[The action of exogenous RNAse on the cells of lower eukaryotes]
Abstract:
We studied the mechanism of growth-stimulating effect of various compounds using an exogenous RNase-micromycete model and found that the treatment with microdoses of RNase intensified the reproduction of the yeast Candida valida and growth of Aspergillus fumigatus. At the same time the respiration activity of yeast cells and fungal mitochondria as well as succinate dehydrogenase activity increased. The secretion of total protein, cellulase and cellobiase changed in the presence of RNase in the growth medium. Electrophoretic mobility of Candida valida cells enhanced by 20%. The RNase stimulating effect on microbial cells seems to result from changes in characteristics of the cell surface.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
