Project description:A long form (tRNase ZL) of tRNA 3' processing endoribonuclease (tRNase Z, or 3' tRNase) can cleave any target RNA at any desired site under the direction of artificial small guide RNA (sgRNA). We discovered in human kidney 293 cell extracts various new small noncoding RNAs (ncRNAs) including 5'-half-tRNAs and 28S rRNA fragments, co-immunoprecipitated with tRNase ZL, and demonstrated that two of these ncRNAs work as sgRNAs for tRNase ZL in vivo as well as in vitro. In order to find genuine mRNA targets of tRNase ZL guided by ncRNAs, we performed DNA microarray analysis for mRNAs from the 293 cells transfected with the tRNase ZL expression plasmid, and found that PPM1F and DYNC1H1 mRNAs are its genuine targets.

Project description:tRNase ZL-utilizing efficacious gene silencing (TRUE gene silencing) is an RNA-mediated gene expression control technology that has therapeutic potential. This technology is based on the properties of tRNase ZL that it can cleave any target RNA at any desired site under the direction of an appropriate artificial small guide RNA (sgRNA) and that cytosolic tRNase ZL can modulate gene expression by cleaving mRNA under the direction of cellular 5′-half-tRNA or microRNA as sgRNA. In order to estimate a number of potential therapeutic heptamer-type sgRNAs for hematological malignancies, we constructed an sgRNA library composed of 156 heptamer-type sgRNAs, and examined how the sgRNAs affect viability of leukemia and myeloma cells. And we found that 20 of the 156 sgRNAs can efficiently induce apoptosis in at least one of the cancer cell lines. Furthermore, we demonstrated that 4 of the 20 effective sgRNAs can reduce growth rates of HL60 cells in mouse xenograft models. DNA microarray analysis for changes in an mRNA profile by these four heptamer-type sgRNAs suggested at least one candidate target mRNA that contains a potential tRNase ZL target site for each sgRNA.

Changes in gene expression in HL60 cells were measured after 18-hour incubation in the absence or presence of one of five different heptamer-type sgRNAs. *Heptamer sequences requested but not provided by submitter

Project description:Mitochondrial rRNAs play important roles in regulating mtDNA-encoded gene expression and energy metabolism subsequently. However, the proteins that regulate mitochondrial 16S rRNA processing remain poorly understood. Herein, we generated adipose-specific Wbscr16-/- mice and cells, both of which exhibited dramatic mitochondrial changes. Subsequently, WBSCR16 was identified as a 16S rRNA-binding protein essential for the cleavage of 16S rRNA-mt-tRNALeu, facilitating 16S rRNA processing and mitochondrial ribosome assembly. Additionally, WBSCR16 recruited RNase P subunit MRPP3 to nascent 16S rRNA and assisted in this specific cleavage. Furthermore, evidence showed that adipose-specific Wbscr16 ablation promotes energy wasting via lipid preference in brown adipose tissue, leading to excess energy expenditure and resistance to obesity. In contrast, overexpression of WBSCR16 upregulated 16S rRNA processing and induced a preference for glucose utilization in both transgenic mouse models and cultured cells. These findings suggest that WBSCR16 plays essential roles in mitochondrial 16S rRNA processing in mammals, and is the key mitochondrial protein to balance glucose and lipid metabolism.
