Explanation:
Cyclins are proteins that regulate the progression through the cell cycle, i.e., the transition of G1 to S phase. It is well known that high cyclin expression may lead to cell proliferation states, which is closely associated with cancer progression. Moreover, the blockage of cyclins may have an anti-carcinogenic effect by inhibiting the progression through the cell cycle. MAP kinases are serine/threonine kinases that regulate the progression through the cell cycle by phosphorylating a variety of substrates during cell proliferation. In consequence, phosphatases that inactivate MAPK kinases (i.e., by dephosphorylation) may have an anticarcinogenic effect. The p53 is a tumor suppressor protein involved in diverse cellular processes including DNA repair, cycle arrest and programmed cell death. This protein (p53) is activated by phosphorylation at target residues and phosphatases inactivate it, thereby the blockage of its degradation may have an anticarcinogenic effect. Oncogene activation (i.e., the expression of oncogenes), may alter diverse cellular processes including DNA replication, and thereby may lead to cancer development. The G-protein α subunit is a GTPase that hydrolyses GTP and thus has a major role in controlling the kinetics of the G-protein signaling cascade. Platelet-derived growth factor receptors (PDGFR) are kinase receptors that play roles in regulating cellular differentiation, cell proliferation and cell growth. PDGFR receptors are present on the surface of normal cells, however, it has been shown that mutations of the PDGFR genes that lead to their high expression lead to uncontrolled cell growth and consequently cause cancer (i.e., by increasing PDGF signaling).
Answer:
The last one and the first one.
hope I could help you pls give this answer a hart thx
Explanation:
Answer:
DNA contains the instructions to help the cell survive. They help the cell produce protein in the stages of protein synthesis.
The nurse should include the
following instructions while performing preoperative teaching for an older
adult client who will be undergoing surgery to remove a cataract removed:
1. “A cataract is an opacity of
the lens, which may be as a result of aging, sunlight, or trauma.”
2. “A number of different types
of eye drops would have to be taken several times a day for up to 4 weeks after
the surgery.”
3. “A medication will be administered
to help you relax. You will also receive some different eye drops to dilate
your pupils and paralyze the lens."
4. "You are required to bring
sunglasses with you on the day of your surgery."
5. "Please, may I request you to show me how to put these natural tear
drops in your eyes?"
