(a)
To determine: The way in which given treatment would be expected to stimulate or inhibit apoptosis.
Introduction: The given situation is “Cells are treated with a small molecule called pifithrin-a, which was originally isolated for its ability to reversibly block p53-dependent transcriptional activation”.
(b)
To explain: The way in which given treatment would be expected to stimulate or inhibit apoptosis.
Introduction: The given situation is “Exposing cells to recombinant TRAIL protein, a ligand for the tumor necrosis factor family of receptors”.
(c)
To explain: The way in which the given treatment would be expected to stimulate or inhibit apoptosis.
Introduction: The given situation is “Treatment of cells with organic compounds that enter the cell and bind with high affinity to the active site of caspase-3.”.

What does it mean that a signal is G protein connected?arrow_forwardtrue or false? And why it is false For the actin cytoskeleton, diverse cell-surface receptors trigger global structural rearrangements in response to external signals. But all these signals seem to converge inside the cell on a group of closely related monomeric GTPases that are members of the Rho protein family—Cdc42, Ras, and Rho. The same Rho family proteins are also involved in the establishment of many kinds of cell polarity.arrow_forwardTrue or Falso. Both p53 and kinesins can become phosphorylated.

- Cell signaling The maximum secretion rates of proteins are one type of limiting constraint on signal-ing processes since a cell cannot send a signal faster than it can secrete it. These maximum signalingrates can be estimated with maximum rates of transcription and translation. Consequently, proteins withstrong promoters can be synthesized at much higher rates. Immunoglobulins, which are important signal-ing molecules, have very strong promoters. Their maximum secretion rate is on the order of 2000 to 8000antibody molecules/cell/second, which corresponds to approximately 1 pg/cell/hr. Part AWhat would be the maximum signal (in pg/cell/hr) that a cell could send for the following situations: (1)Signal molecule A has a MW = 100,000 daltons and is secreted at a rate of 1000 molecules/cell/second. (2)Signal molecule B has a MW = 50,000 daltons and is secreted at 5000 molecules/cell/second.Part BWhich molecule is secreted at a higher rate?

UVR stimulates the expression of POMC by keratinocytes. The peptide produced is the precursor of the hormone a-MSH, that binds to MC1R in melanocytes. This union leads to an increase in cellular cyclic adenosine monophosphate (cAMP) that in turn leads to increased levels of MITF expression, which upregulates the transcription of TYR, TYRP1 and TYRP2, producing brown-black eumelanin. In the absence of a-MSH, the antagonist ASIP binds to MC1R, and phaeomelanin is synthetized instead. Melanosomes are then transferred to keratinocytes through the dendrites via a shedding vesicle system." Briefly discuss how these several aspects of the molecular and cellular biology of melanin production and melanosome transfer contribute to determine skin color. How would different mutations in the hormonal response to ultraviolet light, the melanin production signal transduction pathways, and melanosome transfer influence skin color, hair color, and eye color?
