Paligenosis, Mills explains, appears similar to apoptosis — the programmed death of cells as a normal part of an organism's growth and development — in that it seems to happen the same way in every cell, regardless of its location in the body.
«Thanks to improvements in the understanding of AML biology, a multiplicity of so - called targeted therapies and therapies based on differential pathophysiology of leukemic stem cells compared with normal counterparts have emerged,» noted Richard M. Stone, MD, clinical director of the Adult Leukemia Program at Dana - Farber Cancer Institute in Boston, and colleagues, writing in a review for the ASCO 2017 Educational Book.

In embryos where the mix of normal and abnormal cells was half and half, the researchers observed that the abnormal cells within the embryo were killed off by «apoptosis», or programmed - cell death, even when placental cells retained abnormalities.
These findings suggest that cancer cells subvert key genetic programs that guide immature cells to build organs during normal growth.

New data and research approaches have created opportunities for researchers to study in detail many aspects of cancer biology, including how the normal biological programs of cell proliferation and death are altered during cancer and how the immune system responds to tumors.
NCI supports and directs research on the biological differences between normal cells and cancer cells through a variety of programs and approaches.
Because programmed cell death goes awry in leukemias and other cancers, Hu is currently examining lincRNA - EPS's function in normal and diseased human cells in an effort to determine whether it plays a role in tumor development and growth.

Anti-apoptotic proteins in cancer cells were inhibited, while normal cells» apoptotic programming was left intact.
To determine whether or not the damaging effects on cancer cells would affect normal cells — which are already programmed normally for apoptosis — they doused both cancerous liver cells and normal liver cells with CVE to examine the process of inducing apoptosis, which involves creating DNA damage as a precursor.

One of the functions of progesterone is to «turn on» the genetic programming that tells both normal and cancerous cells to die at the proper time.
It can also kill many different types of cancer cells by triggering apoptosis (programmed cell death) without affecting normal cells.
✓ Cytotoxicity — WGA has been demonstrated to be cytotoxic to both normal and cancerous cell lines, capable of inducing either cell cycle arrest or programmed cell death (apoptosis).
The virus activates growth - promoting genes in the DNA (oncogenes), at the same time it inactivates suppressor genes that would normally limit cell proliferation and alters the genes that regulate normal, programmed cell death.
