- "given the numerous processes inside cells that are regulated by changes in Ca+2 concentration, it seems likely that Ca¹²-dependent cell-cell adhesions are also regulated by changes in Ca2 concentration" is true or false.Cell adhesion molecules (CAMs) can form cis and trans interactions with other CAM molecules. True or FalseWhat is the main benefit of cell signaling via direct physical contact and cell signaling over short distances (ex: nerve cell signaling)?
- Neuropathy is often a side effect of anti-cancer drug treatments. Which of the following drugs induce neuropathy by disrupting microtubule formation thereby inhibiting axonal transport? Select ALL that apply Paclitaxel Oxaliplatin Vincristine Bortezomib Thalidomide CisplatinCell specializations are usually a modification or elaboration of one of the basic cell functions. (True or fa1se?)What is the main benefit of cell signaling via direct physical contact and cell signaling over short distqnces (ex.: nerve cell signaling)?
- Gap junctions and tunneling nanotubes are two distinct types of direct intracellular communication. In comparing and contrasting gap junctions and tunneling nanotubes, which of the following statements is true? gap junctions provide a portal for small molecules, proteins and small organelles to move from cell to cell, tunneling nanotubes only permit small molecules to pass between cells typically, there are only two gap junctions that exist between adjacent cells that are communicating via this mechanism; on the other hand, there are many tunneling nanotubes between communicating cells both gap junctions and tunneling nanotubes can pass small molecules between cells none of the above is trueThe best strategy for treating a specific type of human tumor can depend on identifying the type of cell that became cancerous to give rise to the tumor. For some tumors that have colonized a distant location (metastasized), identifying the parental cell type can be difficult. Because the type of IF protein expressed is cell-type-specific, using monoclonal antibodies that react with only one type of IF protein can help in this identification. What IF proteins would you produce monoclonal antibodies against to identify (a) a sarcoma of muscle cell origin, (b) an epithelial cell carcinoma, and (c) an astrocytoma (glial cell tumor)?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 CSCs? Please explain in detail the main findings with your own words.
