Main AI News:

In a groundbreaking development, scientists at the National Institutes of Health (NIH) have introduced an innovative artificial intelligence (AI) tool poised to revolutionize cancer treatment customization. This cutting-edge tool, detailed in a recent publication in Nature Cancer by researchers at the National Cancer Institute (NCI), harnesses the power of single-cell RNA sequencing data to forecast a patient’s response to specific cancer drugs. By scrutinizing individual cells within tumors, this AI tool offers the potential to significantly enhance the precision of drug selection for cancer patients.

Traditional methods of matching patients with drugs rely on bulk sequencing of tumor DNA and RNA, providing only an average snapshot of the tumor’s cellular composition. However, tumors are complex entities composed of diverse cell populations, each potentially responding differently to treatment. Recognizing this complexity, researchers have turned to single-cell RNA sequencing, a state-of-the-art technology offering unparalleled resolution down to the level of individual cells. By delving into the intricacies of these cellular subpopulations, scientists aim to unravel the mysteries behind treatment resistance and non-responsiveness observed in certain cancer patients.

Despite its promise, single-cell RNA sequencing remains relatively inaccessible in clinical settings due to its high cost and limited availability. Addressing this challenge, NIH researchers embarked on a pioneering study to explore the utility of transfer learning—a machine learning technique—in leveraging existing bulk RNA sequencing data to fine-tune AI models for predicting drug responses. Remarkably, this approach yielded AI models capable of accurately forecasting drug responses at the single-cell level for a wide array of cancer drugs.

In a series of comprehensive analyses, the researchers validated the effectiveness of their AI models across various cancer types and treatment scenarios. By examining data from both cell-line studies and real patient cases, they uncovered critical insights into treatment outcomes. Notably, the AI model identified instances where the presence of a single drug-resistant clone within a tumor rendered the entire treatment ineffective, highlighting the importance of personalized treatment strategies.

Looking ahead, the researchers underscored the need for broader access to single-cell RNA sequencing data to further refine the accuracy of their AI tool. Meanwhile, they have launched a dedicated research website and provided guidance on utilizing the AI model, dubbed Personalized Single-Cell Expression-based Planning for Treatments In Oncology (PERCEPTION), to empower oncologists in making informed treatment decisions.


The introduction of NIH’s AI tool, PERCEPTION, signifies a paradigm shift in cancer treatment towards personalization and precision. By harnessing the power of single-cell RNA sequencing data, oncologists can now make more informed decisions tailored to each patient’s unique tumor composition. This innovation has the potential to drive demand for single-cell sequencing technologies and propel the development of more targeted cancer therapies in the market.
