Special Issue Information

Dear Colleagues,

The physics of cancer represent an interdisciplinary research area investigating how mechanical forces and changes in the physical properties of cancer cells and their environment favor the progression of cancer. The field of cancer physics incorporates principles from biology, physiology, physics, engineering, and material science to understand how mechanical signals in cancer are sensed, transmitted, and integrated into biological processes, leading to malignant progression. The field of the physics of cancer is currently at a critical crossroads, with the potential to develop from a purely research-orientated field into a field with practical applications in cancer diagnosis and cancer therapy. The high stiffness of solid tumors and high interstitial pressure with hypoxia and acidosis represent a research focus in the physics of cancer, as they directly induce the mechanical activation of biochemical signaling pathways that promote the cell cycle, epithelial–mesenchymal transition, and cell motility/invasiveness. The aggressiveness of cancer is correlated with increased deformability in cancer cells, which may also control the ability of cancer cells to engulf other cells during tumor microevolution or to absorb drugs and thus respond to therapy. These findings revolve around the ability of cells to sense forces and physically explore their surroundings (mechanosensing) and to pass this message on to the cell nucleus (mechanotransduction). The intricacies of cellular mechanotransduction are far from being completely elucidated, but it has been proposed that specific transcription factors and membrane receptors play a central role.

Besides genomic and proteomic analyses of bulk and individual cancer cells, cancer research focuses on the mechanical analysis of cancers, such as cancer cells. Throughout the oncogenic evolution of cancer, mechanical inputs are stored as epigenetic memory, which ensures versatile coding of malignant characteristics and a quicker response to external environmental influences in comparison to solely mutation-based clonal evolutionary mechanisms. Cancer’s mechanical memory is a proposed mechanism for how complex details such as metastatic phenotypes, treatment resistance, and the interaction of cancers with their environment could be stored at multiple levels. The mechanism appears to be similar to the formation of memories in the brain and immune system like epigenetic alterations in individual cells and scattered state changes in groups of cells. Carcinogenesis could therefore be the outcome of physiological multistage feedback mechanisms triggered by specific heritable oncogenic alterations, resulting in a tumor-specific disruption of the integration of the target site/tissue into the overall organism. This review highlights and discusses the impact of the ECM on cancer cells’ mechanical memory during their metastatic spread. Additionally, it demonstrates how the emergence of a mechanical memory of cancer can give rise to new degrees of individuality within the host organism, and a connection to the cancer entity is established by discussing a connection to the metastasis cascade. The aim is to identify common mechanical memory mechanisms of different types of cancer. Finally, it is emphasized that efforts to identify the malignant potency of tumors should go way beyond sequencing approaches and include a functional diagnosis of cancer physiology and a dynamic mechanical assessment of cancer cells.
