EINCR1 is an EGF inducible lincRNA overexpressed in lung adenocarcinomas
Long non-coding RNAs are being increasingly recognised as important molecules involved in regulating a diverse array of biological functions. For example, many long non-coding RNAs have been associated with tumourigenesis and in this context their molecular functions often involves impacting on chromatin and transcriptional control processes. One important cellular control system that is often ...
متن کاملRb and p53 Liver Functions Are Essential for Xenobiotic Metabolism and Tumor Suppression
The tumor suppressors Retinoblastoma (Rb) and p53 are frequently inactivated in liver diseases, such as hepatocellular carcinomas (HCC) or infections with Hepatitis B or C viruses. Here, we discovered a novel role for Rb and p53 in xenobiotic metabolism, which represent a key function of the liver for metabolizing therapeutic drugs or toxins. We demonstrate that Rb and p53 cooperate to metaboli...
متن کاملSuppression of TET1-dependent DNA demethylation is essential for KRAS-mediated transformation.
Hypermethylation-mediated tumor suppressor gene (TSG) silencing is a central epigenetic alteration in RAS-dependent tumorigenesis. Ten-eleven translocation (TET) enzymes can depress DNA methylation by hydroxylation of 5-methylcytosine (5mC) bases to 5-hydroxymethylcytosine (5hmC). Here, we report that suppression of TET1 is required for KRAS-induced DNA hypermethylation and cellular transformat...
متن کاملSuppression of PTEN expression is essential for antiapoptosis and cellular transformation by oncogenic Ras.
Ras is one of the most commonly mutated oncogenes in the array of human cancers. The mechanism by which Ras induces cellular transformation is, however, not fully elucidated. We present here evidence that oncogenic Ras suppresses the expression of the tumor suppressor phosphatase and tensin homologue deleted from chromosome 10 (PTEN), and this action of oncogenic Ras is mediated by the Raf-mito...
متن کاملPontin functions as an essential coactivator for Oct4-dependent lincRNA expression in mouse embryonic stem cells
The actions of transcription factors, chromatin modifiers and noncoding RNAs are crucial for the programming of cell states. Although the importance of various epigenetic machineries for controlling pluripotency of embryonic stem (ES) cells has been previously studied, how chromatin modifiers cooperate with specific transcription factors still remains largely elusive. Here, we find that Pontin ...
