Pioneering New Discoveries in the Central Dogma of Life

"The Ribosome is Life"

Here, the ribosome is portrayed as a beating heart, with mRNA strands extending like veins. Roughly 10 million of these molecular machines in each cell decode the genome into the proteins that make life possible. Our lab's discovery is that the ribosome is a regulatory machine.

“In the Barna Lab we believe that ribosomes are not just machines, they are regulators of life.”

Translation is not the endpoint of gene expression — it is its point of commitment. While transcription defines possibility, translation determines reality by selecting which molecular instructions become biological function. Ribosomes do not merely execute genetic information; they integrate cellular state, developmental context, metabolic inputs, and regulatory signals to generate selective protein production programs that shape identity, fate, and physiology.

Concept

From Uniform Machines ➔ Specialized Regulators

For decades, ribosomes were viewed as invariant molecular machines-identical entities carrying out rote, housekeeping functions in translating all mRNAs with little regulation.

Our work helped change this view.

We demonstrated that ribosomes can differ in composition and function, giving rise to specialized translation programs that selectively control gene expression.

These programs shape cell fate, developmental transitions,tissue regenertation, human traits and adaptive responses in diseases.

Gene expression is therefore not only encoded in mRNA it is also encoded in the ribosome itself. Ribosomes themselves encode regulatory information that shapes development, regeneration, and disease.

Why this Matters

Translation shapes:

embryonic development
tissue regeneration
cancer
neurodegeneration
aging
ribosomopathies

The Barna Lab studies how ribosomes and translation control shape cell identity, development, and disease.

Our Vision

We are redefining the ribosome as a regulatory platform.

Rather than acting as passive protein synthesis machines, ribosomes can differ in composition, associated factors, RNA features, chemical modifications, subcellular localization, and translational output. These differences can create specialized ribosome populations that coordinate gene expression programs with cellular state, tissue context, and physiological demand.

This concept opens new ways to understand development, regeneration, cancer, aging, metabolism, and human disease. It also raises fundamental questions: How are specialized ribosomes generated? How do they choose their mRNA targets? How do they localize to specific cellular compartments? How do they respond to stress or developmental signals? And how can their functions be manipulated to change cell fate or disease outcome?

What We Study

Ribosome Specialization

We investigate how differences in ribosomal proteins, ribosome-associated proteins, rRNA variants, rRNA modifications, and ribosome composition create functionally distinct ribosome populations. These specialized ribosomes can control selective translation and provide a powerful layer of regulation beyond transcription.

Spatial Translation

Cells are not uniform environments. We study how ribosomes are organized at specific subcellular locations, including the endoplasmic reticulum, mitochondria, lipid droplets, neuronal compartments, and developmental signaling centers. By mapping where translation occurs, we uncover how local protein synthesis coordinates cellular architecture, metabolism, and fate.

Development and Cell Fate

We explore how translational control guides embryonic development, stem cell transitions, tissue patterning, and lineage specification. Our work seeks to understand how ribosomes help cells execute precise developmental programs and how disruptions in this process contribute to disease.

Disease, Aging, and Regeneration

Ribosome-mediated gene regulation is deeply connected to human health. We study how altered translation contributes to cancer, ribosomopathies, neurodevelopmental disorders, metabolic disease, aging, and tissue repair. Our long-term goal is to identify new therapeutic opportunities by targeting the translational machinery with greater precision.

Technology Development

Many of the questions we ask require tools that did not previously exist. We develop and apply new technologies to study ribosome function, translation, RNA regulation, and spatial gene expression with molecular and cellular resolution. These approaches allow us to directly interrogate how ribosomes operate in living cells, tissues, and organisms.

Our Technologies

The Barna Lab develops innovative platforms to reveal how translation is regulated in space, time, and context.

Ribo-Tweezer enables selective removal of specific ribosomal proteins from mature ribosomes, allowing us to directly test the function of individual ribosome components without disrupting other functions.

ALIBi allows light-controlled labeling and isolation of ribosomes from defined cellular regions, making it possible to study local translation at specific subcellular sites.

RiboExM uses expansion microscopy to visualize individual ribosomes and their spatial organization within cells and tissues.

RAPIDASH enables the identification of ribosome-associated proteins without the need for genetic tagging.

RIBO-RT and SWITCH-seq allow long-read analysis of rRNA variants and ribosome-associated RNA features.

Together, these technologies provide new ways to uncover how ribosomes regulate gene expression with spatial, molecular, and functional precision.

Why It Matters

Translation shapes the biology of:
embryonic development · tissue regeneration · cancer · neurodegeneration · aging · ribosomopathies · metabolism

The regulation of protein synthesis is one of the most powerful and least understood layers of gene expression. While transcription determines which RNAs are produced, translation determines which proteins are actually made. This makes the ribosome a central point of control over cellular behavior.

By revealing how ribosomes specialize and regulate translation, we aim to transform our understanding of gene expression and uncover new mechanisms that drive development, physiology, and disease.

Our work suggests that ribosomes are not simply the endpoint of gene expression. They are active regulatory engines that help define what cells become, how tissues function, and how organisms adapt.

Stories About our Work

At Barna Lab, we delve into the intricate role of ribosomes in cellular regulation and their impact on health and disease. Our team is dedicated to pioneering research that not only advances understanding of translation processes but also translates these findings into therapeutic strategies. By investigating how ribosomal function affects cellular outcomes, we aim to develop innovative treatments for conditions such as cancer, neurodegeneration, aging and enhance our knowledge of ribosomopathies. Join us in exploring the frontiers of molecular biology.

For decades, biology has focused on how genes are regulated at the level of transcription, chromatin, and epigenetics. Our work has helped reveal a new frontier: the ribosome itself can regulate gene expression.

This discovery opens a previously hidden layer of biological control—one that shapes development, regeneration, and disease. By supporting the Barna Lab, you help advance a transformative area of research that has the potential to unlock entirely new therapeutic strategies for cancer, neurodegeneration, aging, and ribosomopathies.
