Transformation of Some Selected Cells by Mistake

Malignant Transformation of Some Selected Cells by Mistake  [Pg.299]

How are the telomere ends treated in the trypanosoma cells rapidly (close to constitutively) replicating in liquid media While the mammalian blood stream form of the parasite may revert to that one residing in the insect vector (simulating trans-speciation) and virulence (mouse pathogenicity) may decline upon prolonged in vitro cultivation, the speed of replication is retained the telomeres are capped after each cell division [1287]. Unicellular life forms are able to sustain re-capped [Pg.300]

In the human bone marrow, fused to the nuclear protein and phosphatase PP2A inhibitor, SET (vide supra) and Nup-214 act together as an oncoprotein in acute myeloid leukemia [1290], as another example of cellular hyperploidy. [Pg.301]

Aneuploidy is consequential to mitotic errors malignantly transformed cells frequently commit mitotic errors. In fetal life, the developing human brain suffers of chromosomal segregational defects during mitoses of glial cells and neurons. Aneuploid brain cells are eliminated by apoptosis. Areas not cleared by apoptosis, remain confined to sites of chromosomal mosaicism. The presence of functionally active aneuploid neurons negatively affect neuron-to-neuron and neuron-to-gUal interactions [1291]. [Pg.301]

A patient with a fungating incurable cancer, immortalized and growing uncontrollably in the form of aneuploid cells, leaves the human society, unties the boat and sails deep in the ocean, where faUing in the water, dies. This malignant [Pg.301]
