Pseudogenes regulate parental gene expression via ceRNA network
The concept of competitive endogenous RNA (ceRNA) was first proposed by Salmena and colleagues. Evidence suggests that pseudogene RNAs can act as a 'sponge' through competitive binding of common miRNA, releasing or attenuating repression through sequestering miRNAs away from parental mRNA. In theory, ceRNAs refer to all transcripts such as mRNA, tRNA, rRNA, long non-coding RNA, pseudogene RNA a...
متن کاملLimitations of Pseudogenes in Identifying Gene Losses
The loss of previously established genes has been proposed as a major force in evolutionary change. While the sequencing of many new species offers the opportunity to identify cases of gene loss, the best method to do this with is unclear. A number of methods to identify gene losses rely on the presence of a pseudogene for each loss. If genes are completely or largely removed from the genome, h...
متن کاملPseudogenes
Pseudogenes are ubiquitous and abundant in genomes. Pseudogenes were once called "genomic fossils" and treated as "junk DNA" several years. Nevertheless, it has been recognized that some pseudogenes play essential roles in gene regulation of their parent genes, and many pseudogenes are transcribed into RNA. Pseudogene transcripts may also form small interfering RNA or decrease cellular miRNA co...
متن کاملGenes and pseudogenes in a reiterated rat tRNA gene cluster.
A 13.4 kb rat genomic DNA fragment containing two related tRNA gene clusters was isolated from a rat lambda recombinant and analyzed for gene arrangement and nucleotide sequence. One cluster was found to contain a tRNALeuCUG gene while the second contained a tRNALeuCUA pseudogene with multiple base substitutions. The tRNALeu gene was found to possess an intact coding region and a functional tra...
متن کاملStructure of gene and pseudogenes of human apoferritin H.
Ferritin is composed of two subunits, H and L. cDNA's coding for these proteins from human liver (1,2,3), lymphocytes (4) and from the monocyte-like cell line U937 (5) have been cloned and sequenced. Southern blot analysis on total human DNA reveals that there are many DNA segments hybridizing to the apoferritin H and L cDNA probes (1,2,4,6). In view of the tissue heterogeneity of ferritin mole...
