Cancer associated fibroblasts in cancer development and therapy

Area of Science:

• Oncology
• Cancer Biology
• Tumor Microenvironment Research

Background:

• Cancer-associated fibroblasts (CAFs) play multifaceted roles in cancer development and therapy.
• CAFs, originating from diverse cell types, transform upon interaction with tumor cells, impacting cancer severity and treatment outcomes.
• Single-cell RNA sequencing (scRNA-seq) reveals significant heterogeneity and plasticity in CAFs, with distinct subtypes identified by gene expression and function.

Purpose of the Study:

• To review fundamental knowledge and recent advances on CAFs' roles in cancer development.
• To explore CAFs as potential therapeutic targets.
• To discuss strategies for targeting CAFs to improve cancer treatment efficacy.

Main Methods:

• Literature review summarizing current understanding of CAFs.
• Analysis of scRNA-seq data to identify CAF heterogeneity and subtypes.
• Discussion of various therapeutic strategies targeting CAFs and their interactions within the TME.

Main Results:

• CAFs promote cancer development via ECM remodeling, metabolic support, epithelial-mesenchymal transition (EMT), and cancer stem cell properties.
• CAFs contribute to an immunosuppressive TME and therapeutic resistance.
• CAF heterogeneity suggests context-specific roles in cancer progression.

Conclusions:

• Understanding the complex interplay between CAFs and the TME is essential for developing novel targeted cancer therapies.
• Targeting CAFs through ECM modulation, direct elimination, crosstalk interruption, or normalization presents viable therapeutic approaches.
• Further research into CAF subtypes and their specific functions will refine targeted treatment strategies.
