Potentially there are more ncRNA molecules yet to be found and their possible functions are to be revealed. The discovery of ncRNAs is a difficult task because they lack sequence indicators such as the start and stop codons dis- played by protein-coding RNAs. Current methods utilize either sequence motifs or structural parameters to detect novel ncRNAs within genomes. Here, we present an ab initio ncRNA finder, named ncRNAscout, by utilizing both sequence motifs and structural parameters. Specifically, our method has three components： （i） a measure of the frequency of a sequence, （ii） a measure of the structural stability of a sequence contained in a t-score, and （iii） a measure of the frequency of certain patterns within a sequence that may indicate the presence of ncRNA. Experimental results show that, given a genome and a set of known ncRNAs, our method is able to accurately identify and locate a significant number of ncRNA sequences in the genome.

The mutational inactivation of both gene alleles brings on this cancer. Retinoblastoma (RB) high-risk histopathological characteristics indicate metastasis or local recurrence with rapid progresses following RB1 inactivation. There is growing interest in regulatory activities unconnected to the coding region of the genome, or exome, in addition to epigenetic control mechanisms. The altered epigenome is significant, though by no means the only, problem in the etiology of Retinoblastoma. After all, cancer development is a multistep process in which numerous dissimilar genetic, epigenetic, and posttranscriptional modifications result in a shared phenotype. This study emphasizes the most recent developments in posttranscriptional change and epigenetics related to retinoblastoma tumor biology. Here, we highlight the novel biomarkers the retinoblastoma tumor has expressed to improve patient survival.展开更多
