Malignant cells in general?
Malignant cells are cell that are not in use at the current time.
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.
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.
How do human cells die?
by apoptosis and necrosis
How have Malignant cells changed?
Malignant cells have changed such that they lose normal control mechanisms governing growth
What does negative malignant cells mean?
A malignant cell is a cancer cell. Once that is growing out of control. No malignant cell means the absence of cancer cells. This means the observed cells are healthy.
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 malignant transformation?
Malignant transformation is the process by which normal cells undergo changes that lead to uncontrolled growth and the potential to invade surrounding tissues, resulting in cancer. This transformation is often driven by genetic mutations, environmental factors, or a combination of both, which disrupt normal regulatory mechanisms of cell division and apoptosis. As a result, these transformed cells can proliferate uncontrollably and develop the ability to spread to other parts of the body, forming tumors.
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).
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.
