Cancer is a complex process involving a multi-faceted evolutionary process occurring at the cellular level within organisms. It is triggered by the second law of thermodynamics (disorder increases in ...

Telomerase is a ribonucleoprotein enzyme that maintains the protective structures at the ends of eukaryotic chromosomes, called telomeres. In most human somatic cells, telomerase expression is ...

Scientists have for the first time mapped telomerase, an enzyme which has a kind of rejuvenating effect on normal cell aging. The findings are a step forward in the fight against cancer. In ...

Researchers at Arizona State University’s (ASU) School of Molecular Sciences and the Biodesign Institute’s Center for the Mechanism of Evolution have discovered an unprecedented pathway producing ...

Research has recently uncovered a crucial step in the telomerase enzyme catalytic cycle. This catalytic cycle determines the ability of the human telomerase enzyme to synthesize DNA. Research from the ...

Premature aging can be reversed by reactivating an enzyme that protects the tips of chromosomes, a study in mice suggests. Mice engineered to lack the enzyme, called telomerase, become prematurely ...

Telomeres – which are the DNA repeats that form the tips of chromosomes and are produced by the telomerase enzyme – play a crucial, and curious, role in the life of the cell. While chromosomes are ...

Sometimes stories that start with pond scum can have good endings. In the case of the single-celled organism called Tetrahymena thermophila, important bits of DNA at the ends of its chromosomes led to ...

A study by Children's Medical Research Institute (CMRI) researchers reveals a new group of proteins that guide the powerful enzyme telomerase, opening potential doors to novel treatments for cancer, ...

Science has identified in the plant kingdom the “missing link” of cellular immortality between human and single-celled animals, according to a new study led by scientists from Arizona State University ...
