Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Biological Consequences of Tightly Bent DNA: The Other Life of a Macromolecular Celebrity [PDF]

, 2006
The mechanical properties of DNA play a critical role in many biological functions. For example, DNA packing in viruses involves confining the viral genome in a volume (the viral capsid) with dimensions that are comparable to the DNA persistence length ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

An enhanced CRISPR repressor for targeted mammalian gene regulation. [PDF]

, 2018
The RNA-guided endonuclease Cas9 can be converted into a programmable transcriptional repressor, but inefficiencies in target-gene silencing have limited its utility.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Exploiting a Phage-Bacterium Interaction System as a Molecular Switch to Decipher Macromolecular Interactions in the Living Cell

Viruses, 2018
Pathogenicity islands of Staphylococcus aureus are under the strong control of helper phages, where regulation is communicated at the gene expression level via a family of specific repressor proteins.

Construction and utilisation of a bidirectional reporter vector in the analysis of two nod-boxes in of Rhizobium loti : a thesis presented in partial fulfilment of the requirements for the Degree of Master of Science in Molecular Genetics at Massey University [PDF]

, 1993
The nod-box is a 47bp cis-acting regulatory region which has been conserved amongst every species of Rhizobium studied to date. In species such as R. meliloti and R.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

YgaE Regulates Out Membrane Proteins in Salmonella enterica Serovar Typhi under Hyperosmotic Stress

The Scientific World Journal, 2014
Salmonella enterica serovar Typhi (S. Typhi) is a human-specific pathogen that causes typhoid fever. In this study, we constructed ΔygaE mutant and a microarray was performed to investigate the role of ygaE in regulation of gene expression changes in ...

Evidence That Runt Acts as a Counter-Repressor of Groucho During Drosophila melanogaster Primary Sex Determination

G3: Genes, Genomes, Genetics, 2020
Runx proteins are bifunctional transcription factors that both repress and activate transcription in animal cells. Typically, Runx proteins work in concert with other transcriptional regulators, including co-activators and co-repressors to mediate their ...
