49. The following experiment was designed to establish the synergy of Bcl2 with genes like Myc in leading to B- cell lymphomas Identify the figure that correctly represents conditions under which mice succumbed to lymphomas. The correct figure representing the conditions under which mice succumbed to lymphomas in the experiment designed to establish the […]
Following statements are made about some of the abnormally expressing proteins in human cancers: (1) Increased telomerase expression always contributes to increased cell death in cancer cells. (2) Overproduction of anti-apoptotic protein (Bcl2) can lead to inappropriate cell survival and is associate with chronic lymphoblastic leukemia (CLL). (3) The E5, E6 and E7 proteins encoded […]
Which one of the following statements about cancers is INCORRECT? (1) The c-myc gene is translocated to one of the immunoglobulin loci in a majority of Burkitt’s lymphomas. (2) Viral integration into the cellular genome may convert a proto-oncogene into an oncogene. (3) The functions of p53 and Rb are augmented by E6 and E7 […]

Cervical cancer-causing Papilloma virus produces two oncoproteins E6 and E7 which are responsible for interfering with cell cycle regulation by (1) inactivating Rb and p53, respectively (2) modulating p53 and pRb, respectively (3) binding to cyclin D1 and CDK4 (4)activating expression of p21 The cervical cancer-causing Papilloma virus produces two oncoproteins, E6 and E7, which […]
44. Present-day cancer treatment uses many approaches. Beyond surgery and radiation treatment, which are most often employed in cases of larger, more discrete tumors, drug therapies can be used to target residual tumor cells and to attack dispersed cancers. Chemotherapies by anti-cancer drugs are mostly aimed at blocking DNA synthesis and cell division. A list […]
