New model to find treatments for an aggressive blood cancer

Cellular work has found mutation in gene that leads to disease progression in myelodysplastic syndromes (MDS)

2025-07-03
(Press-News.org) Researchers working on an incurable blood cancer can now use a new lab model which could make testing potential new treatments and diagnostics easier and quicker, new research has found.

 

In a paper published in Nature Communications a team of researchers led from the University of Birmingham have studied blood cells from patients with a blood cancer called myelodysplastic syndrome disease (MDS). This disease often develops into a highly aggressive form of Acute Myeloid Leukaemia (AML).

 

Working with this new model has led to confirmation that a mutation in the gene CEBPA causes progression from MDS to AML.

 

Dr Paloma Garcia from the University of Birmingham and lead author of the study said:

 

“Our study using blood cancer cells from a patient with MDS before and after disease progression presents two exciting developments for a better understanding of the condition.

 

“Firstly, we developed a powerful and true to life model for future research using induced pluripotent stem cells (iPSCs) from an actual patient which presents an exciting future for studying blood cancers as we are also able to recreate the mutations that led to the cancer.

 

“Secondly, the confirmation that the mutation of the CEBPA gene plays such an important role in disease progression presents a significant step towards new ways to treat and diagnose MDS and avoid more serious conditions.”

 

“I believe that our new cell culture model could form the basis of elaborate drug screening experiments which could help to find potential treatments for what currently is a highly aggressive blood cancer.”

 

 

Behaved just like patient’s real cells  

The team set out to examine whether changes to the gene CEBPA were driving disease progression in patients with MDS, or whether mutations were a passenger as the blood cancer developed into the more serious AML.

 

The team took blood cells from a patient that was diagnosed with MDS and reprogrammed these cells into iPSCs using a genetic trick. Once obtained, these cells can give rise to any cell type of the body. They then used sophisticated cell culture methods to convert them into white blood cells and red blood cells in the lab. Using multiple tests, they showed that the lab-grown cells behaved just like the patient’s real cells.

 

Using patient cells that were obtained early during disease progression without the mutation, the researchers were then able to modify the cells’ genome to include the mutation in CEBPA gene as it happened in the patient two years after being diagnosed with MDS.  This change made the disease more aggressive: it reduced the number of healthy cells, blocked the formation of white blood cells, aberrant cells were formed that divide more rapidly, even when they were treated with chemotherapy, mimicking what happened to the patient.

 

Prof Constanze Bonifer, a Birmingham Emeritus Professor and one of the Senior Authors on the paper said:

 

“To show that this was true, we did not only study the behaviour of the in vitro generated cells but also looked at how every gene in the cell population changed its activity. The experiments revealed that adding the CEBPA mutation to the mix of mutations that were already there alters how DNA is organised in blood cells, which completely changed gene activity and pushed the cells on the path to malignancy. “

 

Dr Paloma Garcia lead author of the study said: “Using iPSC cells to model disease processes  is a new and exciting way of understanding how blood cancers develop and will significantly expedite our ability to find novel treatments.”

 

The research group is open to collaboration, licensing, or partnering opportunities.

T cells take aim at Chikungunya virus

2025-07-03
LA JOLLA, CA—A new study, published recently in Nature Communications, offers the first-ever map of which parts of Chikungunya virus trigger the strongest response from the body's T cells.  With this map in hand, researchers are closer to developing Chikungunya vaccines or therapies that harness T cells to strike specific targets, or "epitopes," to halt infection. The new study also offers important clues for understanding why many people experience chronic, severe joint pain for years after clearing the virus. "Now we can see what T cells are seeing patients with chronic disease," says LJI Assistant Professor ...

