Telomeres and Cancer

open access: yesLife, 2021
Telomeres cap the ends of eukaryotic chromosomes and are indispensable chromatin structures for genome protection and replication. Telomere length maintenance has been attributed to several functional modulators, including telomerase, the shelterin ...

Zinc Exposure Causes Disulfidptosis to Induce Miscarriage by Up‐Regulating GATA1/METTL1/SLC7A11 Axis

open access: yesAdvanced Science, EarlyView.
Zn exposure up‐regulates GATA1, promoting GATA1‐mediated METTL1 and SLC7A11 transcription. It also enhances METTL1‐mediated m7G modification on SLC7A11 mRNA, increasing SLC7A11 mRNA stability. Ultimately, Zn exposure up‐regulates SLC7A11 at both transcriptional and post‐transcriptional levels, causing disulfidptosis. Knockdown of murine Slc7a11, Gata1,

Telomerase reverse transcriptase promoter mutations in bladder cancer: High frequency across stages, detection in urine, and lack of association with outcome [PDF]

open access: yes, 2014
Background Hotspot mutations in the promoter of the gene coding for telomerase reverse transcriptase (TERT) have been described and proposed to activate gene expression.

Telomerase reverse transcriptase subunit immunoreactivity [PDF]

open access: yesCancer, 2002
AbstractBACKGROUNDTelomerase, a ribonucleoprotein complex that maintains telomeric DNA, has been detected in 67–93% of prostate carcinomas by telomeric repeat‐amplification protocol assay (involving polymerase chain reaction). One study used in situ hybridization in nine patients; however, to date, no immunohistochemical results have been published ...

Early Detection and Inhibition of Post‐Surgical Cancer Recurrence by Synthetic Extracellular Vesicles

open access: yesAdvanced Science, EarlyView.
An implantable hydrogel is designed to hold gene transfection agents engineered to turn early recurrent tumor cells into generators of synthetic EVs. These synthetic EVs can express engineered miR‐26a (E‐miR‐26a) for highly sensitive detection and PD‐1 (a PD‐L1‐blocking agent) for therapeutic intervention, thereby enabling early detection and ...

Expression of Telomerase Activity, Human Telomerase RNA, and Telomerase Reverse Transcriptase in Gastric Adenocarcinomas [PDF]

open access: yesModern Pathology, 2003
Telomerase is an RNA-dependent DNA polymerase that synthesizes TTAGGG telomeric DNA onto chromosome ends to compensate for sequence loss during DNA replication. It has been detected in 85-90% of all primary human cancers, implicating that the telomerase seems to be reactivated in tumors and that such activity may play a role in the tumorigenic process.

The simultaneous effect of valproic acid and gamma radiation on telomerase activity and bax and Bcl-2 protein levels in MCF-7 breast cancer cell line [PDF]

open access: yes, 2015
Background: Breast cancer is one of the most prevalent types of cancer. Factors such as ionizing radiation and chemotherapeutic agents can trigger apoptosis and cancer cell death.
