- Abnormally high levels of prostate specific antigen (PSA) in a patient's blood is used to screen for prostate cancer. PSA is expressed in nomal, non-cancerous prostate cells. a) Why would elevated levels of PSA be suggestive of prostate cancer given what you know about cancer? Answer in no more than two sentences. b) Are high PSA levels sufficient to confim that a patient has prostate cancer, as opposed to a benign tumor? Why or why not? Explain in one sentence only.Select all of the sentences below that correctly describe the role of a healthy diet and lifestyle in cancer risk and progression. Select all that apply. A)Dietary supplements are definitively linked to lowering cancer risk. B)Consumption of processed meat containing nitrates and nitrites may increase a person’s risk of certain cancers. C)Grilling is a healthy cooking method; therefore, the consumption of all types of grilled meat will help reduce the risk of cancer. D)Folate may help reduce the incidence of colon cancer. E)Fruits and vegetables contain phytochemicals, antioxidants, and dietary fiber, all of which help reduce the risk of certain cancers.Tissues and differentiation a)Explain what is meant by termination and differentiation ).b) Explain the difference between an oncogenic and a tumour suppressor gene and describe how they are involved in the onset of cancer

Loss-of-function mutations could contribute to cancer progression if the mutant gene is, a) Rb b) Ras-GEF c) cdc25 d) cdks Help please! and explain if possibleWhat is inflammation? Describe the main characteristics of inflammation. What characterizes chronic inflammatory disorders? What is the role of NFkB in inflammation and cancer? What are the mechanisms and strategies to inhibit excessive and chronic inflammation? answer should be one page long1. a)Proteins that stimulate/promote progression through the cell cycle are encoded by (oncogenes or tumor suppressor genes). Boldface one. b)Proteins that inhibit progression through the cell cycle are encoded by (oncogenes or tumor suppressor genes). Boldface one. c)What is the difference between a proto-oncogene and an oncogene? d)To cause cancer, proto-oncogenes require (1 or 2)allele(s) to be mutated and therefore are considered (dominant or recessive). The mutation results in a (loss or gain) of function. For each underlined pair, boldface one. e)To cause cancer, tumor suppressor genes require (1 or 2)allele(s) to be mutated and therefore are considered (dominant or recessive).

Her doctors determined her breast cancer wasaggressive, which meant that she needed to undergo chemotherapy. Her doctors recommended a combination of docetaxel (Taxotere®), carboplatin, and trastuzumab (Herceptin®). The following is her blog entry after her second chemo treatment: As far as chemo symptoms go, the biggest has been fatigue. I was just tired, grumpy, and not my usual, peppy self most of the week. Other very minor things—tiny bit of stomach upset at the beginning of the week, but just enough to make me not feel like eating a big steak, not enough to keep me from eating soup or sandwiches. My scalp felt a little irritated—for the girls out there, itwas the feeling of having my hair in a tight ponytail all day and then letting it down, and the follicles just feel prickly—this is normal for several daysbefore the hair falls out. Also, I have a weird dry mouth feeling, so some things taste a little different. But seriously, these are really minor…. Download and read the attached review article (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5836099/pdf/EMBR-19-e45440.pdf) titled: Perturbing mitosis for anti-cancer therapy: is cell death the only answer?
- D. What is the best term for a normal INK gene? (tumor suppressor) (inactive tumor suppressor) (oncogene) (proto-oncogene) (oncogene or tumor suppressor) (beats me). E. Suppose you have cells that have permanently active ink protein as in C. The cells also have permanently active E2F or permanently active ras. (Consult texts or handouts for roles of E2F and ras.) E-1. If your cells have active E2F and active ink, then your cells should (grow normally) (fail to grow) grow uncontrollably) (can't predict). E-2. If your cells have active ras and active ink, then your cells should (grow normally) (fail to grow) grow uncontrollably) (can't predict).Which of the following statements correctly describes a characteristic of tumor-suppressor gene? a) they are frequently overexpressed in cancerous cells. b) they are cancer-causing genes introduced into cells by viruses. c) they encode proteins that help prevent uncontrolled cell growth. d) they often encode proteins that stimulate the cell cycle.The Bcl-2 protein was initially discovered via its ability to contribute to progression of B-cells to a cancerous "lymphoma" phenotype. 1) Define the mutation that was associated with the change in Bcl-2 in these cells. 2) Is Bcl-2 an oncogene or a tumor suppressor gene? 3) Define the role of Bcl-2 in normal cellular function and how this changed in Bcl-2 associated lymphoma.