Gantangqing site in southwest China yields 300,000-year-old wooden tools

2025-07-03
  New discoveries from the Pleistocene-age Gantangqing site in southwestern China reveal a diverse collection of wooden tools dated from ~361,000 to 250,000 years ago, marking the earliest known evidence of complex wooden tool technology in East Asia. The findings reveal that the Middle Pleistocene humans who used these tools crafted the wooden implements not for hunting, but for digging and processing plants. Although early humans have worked with wood for over a million years, wooden artifacts are quite rare in the archaeological ...

Forests can’t keep up: Adaptation will lag behind climate change

2025-07-03
Ecologists are concerned that forest ecosystems will not keep pace with a rapidly changing climate, failing to remain healthy and productive. Before the rapid climate change of the past century, tree populations in the Northern Hemisphere adapted to colder and warmer periods over thousands of years. During onsets of Ice Ages, tree populations migrated south, seeking warmer conditions as global temperatures cooled, their seeds dispersed by winds and carried by animals. When the climate warmed again, tree species adapted by migrating north to more suitable conditions. Mature trees are long-lived, and their populations can’t migrate quickly. Current climate change ...

Sturgeon reintroduction initiative yields promising first-year survival rate

2025-07-03
Ecologists celebrated the release of thousands of palm-sized lake sturgeon into northwest Ohio's Maumee River in 2018, kicking off an ambitious two-decade plan to re-establish the ancient species in the waters it once called home. More than five years later, it’s still too soon to declare success. But early signs are promising, according to recent research led by The University of Toledo and published in the peer-reviewed North American Journal of Fisheries Management. The research tracked the first-year survival rates for cohorts released in 2018, 2019 and 2021, with results suggesting that the initiative is on track to achieve its goal of a self-sustaining ...

Study: Babies’ poor vision may help organize visual brain pathways

2025-07-03
CAMBRIDGE, MA -- Incoming information from the retina is channeled into two pathways in the brain’s visual system: one that’s responsible for processing color and fine spatial detail, and another that’s involved in spatial localization and detecting high temporal frequencies. A new study from MIT provides an account for how these two pathways may be shaped by developmental factors. Newborns typically have poor visual acuity and poor color vision because their retinal cone cells are not well-developed at birth. This means that early in life, they are seeing blurry, color-reduced imagery. The MIT team proposes that such blurry, color-limited ...

Research reveals Arctic region was permafrost-free when global temperatures were 4.5˚ C higher than today

2025-07-03
Scientists have found evidence that the Asian continent was free of permafrost all the way to its northerly coast with the Arctic Ocean when Earth’s average temperature was 4.5˚C warmer than today, suggesting that the whole Northern Hemisphere would have also been free of permafrost at the time. The stark findings indicate that if average global temperatures were to rise by this amount in the future, permafrost found in the Northern Hemisphere today would thaw. Such a temperature increase would release up to 130 billion tonnes of carbon currently frozen in the ground over the coming decades. The ...

A breakthrough in motor safety: AI-powered warning system enhances capability to uncover hidden winding faults

2025-07-03
Enhanced diagnostic method of the ITSC fault The study, led by Dr. Wentao Huang, overcame a critical gap in five-phase permanent magnet synchronous motor (PMSM) diagnostics: conventional methods fail to assess inter-turn short-circuit (ITSC) severity. The method integrates two technologies: a real-time tracker that diagnoses faults, and an AI analyzer that processes signals to quantify damage while estimating short-circuit parameters. Overcoming the Blind Spot For years, the challenge of quantifying inter-turn short-circuit severity in operating motors has stumped engineers, as traditional methods struggled ...

Research teases apart competing transcription organization models

2025-07-03
Scientists at St. Jude Children’s Research Hospital have reconciled two closely related but contentious mechanisms underlying transcription, the process of converting genetic information in DNA into messenger RNA. Phase separation has been proposed as a driving force in transcription due to its ability to selectively concentrate proteins and DNA in discrete droplets. However, scientists have been unclear about what really matters for transcription: the phase-separated droplets or the molecular interactions that contribute to phase separation by forming networks.     To address ...
