Move beyond free radical theory of aging
Free radicals play a dual, dose‐dependent role in aging. Low levels activate the key sensor adenosine 5'‐monophosphate‐activated protein kinase (AMPK), promoting cell survival mechanisms like autophagy and enhancing mitochondrial health. High levels, however, push AMPK to initiate cell death pathways, such as apoptosis. This positions AMPK as a central

Abstract Historically, immunological memory was considered an exclusive feature of adaptive immunity. However, innate immune cells have recently been shown to record and maintain epigenetically imprinted memory of earlier infectious or inflammatory challenges.

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 ...

Telomerase is expressed in early human development and then becomes silenced in most normal tissues. Because ~90% of primary human tumors express telomerase and generally maintain very short telomeres, telomerase is carefully regulated, particularly in ...

ABSTRACT Molecular diagnostics have become an important adjunct to ultrasonography and fine‐needle aspiration (FNA) for thyroid nodules, especially in Bethesda III/IV cytology where malignancy risk is uncertain. This narrative review summarizes the diagnostic and prognostic value of key genomic drivers (BRAF V600E, RAS, RET, TERT, and selected fusions)

Oxidative guanine base damage regulates human telomerase activity
Changes in telomere length are associated with degenerative diseases and cancer. Oxidative stress and DNA damage have been linked to both positive and negative alterations in telomere length and integrity. Here we examined how the common oxidative lesion

ABSTRACT Psychological stress (or simply “stress”) is a major contributor to chronic disease worldwide, affecting 35% of the global population, including younger generations. Furthermore, it plays a significant role in human premature aging; hence, its detrimental effects on people's health compel us to comprehend and control the ways in which ...

Telomeres are considered anti‐cancer targets, as telomere maintenance above a minimum length is necessary for cancer growth. Telomerase abrogation in cancer‐prone mouse models, however, only decreased tumor growth after several mouse generations when ...
