Our primary focus is to design and develop RNA therapies for liver diseases. Using humans as the model, we use an approach called deep phenotyping to explore the relationships between cells, genes, biological pathways and patterns of disease. At present, we test discarded human livers deemed not good enough for transplant.
What are the main challenges currently faced in the treatment of chronic liver diseases, and how does Resolution Therapeutics aim to address these challenges? Once a patient develops advanced cirrhosis/end-stage liver disease there are no specific therapies to significantly avoid major decompensations and death in the next few years.

Ras- G TPase-activating protein (SH 3 domain)- b inding p roteins (G3BP) are RNA binding proteins that plays a critical role in stress granule (SG) formation. Recent evidence suggests that G3BPs can also regulate mRNA expression through interactions with RNA outside of SGs.
The peak number of trials in the last five years and the regulatory approvals of three additional disease-modifying treatments for ALS in the previous eight years signal cause for hope that, as a community, we have the potential to transform this progressive and ultimately terminal neurodegenerative disorder into a treatable condition.
In nature, proteins take millions and trillions of years to evolve, 1 but scientists do not have this time when designing drugs for life-threatening diseases. Therefore, researchers use directed protein evolution technologies , to evolve and design proteins with specific functions under well-defined conditions and a practical time frame.
Through phylogenetic analysis and microscopy techniques, they identified a nuclear-encoded apicoplast RNA polymerase σ subunit called ApSigma. The study suggests that this regulatory system could be a potential target for future malaria treatments, offering hope for combatting this deadly disease that affects millions worldwide.
A few years ago, at Arrakis Therapeutics, we set out to conquer a strange new territory, drugging RNA structures with small molecules. In fact, it was these early pharmaceutical successes that gave us the confidence that we would ultimately succeed in systematically drugging a wide range of RNA structures.
Credit: OpenStax College The innate immune system has been evolutionarily successful for three reasons: its tools target the most fundamental properties of viruses , act as prophylactics —meaning they prevent diseases, rather than treat them—and are widespread. Existing medicines only pose a partial solution.
In the quest to combat and eradicate diseases, scientists and researchers are increasingly turning to the immense potential of artificial intelligence (AI) as a tool. It was here that the Impact Medicine Fund was raised as a concept around wellness for those with disease, with the ambition of unlocking some of this vast potential.
The amended protocol being implemented for all ongoing adult and adolescent fitusiran clinical studies was presented today at the 14 th Annual Congress of the European Association for Haemophilia and Allied Disorders (EAHAD). We stand by the few who suffer from rare diseases and the millions with long-term chronic conditions.
Abstract Chronic rhinosinusitis (CRS) is an inflammatory disease of paranasal sinuses. CRS rabbit models were constructed by Staphylococcus aureus infection and rabbits were injected with lentiviral vectors of short hairpin RNA-targeting Chemerin (shChemerin), followed by micro-computed tomography (CT) scan.
Physicians working in the early 20th century had little choice but to treat the world’s most rampant infectious disease with methods such as these. But even now, more than a century later, TB remains the deadliest infectious disease on Earth, killing about 1.2 million people every year. tuberculosis.
Introduction Messenger RNA (mRNA) technology has emerged as one of the most significant medical breakthroughs. However, mRNA technology is not limited to infectious diseases. Once delivered into the body, the mRNA instructs cells to produce these antigens, which are then presented to the immune system.
Published on bit.bio’s website, this article authored by Dr Tony Oosterveen dives into the close relationship between FTD and ALS with a focus on mechanisms underlying the neuropathology of both diseases. ALS is the most common motor neuron disease and is estimated to affect more than 80,000 people worldwide.
In the dynamic world of drug discovery, the notion of "undruggable" targets presents both a significant challenge and an intriguing frontier for researchers and pharmaceutical companies. Beyond Proteins: DNA and RNA Frontier The story doesn’t end with proteins.
Each week, Dr. Dylan Verden of KIF1A.ORG summarizes newly published KIF1A-related research and highlights progress in rare disease research and therapeutic development.

So we took lots of reference single-cell RNA sequencing data from atlases and used our scalable machine learning algorithms to embed all of the gene expression data on these cells into compact vector representations — you can think of these as a signature for each cell. We wanted to build a tool like that for cell biology.

It’s important to note that the 300-page report, while presenting detailed evidence for the potential harms of mirrored life, uses painstakingly speculative language. DNA and RNA molecules are also built from exclusively right-handed nucleic acids. It gives humanity time to steer away. This is one of them.
How has nucleolar stress (NS) been linked to age-related diseases, and what approach did researchers use to investigate its toxicity? The nucleolus (and nucleolar stress) had been previously linked to aging and age-related diseases such as cancer or degeneration. However, the mechanism of this observation was not fully understood.

Doctors in training are told that when they hear hoofbeats, they should think horses, not zebras; rare diseases are the exception, not the rule. Sometimes, though, novel diseases do emerge, and as COVID-19 demonstrated, they can surprise us. This is the third essay of four in our pandemic mini-issue.
5 Here, the original oncogene is still present but the transdifferentiated cancer cells are less dependent on it. Investigating non-oncogene resistance as a parallel defense mechanism used by cancer cells to evade therapies could therefore present a significant opportunity to address drug resistance more comprehensively.
