mitochondrial DNA and RNA
Opis:: To reveal nucleic acid localization in mitochondria, we designed molecular beacon fluorescent probes against: i) the light strand complementary to ND5 mitochondrial DNA (mtDNA) gene (annealing also to corresponding mRNA); ii) displacement (D) loop 7S DNA (annealing also to parallel heavy strand mtDNA and corresponding light strand transcript); iii) the proximal D-loop heavy strand displaced by the light strand promoter minor RNA. Confocal microscopy demonstrated ND5 probe spreading (less for other probes) in mitochondrial reticulum tubules but upon RNase A treatment all probes contoured mtDNA nucleoid localization. DNase I spread the signal over mitochondrial tubules. Future applications are discussed.

Leber hereditary optic neuropathy
Opis:: We have analysed the heteroplasmy level in 11 individuals from 3 families harbouring the mitochondrial 11778A mutation responsible for Leber hereditary optic neuropathy using last cycle hot PCR. The mutation level exceeded 90% both in affected and in unaffected individuals. We also checked whether any of the families belonged to the J haplogroup of mitochondrial DNA and obtained a negative result.

Tytuł:: Participation of non-coding RNAs in plant organelle biogenesis
Autorzy:: Rurek, Michal
Powiązania:: https://bibliotekanauki.pl/articles/1038718.pdf
Data publikacji:: 2016
Wydawca:: Polskie Towarzystwo Biochemiczne
Tematy:: non-coding RNAs
chloroplast DNA
mitochondrial DNA
organelle gene expression
stress response
Opis:: The biogenesis of plant mitochondria and plastids is a multistep process that depends on the expression of both, organellar and nuclear genes. A growing body of evidence suggests that the indispensable coordination of different steps in this process may be gained by participation of the non-coding RNAs. A plethora of non-coding RNAs of diverse length, both intraorganellar ones, as well as encoded by the nuclear genome (including microRNAs and short interfering RNAs), were also suggested to play a role in the stress response by regulating the expression levels of targeted genes important for organelle biogenesis. Selected points of current interest regarding the regulation of plant mitochondrial and plastid gene expression by diverse non-coding RNAs, also discussed in the aspect of abiotic stress conditions, are highlighted here.
