Adipogenesis is regulated by the sequential activation of a series of transcription factors: the C/EBP proteins of type beta and delta trigger the process while PPARgamma and C/EBPalpha induce the differentiation from pre-adipocyte to adipocyte, followed by adipo-specific gene expression. A number of observations suggest the involvement of genes controlling(More)
Liver organogenesis and cancerogenesis share common mechanisms. HOX genes control normal development, primary cellular processes and are characterized by a unique genomic network organization. Less is known about the involvement of HOX genes with liver cancerogenesis. The comparison of the HOX gene network expression between nontumorous livers and(More)
The HOX network contains 39 genes that act as transcriptional regulators and control crucial cellular functions during both embryonic development and adult life. Inside the network, this is achieved according to the rules of temporal and spatial co-linearity with 3' HOX genes acting on the anterior part of the body, central HOX genes on the thoracic part(More)
Molecular etiology of thyroid cancers has been widely studied, and several molecular alterations have been identified mainly associated with follicular and papillary histotypes. However, the molecular bases of the complex pathogenesis of thyroid carcinomas remain poorly understood. HOX genes regulate normal embryonic development, cell differentiation and(More)
Genito-urinary malignancies (prostate, bladder, renal and testicular cancers) rank high among human tumors with an incidence that varies with age and organ involvement. Prostate cancer is the most commonly detected male cancer followed by bladder and kidney cancers, less frequent in women. Testicular cancer, although rare, is the most frequent cancer in(More)
Homeobox genes are transcription factors primarily involved in embryonic development. Several homeobox gene families have so far been identified: Hox, EMX, PAX, MSX as well as many isolated divergent homeobox genes. Among these, Hox genes are most intriguing for having a regulatory network structure organization. Recent indications suggest the involvement(More)
Bladder carcinogenesis remains unclear despite the identification of chemical, environmental and genetic factors. It has recently been reported that the chromosomal region 12q13-q15, containing crucial cancer genes such as MDM2, CDK4 and GLI, is amplified in bladder cancer. In the same region are also located the genes of the locus HOX C, flanked by keratin(More)
Homeobox-containing genes comprise a gene family coding for transcription factors involved in normal development. Class I human homeobox (HOX) genes display a peculiar chromosomal organization, perhaps directly related to their function. Aberrant expression of homeobox genes has been associated with both morphological abnormalities and oncogenesis. We have(More)
Homeobox-containing genes are a family of regulatory genes encoding transcription factors that primarily play a crucial role during development. Several indications suggest their involvement in the control of cell growth and, when dysregulated, in oncogenesis. We will describe the implications, in tumor origin and evolution, of members of the homeobox gene(More)
OBJECTIVES To discuss the current knowledge on induction, production, sustenance and promotion of neuroendocrine differentiation in human prostate cancer. METHODS Review of the literature using PubMed search and scientific journal publications. RESULTS Morphological evidence explains some functional relationship between neuroendocrine and neoplastic(More)
