Cancer stemness

Dying cancer cells release the chemical potassium, which can reach high levels in some tumors. The research team reported that elevated potassium causes T cells to maintain a stem-cell-like quality, or stemness, that is closely tied to their ability to eliminate cancer during immunotherapy. Cancer stem cell - The cancer stem cell model. Our indices derived from mRNA expression and DNA methylation signatures reliably stratified tumors of known stemness phenotype.

The cancer stem cell model, also known as the Hierarchical Model proposes that tumors are hierarchically organized (CSCs lying at the apex (Fig. We report that when considering solid cancer types, immune cell exclusion is widely associated with the presence of a stem cell-like phenotype in tumors (stemness). While adult Stem Cells display these properties when participating in tissue homeostasis, Cancer Stem Cells (CSCs) behave as their malignant equivalents. Experimental evidence indicates that a subpopulation of cancer cells, called cancer stem cells (CSCs possess stemness properties similar to normal stem cells, including self-renewal, differentiation, and proliferative potential).

Cancer stemness also appeared to involve core expression of MYC, OCT SOX and other genes involved in the regulatory circuitry that underlies normal and malignant self-renewal potential. Apr 3 20The exclusion of immune cells from the tumor microenvironment has been associated with poor prognosis in the majority of cancers.

Harnessing T-cell stemness could enhance cancer

We found pervasive negative associations between cancer stemness and anticancer immunity. Cancer therapy: Defining stemness Nature Jun 0 20Enter Lucie Laplane and her book Cancer Stem ained as a science philosopher, Laplane also spent time at the bench in two stem-cell labs. May 1 20Conclusions: Our data establish a mechanism of chemotherapy-induced cancer stemness by linking the cellular events in the bone marrow and tumors, and suggest pharmacologic inhibition of CCRas a potential cotreatment during conventional chemotherapy in neoadjuvant and adjuvant settings. 3).) Within the cancer population of the tumors there are cancer stem cells (CSC) that are tumorigenic cells and are biologically distinct from other subpopulations They have two defining features: their long-term ability. Apr 3 20Using gene-expression-based metrics, we evaluated the association of stemness with immune cell infiltration and genomic, transcriptomic, and clinical parameters across solid cancers.

Stemness combines the ability of a cell to perpetuate its lineage, to give rise to differentiated cells, and to interact with its environment to maintain a balance between quiescence, proliferation, and regeneration. A normal vagina discharge is clear, white or off-white in color.
