At the cellular level, mad cow disease (BSE or bovine spongiform encephalopathy) is caused by a mis-folded protein that causes other copies of the same protein to mis-fold as well. These mis-folded proteins (called prions) do not function and cannot be broken down by the cell, so they accumulate like so much cellular junk in the cytoplasm until the cell dies from inability to function. The clinical signs at the whole animal level are caused by the deaths of nerve cells.
In contrast, at the cellular level cancer is caused by one or more genetic mutations that cause the cell to divide rapidly and disregard the normal intercellular signals to stop dividing. While there are sometimes significant abnormalities in protein production and function, these are a side effect of the cancer rather than the underlying cause.
What else can I help you with?
What is an example of cellular level?
An example of the cellular level is the mitochondria within a cell. Mitochondria are vital organelles that produce energy for the cell through cellular respiration. They have their own DNA and are essential for various cellular functions.
How does the disease affect each the following levels of organization argan?
To provide a specific response, I would need to know which disease you are referring to, as the effects can vary widely depending on the condition. Generally, diseases can impact levels of biological organization such as cells, tissues, organs, and systems. For example, a disease might cause cellular damage at the cellular level, leading to tissue dysfunction, which can impair organ function and ultimately affect the entire organ system. If you specify the disease, I can give a more tailored answer.
What is respiration from the organ level to the cellular level?
At the organ level, respiration involves the exchange of gases (oxygen and carbon dioxide) in the lungs. At the cellular level, respiration refers to the metabolic process where cells generate energy by breaking down nutrients with the help of oxygen. This cellular respiration occurs in the mitochondria and produces adenosine triphosphate (ATP) as energy currency for the cell.
Why does an oncologist need to study biology and chemistry?
An oncologist studies biology to understand how cancer develops in the body and spreads. Knowledge of chemistry is important for understanding how cancer treatments such as chemotherapy work on a cellular level, as well as for understanding the chemical pathways involved in cancer development and treatment.
How are cytologists important?
Are you kidding me? Cytology is a branch of biology that deals with the formation, structure, and function of cells. Without being able to understand cells or cellular function we would never find a cure to cellular diseases, such as cancer. Cytologists work closely with pathologists using microscopic evaluation to detect changes in bodily cellular material. Physicians can then use the information supplied by the cytologist to make a diagnosis. They can also help diagnose very early stages of cancer, giving the patient a better chance for survival.
What is the difference between molecular remission and cellular remission?
Molecular remission refers to the absence of detectable disease at the molecular level, such as minimal residual disease in leukemia, which may still be present at the cellular level. Cellular remission, on the other hand, typically refers to the absence of disease or cancer cells in the body, as determined by tests like bone marrow biopsy.
What's the difference of a level 4 colon cancer from level 4 rectal cancer?
The severity(spread of cancer) of the disease is same at stage 4, no matter if it is large intestine or rectal cancer.
What is the significance of vitamin B12 level of 1427?
A vitamin B12 level of 1427 is high. It could be indicative of an illness such as liver disease, kidney disease, or cancer.
Increased levels of what indicate prostatic disease or cancer?
An increased level of PSA (Prostate Specific Antigen) may indicate the presence of disease.
What is histopathalogy?
Histopathology is the study of tissues at a microscopic level to diagnose disease. It involves examining small sections of tissue from biopsies or surgical specimens under a microscope to identify cellular changes indicative of disease processes. Histopathology is essential in determining the nature and extent of diseases such as cancer.
When Point mutation occurrs at a cellular level what diseases can be caused?
When point mutation occurs at cellular level, it can cause many diseases. Some of these diseases include Cancer, Sickle-Cell Anemia, Cystic Fibrosis and Color Blindness.
How can the CEA level in a patient be temporarily increased?
Certain types of cancer treatments, such as hormone therapy for breast cancer, may actually cause the CEA level to go up. This elevation does not accurately reflect the state of the disease.
What is PET scan used for?
PET scans are most commonly used to detect cancer, heart problems ( such as coronary artery disease and damage to the heart following a heart attack!
What level of organization are missing in sponges?
sponges have cellular level organisation meaning that their cells are specialized so that different cells perform different functions
What are the different types of Niemann-Pick disease related to?
The different types seem to be related to the activity level of the enzyme sphingomyelinase.
What diseases other than cancer produce increased CEA levels?
Some noncancerous diseases, such as hepatitis, inflammatory bowel disease, pancreatitis, and obstructive pulmonary disease, may cause an elevated CEA level.
What is the structure above the cellular level called?
The structure above the cellular level is called a tissue. Tissues are groups of cells that work together to perform a specific function in the body. They can be classified into different types such as epithelial, connective, muscle, and nervous tissues.
