We have compared telomerase activity measurements by slab-gel and capillary electrophoresis in cultured cells (A549 and H125 human cancer cell lines) and in cells isolated from clinical peripheral blood specimens epithelial cells of patients with lung and esophageal cancer. Telomerase activity was determined using the telomerase repeat amplification(More)
BACKGROUND Telomerase is a ribonucleoprotein that maintains chromosomal telomere length. Telomerase is not active in nonmalignant somatic cells, but is activated in most human cancers. Telomerase activity in easily obtainable body fluids that bathe tumors may be a useful cancer marker, especially when used in conjunction with conventional cytology. (More)
The enzyme telomerase is expressed in (85-90)% of all human cancers, but not in normal, non-stem cell somatic tissues. Clinical assays for telomerase in easily obtained body fluids would have great utility as noninvasive, cost-effective methods for the early detection of cancer. The most commonly used method for the detection and quantification of(More)
