When R‐Loops Go Awry: Genome Instability and Neurological Diseases

European Journal of Neuroscience, Volume 63, Issue 8, April 2026.
DNA normally exists as a double helix formed by two complementary strands. During gene transcription, however, one strand of DNA can bind to RNA, causing the other DNA strand to be displaced. This creates a structure called an R‐loop. R‐loops play important roles in normal cellular processes such as gene expression, DNA replication, and transcription ...

Defining the high-translational readthrough stop codon context. [PDF]

PLoS Genet
Translational termination is not entirely efficient and competes with elongation, which might result in translational readthrough (TR). TR occurs when a near-cognate tRNA binds to a stop codon, (mis)interpreting it as a sense codon and producing a C-terminal extension of the protein.

Programming Next‐Generation Synthetic Biosensors by Genetic Circuit Design

Advanced Science, Volume 13, Issue 14, 9 March 2026.
Synthetic biology enables genetic circuit‐based biosensing to detect diverse targets, process signals, and transduce them into readable outputs or intracellular regulatory activities. However, field deployment and real‐world application of such synthetic biosensors face considerable challenges in sensitivity, specificity, speed, stability, and ...

Unraveling the role of TP53 mutations in myeloproliferative neoplasms: Molecular mechanisms of leukemic transformation

HemaSphere, Volume 10, Issue 3, March 2026.
Abstract TP53 mutations are found in over 50% of tumor types, including myeloproliferative neoplasms (MPNs). MPNs are characterized by a chronic phase, which may progress to secondary acute myeloid leukemia (sAML). Here, we discuss the physiological functions of p53 in hematopoiesis and its deregulation in MPNs.

Nonsense Suppression as an Approach to Treat Lysosomal Storage Diseases

Diseases, 2016
In-frame premature termination codons (PTCs) (also referred to as nonsense mutations) comprise ~10% of all disease-associated gene lesions. PTCs reduce gene expression in two ways.

Metabolic Stroke: Atypical Presentation of Succinic Semialdehyde Dehydrogenase Deficiency

JIMD Reports, Volume 67, Issue 2, March 2026.
ABSTRACT Succinic semialdehyde dehydrogenase (SSADH) deficiency is a rare autosomal recessive neurometabolic disorder caused by biallelic pathogenic variants in ALDH5A1, encoding the mitochondrial enzyme SSADH. This enzyme catalyses the conversion of succinic semialdehyde to succinic acid in the γ‐aminobutyric acid (GABA) degradation pathway.

Readthrough Acetylcholinesterase Is Increased in Human Liver Cirrhosis

PLoS ONE, 2012
There have been many studies on plasma butyrylcholinesterase in liver dysfunction. However, no data is available about acetylcholinesterase in human cirrhosis, although profound changes have been described in cirrhotic rat models.Human serum and liver acetylcholinesterase and its molecular forms were determined enzymatically, after ...

Advances in therapeutic use of a drug-stimulated translational readthrough of premature termination codons

Molecular Medicine, 2018
Premature termination codons (PTCs) in the coding regions of mRNA lead to the incorrect termination of translation and generation of non-functional, truncated proteins.

Translational readthrough goes unseen by natural selection [PDF]

, 2019
AbstractOccasionally during protein synthesis, the ribosome bypasses the stop codon and continues translation to the next stop codon in frame. This error is called translational readthrough (TR). Earlier research suggest that TR is a relatively common error, in several taxa, yet the evolutionary relevance of this translational error is still unclear ...

Overlapping enhancer/promoter and transcriptional termination signals in the lentiviral long terminal repeat

Retrovirology, 2007
Oncoretrovirus, but not lentivirus, displays a high transcriptional readthrough activity in the 3' long terminal repeat (LTR) (Zaiss et al. J. Virol. 76, 7209–7219, 2002). However, the U3-deleted, self-inactivating (SIN) lentiviral LTR also exhibits high
