What else can I help you with?
Is BRCA1 considered an oncogene?
Yes, BRCA1 is considered a tumor suppressor gene, not an oncogene.
What is the function of a tumor suppressor gene in the human body?
Tumor suppressor genes help regulate cell growth and prevent the development of cancer by controlling cell division and repairing damaged DNA.
Is the inheritance pattern of the BRCA1 gene dominant or recessive?
The inheritance pattern of the BRCA1 gene is dominant.
Who identified the p53 gene?
The p53 gene was identified by a team of researchers led by Dr. David Lane and Dr. Arnold Levine in 1979. The protein encoded by the p53 gene plays a critical role in suppressing tumor formation and is often referred to as the "guardian of the genome."
What role does the gene labeled as "BRCA1" play in the development of breast cancer?
The gene BRCA1 helps repair damaged DNA in cells, which can prevent the growth of abnormal cells that could lead to breast cancer. Mutations in the BRCA1 gene can increase the risk of developing breast cancer because the cells may not be able to repair DNA damage properly.
Is BRCA1 considered an oncogene?
Yes, BRCA1 is considered a tumor suppressor gene, not an oncogene.
What is the function of a tumor suppressor gene in the human body?
Tumor suppressor genes help regulate cell growth and prevent the development of cancer by controlling cell division and repairing damaged DNA.
What is apc?
APC is classified as a tumor suppressor gene. Tumor suppressor genes prevent the uncontrolled growth of cells that may result in cancerous tumors. The protein made by the APC gene plays a critical role in several cellular processes that determine whether a cell may develop into a tumor.
Is the inheritance pattern of the BRCA1 gene dominant or recessive?
The inheritance pattern of the BRCA1 gene is dominant.
What are two types of genes that when disrupted can cause cancer?
The two genes considered responsible for the cause of cancer are the oncogene and the tumor suppressor gene.
What is the difference between a tumor suppressor gene and an oncogene?
Oncogenes regulate cell division, so if it is placed near an overly active gene, it may itself become overly active, thus causing cancer. Tumor suppressors suppress tumors and will only cause cancer if it stops its activity, contrary to oncogenes.
What are tumor suppressor and oncogenes genes?
Tumor suppressor genes are normal genes that carry out several functions: * slow down cell division * repair mistakes made when DNA is being replicated * tell cells when to die (a process known as apoptosis or programmed cell death) A mutation in a tumor suppressor gene allows cells to grow out of control, which can lead to cancer ie the growth of a tumor. About 30 tumor suppressor genes have been identified, including p53, BRCA1, BRCA2, APC, and RB1. A good analogy for tumor suppressor genes is the brake pedal on a car - it normally keeps the cell from dividing too quickly just as a brake keeps a car from going too fast. If the brakes on a car fail, the car goes out of control; similarly, when something goes wrong with the gene, such as a mutation, cell division can get out of control.

What is a malignant gene?
A malignant gene is a gene that has mutated and is involved in promoting cancer growth and progression. These genes can be oncogenes, which promote cell proliferation, or tumor suppressor genes, which normally inhibit cell growth but are inactivated in cancer.
Who identified the p53 gene?
The p53 gene was identified by a team of researchers led by Dr. David Lane and Dr. Arnold Levine in 1979. The protein encoded by the p53 gene plays a critical role in suppressing tumor formation and is often referred to as the "guardian of the genome."

The gene BRCA1 helps repair damaged DNA in cells, which can prevent the growth of abnormal cells that could lead to breast cancer. Mutations in the BRCA1 gene can increase the risk of developing breast cancer because the cells may not be able to repair DNA damage properly.
What is the P53 gene function?
p53 is a gene that codes for a protein (p53) that is an important tumor suppressor. Although the number of pathways and roles of p53 continue to expand it is, perhaps, most well known for slowing cell proliferation or inducing apoptosis if DNA damage or uncontrolled growth is detected.
Where can one find information about Tumor Suppressor Genese?
You can find information about Tumor Suppressor Genes in Bio Portfolio, Chips Books, Cancer Res, Academic Research Microsoft, Nature,Freezing Blue, Cancer 2000.
