As creatures of the light, it is natural for us to fear the dark unknown of death. However, if we only knew how prevalent death is in our lives, perhaps we would not be so afraid or disgusted by it. For it is death that keeps our body running functionally, and giving the organ systems physical definition, enabling them to work properly. The building blocks of our bodies-- cells-- are alive and constantly growing, and if they continued to do so without pause, our organ systems would become enlarged and misshapen, and we as an unified organism would die. Therefore, our cells commit suicide on a regular basis via programmed cell death, more commonly referred to as apoptosis; this is done either to cull excess cells to give way to new ones, or when cells start malfunctioning and don’t want to reproduce. Apoptosis should not be confused with its foil, cell necrosis, which is is another death system that kicks in when cells and tissues are dealt trauma, and it is highly irregular, as opposed to the regulated apoptosis. Each death system has its own purposes in the body, and the interruptions of these small deaths can ultimately lead to the death of the entire organism-- life is not merely followed by death-- it is supported by it.
The apoptosis process is a fairly recent medical discovery, as intensive research had only begun in the late 1900s, leading Drs Brenner, Horvitz and Sutton to their ground-breaking discoveries in the field, earning them the Nobel Prize in Medicine (Hung and Chow, 2004). Their research began in Caenorhabditis elegans, which has more simple DNA and body processes than mammals. However, it was soon discovered that the genes which regulate apoptosis in the nematode are similar to those in large orga...

Gaining Control of the Gene Responsible for Apoptosis Essay - Gaining Control of the Gene Responsible for Apoptosis When we gain control of the gene responsible for the phenomenon of apoptosis, we will be in control of aging. We are finding more evidence every day, indicating genetic links to all sorts of factors in the human being. We are just now beginning to scratch the surface of our own genetics. A landmark discover has just been unveiled: In February [2001], the two groups charting the human genome published their results—the entire 3 billion base pair sequence....   [tags: Apoptosis Aging Genetics Essays]

Essay on Immunity to Parasites and Apoptosis - IMMUNITY TO PARASITES AND APOPTOSIS. Humoral and cellular immunity are the two sides of immunity turn on during parasitic infections and ideally are aimed to fight infection. However, in some cases immunity to parasites can exacerbate the disease and induce tissue injury. Cellular Immunity Animal models have been most useful to better understand mechanisms of immunity to parasites. Athymic mice that lack T cells are unable to control several parasite infections. This clearly indicates that T cells play an important role during the development of these infections (39,40)....   [tags: Biology, Cellular Immunity] 1925 words

A Cure for Cancer Essay - For years people have been looking for a cure for the devastating disease of cancer. Cancer is the third highest killer in the US with over 2,500,000 victims per year. Oncologists and scientists around the country are researching all forms of cancer in an effort to understand, treat, and ultimately defeat this disease. Already there have been numerous advances in the field, such as chemotherapy and gene therapy. One advance has been the use of a cell process known as apoptosis. By harnessing this normal cell process, scientists hope to have found an effective way to combat cancer....   [tags: Biology Apoptosis] 3015 words

Essay about Eulogy of Eukaryotes - ... (Clot) However, the effect of dead cells has always played a role in a transformation several orders of magnitude larger since the agricultural revolution. Each day my body will typically flip the switch on over 10 billion cell via programmed death - a process called apoptosis (Alb). Many of my cells will pass away along the epidermis, and 'scavenger cells', or phagocytes, can gobble up the rest for digestion and excretion as fecal waste. (Alb) While much of ancient eastern society reused its cells as crop fertilizer for millennia, the west I originate from resisted this night soil until recent centuries....   [tags: apoptosis, cells, death]

Hypoxia-mediated Selection of Cells with Diminished Apoptotic Potential in Solid Tumours - Cancer: Necrosis vs. Apoptosis Cancer is the second leading cause of death in humans. A cancer cell is a cell that has mutated from its original form and will often grow at a more rapid rate than normal. The body has built certain mechanisms to protect itself from these types of cells. One of the physiological processes the body uses to kill off these cells is apoptosis. Apoptosis is sometimes called "cell suicide". When the body detects that a cell's DNA has mutated and cannot be repaired, the cell will somehow trigger itself to self destruct....   [tags: Biology Cancer Necrosis Apoptosis] 751 words

Phases of Wound Healing Essay examples - (A)Wound healing is a biological process occurring in the human body. In this lecture we had discussed about both acute and chronic wounds. An acute wound is an injury to the skin that occurs suddenly rather than over time. It heals at a predictable and expected rate according to the normal wound healing process. The chronic wounds do not heal in an orderly set of stages and in a predictable amount of time the way most wounds do. The normal wound healing process mainly consists of four main stages being haemostasis, inflammation, proliferation or new tissue formation, and tissue remodeling or resolution....   [tags: injury, skin, healing process, chronic wounds]

Fungi and apoptosis Essay - Cancer is one of the leading causes of death worldwide and according to the WHO it accounted for approximately 7.6 million deaths in 2008 (WHO, 2011). The most prevalent forms of cancer present in the United States are breast and prostate cancer (American Cancer Society, 2011). Over the past decade anticancer drugs and cancer treatment have made inadequate progress. However today, there is a greater understanding of the molecular basis behind the formations of tumorigenesis. This knowledge combined with the molecular diversity of natural compounds such as those found in mushrooms have paved the way for the discovery of new drugs....   [tags: Medical Research]

The Writing Process Essay - Scores of composition instructors agree that writing should be taught as a recursive process, rather than a liner process, and they also agree that most writers employ certain writing strategies as they produce drafts. Sandra Perl’s article, Understanding Composing” shares these beliefs because she states: “writing does appear to be recursive, yet the parts that recur seem to vary from writer to writer and from topic to topic” (142). Perl explains that throughout the writing process, writers employ a “forward-moving action that exists by virtue of backward-moving action” (141)....   [tags: Education, Recursive Process] 988 words
