↳ Moving to another question will save this response. Question 20 According to many previous studies, stiffness of the pancreatic cancer cells is associated with increased invasive potential. Increased invasive potential means that the cancer cells are more likely to escape from the primary tumor and travel to other parts of the body. If you want to study the stiffness of the individual cells (assuming that the cells are not attached to each other), (1) what method would you want to use? And briefly explain why you choose this one. (2) briefly explain how the experiments should be carried out to measure the cell stiffness; (3) briefly discuss what data this experiment would generate; (4) briefly discuss how you would draw conclusions from the acquired data mentioned above.

D Question 78 One in five invasive breast cancers is HER2-positive, making this one of the more common breast cancer subtypes in the United States. HER2-positive cancers are ER- and PR-negative and human epidermal growth factor receptor 2 (HER2)-positive. Reading Comprehension Question. This is a description of one type breast cancer. HER2-positive breast cancer cells carry too many copies of the HER2 gene, which makes HER2- protein receptors, found on breast cells. When they work normally, HER2 receptors control how a healthy breast cell grows, divides, and repairs itself. When they proliferate, the receptors tell the cells to divide and grow rapidly and without control. That is because their cells absorb too much of a substance called human epidermal growth factor 2, which energizes cell growth. Doctors often test breast cancer tissue for excess HER2-positive genes to determine whether the patient may benefit from targeted therapy options, which are designed to block HER2 from…

Question:- 1. The complement pathway is a series of steps and the final steps lead to an effector function initiated by C3 or C5. Please name the effector function and describe the steps in the effector function of C5, (after C5b is produced). 2. CD8+ T cells and natural killer (NK) cells are two cells in the immune system with overlapping effector functions. List 5 similarities between these cell types, please organize your answer into a table or point form format. If you discuss cytokines please list specific names (ie IL-490, IFN-7).

Question 14 of 100 A mass in the adrenal gland was found incidentally on a CT scan in a 40-year-old male patient. True statement regarding this incidentally found adrenal mass is: Select one option A May be seen in as many as 10% of abdominal CT studies Most commonly represent pheochromocytoma; adrenocortical adenoma, adrenocortical carcinoma, and metastases from other primary cancers occur less frequently C May represent adrenocortical carcinoma if greater than 6 cm in diameter Should be routinely evaluated by measurement of 24-hour urine levels of catecholamines and their metabolites, cortisol, and aldosterone plus fine-needle aspiration
QUESTION 8 In the Results section of the paper, the authors' write: "Previous publications have shown that EGFR mutations are rare in human soft tissue sarcomas; therefore, activation of EGFR in studied specimens was possibly the result of appropriate ligand binding. To confirm this hypothesis, we analyzed the expression of EGF and TGF-alpha, the ligands for the EGFR. In the tumor microenvironment, EGFR ligands can be secreted both by tumor cells as well as by tumor-associated macrophages and fibroblasts." In the statement above, what text best refers to paracrine signaling? "EGFR mutations" O "EGFR ligands can be secreted both by tumor cells" "as well as by tumor-associated macrophages and fibroblasts" "appropriate ligand binding" QUESTION 9 For the following questions, refer to the PDF handout “EGFR mutations". This handout is from the company ATCC; they sell cancer cells to researchers for experiments. This page is titled "EGFR GENETIC ALTERATION PANEL. The first paragraph mentions…
Answer and explain your choice to the following multiple-choice questions about cancer-promoting mutations. The ABC gene undergoes multiple gene duplication events, producing multiple copies of this gene in the genome. This gene duplication event is associated with cancer. What would best describe the normal function of ABC gene? Inhibit cell growth and division Oncogene Inhibit apoptosis Metabolic enzyme EXPLAIN in 1-2 sentences: A mutation in the epidermal growth factor receptor (EGFR) causes it to send a positive signal along its intracellular signaling pathway, even without the EGF ligand bound to it. Knowing the function of a growth factor, how would you classify this mutation? an activating mutation in a tumor suppressor gene an activating mutation in a proto-oncogene a loss of function mutation in a tumor suppressor gene a loss of function mutation in a proto-oncogene EXPLAIN in 1-2 sentences: In an otherwise normal cell, what would be the immediate result of a…
Question is based on the following passage. Cancer is one of the leading causes of death in our society. Cancer is a disease in which a cell in the body loses its sensitivity to factors which regulate cell growth and division. The cell begins to multiply without restriction, creating a growing mass called a tumor, which interferes with the structure and functioning of the organ in which it is located. Frequently, cancer cells become metastatic, meaning that they travel, settling in a number of places and giving rise to secondary tumors. Much of medical research is devoted to finding ways of preventing, controlling, and curing cancer. Because of the metastatic trait of cancer cells, how can we judge a cancer treatment to be effective? A. if the original-source tumor has been identified B. if the entire body has been proven free of tumors over a period of time C. if the highest possible levels of treatment have been used D. if the complete tumor is removed E. if no new cancer cells are…
