The science behind Lilac’s work is grounded in understanding RNA regulation beyond sequence alone. This section explores key concepts in RNA modification, low-input measurement, and translational relevance that shape how Lilac approaches RNA biology.

Unlocking RNA
Function

Sequence defines the potential. Modifications define the biological reality.

RNA is the cell’s most dynamic messenger. Beyond the genetic code, a hidden layer of chemical modifications—the epitranscriptome—governs RNA stability, localization, and translation. Lilac Biosciences delivers the precision tools required to map this regulatory layer.

Writers

Enzymes that deposit chemical modifications onto RNA.

Readers

Proteins that recognize and translate modifications into cellular function.

Erasers

Enzymes that remove modifications, enabling a dynamic and reversible system.

Why RNA modification measurement has lagged behind sequencing

While DNA and RNA sequencing have become routine, the chemical modifications that decorate RNA molecules present unique measurement challenges. Unlike the four standard bases, modifications are often transient and sub-stoichiometric, requiring highly sensitive and quantitative approaches that go beyond simple presence/absence detection.

 

Why low-input RNA workflows matter in translational studies

Translational research often relies on precious clinical specimens, such as needle biopsies or specific cell populations, where RNA quantity is severely limited. Traditional modification analysis methods typically require micrograms of material, which is often unattainable in clinical settings. Developing workflows that maintain quantitative accuracy with sub-nanogram inputs is essential for moving epitranscriptomics into the clinic.
