Why is cell differentiation important in multicellular organisms? Why does a cell undergo mitosis? Why are there no chloroplasts in onion cells? Why do erythrocytes always use anaerobic instead of aerobic glycolysis? Why is mitochondria impermeable to oxaloacetate?
Why is the relationship between the function of the cell and the function of the body so important? Provide some medical examples. Why does osteoarthritis occur? Explain your reasons. What distinguishes cancer cells from the cells of benign neoplasms?
Autophagy promotes necrosis in apoptosis-deficient cells in response to ER stress Cell death and differentiation is a monthly research journal focused on the exciting field of programmed cell death and apoptosis. It provides a single acc... E Ullman,Y Fan,M Stawowczyk,... - 《Cell Death &...
or programmed cell death.Loss of apoptosisrefers to the “immortality” typical of cancer cells. Normal body cells are programmed to die off when appropriate.130Cancer cells have lost this ability (often as a result of DNA damage), which allows them to reproduce essentially without ...
Cultured melanoma cells can synthesize calcitriol from 25(OH)D and express the VDR. Moreover, 1,25(OH)D has anti-proliferative and pro-differentiation effects in human melanoma cells. 1,25(OH)D has been shown to induce apoptosis in human melanoma cell lines and has an inhibitory effect on...

However, there is more than one possibility, and ifthere is a tumor growing, knowing its origin and whether it is benign or cancerous is very important. The diagnosis can not be done just by looking at it. Even an experienced vet will need to perform additional tests to know exactly what...
The lncRNA field is in its infancy yet from what we do know we find that lncRNAs play critical roles in a wide variety of biological processes and diseases from cell differentiation, tissue organ development, flowering in plants, to cancer metastasis to name just a few [[26], [27], [28...
Whether investigators choose to consider any spotting as day 1 or onset of full flow as day 1 varies, but should remain consistent within a given study. well (Gregg et al, 2010). Within the neuroendocrine hypo- thalamus, this study showed that there was an important interaction at the ...
The ability to give rise to differentiated progeny of different specialized subtypes. However, some self-renewing cells (for example, pancreatic β-cells) have a narrow potential for differentiation, generating progeny similar to the parental cell. This type of self-renewing cell is termed a 'unipo...
