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 effect does oncogenes have on cells?
Cells with an oncogene become over-stimulated to divide more often than normal. The chances of cancer developing are increased if a mutation to a tumor-suppressor gene also occurs. As an oncogene is a cancer-causing gene
An oncogene is?
An oncogene is a gene that has the potential to cause cancer. They can promote cell growth or prevent normal cell death, leading to uncontrolled cell division and tumor formation. Mutations in oncogenes can contribute to the development of cancer.
What are oncogenes and how do they affect the cell cycle?
The region of the viral genome (DNA in DNA tumor-viruses or RNA in RNA-tumor viruses) that can cause a tumor is called an oncogene. This foreign gene can be carried into a cell by the virus and cause the host cell to take on new properties such as immortalization and anchorage-independent growth.
What is p53 marker?
p53 is a protein that acts as a tumor suppressor, helping to prevent the formation of cancerous tumors. It is often used as a marker for cancer because mutations in the p53 gene are commonly found in various types of cancer cells. Detection of p53 abnormalities can help with cancer diagnosis and prognosis.
Is BRCA1 considered an oncogene?
Yes, BRCA1 is considered a tumor suppressor gene, not an oncogene.
When was Oncogene - journal - created?
Oncogene was first published as a journal in 1987. It covers research related to oncogenes, tumor suppressor genes, and cancer cell biology.
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.
Is BRCA1 a tumor suppressor gene?
Yes, BRCA1 is a tumor suppressor gene.
What is pro- oncogene?
An oncogene is a gene, when mutated or expressed at high levels it helps turn a normal cell into a tumor cell.
What is the p35 cancer gene?
tumor suppresser gene that could turn into 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 effect does oncogenes have on cells?
Cells with an oncogene become over-stimulated to divide more often than normal. The chances of cancer developing are increased if a mutation to a tumor-suppressor gene also occurs. As an oncogene is a cancer-causing gene
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.
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.
Explain how mutations in tumor suppressor genes can contribute to cancer?
Well, tumor suppressor genes are basically proteins that regulate the eradication of cells that develop mutations in the G1 or G2 phase of the cell cycle. For example, lets say a 54 year old patient has the Trp53 tumor suppressor protein mutation. What this means is that this patient has less of an ability to sense cells with mutations in the pancreas because they are deficient or void of the tumor suppressor protein, Trp53. Thus, this patient has an increased risk of pancreatic Adenocarcinoma, the most common form of pancreatic cancer.
