Visualizing the end of the human genome

Researchers have discovered the structure of human POT1, a protein that caps the ends of chromosomes and regulates telomere length. The protein binds to a ten-nucleotide sequence, protecting the telomere from erosion, and its structure suggests that telomerase activity is regulated by this complex.

UCLA scientists uncork fountain of youth for HIV-fighting cells

Researchers at UCLA have discovered a protein that can keep HIV-fighting cells youthful and active, dividing endlessly and preventing telomeres from shortening. This breakthrough could lead to the development of new treatments for AIDS, cancer, and other diseases.

The telomere crisis: A crucial stage in breast cancer

Recent findings by scientists at Lawrence Berkeley National Laboratory and University of California, San Francisco, reveal telomere crisis as a key event in breast cancer progression. The researchers found that telomere length decreases in hyperplasia, carcinoma in situ, and invasive cancers, indicating increased genomic instability.

Discovery of chromosome-capping activator could aid cancer research

Researchers at Princeton University discovered a new activator protein Est1 that plays a key role in telomere capping. This finding contradicts existing theories and may offer a new target for cancer treatment. Est1 works by sweeping in with precise timing to activate the telomere-building process.

Human cancer-detection test showing promise in pets, too

Researchers at the University of Illinois have developed a simple protein test to detect telomerase activity in cancerous cells of dogs and cats. The test has shown promising results in diagnosing malignant tumors in pets, with high accuracy rates compared to traditional diagnostic methods.

Arsenic and old telomeres

Telomeres, protective caps on chromosome ends, are shorter in people exposed to arsenic, increasing cancer risk. Long-term arsenic exposure has been associated with accelerated telomere shortening, a potential biomarker for arsenic poisoning.

Size matters: Shortest telomeres initiate cellular havoc

The study found that critically short telomeres signal cells to arrest or die, rather than average length. Turning on telomerase can restore function without significantly increasing overall telomere length, offering new insights into cancer treatment options.

Study on chromosome ends may aid cancer research

A Princeton scientist has discovered a naturally occurring protein that inhibits telomerase, which replicates and lengthens chromosome ends. The protein, Pif1p, acts directly on the chromosome ends to keep the lengthening process in check.

Scientists issue telomerase caution

Researchers found that telomerase expression can activate the c-myc oncogene, a hallmark of cancer cells. This raises concerns about using telomerase in human tissue culture cells for therapeutic purposes.

Enzyme may protect nerve cells from brain disorders

Researchers found that telomerase blocks a biochemical cascade of reactions called apoptosis, which causes nerve cell self-destruction. High levels of telomerase display remarkable resistance to damage or death in experimental models of Alzheimer's disease or stroke.

Scientists clarify much-sought enzyme, pave road to cancer therapy

Researchers at Johns Hopkins describe fundamental shape of telomerase molecule in mammals and other vertebrates, identifying four common areas highly involved with the enzyme's working. This new information may prompt approaches to inhibit the enzyme, which is active in cancer cells and contributes to their continuous cell division.

Scientists cause human cancer cell death by inhibiting telomerase

Researchers at UT Southwestern Medical Center designed and tested synthetic inhibitors against telomerase, a key enzyme in cancer cell immortality. These inhibitors successfully caused progressive telomere shortening and cell death in human breast and prostate cancer cells.

Transformation of normal human cells into cancer cells

Researchers at Whitehead Institute successfully transformed normal human cells into cancer cells, shedding light on the complex process of tumor development. The new cell lines offer a unique window into the biochemical and physiologic changes that occur during cancer formation.

Telomere Loss Spells Trouble for Aging Mice

Mice lacking a gene for making telomeres displayed symptoms of aging, including graying hair and increased tumor incidence. However, the study reveals that telomere loss is not solely responsible for aging, suggesting other mechanisms at play.

Immortalizing Enzyme Does Not Make Human Cells Cancerous

Researchers demonstrate that human cells grown in the laboratory and immortalized by telomerase are not transformed into cancer cells, exhibiting normal behavior despite extended lifespan. The findings hold promise for new therapies for age-related diseases and cancer.

Telomeres and Telomerase

This book brings together international specialists to discuss the genetic structure of telomeres, telomerase function, and their importance in aging and cancer. The chapters cover topics such as telomere length regulation, chromosome end replication, and telomerase repressor genes.

Scientists Extend The Life Span Of Human Cells

Researchers at UT Southwestern Medical Center discover that telomerase causes human cells to retain their youth and continue dividing beyond their normal limit. The extension of normal cell lifespan in a youthful state presents numerous opportunities for biotechnology and medicine, including producing engineered products in human cells.
