- 9. Dr.Carter, congratulations on this remarkable discovery. Could you explain the significance of histone genes in cancer progression?
- 10. Your research utilized a novel technology called CUTAC. Could you elaborate on how CUTAC works and why it’s groundbreaking?
“CUTAC, developed by Dr. Steven Henikoff’s lab at Fred Hutch, allows us to directly measure gene transcription activity from DNA. It focuses on small,fragmented DNA non-coding sequences were RNAPII binds,enabling a more accurate assessment of gene expression,particularly in formalin-fixed,paraffin-embedded (FFPE) samples. Thes samples are commonly stored for long-term use, but often degrade over time, leading to lower-quality gene expression data. CUTAC overcomes this limitation, providing valuable insights into gene activity even in older samples.”
Your findings revealed a strong correlation between RNAPII levels on histone genes and cancer aggressiveness. What are the implications of this discovery for cancer diagnosis and treatment?
“Our research suggests that RNAPII levels on histone genes could serve as a powerful predictive indicator of cancer aggressiveness. This opens exciting possibilities for personalized cancer treatment. By identifying the specific molecular mechanisms driving cancer aggressiveness, clinicians can tailor therapies to target these pathways, leading to more effective and targeted treatments.”
Looking ahead, what are the next steps for your research?

A groundbreaking study published in Science has unveiled a novel biomarker with the potential to revolutionize cancer diagnosis and prognosis. Researchers from Fred Hutch Cancer center and The University of Texas MD Anderson Cancer Center discovered that the levels of RNA Polymerase II (RNAPII) on histone genes can accurately predict the aggressiveness and recurrence of meningioma brain tumors and breast cancers.
Understanding the Importance of Histone Genes
Histone genes, responsible for providing structural support to DNA within chromosomes, have long been the focus of genetic studies. However, their role in cancer progression has remained largely unexplored. Current RNA sequencing methods are unable to detect histone RNAs due to their unique structure, leading to a vast underestimation of their presence in tumor samples. This new research sheds light on the crucial role that histone genes play in cancer development.
This groundbreaking discovery was made possible by a new technology called Cleavage Under Targeted accessible Chromatin (CUTAC), developed by Dr. Steven Henikoff’s lab at Fred Hutch. CUTAC enables researchers to directly measure gene transcription activity from DNA by focusing on small, fragmented DNA non-coding sequences where RNAPII binds. This innovative approach allows for a more accurate assessment of gene expression, particularly in formalin-fixed, paraffin-embedded (FFPE) samples, which are commonly stored for long-term use but frequently enough degrade over time, leading to lower-quality gene expression data.
RNAPII Levels: A Powerful Predictive Indicator
Using CUTAC technology, the research team analyzed 36 FFPE samples from patients with meningioma. By integrating this data with nearly 1,300 publicly available clinical data samples, they discovered a strong correlation between RNAPII enzyme signals on histone genes and cancer aggressiveness.
“The technique we developed to examine preserved tumor samples now reveals a previously overlooked mechanism of cancer aggressiveness,” states Dr. Henikoff,Howard Hughes Medical Institute investigator. “Identifying this mechanism suggests it could be a new test to diagnose cancers and possibly treat them.”
“It has been overlooked that histone genes could be a rate-limiting factor in cell replication and,in turn,a strong indicator of tumor cell over-proliferation.This is because current RNA sequencing methods are unable to detect histone RNAs due to their unique structure, meaning these libraries have vastly underestimated their presence. Our novel approach, combining a new experimental technology and computational pipeline, establishes a thorough ecosystem that can leverage biopsy samples from multiple cancer types to enhance tumor diagnosis and prognosis,” explains Dr. Ye Zheng, co-first author and assistant professor of Bioinformatics and computational Biology at MD Anderson.
Looking Ahead: Expanding applications and Impact
This discovery holds immense promise for the future of cancer care. The researchers plan to expand their research by utilizing CUTAC technology on FFPE samples from various cancer types to further validate the predictive power of RNAPII expression on histone genes.
this research paves the way for the development of personalized cancer treatment strategies based on a patient’s unique tumor profile.By identifying the specific molecular mechanisms driving cancer aggressiveness, clinicians can tailor therapies to target these pathways, leading to more effective and targeted treatments.
