Mechanisms of base selection by the E.coli mispaired uracil glycosylase [PDF]

, 2008
The repair of the multitude of single-base lesions formed daily in the cells of all living organisms is accomplished primarily by the base-excision repair (BER) pathway that initiates repair through a series of lesion-selective glycosylases.

Electrophilic oligodeoxynucleotide synthesis using dM-Dmoc for amino protection

Beilstein Journal of Organic Chemistry, 2019
Solid-phase synthesis of electrophilic oligodeoxynucleotides (ODNs) was achieved using dimethyl-Dmoc (dM-Dmoc) as amino protecting group. Due to the high steric hindrance of the 2-(propan-2-ylidene)-1,3-dithiane side product from deprotection, the use of

Immunosuppressive Formulations for Immunological Defense against Traumatic Brain Injury

Advanced Healthcare Materials, EarlyView.
A novel subcutaneous formulation combining alpha‐ketoglutarate, glycolysis inhibitor PFK15, and a myelin peptide reduces inflammation in a mouse TBI model. This formulation promotes regulatory immune cells, enhances autophagy, and improves motor function, suggesting its potential as a prophylactic immunosuppressive therapy to mitigate TBI‐induced ...

Circular siRNAs for Reducing Off-Target Effects and Enhancing Long-Term Gene Silencing in Cells and Mice

Molecular Therapy: Nucleic Acids, 2018
Circular non-coding RNAs are found to play important roles in biology but are still relatively unexplored as a structural motif for chemically regulating gene function. Here, we investigated whether small interfering RNA (siRNA) with a circular structure

Engineering CAR‐T Therapeutics for Enhanced Solid Tumor Targeting

Advanced Materials, EarlyView.
CART cell therapy has proven effective for blood cancers but struggles with solid tumors due to diverse antigens and complex environments. Recent efforts focus on improving CAR design and validation platforms. Advances in protein engineering, machine learning, and organoid systems aim to enhance CAR‐T therapy against solid tumors.

Profiling the Mismatch Tolerance of Argonaute 2 through Deep Sequencing of Sliced Polymorphic Viral RNAs

Molecular Therapy: Nucleic Acids, 2017
Low allelic and clonal variability among endogenous RNAi targets has focused mismatch tolerance studies to RNAi-active guide strands. However, the inherent genomic instability of RNA viruses such as hepatitis C virus (HCV) gives rise to quasi-species ...
