Interplay of noncoding RNAs,mRNAs, and proteins during the growth of eukaryotic cells

Numerous biological functions of noncoding RNAs (ncRNAs) in eukaryotic cells are based primarily on their ability to pair with target mRNAs and then either to prevent translation or to result in rapid degradation of the mRNA-ncRNA complex. Using a general model describing this scenario, we show that ncRNAs may help to maintain constant mRNA and protein concentrations during the growth of cells. The possibility of observation of this effect on the global scale is briefly discussed.
