Neoplasia: An International Journal for Oncology Research, 2001 We examined human telomerase reverse transcriptase (hTERT) protein distribution by immunohistochemistry in cultured cells and tissue sections. Cells with telomerase activity had nuclear positive signals whereas cells without telomerase activity did not ...

CHIP Promotes Human Telomerase Reverse Transcriptase Degradation and Negatively Regulates Telomerase Activity [PDF]
Journal of Biological Chemistry, 2010 The maintenance of eukaryotic telomeres requires telomerase, which is minimally composed of a telomerase reverse transcriptase (TERT) and an associated RNA component. Telomerase activity is tightly regulated by expression of human (h) TERT at both the transcriptional and post-translational levels.

The womb as the cradle of longevity: Perinatal origins of biological aging
International Journal of Gynecology &Obstetrics, EarlyView.Abstract The perinatal period is increasingly recognized as an important determinant of biological aging trajectories and disease susceptibility across the lifespan. This narrative review synthesizes current evidence linking intrauterine exposures to adult health outcomes across three biological dimensions: fetal programming, maternal influences, and ...

Cancer-associated TERT promoter mutations abrogate telomerase silencing
eLife, 2015 Mutations in the human telomerase reverse transcriptase (TERT) promoter are the most frequent non-coding mutations in cancer, but their molecular mechanism in tumorigenesis has not been established.

Anticancer potential of berberine: Molecular pathways and current clinical trial perspectives
JSFA reports, EarlyView.Abstract Cancer is constantly rising mortality rates due to its late prognosis, poor management, and expensive treatment. Multi‐sectoral approaches for cancer management include hygienic practices, synthetic drug exploitation, radiation therapy, and diet modifications.

Identification of human TERT elements necessary for telomerase recruitment to telomeres
eLife, 2014 Human chromosomes terminate in telomeres, repetitive DNA sequences bound by the shelterin complex. Shelterin protects chromosome ends, prevents recognition by the DNA damage machinery, and recruits telomerase. A patch of amino acids, termed the TEL-patch,

The FEBS Journal, EarlyView.Trim32 regulates the transition from proliferation to differentiation in C2C12 cells after myogenic induction. We found that, at the onset of differentiation, Trim32 destabilizes c‐Myc mRNA, promotes cell cycle exit, and enables normal myotube formation.

International Journal of Oncology, 2014 In human cancer, high expression of telomerase is correlated with tumor aggressiveness and metastatic potential. Human telomerase reverse transcriptase (hTERT), which regulates telomere length, can promote tumor development. Most research on hTERT has been focused on its crucial function of telomere maintenance.
