A requirement for PARP-1 for the assembly or stability of XRCC1 nuclear foci at sites of oxidative DNA damage [PDF]

, 2003
The molecular role of poly (ADP-ribose) polymerase-1 in DNA repair is unclear. Here, we show that the single-strand break repair protein XRCC1 is rapidly assembled into discrete nuclear foci after oxidative DNA damage at sites of poly (ADP-ribose ...

Neurodevelopmental features in KCNQ2 developmental and epileptic encephalopathy may have limited associations with KV7.2 dysfunction

Epilepsia Open, EarlyView.
Abstract Objective Variants in KCNQ2 encoding the voltage‐gated potassium channel KV7.2 are associated with developmental and epileptic encephalopathy (DEE) of varying severity. This study examined the relationship of KCNQ2 variant dysfunction with the neurodevelopmental phenotype of individuals with KCNQ2‐DEE. Methods A parent‐reported survey gathered

Using generalized quantitative structure–property relationship (QSPR) models to predict host cell protein retention in ion‐exchange chromatography

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Selecting an optimal chromatography resin during biopharmaceutical downstream process development is a great challenge. This is especially the case for recombinant subunit vaccines, where product properties vary greatly and recovery often involves cell lysis, which yields a complex mixture of different host cell materials. Host cell

Precision mRNA Delivery via Ultrasound‐Controlled Release Perfluorocarbon Emulsions: An Innovative Ultrasound Theranostic Strategy with 19F MRI Feasibility

Small, EarlyView.
A key challenge in advancing messenger RNA (mRNA) therapeutics in cardiovascular diseases lies in achieving controlled release at the precise site within the vasculature. This study presents the development of perfluorocarbon nanodroplets with exceptional theranostic potential, enabling real‐time tracking through ultrasound and fluorine‐19 (19F ...

Comprehensive characterization of glutamine synthetase-mediated selection for the establishment of recombinant CHO cells producing monoclonal antibodies [PDF]

, 2018
To characterize a glutamine synthetase (GS)-based selection system, monoclonal antibody (mAb) producing recombinant CHO cell clones were generated by a single round of selection at various methionine sulfoximine (MSX) concentrations (0, 25, and 50 μM ...
