A newly identified colon cancer gene may drive the disease by making the environment in the vicinity of tumors more hospitable to them, researchers say. Why does colon cancer grow so fast? Study ...
However, once cancer begins, cancer cells undergo a process of natural selection: the few cells with new genetic changes that enhance their survival or reproduction multiply faster, and soon come to dominate the growing tumor as cells with less favorable genetic change are out-competed. [68]
Cell growth refers to an increase in the total mass of a cell, including both cytoplasmic, nuclear and organelle volume. [1] Cell growth occurs when the overall rate of cellular biosynthesis (production of biomolecules or anabolism) is greater than the overall rate of cellular degradation (the destruction of biomolecules via the proteasome, lysosome or autophagy, or catabolism).
In cancer cells, major changes in gene expression increase glucose uptake to support their rapid growth. Unlike normal cells, which produce lactate only when oxygen is low, cancer cells convert much of the glucose to lactate even in the presence of adequate oxygen. This is known as the “Warburg Effect.”
Scientists suggest the findings could one day allow doctors to use a blood test to predict how a patient’s cancer may progress. Genetic clues reveal how cancer might grow and spread – study ...
The findings raise hope for more effective treatments for pancreatic cancer, which has a poor survival rate. Shutdown of crucial gene helps world’s deadliest cancer grow rapidly – study Skip ...
Cancer cells, however, have the ability to grow without these external signals. There are multiple ways in which cancer cells can do this: by producing these signals themselves, known as autocrine signaling ; by permanently activating the signaling pathways that respond to these signals; or by destroying 'off switches' that prevents excessive ...
Nov. 2—Washington State University chemical engineers have created new technology with the potential to treat cancer faster and cheaper than before. A minifridge is able to produce cancer ...
