In a patient with a constitutively active receptor tyrosine kinase that increases the activity of PI3K, the administration of a drug that increases PTEN expression will likely inhibit tumorigenesis because; Group of answer choices PTEN prevents growth factor binding to RTK PTEN competitively inhibits the catalytic subunit of PI3K

Except for?, all of the following signals may trigger receptor conformational changes without reaching the plasma membrane. o a. Receptors for steroid hormones. Tyrosine kinase receptors are a kind of receptor that binds to tyrosine phosphatase. Voltage-gated ion channels (OC). G protein-coupled receptors (GPCRs).

Binding of a ligand (like TGFA) to a receptor tyrosine kinase (RTK) causes all of the following except (can use cell): OA. Dimerization of the receptor B. Auto-phosphorylation of the receptor O C. Activation of Ras through an interction with GRB2 (an adaptor) and SOS (a GEF) proteins. O D. Activation of heterotrimeric G proteins

Select statements that accurately describe receptor tyrosine kinases (RTKs). Some RTKs are dimeric in the presence of a ligand. GTPase activity is required for autophosphorylation (cross-phosphorylation). The structure includes a transmembrane helix. The intracellular domain has kinase domains.
Figure 9.8 HER2 is a receptor tyrosine kinase. In 30 percent
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.

Answered: NORMAL SIGNALING PATHWAY REQUIRES Ras
NORMAL SIGNALING PATHWAY REQUIRES Ras AND TWO PROTEINS, X AND Y signal molecule active Ras protein CYTOSOL GTP active receptor active signaling protein X tyrosine kinase The figure below shows how normal signaling works with a Ras protein acting downstream of an RTK. You examine a cell line with a constitutively active Ras protein.
