Ras association (RalGDS/AF-6) domain family member 2 (RASSF2) is a gene involved in the progression of several human cancers, including breast, colorectal and lung cancer. The aims of this study were to determine the hypermethylation of the gene in squamous cervical cancer and precursor lesions, along with that of RASSF1 and the recently described EPB41L3,(More)
Breast cancer is a heterogeneous disease that can be subdivided into clinical, histopathological and molecular subtypes (luminal A-like, luminal B-like/HER2-negative, luminal B-like/HER2-positive, HER2-positive, and triple-negative). The study of new molecular factors is essential to obtain further insights into the mechanisms involved in the tumorigenesis(More)
Methylation of DNA at carbon 5 of cytosine is essential for mammalian development and implicated in transcriptional repression of genes and transposons. New patterns of DNA methylation characteristic of lineage-committed cells are established at the exit from pluripotency by de novo DNA methyltransferases enzymes, DNMT3A and DNMT3B, which are regulated by(More)
Pleomorphic ductal carcinoma of the breast is a rare variant included in the morphological group of infiltrating ductal carcinoma. The pleomorphic carcinoma is composed predominantly of epithelial and multinucleated tumor giant cells. We report here two cases presenting a lesion composed microscopically of a proliferation of large pleomorphic cells with a(More)
