The significance of controlling the gene responsible for apoptosis phenomenon in age control

the significance of controlling the gene responsible for apoptosis phenomenon in age control In 1994, our laboratory attempted to extend the concept of apoptosis as defense mechanism and presented further data in support of this novel approach to the study of aging and to the novel hypothesis to account for the phenomenon 34 this view holds that genetically directed cell survival, under control of the process of apoptosis (programmed.

Start studying genetics ch 19 learn vocabulary, terms, and more with flashcards, games, and other study tools responsible for cell cycle control complex phosphorylates proteins to advance cell cycle cdk breaks down cyclins apoptosis - increases bax gene, represses bcl2 gene guardian of the genome p53 tsg. In addition to its importance as a biological phenomenon, defective apoptotic processes have been implicated in a wide variety of diseases excessive apoptosis causes atrophy , whereas an insufficient amount results in uncontrolled cell proliferation, such as cancer.

Two of the genes identified by rim have been shown to be involved in the control of apoptosis firstly, notch1 has been shown to play a crucial role in the control of cell fate, including the control of apoptosis (eg jundt et al, 2002. The realization that apoptosis is a gene-directed program has had profound implications for our understanding of developmental biology and tissue homeostasis, for it implies that cell numbers can be regulated by factors that influence cell survival as well as those that control proliferation and differentiation. Start studying genetics ch 19 learn vocabulary, terms, and more with flashcards, games, and other study tools -- cells = higher than normal mutation rates/ genomic instability b/c of mutations in genes controlling dna mismatch repair, leading ot accumulation of mutations called caspases, are responsible for initiating apoptosis and.

Apoptosis is consequently of profound significance in physiology, pathology and therapeutic medicine the analysis of the molecular mechanisms involved in apoptosis is therefore of great importance in developing gene and drug therapies for the many diseases where the control of apoptosis is perturbed. The 2002 nobel prize in medicine was awarded to sydney brenner, horvitz and john e sulston for their work identifying genes that control apoptosis the genes were identified by studies in the nematode c elegans and homologues of these genes function in humans to regulate apoptosis. Two of the genes identified by rim have been shown to be involved in the control of apoptosis firstly, notch1 has been shown to play a crucial role in the control of cell fate, including the control of apoptosis (eg jundt et al, 2002 . 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.

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. Two of the main types of genes that play a role in cancer are oncogenes and tumor suppressor genes learn more here it may be helpful to think of a cell as a car for it to work properly, there need to be ways to control how fast it goes or tell cells when to die (a process known as apoptosis or programmed cell death) when. In this review the incidence of apoptosis in the stem cells of both the small and large intestine will be discussed in relation to the expression of a number of apoptosis regulating genes (eg p53, bcl-2, bax) within these cells the importance of apoptosis as a means of controlling stem cell number (and therefore cellular output) will be addressed, as will the mechanisms by which any alterations to this process may contribute to malignancy.

The significance of controlling the gene responsible for apoptosis phenomenon in age control (967 words, 2 pages) when we gain control of the gene responsible for the phenomenon of apoptosis, we will be in control of agingwe are finding more evidence every day, indicating genetic links to all sorts of factors in the human being. The importance of apoptosis and cell cycle control in brain tumor etiology has also been suggested by the frequent presence of mutations or loss of expression of apoptosis/cell cycle control genes such as pten, cdkn2a, mdm2, tp53, nf1, and rb in brain tumors.

The significance of controlling the gene responsible for apoptosis phenomenon in age control

Evidence of a largely circumstantial nature suggests that some of the mechanisms of apoptosis control described in sections 3, 4, and 5 are deregulated in leukemia cells, thus contributing to their abnormal expansion and, in some cases, to drug and radiation resistance.

  • Research on apoptosis has increased substantially since the early 1990s in addition to its importance as a biological phenomenon, defective apoptotic processes have been implicated in a wide variety of diseases excessive apoptosis causes atrophy, whereas an insufficient amount results in uncontrolled cell proliferation, such as cancer.
  • Regulation and significance of apoptosis in the stem cells of the gastrointestinal epithelium dr c s potten , j w wilson and c booth this incidence appears to correlate with apoptosis being responsible for controlling the majority of intestinal epithelial cell loss.

Because the bcl-2 family of apoptosis-associated genes is critically involved in the control of apoptosis of human pmns,4 we studied whether a shift of balance between proapoptotic and antiapoptotic members of this gene family may be also responsible for the delay of pmn apoptosis in vivo. Extracellular control of cell division, cell growth, and apoptosis - molecular b extracellular control of cell division, cell growth, and apoptosis - molecular biology of the cell your browsing activity is empty.
