Breakthrough Discovery Unveils New Gene Therapy Target for Acute Myeloid Leukaemia”

In a groundbreaking exploration led by Dr Jan-Henning Klusmann and Dr Dirk Heckl at Goethe University Frankfurt, researchers revealed a potential game-changer in paediatric oncology by uncovering vital insights into the DNA of leukaemia cells.

Leukaemia encompasses various forms of blood cancer, among which acute myeloid leukaemia (AML) specifically impacts the degeneration of early-stage blood cells, posing a substantial challenge in pediatric oncology. The team’s profound discovery in AML cells presents a beacon of hope for gene therapy targeting this malignancy.

The focus centred on noncoding RNAs, a group of nucleic acids synthesized through gene transcription. Unlike messenger RNAs (mRNAs) primarily engaged in protein translation, noncoding RNAs assume regulatory roles in cell growth and division, making them pivotal in understanding cancer dynamics.

Examining the role of noncoding RNAs in AML cells, the scientists meticulously compared their pattern in cancerous cells from afflicted children with that of healthy blood stem cells. The study revealed nearly 500 distinct noncoding RNAs differentially expressed in AML cells, hinting at their critical involvement in cancerous mechanisms.

One gene, MYNRL15, stood out prominently. Disabling this gene demonstrated a significant impact, halting the indefinite replication ability of cancer cells, subsequently leading to their demise. However, the absence of noncoding RNAs alone wasn’t responsible for this effect; it was the gene itself wielding regulatory influence.

The researchers elucidated that MYNRL15 gene manipulation triggered a pivotal shift in the chromatin’s spatial organization, altering the genome’s 3D structure. This resulted in the deactivation of vital genes crucial for AML cell survival, unlocking a promising avenue in combating leukaemia.

Notably, this inhibitory effect was consistently observed across diverse AML cell lines originating from both children and adults, encompassing various disease subtypes, including those prevalent in individuals with Down syndrome. Dr. Klusmann highlighted the gene’s indispensability across all the studied leukaemia types.

This dependency on the MYNRL15 gene locus among different AML subtypes holds promising prospects for tailored gene therapies. Dr. Klusmann emphasized the potential of this discovery in charting a new course for future therapeutic interventions against AML.

The systematic investigation into noncoding RNAs and their gene interplay in AML cells offers a pioneering pathway towards targeted gene therapies, propelling hope for enhanced treatments in the battle against leukaemia. This study was published in iScience.
