Hereditary diffuse gastric cancer and lost cell polarity: a short path to cancer

Future Oncology
Bostjan Humar, Parry Guilford

Abstract

The mechanisms that underlie the initiation of human cancer are poorly understood. Here, we describe the development of hereditary diffuse gastric cancer and argue that it arises from the disruption of the regenerative processes that are inherent to all epithelial tissues. This model supports the cancer stem cell hypothesis, in which tumors contain a subpopulation of cells with the key stem cell characteristics of capacity for self renewal, differentiation and limitless replication. We argue that epigenetic modifications induced by common environmental and physiological pressures are able to initiate this disruption. The carcinogenic effects of these modifications are potentially reversible through the use of epigenetic therapies such as DNA demethylating agents and histone deacetylation inhibitors.

Cancer Epigenetics & Metabolism (Keystone)

Epigenetic changes are present and dysregulated in many cancers, including DNA methylation, non-coding RNA segments and post-translational protein modifications. The epigenetic changes may or may not provide advantages for the cancer cells. This feed focuses on the relationship between cell metabolism, epigenetics and tumor differentiation.

Cancer Epigenetics and Senescence (Keystone)

Epigenetic changes are present and dysregulated in many cancers, including DNA methylation, non-coding RNA segments and post-translational protein modifications. The epigenetic changes may be involved in regulating senescence in cancer cells. This feed captures the latest research on cancer epigenetics and senescence.

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.
