Epigenetics: Biologists discover 71 new “imprinted” genes in the mouse genome

Researchers: Scientists have yet to work out how one parental version of a given gene can be switched (or faded) on or off and maintained that way while the other is in the opposite state. It is known that much of the on/off switching occurs during the formation of gametes (sperm and egg), but the precise mechanisms remain unclear. This new study points to the intriguing possibility that some imprinted genes may not be marked in gametes, but become active later in development, or even in adulthood.

How, exactly, do damaged or diseased cells “commit suicide” to protect the body?

Why this matters: Cancer cells avoid destruction by inhibiting a process (which is called necroptosis). And necroptosis happening when it shouldn’t “is linked to the damage from multiple sclerosis, Parkinson’s disease and tissue injury from blood flow loss.” Targeting these processes could be an avenue for treatment.

Researchers: A kill cancer code is embedded in every cell

From ScienceDaily: A kill code is embedded in every cell in the body whose function may be to cause the self-destruction of cells that become cancerous, reports a new Northwestern Medicine study. As soon as the cell’s inner bodyguards sense it is mutating into cancer, they punch in the kill code to extinguish the mutating Read More…

Cell behaviour can show “purposeful inefficiency”? What next?

We thought “purposeful efficiency” was enough to get a researcher fired, but read on: From ScienceDaily: The steps cells take in response to challenges are more complex than previously thought, finds new research published in the journal eLIFE. The study investigates a system relevant to cancer, viral infection, and diabetes as well as Parkinson’s and Read More…

Do cells use passwords?

Sloan Kettering molecular biologist argues that this may not be semantics. What if that’s what they are actually doing, in effect? One wonders, how would it affect cancer treatment? Abstract: Living organisms must maintain proper regulation including defense and healing. Life-threatening problems may be caused by pathogens or an organism’s own cells’ deficiency or hyperactivity, in Read More…
