Streptomyces RNases – Function and impact on antibiotic synthesis
Frontiers in Microbiology, 2023 Streptomyces are soil dwelling bacteria that are notable for their ability to sporulate and to produce antibiotics and other secondary metabolites. Antibiotic biosynthesis is controlled by a variety of complex regulatory networks, involving activators ...

Synthesis of Polynucleotide Analogs Containing a Polyvinyl Alcohol Backbone
Molecules, 2008 Water soluble homo-base polynucleotide analogues were synthesized in whichpolyvinyl alcohol and partially phosphonated polyvinyl alcohol constituted the backbones,onto which were grafted uracil or adenine via 1,3-dioxane spacers formed by acetalformation

When DNA Polymerases Multitask: Functions Beyond Nucleotidyl Transfer
Frontiers in Molecular Biosciences, 2022 DNA polymerases catalyze nucleotidyl transfer, the central reaction in synthesis of DNA polynucleotide chains. They function not only in DNA replication, but also in diverse aspects of DNA repair and recombination.

Micro-RNAs of the miR-15 family modulate cardiomyocyte survival and cardiac repair [PDF]
, 2015 A family of microRNAs, called the miR-15 family, which includes miR-195, are shown to be up-regulated during pathological cardiac remodeling and repress the expression of mRNAs required for cell proliferation and survival, with consequent loss of ...

Micro-RNA family that modulates fibrosis and uses thereof [PDF]
, 2017 The present invention relates to the identification of a microRNA family, designated miR-29a-c, that is a key regulator of fibrosis in cardiac tissue. The inventors show that members of the miR-29 family are down-regulated in the heart tissue in response

Molecules, 2012 We report herein the synthesis and characterization of 9-(2-diallylaminoethyl) adenine. We evaluated two different synthetic routes starting with adenine where the optimal route was achieved through coupling of 9-(2-chloroethyl)adenine with diallylamine.

Carbethoxylation of Polynucleotides [PDF]
European Journal of Biochemistry, 1971 Diethyl pyrocarbonate has been shown to react with poly(A), poly(C) and poly(G) but poly(U) does not react. Diethyl pyrocarbonate appears to carbethoxylate amino groups on the bases. Poly(A) can bind one carbethoxy group per base but the binding capacity of poly(G) and poly(C) under non‐denaturing conditions is 0.32 and 0.23, respectively.

Specific recognition of a multiply phosphorylated motif in the DNA repair scaffold XRCC1 by the FHA domain of human PNK. [PDF]
, 2009 Short-patch repair of DNA single-strand breaks and gaps (SSB) is coordinated by XRCC1, a scaffold protein that recruits the DNA polymerase and DNA ligase required for filling and sealing the damaged strand.

Long‐chain polynucleotide filler for skin rejuvenation: efficacy and complications in five patients
Dermatologic Therapy, 2016 Aging well has become the new target of preventative medicine, and aesthetic dermatology can contribute to this request. The polynucleotide (PN) containing products not only fill the space, but improve tissue regeneration, resulting in more natural ...
