RNA Editome Imbalance in Hepatocellular Carcinoma

RNA editome imbalance in hepatocellular carcinoma.

Adenosine-to-inosine conversion (A-to-I editing), a posttranscriptional modification on RNA, contributes to extensive transcriptome diversity. A-to-I editing is a hydrolytic deamination process, catalyzed by adenosine deAminase acting on double-stranded RNA (ADAR) family of enzymes. ADARs are essential for normal mammalian development, and disturbance in RNA editing has been implicated in vario...

Hepatocellular Carcinoma in Sheep

Hepatocellular carcinoma in a sheep

At necropsy of a five-year-old sheep, a pear shaped, lobular yellow-brownish mass measuring about 12 ×15 × 20 cm was found to involve the right hepatic lobe. Microscopic examination revealed two trabecularand solid patterns of neoplastic hepatocytes. In solid pattern, there were numerous tumoral giant cells thatcontain one or more large hyperchromatic bizarre-shaped nuclei scattered among clust...

RNA Editome in Rhesus Macaque Shaped by Purifying Selection

Understanding of the RNA editing process has been broadened considerably by the next generation sequencing technology; however, several issues regarding this regulatory step remain unresolved--the strategies to accurately delineate the editome, the mechanism by which its profile is maintained, and its evolutionary and functional relevance. Here we report an accurate and quantitative profile of ...

Characterization of RNA editome in primary and metastatic lung adenocarcinomas

RNA editing results in post-transcriptional modification and could potentially contribute to carcinogenesis. However, RNA editing in advanced lung adenocarcinomas has not yet been studied. Based on whole genome and transcriptome sequencing data, we identified 1,071,296 RNA editing events from matched normal, primary and metastatic samples contributed by 24 lung adenocarcinoma patients, with 91....
