Contrast apoptosis and cancer?
Apoptosis is a programmed cell death process that occurs in healthy cells to maintain tissue homeostasis, while cancer is the uncontrolled proliferation of cells due to genetic mutations. Apoptosis can help eliminate damaged or unwanted cells, while cancer cells evade apoptosis, leading to tumor development. Understanding the balance between apoptosis and cell proliferation is essential in cancer research and therapy.
A class of lipids used to signal cells to undergo changes is called?
The class of lipids used to signal cells to undergo changes is called phospholipids. These molecules play a key role in cell signaling, as they can affect cellular processes such as growth, differentiation, and apoptosis.
Explain how apoptosis can prevent abnormal cells from becoming tumors?
Apoptosis might be seen as part of the body's overseeing/managing/protecting mechanism. Apoptosis is associated with cell death; a programmed cell death, where "abnormal" cells, which either cannot function properly (aged, injured, etc), or are potential threat to the organism (infected, mutated), have to die. By activating apoptosis of those cells, the body stops their proliferation. If this mechanism gets impaired (for example tumour suppressor genes, like p53, cannot promote apoptosis), the uncontrolled proliferation of the abnormal cells could lead to malignancy.
Why dont cancer cells undergo apoptosis?
In cancerous cells, the normal programming to undergo apoptosis may not be activated due to the nonreception of proapoptotic signals, the decrease or lack of synthesis of proapoptotic signals, the increase in the synthesis of antiapoptotic signals, or a combination of all of these.
What is a sentence for apoptosis?
Apoptosis is a programmed cell death process that plays a crucial role in maintaining tissue homeostasis and eliminating damaged or unwanted cells. For example, during embryonic development, apoptosis helps shape organs by removing excess cells. This natural mechanism is essential for preventing cancer and other diseases by ensuring that malfunctioning cells are efficiently disposed of.
Is apoptosis a feature of malignant cells?
No, that's the opposite, most malignant cells have lost their ability to undergo apoptosis.

How do human cells die?
by apoptosis and necrosis
What might happen if apoptosis did not occur in cells that have significant DNA damage?
If apoptosis did not occur in cells with significant DNA damage, these cells could potentially undergo uncontrolled division and give rise to cancerous tumors. Apoptosis is a natural process that helps prevent the proliferation of damaged cells, so its absence could lead to the survival of mutated cells that may pose a threat to the organism's health.
What is the annexin V staining protocol for detecting apoptosis in cells?
The annexin V staining protocol is a method used to detect apoptosis in cells. It involves labeling cells with annexin V, a protein that binds to phosphatidylserine on the outer membrane of apoptotic cells. This allows for the identification of cells undergoing apoptosis by using fluorescence microscopy or flow cytometry.
What is Apoptosis and what role does it play?
Apoptosis is when cells destroy themselves. This is done for two main reasons:To destroy cells which are a risk to the organism, such as cells with viruses.It is important in normal development, such as shedding the lining of the uterus (menstruation).

Scientists think cancer begins when?
Scientists actually believe that cancerous cells are constantly forming in our bodies. However, under normal circumstances, these cells either die on their own, usually through a process called apoptosis, or are cleared by our immune systems. These cancerous cells form as a result of epigenetic or genetic changes within the cell. If these changes result in the cells being resistant to apoptosis and our immune systems, tumors begin to form.

What is the term meaning programmed cell death?
Cells are programmed to respond to specific combinations of molecules and without these molecules. Without these molecules to signal they will go through apoptosis or programmed cell death. It is the reason we have separate fingers and toes. Apoptosis is the natural part of growth and remodeling that involves the process of programmed cell death.
