Cell Biology of Cancer - SEER Training
WEBThrough a number of biochemical steps, each gene tells a cell to make a different protein. Some genes instruct the cell to manufacture structural proteins, which serve as building blocks. Other genes tell the cell to produce hormones, growth factors or cytokines, which exit the cell and communicate with other cells.
Cellular and Molecular Basis of Cancer - The Merck Manuals
WEBThe cell cycle. G0 = resting phase (nonproliferation of cells); G1 = variable pre-DNA synthetic phase (12 h to a few days); S = DNA synthesis (usually 2 to 4 h); G2 = post-DNA synthesis (2 to 4 h)—a tetraploid quantity of DNA is …
Understanding Cancer - NIH Curriculum Supplement Series - NCBI Bookshelf
WEBIn simple terms, cancer is a group of more than 100 diseases that develop across time and involve the uncontrolled division of the body's cells. Although cancer can develop in virtually any of the body's tissues, and each type of cancer has its unique features, the basic processes that produce cancer are quite similar in all forms of the disease.
Exploring the Structural Biology of Cancer - RCSB: PDB-101
WEBStructural biologists are studying all aspects of this process, including the mechanisms that underpin damage to and repair of the genome, the way that these genetic changes lead to cancer, and ways for us to use this knowledge to discover and develop new treatments to …
The Development and Causes of Cancer - The Cell - NCBI …
WEBThe Development of Cancer. One of the fundamental features of cancer is tumor clonality, the development of tumors from single cells that begin to proliferate abnormally. The single-cell origin of many tumors has been demonstrated by analysis of X chromosome inactivation (Figure 15.2).
What Is Cancer? - NCI - National Cancer Institute
WEBOct 11, 2021 · Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are …
Graphical Guide To Cancer Biology - CancerQuest
WEBThis page presents a collection of graphics to explain key differences between normal and cancer cells. Most of the ideas shown below are explained in more detail on other pages. On this page we use only a few words and let the graphics provide the explanations.
Cells and Cell Structure - CancerQuest
WEBThe image below shows two living mouse cells. The mitochondria are colored red and the nuclei (with brightly stained chromosomes) are colored blue. The green colored region near the nuclei of the cells represents the golgi apparatus, an organelle involved in the processing and packaging of molecules within the cell.
The Biology of Cancer - Boston University School of Public Health
WEBExplain what is meant by "metastasis" and the mechanisms by which it occurs. List the mechanisms by which tumors cause harm. Explain the difference between the "grade" and the "stage" of a cancer. Describe the progressive stages in the evolution of breast cancer from normal to invasive ductal carcinoma.
Cancer cells - Cancer Research UK
WEBUnlike healthy cells, cancer cells don't carry on maturing or become so specialised. Cells mature so that they are able to carry out their function in the body. This process of maturing is called differentiation.
