- Outline the steps that lead to a cell becoming cancerous.Which of the following is not a characteristic of cancer cells? a. less cytoplasmic volume than normal cells b. an absence of cyclin c. loss of adhesion to other cells d. loss of control of cell division e. loss of normal control of G1/S phase transitionWhat is the significance of studying cell movement, particulary the epithelial-to-mesenchymal transition, in the study of cancer?
- Give the characteristics of cancer cells and distinguish them from normal cellsDescribe some hallmarks of malignant cells.Compare the characteristics of highly proliferating normal cells (including cells of the hair follicles, gastrointestinal tract, and bone marrow) with the characteristics of highly proliferating cancerous cells
- 1.The cells of cancerous tumors undergo changes that cause them to bear little to no resemblance to their original cell type. Predict how this will affect the ability of thise cells to perform thier function. A. Increased growth in the thickness in the alveolar tissue of lungs can allow fir more oxygen and can be detrimental if too much gas exchange occurs. B. Increase in abnormal growth in compact bone tissue can cause bones to become stronger. C. Tumor in the bladder can lead to the disproportionate growth of the epithelial tissue that allows the bladder to stretch; therefore, it will create a constant urgency to urinate. D. All choices are correct (I think it's between A and C but not sure which one)Which component of cell division machinery is frequently targeted by anti-cancer drugs? Can you explain the common side-effects of chemotherapy (e.g. hair loss, mucositis) based on this information?Name the six fundamental properties of malignant tumours. Which of these properties are amenable to study in a cell culture model of cancer and why?
