Summary Introduction
Introduction:
Apoptosis is the programmed cell death mechanism used to eliminate aged, mutated, unwanted, or uncontrolled cells in the multicellular organisms. Caspase (cysteine protease) proteins play a crucial role in mediating the apoptotic mechanism. The morphological features of apoptosis undergoing cells are membrane blebbing, shrinkage of cells, chromatin condensation, nuclear fragmentation, and formation of apoptotic bodies. Macrophages engulf these apoptotic bodies and thereby this mechanism prevents necrosis (accidental cell death) and inflammation.

Question 20
According to many previous studies, stiffness of the pancreatic cancer cells is associated with increased invasive potential. Increased invasive potential means that the cancer cells are more likely to escape from the
primary tumor and travel to other parts of the body.
If you want to study the stiffness of the individual cells (assuming that the cells are not attached to each other),
(1) what method would you want to use? And briefly explain why you choose this one.
(2) briefly explain how the experiments should be carried out to measure the cell stiffness;
(3) briefly discuss what data this experiment would generate;
(4) briefly discuss how you would draw conclusions from the acquired data mentioned above.
CE ALT+F10 (PC) or ALT+FN+F10 (Mac).

TRUE OR FALSE
1. Since a tattoo is a pigment considered as an intracellular accumulation, it is absolutely toxic
2. Even if the cell is intact, there can be an irreversible cell injury if the nucleus is affected
3. There is excessive accumulation of substances in a tissue if you will not only be able to observe them intracellularly but also extracellularly
I’m so confused on all these.

- What is the difference between a proto-oncogene and an oncogene? Group of answer choices 1. These are two categories of genes. Proto-oncogenes are genes that fight cancer, oncogenes are genes that cause cancer. 2. Proto-oncogenes are naturally occurring genes in the human genome, while oncogenes come from viruses that cause cancer. 3. These are alleles of the same gene. Proto-oncogenes are wildtype alleles, and oncogenes are cancer-causing alleles.arrow_forwardQUESTION: A 35-year-old man is known to have been HIV-positive for the past 10 years.
