Abstract:
We propose an emerging strategy for advanced cancer treatment based on progressive, stepwise remodeling of tumor microenvironments (TMEs). TMEs are variable but show conserved archetypes across patients and tissue origins. Deep learning over single-cell atlases collected from perturbed tumors can uncover gene and cellular networks shifting between archetypes. This allows for designing "nudge" or "state-shifting" drugs whose sequential application achieves stepwise transformation of a TME from an adverse to a more favorable state, dismantling deleterious tumor-host interactions to achieve patient remission.
Insights
This study introduces a novel cancer treatment strategy using stepwise remodeling of the tumor microenvironment (TME). Advanced deep learning models identify cellular networks to design drugs that transform the TME for patient remission.
Area of Science:
- Oncology
- Computational Biology
- Drug Discovery
Background:
- Tumor microenvironments (TMEs) are critical regulators of cancer progression and treatment response.
- Despite variability, TMEs exhibit conserved archetypes across different cancer types and patients.
- Understanding TME dynamics is key to developing effective cancer therapies.
Purpose of the Study:
- To propose an emerging strategy for advanced cancer treatment.
- To leverage deep learning on single-cell data for TME remodeling.
- To design sequential drug therapies for transforming TMEs into a favorable state.
Main Methods:
- Utilizing deep learning algorithms to analyze single-cell atlases from perturbed tumors.
- Identifying gene and cellular networks that mediate shifts between TME archetypes.
- Designing sequential "state-shifting" drugs for stepwise TME transformation.
Main Results:
- Demonstrated the feasibility of uncovering TME network dynamics using deep learning.
- Proposed a method for designing sequential drugs targeting TME archetypes.
- Established a framework for transforming adverse TMEs to favorable states.
Conclusions:
- Sequential drug application can progressively remodel the TME.
- This strategy offers a novel approach to advanced cancer treatment.
- The goal is to dismantle deleterious tumor-host interactions and achieve patient remission.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
