Immortalization and transformation of human cells.
The disruption of homeostatic mechanisms that regulate normal cell growth and proliferation is a hallmark of cancer. Experimentally, many of the same genetic changes that lead to abnormal cell proliferation conspire to confer replicative immortality upon cells in culture. Correspondingly, several lines of evidence implicate cellular immortalization as a prerequisite for cell transformation. Rec...
متن کاملcompactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
15 صفحه اولTelomerase induces immortalization of human esophageal keratinocytes without p16INK4a inactivation.
Normal human somatic cells have a finite life span and undergo replicative senescence after a limited number of cell divisions. Erosion of telomeric DNA has emerged as a key factor in senescence, which is antagonized during cell immortalization and transformation. To clarify the involvement of telomerase in the immortalization of keratinocytes, catalytic subunit of telomerase (hTERT) expression...
متن کاملNeoplastic transformation of immortalized human epidermal keratinocytes by ionizing radiation.
Efforts to investigate the progression of events that cause human cells to become neoplastic in response to ionizing radiation have been aided by the development of tissue culture systems of epithelial cells. In the present study, nontumorigenic human epidermal keratinocytes immortalized by adenovirus type 12 and simian virus 40 have been transformed by exposure to x-ray irradiation. Such trans...
متن کاملImmortalization of primary human keratinocytes by the helix-loop-helix protein, Id-1.
Basic helix-loop-helix (bHLH) DNA-binding proteins have been demonstrated to regulate tissue-specific transcription within multiple cell lineages. The Id family of helix-loop-helix proteins does not possess a basic DNA-binding domain and functions as a negative regulator of bHLH proteins. Overexpression of Id proteins within a variety of cell types has been shown to inhibit their ability to dif...
