Lecture notes from Imperial College London, Medical Biosciences, 2nd year, Cancer Biology (CBIO) module A crucial characteristic of every living cell is its ability to communicate with neighbouring cells. This interchange of information between a cell and its environment is what is known as cellular signalling. Specifically, a cell must be able to give precise responses to the environmental signals that it is continually receiving. Cell signalling pathways regulate all the key processes in...

What are the 5 well-known enzyme-linked cell surface receptors? - correct answer 1. Receptor Guanylyl Cyclase: produces cGMP 2. RTK: phosphorylate tyrosine residues leading to association of signalling molecules and cascade 3. TK Associated Receptors: associate with proteins having TK activity 4. Receptor Tyrosine Phosphates: Removes phosphate on tyrosine residues 5. Receptor Serine/Threonine Kinases: phosphorylate specific Serine/Threonine residues on IC signalling molecules How are...

What are opioids? - ANS Opioids: • Street use - not for physical pain states. • Patients (signalling in pain pathways) - used in presence of pain. Presence of opioid in presence of pain does not have same effect as recreational use. • Self administration and access, but patient controlled analgesia (PCA) also involves self administration. • Animals and patients pick doses. • Heroin vs morphine - same drug. • Pain must counter reinforcement. • Patients become physically dep...
