Cell Signaling Essay - 1583 Words

Defects of Cell Signaling Over the past semester in cell biology, determining protein structure and functions of gene sequences have been some important discussions in class. On this discussion, many people will agree that the defects from the protein structure and gene sequences such as cell-signaling are the main factors of human disease. When it comes to the topic of human disease breast cancer and sickle cell anemia have been the most prevalent. The importance of these topics in reference to breast cancer and sickle cell anemia are the background information on these diseases, the general population affected, what gene/proteins are involved in these diseases, the symptoms of the diseases, the experimental research, and the key†¦show more content†¦The fatty tissue known as glandular fibrous gives the breast its size and shape. In relation to the cause of breast cancer, it forms in the cell of these milk producing ducts and glandular tissue. Just like every other cancer, the cells will grow abnormally and divide more rapidly. The result of this factor will form swelling or lumps that could possibly spread though the lymph nodes and various parts of the breast. The rick factor is unclear to development of breast of cancer, but the factors are believed to be through the complexity, interaction, genetic makeup, and the environment. Breast cancer is a world-wide phenomenon. The ways in which it can be diagnosed is extremely important and to understand the symptoms could potentially save someone’s life. The signs and symptoms of breast cancer include a breast lump that may feel different from the surrounding tissue. There could be a change in the size, shape, or appearance of the breast. The skin of the breast could change, factors such as dimpling. Another factor could include the peeling, scaling, crusting of a pigmented area of the skin surrounding the breast. Lastly, there could also be redness or tenderness of the skin over the breast. There are also factors that can increase the risk of being diagnosed with breast cancer. The increased risk of breast cancer include being a female, increasing age, personal and family history, genetics,Show MoreRelatedNobel Prize for Cell Signaling Pathways Essay1268 Words   |  6 Pages or Medicine was awarded to James Rothman, Randy Schekman, and Thomas Sudhof for their pioneering research in cell signaling pathways. Together, they were able to solve many questions that we had about how this precise cell- ­Ã¢â‚¬ to- ­Ã¢â‚¬  cell regulation is carried out. With their works, many scientists across the world can apply their discoveries in variousRead MoreOverview of The Endocrine System713 Words   |  3 Pagesunderstanding how this system operates and what contributes to its failures can be helpful in understanding how the body contributes to overall health and wellness. The purpose of this essay is to highlight and describe the adreanal glands, an important component of the endocrine system. In this analysis, this essay will describe the location and normal physiology of the adrenal glands and discuss the hormones that are associated with this part of the body. Also the feedback mechanisms and communicationRead MoreTypes And Types Of Diabetes Essay1653 Words   |  7 Pageschaacterised by decrease in B cell mass function and decrease in the sensitivity of insulin in the peripheral tissues. Beta cell dysfunctioning decrease the release of amylin and insulin in response to increased blood glucose levels and this is thought to be affected by misfolded amylin proteins where the cytotoxicity from amylin oligomers affects the function of islet beta cells via several mechanisms and affecting the signaling pathway and apoptosis of beta cells.

These are lipids, carbohydrates, proteins and nucleic acids. They each play an important role in the synthesis and maintenance of cells. Lipids Lipids are organic compounds such as fats, natural oils, waxes and steroids. They are amphiphilic thus construct structures like vesicles and cell membranes in damp environments. Main functions of lipids are cell signaling, formation of cell membranes andRead MoreCentral Nervous System4535 Words   |  19 Pagesleads to become a spinal cord (1,2). Development of the CNS involves many complex mechanisms beginning at the onset of transformation of a single layer of ectodermal cells, the neuroectoderm until the end of the differentiation process resulting into highly complex structure involving variety of neural cell types (1,2). A large number of cell types need to be arranged spatially and temporally to form a complex structure during an embryo development. CNS being one such complex structure formed during embryonicRead MoreThe Viological Structure Of G-Protein Coupled Receptorss1463 Words   |  6 Pagesreceptors (GPCRs) are highly specialised proteins responsible for the transmis sion of signals across the cell membrane. They sense signaling molecules such as hormones and neurotransmitters, and thus play a very important physiological role in the human body (Venkatakrishnan et al., 2017). GPCRs are also known as metabotropic receptors, which indicates that they are involved in intracellular signaling. Scientific Background The results from numerous research were combined to create a model for the structureRead MoreHuman Neural Stem Cell Tropism857 Words   |  4 PagesARTICLE TITLE: Human Neural Stem Cell Tropism to Metastatic Breast Cancer ESSAY TITLE: The Investigation of a therapeutic implication on metastatic breast cancer with a specialized human neural stem cell that is programed to secrete carboxylesterase combined with activated form of an ionotecan by targeting a specific tumor site and major cytokine involved in mediating susceptibility of neural stem cells to breast cancer cells. SCIENTIFIC SUMMARY: Metastatic Breast Cancer is characterized as aRead MoreThe Role Of Proteins Of Cell Membrane Transport1276 Words   |  6 PagesDiscuss the role of proteins in cell membrane transport essay plan Cell membranes are surrounded by a phospholipid bilayer that provides a semipermeable barrier for cells, separating the cytosol from the extracellular environment. Phospholipids are ampithatic, meaning that they have a hydrophilic head and hydrophobic tail, which causes the heads to face outwards towards the water and the tails inwards, creating the bilayer [figure 1]. Small hydrophobic molecules such as O2 and CO2 and small unchargedRead MoreQuestions On Scientific Writing Skills705 Words   |  3 Pagestaking this medicine will be discussed in detail in Drug Review Essay.
