Cancer and oncogenes Biology Diagrams
Cancer and oncogenes Biology Diagrams cancer-causing retroviruses Retroviral insertion can convert a proto-oncogene, integral to the control of cell division, into an oncogene, the agent responsible for transforming a healthy cell into a cancer cell. An acutely transforming retrovirus (shown at top), which produces tumors within weeks of infection, incorporates genetic material from a host cell into its own genome upon infection
Cancer, being the most formidable ailment, has had a profound impact on the human health. The disease is primarily associated with genetic mutations that impact oncogenes and tumor suppressor genes (TSGs). Recently, growing evidence have shown that X-linked TSGs have specific role in cancer progression and metastasis as well. Mutations in proto-oncogenes, converting them into oncogenes, and mutations in tumor-suppressor genes can lead to uncontrolled cell proliferation and cancer development. This review explores key molecular pathways associated with these genes, highlighting their influence on cancer progression and treatment resistance, which are crucial for

"We distilled large compendia of information from millions of people diagnosed with any of the 13 most common cancer types, which constitute over 90% of all human malignancies," said Paul Khavari, MD, PhD, chair of dermatology."This enormous funnel of data allowed us to identify 380 variants that control the expression of one or more cancer-associated genes.
Proto-oncogenes are genes that normally help cells grow and divide to make new cells, or to help cells stay alive. When a the cell can start to grow out of control, which might lead to cancer. A proto-oncogene normally functions in a way much like the gas pedal on a car. It helps the cell grow and divide. An oncogene is like a gas pedal
Oncogene: Role in Cancer, Types, and Examples Biology Diagrams
What are oncogenes? An oncogene is a gene that may cause cancer.It's a mutated (changed) form of a normal gene, called a proto-oncogene, that manages cell growth.When proto-oncogenes mutate into oncogenes, they cause cells to grow and divide uncontrollably. Cancer is caused by alterations in oncogenes, tumor-suppressor genes, and microRNA genes. These alterations are usually somatic events, although germ-line mutations can predispose a person to
