The Emerging Value of Circular Noncoding RNA Research in Cancer Diagnosis and Treatment.

Circular RNAs (circRNA) are a recently described class of RNA molecules that have attracted substantial attention as new components of disease mechanisms and as potential biomarkers in multiple diseases, including cancer. CircRNAs are often highly conserved and exhibit developmental stage- and disease-specific expression. Several studies have reported circRNA expression patterns that are associated with specific cancer types and with patient prognosis.

BML-257, a Small Molecule that Protects against Drug-Induced Liver Injury in Zebrafish.

The use of many essential drugs is restricted due to their deleterious effects on the liver. Molecules that can prevent or protect the liver from drug-induced liver injury (DILI) would be invaluable in such situations. We used a transgenic line in zebrafish with a hepatocyte-specific expression of bacterial nitroreductase to cause temporally controlled liver damage.

A Temporal Map of Gene Expression Pattern During Zebrafish Liver Regeneration.

Zebrafish is increasingly being used to study liver injury and regeneration. However, very little is known about molecular players that respond to injury and those important for liver regeneration. We use a metronidazole nitroreductase (MTZ-)-based system to selectively ablate hepatocytes in adult zebrafish to create a model for liver injury and regeneration.

A novel gene-diet pair modulates C. elegans aging.

Diet profoundly affects metabolism and incidences of age-related diseases. Animals adapt their physiology to different food-types, modulating complex life-history traits like aging. The molecular mechanisms linking adaptive capacity to diet with aging are less known.

Genome-wide endogenous DAF-16/FOXO recruitment dynamics during lowered insulin signalling in C. elegans.

Lowering insulin-IGF-1-like signalling (IIS) activates FOXO transcription factors (TF) to extend life span across species. To study the dynamics of FOXO chromatin occupancy under this condition in C. elegans, we report the first recruitment profile of endogenous DAF-16 and show that the response is conserved.
