Design of an N^7-Glycosylated Purine Nucleoside for Recognition of GC Base Pairs by Triple Helix Formation [PDF]
Pyrimidine oligodeoxyribonucleotides bind in the major groove of DNA parallel to the purine Watson-Crick strand by formation of specific hydrogen bonds between thymine and adenine (T•AT triplet) and protonated cytosine and guanine (C+GC triplet) on the ...

Non‐union and delayed fracture healing are major problems for patient treatment; biomarkers such as miRNA can help predicting complications. A systematic review approach identified key miRNA involved in non‐union or delayed fracture healing. Identification of the 6 most investigated miRNA in fracture healing with role in key pathways.

Reduction of Metal Ions by Boranephosphonate DNA [PDF]
Oligodeoxyribonucleotides bearing boranephosphonate linkages (bpDNA) were shown to reduce a number of metal ions and form nanoparticles through a novel reaction pathway that leads to phosphate diesters or phosphate triesters in water or alcohols ...

Mechanisms of chemical cleavage and isomerization of RNA phosphodiester bonds discussed as a contribution to conception of a plausible unified picture of bio‐catalytic RNA cleavage Abstract The cleavage of RNA phosphodiester bonds by RNase A and hammerhead ribozyme at neutral pH fundamentally differs from the spontaneous reactions of these bonds under ...

Chimerization of antibodies by isolation of rearranged genomic variable regions by the polymerase chain reaction [PDF]
We describe a new method for amplification, by polymerase chain reaction (PCR), of rearranged segments encoding the variable part of light and heavy chains of an antibody (Ab) from the chromosomal DNA of hybridoma cells for the chimerization ofAbs.

Core‐Shell DNA‐Cholesterol Nanoparticles Exert Lysosomolytic Activity in African Trypanosomes**
The bioengineering of synthetic nanoparticles with therapeutic potential for the treatment of African sleeping sickness is reported. The molecules are DNA‐cholesterol amphiphiles, which self‐assemble into micelle‐type nanoparticles with an exterior DNA shell and a lipid core. The particles are constructed to attack two parasite‐specific targets thereby

BLM–DNA2–RPA–MRN and EXO1–BLM–RPA–MRN constitute two DNA end resection machineries for human DNA break repair [PDF]
Repair of dsDNA breaks requires processing to produce 3′-terminated ssDNA. We biochemically reconstituted DNA end resection using purified human proteins: Bloom helicase (BLM); DNA2 helicase/nuclease; Exonuclease 1 (EXO1); the complex comprising MRE11 ...

Effects of an abasic site on triple helix formation characterized by affinity cleaving [PDF]
The stability of triple helical complexes of pyrimidine oligodeoxyribonucleotides containing one abasic 1,2- dideoxy-D-ribose (ø) residue was examined by affinity cleaving.
