To understand gap junction activity in cancer cells, you do two experiments. First you inject a single normal cell in a group of normal cells that are surrounded by cancer cells with a dye. You observe that the dye spreads to the surrounding normal cells only (a). Then you inject a single cancer cell with the same dye and observe that the dye does not spread to any of the surrounding cells (b). la) Microinjed Suorescent dye gray Normal cell Fluorescent cell Cancerous ceļl white Ib) Fluorescent cell Which of the following is a logical interpretation of this experimental result ? O Fluorescent dyes are too big to move through gap junctions O Cancer cells have less actin than other cells O Cancer cells have increased gap junction activity O Cancer cells have reduced gap junction activity.

QUESTION 7 After you graduate, you are working at a laboratory that identifies a novel protein called Leprechaun. To determine in which organelles Leprechaun is found, you decide to express the Leprechaun gene in HeLa cells using a plasmid. Since you have generated an antibody that recognizes an epitope within the Leprechaun protein, which technique will you use to identify its localization within the HeLa cells? OA. SDS-PAGE O B. Immunocytochemistry O C. Western blot OD. Transmission electron microscopy (TEM) OE. Immunohistochemistry QUESTION 8 Which of the following statements regarding electron microscopy is TRUE? OA. White light is utilized to illuminate the sample for imaging in all types of electron microscopy. OB. Electrons pass through the object being examined in transmission electron microscopy (TEM). OC. In scanning electron microscopy (SEM) electrons, electrons bounce off the surface of the sample. OD. Electron microscopy can be used to view structures as small as 2 nm in…

Question -The FDA has authorized the use of direct-to-consumer testing for three mutations in BRCA genes that elevate cancer risk, but cautions that a negative result does not rule out increased cancer risk. How can this be true? A. It is impossible to trust companies that are selling genetic tests. B. They have a conflict of interest, and so the tests should be used for entertainment value only C. These tests are not highly accurate, and false negatives are possible. Individuals with a family history should have a negative result confirmed with a different test to be sure they are truly at low risk of developing cancer There are more ways to get cancer than a mutation in the BRCA gene. D. The test only detects three out of more than 1,000 known BRCA mutations. This means a negative result does not rule out the possibility that an individual carries other BRCA mutations that increase cancer risk..

QUESTION 13 What is the mechanism by which microtubules can rapidly shrink, or undergo â catastrophe?â A At low levels of ATP, tubulin subunits are not added to the + end of the microtubule. B At low levels of GTP, beta-tubulin subunits at the + end of the microtubule hydrolyze GTP, undergo a conformational change, and destabilize the filament so that the filament starts to disassemble from the + end. C At low levels of GTP, tau proteins are phosphorylated and bind to the microtubule to destabilize the + end. D At high levels of GTP, tubulin subunits are more quickly added to the â end than to the + end of the microtubule, resulting in a shrinking + end of the microtubule. E At low levels of ATP, the microtubules rapidly disassemble since ADP-bound tubulin subunits are lost at both the + and â ends of the filament.

Cancer stem cells (CSCs) are cancer cells (found within tumors or hematological cancers) that possess characteristics associated with normal stem cells, specifically the ability to give rise to all cell types found in a particular cancer sample. There are many biomedical engineering based approaches to detect CSCs. Question: What is the importance and advanatge of detecting Cancer stem cells (CSCs)? Please explain in details with your own words. Thank you.
