Figure 9.8 HER2 is a receptor tyrosine kinase. In 30 percent of human breast cancers, HER2 is permanently activated, resulting in unregulated cell division. Lapatinib, a drug used to treat breast cancer, inhibits HER2 receptor tyrosine kinase autophosphorylation (the process by which the receptor adds phosphates onto itself), thus reducing tumor growth by 50 percent. Besides autophosphorylation, which of the following steps would be inhibited by Lapatinib? Signaling molecule binding, dimerization, and the downstream cellular response. Dimerization, and the downstream cellular response. The downstream cellular response. Phosphatase activity, dimerization, and the downsteam cellular response.

How does NF-kB induce gene expression? A small, hydrophobic ligand binds to NF-kB, activating it. Phosphorylation of the inhibitor Ik-B dissociates the complex between it and NF- kB, and allows NF-kB to enter the nucleus and stimulate transcription. NF-kB is phosphorylated and is then free to enter the nucleus and bind DNA. NF-kB is a kinase that phosphorylates a transcription factor that binds DNA and promotes protein production.

Can I get help on drawing a mechanism for the paragraph below? p53 stabilization by IR The signal upstream of p53 stabilization and activation after IR exposure most likely originate from DNA DSBs. This is supported by the fact that the kinases implicated in the phosphorylation of p53 are also implicated in DSB repair. These include two kinases that belong to the PI-3 kinase family, DNA-PK and ATM (see above), and indirectly, the checkpoint kinase 2 (Chk2). Ser15 of p53 was identified as a substrate for DNA-PK in vitro (Lees-Miller et al., 1992). Since DNA-PK is required for DSB repair in mammalian cells after IR exposure and since this residue falls within the MDM2-binding domain of the protein, this was an attractive model of p53 stabilization after IR. However, several recent reports have shown that Ser15 of p53 is phosphorylated in cells deficient in DNA-PK and that p53 accumulation in these cells is capable of generating cell cycle arrest or apoptosis after IR (Abraham et al.,…

Dr. Jace is a research officer in a laboratory that studies anticancer treatment. She is interested to test a plant extract for its apoptosis-inducing effect on colon cancer cells. After incubating the cells with the extracts, she is using the FITC Annexin V Apoptosis Detection Kit I by BD Biosciences for her apoptotic assay. Discuss the detection of apoptosis using this kit and include the utilization of flow cytometry in her experiment.
