10b expression level in 43 NPC biopsies collected from Tunisian patients and three NPC xenografts. Then, we investigated the correlation between miR-10b expression and its upstream regulators(More)
MicroRNAs are emergent players of epigenetics that function as oncogenes or tumor suppressors and that have been implicated in regulating diverse cellular pathways. MiR-10b is an oncogenic microRNA involved in tumor invasion and metastasis in various cancers. Our data have shown that miR-10b is overexpressed in colorectal cancer samples in comparison with(More)
INTRODUCTION Myofibroblastoma of the breast (MFB) is an unusual benign tumour that belongs to the family of benign spindle cell tumours of the mammary stroma. The detection of smooth muscle cells in MFB is explained by its histogenesis from CD34+ fibroblasts of mammary stroma capable of multidirectional mesenchymal differentiation, including smooth muscle.(More)
Aberrant DNA methylation of CpG islands occurred frequently in CRC and associated with transcriptional silencing of key genes. In this study, the CIMP combined with MLH1 or p16 INK4a methylation status was determined in CRC patients and correlated with clinicopathological parameters and overall survival. Our data showed that CIMP+ CRCs were identified in(More)
