microRNA biomarkers of toxicity

The term toxomiR® refers to a selection of 19 microRNAs that are enriched in various tissues. Toxicant-induced changes in the transcription and secretion of toxomiRs® are highly sensitive to toxic effects occuring in the liver, kidney, central nervous system, heart, muscle, lung, pancreas, vascular injury, and due to endocrine disruption. ToxomiRs® can be analyzed in serum or plasma.

This review recently published, gives detailed insight into the clinical utility of circulating microRNAs as biomarkers of toxicity.

the toxomiR® panel are available as in-house service by TAmiRNA

non-invasive screening of toxic effects using serum or plasma

microRNAs in human biofluids for early detection of tissue injury after exposure to toxic substances.

Cross-species application is possible due the high sequence conservation.

rapid and robust solution to quantify toxic effects in human plasma samples

customization is possible: upon request the analysis can be targeted to a specific set of microRNAs/tissue

service requirements

Frozen serum or plasma sample aliquots of at least 200 μl.

intended use

toxomiRs® can be used in pre-clinical and clinical phases of drug safety assessment. The microRNAs panel enable early and reliable detection as well as monitoring of adverse events.

The toxomiR® panel can be used:

  • to understand toxic mechanisms in liver, kidney, central nervous system, heart, muscle, lung, pancreas, vascular injury, and due to endocrine disruption
  • for identifying and monitoring safety risks in drug development
  • for early detection of tissue injury

frequently asked questions (FAQ)

Upon request the analysis can be targeted to a specific set of microRNAs/tissue.

The toxomiR® panel is intended to be used with human samples. However, orthologs for toxomiR® do exist in other species, allowing the use of adapted version of the Panel in non-mammalian species. To assess the feasibility of such projects, please contact us.

5 control primers to monitor assay and sample quality are included in the panel.

TAmiRNA´s toxomiR® panel has been standardized to a volume of 200 µL plasma as starting material to ensure high RNA yield and prevent inhibition of downstream PCR amplification using the Serum/Plasma RNA extraction kit.
