RNases H are ubiquitous enzymes that hydrolyse the RNA of a DNA/RNA hybrid. They are found in all kingdoms. They participate in the removal of RNA primers of Okazaki fragments. A role in transcription also suspected. RNases H are divided in two classes : class I and class II. RNases HI are nuclear whereasRNases HII are cytoplasmic and mitochondrial. RNases H are also known to be implicated in antisens effects of oligodeoxyribonucleotides. To help in designing new antisens molecules and to possess a new classification criterion, we have analysed the first cuts of these enzymes on various hybrids of 20 nucleotides in length. The tested RNases HI (from bovine and human origin) prefers the 3' end of the RNA engaged in a hybrid whereas RNases HII cut preferentially at 6 and 8 nucleotides from the 5' end of the same RNAs. Moreover informations on mitochondrial localisation of RNases HII has been obtained using this new classification criterion. After this, we have attempted to clone an RNase HII gene from the protozoan Leishmania mexicana amazonensis. This attempt did not succeed. Nowadays, only a few inhibitors of the RNase H activity are known. A good mean to obtain such inhibitors is to use SELEX strategies. We have made an in vitro selection of single stranded DNA aptamers against human recombinant RNase HII. One, b33 inhibited RNaseHII with an IC50 value of 120 nM. This inhibition was specific for eukaryotic RNases HII. B33 could fold into an imperfect stem-loop structure. The second aptamer, b12 poorly inhibited human RNase HII. Moreover several structures could be formed implicating G-quartet formation

During S phase, DNA replication starts at multiple origins distributed throughout the genome. As the replication machinery (or replisome) progresses throughout the DNA, it often encounters obstacles such as DNA secondary structures or transcription complexes, thereby generating what is called replication stress. Stalled replisomes are fragile structures that can give rise to chromosome breaks and trigger genome instability. When RNA polymerases stall, the nascent RNA can potentially anneal with the template DNA strand, creating a three-strand structure called R-loop. Coordination between replication and transcription in S phase limits the risks of collisions between the replisome and RNA polymerases. Even though, physiological transcription level and R-loops accumulation lead to recombination events in S phase. Type 1 and 2 ribonucleases H (RNase H) are specific proteins involved R-loops’ resolution through the degradation of the RNA strand within the RNA:DNA duplex. In the absence of RNases H, cells accumulate R-loops and are extremely sensitive to different replication stress-inducing genotoxic agents (e.g. MMS: methyl methanesulfonate or HU: hydroxyurea).The goal of my PhD project was to assess the roles of RNases H in the cellular response to replication stress. Using two cellular models, the budding yeast S. cerevisiae and mammalian cells, we demonstrated that RNases H mutations induce HU- and MMS-stalled replication forks processing and restart defects. Analysis of separation-of-function RNase H2 mutants suggests that it is the RNA:DNA hybrids removal activity of RNase H2 that is important for the correct processing of stalled forks experiencing replication stress. Indeed, quantification of RNA:DNA hybrids during the cell cycle reveals a higher level of hybrids in S phase in the presence of exogenous replication stress in both wild-type and RNases H-depleted cells. Moreover, our results demonstrate that the inhibition of transcrip tion or the overexpression of the RNA:DNA helicase Senataxin restore stalled replication fork processing and restart upon MMS treatment when cells lack RNase H2 activities. Altogether, our data indicate that Ribonucleases H1 and 2 and Senataxin helicase cooperate to resolve RNA polymerases and/or RNA:DNA hybrids interferences with replication
Pâtureau, Bénédicte Marie. "Induction of rnase H activity by arabinose-peptide nucleic acids". Thesis, McGill University, 2005. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=98763.
This thesis highlights the synthesis of the 5'-amino nucleoside analogue required for the incorporation of the peptide nucleic acid in both 2'-fluoroarabinonucleic acid (2'F-ANA) and DNA. Circular dichroism experiments afforded information on the hybrid conformation in solution, whereas UV thermal melting studies provided a measure of the thermal stability of such hybrid duplexes. Finally, ability of various linker modified AON/RNA hybrids to activate the RNase H enzyme was evaluated in parallel with the corresponding native unmodified DNA/RNA hybrids.
Incorporation of a PNA residue within DNA or 2'-FANA did not afford improvement in neither thermal stability nor enzymatic cleavage (except for homopolymeric sequences vs DNA) as compared to control or butyl-sequences.
