In silico characterization of the family of PARP-like poly(ADP-ribosyl)transferases (pARTs)

open access: yesBMC Genomics, 2005
Background ADP-ribosylation is an enzyme-catalyzed posttranslational protein modification in which mono(ADP-ribosyl)transferases (mARTs) and poly(ADP-ribosyl)transferases (pARTs) transfer the ADP-ribose moiety from NAD onto specific amino acid side ...

Dual‐Key Genetic Circuit Enables Stable and Self‐Regulated Engineered Bacteria for the Treatment of Ulcerative Colitis

open access: yesAdvanced Science, EarlyView.
A self‐regulated Escherichia coli Nissle 1917 strain equipped with a dual‐key genetic circuit achieved antibiotic‐free stability and programmable lysis for therapeutic protein delivery. By co‐expressing an IL‐2 mutant and Amuc_1100, the engineered bacteria restored immune balance and epithelial integrity, providing a safe and precise approach for ...

Genetic relationships and epidemiological links between wild type 1 poliovirus isolates in Pakistan and Afghanistan

open access: yesVirology Journal, 2012
Background/Aim Efforts have been made to eliminate wild poliovirus transmission since 1988 when the World Health Organization began its global eradication campaign. Since then, the incidence of polio has decreased significantly.

Genetic Control of Tissue Remodeling by a Non‐Coding SNP in ITGA8 Explains Carotenoid‐Based Color Polymorphism in Marine Mollusks

open access: yesAdvanced Science, EarlyView.
In this study, the orange‐muscle giant abalone (Haliotis gigantea) is used as a model to identify a non‐coding SNP that disrupts the interaction between ITGA8 pre‐mRNA and the splicing factor ILF2, leading to altered ITGA8 splicing. These splicing changes promote carotenoid accumulation in abalone muscle through the regulation of tissue remodeling ...

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

open access: yesAdvanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Evolution of Prime Editing: Enhancing Efficiency and Expanding Capacity

open access: yesAdvanced Science, EarlyView.
Most rare diseases are caused by genetic mutations. Prime editing (PE) has emerged as a versatile tool capable of inducing diverse mutations without generating DNA double‐strand breaks. Despite its significant clinical potential, PE faces limitations in terms of efficiency and scalability.
