Hypoxic regions are common in solid tumors and have an impact on tumor progression and on the therapeutic response. However, the underlying mechanism for hypoxic tumor microenvironment has not been entirely elucidated. Recently, long noncoding RNAs (lncRNAs) are being increasingly recognized to contribute to carcinogenesis through diverse mechanisms. To date, several lncRNAs have been described in...
Mantle cell lymphoma (MCL) is a rare lymphoma caused by the t(11:14) juxtaposing the cyclin D1 (CCND1) locus on chromosome 11 and the immunoglobulin heavy chain (IgH) locus on chromosome 14. Several new treatments are proposed for MCL, including histone deacetylase inhibitors (HDACi). We have studied gene expression and chromatin organization in the translocated 11q13 locus in MCL cells as compared...
Metastatic associated proteins (MTA) are integrators of upstream regulatory signals with the ability to act as master coregulators for modifying gene transcriptional activity. The MTA family includes three genes and multiple alternatively spliced variants. The MTA proteins neither have their own enzymatic activity nor have been shown to directly interact with DNA. However, MTA proteins interact with...
Gene systems are extremely complex, heterogeneous, and noisy in nature. Many statistical tools which are used to extract relevant feature from genes provide fuzzy and ambiguous information. High-dimensional gene expression database available in public domain usually contains thousands of genes. Efficient prediction method is demanding nowadays for accurate identification of such database. Euclidean...
TEAD proteins constitute a family of highly conserved transcription factors, characterized by a DNA-binding domain called the TEA domain and a protein-binding domain that permits association with transcriptional co-activators. TEAD proteins are unable to induce transcription on their own. They have to interact with transcriptional cofactors to do so. Once TEADs bind their co-activators, the different...
Genes related to human diseases should be natural targets for evolutionary studies, since they could provide clues regarding the genetic bases of pathologies and potential treatments. Here we studied the evolution of the reprimo gene family, a group of tumor-suppressor genes that are implicated in p53-mediated cell cycle arrest. These genes, especially the reprimo duplicate located on human chromosome...
microRNAs (miRNAs) are small noncoding RNAs that could regulate post-transcription level through binding to 3′ untranslated region (3′UTR) of target messenger RNAs (mRNAs), which were reported to be related with the incidence and development of diverse neoplasms. Among them, miR-197 was confirmed to play a vital role of oncogene or anti-oncogene in different cancers via targeting key tumorigenic or...
Ensuring continuous intracellular supply of thiamine is essential to maintain metabolism. Cellular homeostasis requires the function of the membrane bound thiamine transporters THTR1 and THTR2. In the absence of increased dietary intake of thiamine, varying intracellular levels to meet metabolic demands during pathophysiological stressors, such as hypoxia, requires adaptive regulatory mechanisms to...
