Cell Signaling

It allows cells to perform various cellular activities, coordinate, and interact with other cells. All cells of an organism receive signals from their environments and respond accordingly. Even the unicellular eukaryotes receive signals secreted by other cells and respond. In the case of yeast, mating takes place by signaling between the yeast cells. Communication by cell signaling in a multicellular organism has become a vast and important part of various fields of biology.

3. The role of the cytoskeleton in Hedgehog signaling (actin rearrangements, microtubules)a. The Smoothened protein localizes to the primary cilium of the target cells. Suppose there is amutation that impairs a protein involved in basal body formation. How do you think would thisaffect signaling through Smoothened? Make sure to define basal body, explain its function, andrelate it to Smoothened signaling. b. Cos2 and Fu bind to microtubules, localizing Ci/Gli to the cytoplasm. How do you think a mutationin a microtubule associated protein (MAP) that functions to stabilize microtubules would affectboth the microtubules and Hedgehog signaling? Make sure to describe the role of the protein,regulation of microtubule dynamics, and how this might affect cells when Hedgehog is bothpresent and absent.

Virtually all cancer treatments are designed to killcancer cells, usually by inducing apoptosis. However, oneparticular cancer—acute promyelocytic leukemia (APL)—has been successfully treated with all-trans-retinoic acid, which causes the promyelocytes to differentiate into neu-trophils. How might a change in the state of differentiation of APL cancer cells help the patient?

Below are two cell signalling pathways that work together to regulate cell growth, proliferation and ultimately the size of organs in O.Extremus. In other closely related organisms, dysfunction of these pathways has been associated with tumor growth. mTOR pathway: 1. Growth factors bind and stimulate the receptors. 2. Receptors can activate the phosphatidylinositol 3 kinase (PI3K) – Akt signaling pathway. 3. The activated Akt, a serine threonine kinase, inhibits theTSC1–TSC2 complex, allowing Rheb to activate mTORC1. 4. In parallel, amino acids activate the mTORC1 pathway through a mechanism requiring the Rag– Ragulator complex. Hippo pathway: 1. The binding of the ligand activates the receptors which activate Mst and Lats. 2. YAP activity is modulated by phosphorylation of Mst and Lats. YAP upregulates miR-29, which in turn downregulates PTEN, an inhibitor of PI(3)K and Akt. So, the two pathways crosstalk and coordinate cell number and growth. a) What purpose does this forward…

One important role of Fas and Fas ligand is to medi-ate the elimination of tumor cells by killer lymphocytes.In a study of 35 primary lung and colon tumors, half thetumors were found to have amplified and overexpressed agene for a secreted protein that binds to Fas ligand.

The retinoblastoma tumor suppressor gene Rb (RB1) codes forthe retinoblastoma protein (pRB). pRB prevents the progression of the cell cycle through G1 if DNA has been damaged. Itdoes so in part because it binds a transcription-activatingdimer referred to as E2F-DP. The pRB-E2F/DP complex recruits a histone deacetylase to chromatin. Explain.
I. The retinoic acid receptor (RAR) is a transcription factor that is similar to steroid hormone receptors. Thesubstance (ligand) that binds to this receptor is retinoicacid. One of the genes whose transcription is activatedby retinoic acid binding to the receptor is myoD. Thediagram that follows shows a schematic view of theRAR proteins produced by genes into which one oftwo different 12-base double-stranded oligonucleotides had been inserted in the ORF. The insertion site(a–m) associated with each mutant protein is indicatedwith the appropriate letter on the polypeptide map.For constructs encoding proteins a–e, oligonucleotide 1(5′ TTAATTAATTAA 3′ read off either strand) wasinserted into the RAR gene. For constructs encoding proteins f–m, oligonucleotide 2 (5′ CCGGCCGGCCGG 3′)was inserted into the gene.NH2 f g h i j k l m COOHa b c d eThe wild-type RAR protein can both bind DNA and activate transcription weakly in the absence of retinoic acid(RA) and strongly in RA’s presence.
