Chemistry of Peptide-Oligonucleotide Conjugates: A Review

open access: yesMolecules, 2021
Peptide-oligonucleotide conjugates (POCs) represent one of the increasingly successful albeit costly approaches to increasing the cellular uptake, tissue delivery, bioavailability, and, thus, overall efficiency of therapeutic nucleic acids, such as ...

Optimization of synthetic route to PNA-T-OH monomers [PDF]

open access: yes, 2018
Peptide nucleic acids are synthetic molecules crafted to mimic natural nucleic acids, and thus, they are widely utilized in many chemical, and, biomedical applications.

Study of E. coli Hfq's RNA annealing acceleration and duplex destabilization activities using substrates with different GC-contents [PDF]

open access: yes, 2012
Folding of RNA molecules into their functional three-dimensional structures is often supported by RNA chaperones, some of which can catalyse the two elementary reactions helix disruption and helix formation.

The solution supramolecular structure of α2 → 8 polysialic acid suggests a structural cause for its low immunogenicity

open access: yesFEBS Letters, EarlyView.
α2 → 8 polysialic acid elicits poor immunogenicity. Small‐angle scattering shows a supramolecular structure with parallel‐chain binding, although in different forms at μm and mm calcium. The major histocompatibility complex requires molecular weights around 2000 Da to produce antibodies, and 2000 Da polysialic oligomers will bind in these structures ...

Exact and efficient calculation of Lagrange multipliers in constrained biological polymers: Proteins and nucleic acids as example cases [PDF]

open access: yesJournal of Computational Chemistry 32 (2011) 3039-3046, 2011
In order to accelerate molecular dynamics simulations, it is very common to impose holonomic constraints on their hardest degrees of freedom. In this way, the time step used to integrate the equations of motion can be increased, thus allowing, in principle, to reach longer total simulation times.

Structure and function of the Rad9-binding region of the DNA-damage checkpoint adaptor TopBP1 [PDF]

open access: yes, 2010
TopBP1 is a scaffold protein that coordinates activation of the DNA-damage-checkpoint response by coupling binding of the 9-1-1 checkpoint clamp at sites of ssDNA, to activation of the ATR-ATRIP checkpoint kinase complex.

The roles and applications of extracellular vesicles in cancer

open access: yesMolecular Oncology, EarlyView.
Extracellular vesicles (EVs) are minute versions of cells limited by a lipid bilayer containing cytoplasm from the cell that releases them, but without a nucleus and thus unable to self‐reproduce. EVs contain multiple molecules (proteins, lipids, glycans, and nucleic acids) they can induce complex responses in cells.

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

open access: yesMolecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

Evaluation of the Protein Recognition Properties of Peptide Nucleic Acids [PDF]

open access: yes, 2015
The objective is to evaluate the ability of aminoacyl-tRNA synthetases (aaRS) to recognize the non-standard nucleic acid, PNA (peptide nucleic acid). PNA has immense potential in biomedical applications due to its increased thermostability and nuclease ...
