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).
Well, biotic factors are living things in an ecosystem such as animals or insects. Abiotic factors are non living things in an ecosystem such as sunlight or temperature. I would say biotic factors would be more harmful since this includes bacteria or other diseases, not many abiotic factors would pose a great threat to the entire human species. Hope this helped.
The different types of the Connective tissue are the Cartilage, Bone Tissue, White Adipose Tissue, Fascia, Fibrocartilage, Hyaline Cartilage, Elastic Cartilage, Costal Cartilage, Brown Adipose Tissue, and Adventitia....
Cartilage- Found in the Joints between bones, the elbow, your knees and ankles, the vertebrae, and on the end of ribs
Bone Tissue- Bone Tissue is found in small blood vessels, epithelium, and the nerves.
White Adipose Tissue- Is located beneath the skin, around internal organs, in bone marrow, and the breast tissue
Fascia-<span>This is the dense fibrous connective tissue that interpenetrates and surrounds the muscles, bones, nerves and blood vessels of the </span>body<span>. This suspends the organs within their cavities and wraps them in layers of connective tissue membranes.
Fibrocartilage- Found in the public </span>symphysis, the anulus fibrosis of intervertebral discs.
Hyaline Cartilage- Found in the Bronchi, bronchial tubes, costal cartilages, larynx, nose, and the trachea.
Elastic Cartilage- Found in the Epiglottis, and the Pinnae.
Costal Cartilage- Found at the anterior ends of the ribs.
Brown Adipose Tissue- Found in Neonates, brown fat<span> makes up about 5% of the body mass and is </span>located<span> on the back, along the upper half of the spine and toward the shoulders.
Adventitia- Is found in the Connective System and in the nerves.....
I hope this helps with this question you asked!!! It states the different types of the connective tissue and where they can be found!!!! Have a great </span>day!!!
