Evidence that microRNA precursors, unlike other non-coding RNAs, have lower folding free energies than random sequences
MOTIVATION Most non-coding RNAs are characterized by a specific secondary and tertiary structure that determines their function. Here, we investigate the folding energy of the secondary structure of non-coding RNA sequences, such as microRNA precursors, transfer RNAs and ribosomal RNAs in several eukaryotic taxa. Statistical biases are assessed by a randomization test, in which the predicted mi...
متن کاملNo evidence that mRNAs have lower folding free energies than random sequences with the same dinucleotide distribution.
This work investigates whether mRNA has a lower estimated folding free energy than random sequences. The free energy estimates are calculated by the mfold program for prediction of RNA secondary structures. For a set of 46 mRNAs it is shown that the predicted free energy is not significantly different from random sequences with the same dinucleotide distribution. For random sequences with the s...
متن کاملmRNAs have greater negative folding free energies than shuffled or codon choice randomized sequences.
An examination of 51 mRNA sequences in GenBank has revealed that calculated mRNA folding is more stable than expected by chance. Free energy minimization calculations of native mRNA sequences are more negative than randomized mRNA sequences with the same base composition and length. Randomization of the coding region of genes yields folding free energies of less negative magnitude than the orig...
متن کاملThe Role of Long Non-Coding RNAs in Ovarian Cancer
Background: Ovarian cancer is the most fatal tumor of female's reproductive system, and several genetics and environmental factors are involved in its development. Various studies have already identified suitable biomarkers to facilitate the early detection, prognosis evaluation, and the assessment of treatment response. However, the aim of this review was to investigate the role of long non-co...
متن کاملHide and Seek: Protein-coding Sequences Inside “Non-coding” RNAs
Muscle cells are critically dependent on calcium homeostasis. Without having the right amount of calcium ions just on the spot and coordinated in between muscle cells, no contraction can take place. Therefore, calcium homeostasis is one of the critical regulatory mechanisms in all muscle cells, including skeletal muscle and heart [1,2]. Sarco-endoplasmic reticulum Ca adenosine triphosphatase (S...
