Early differential responses elicited by BRAFV600E in adult mouse models

open access: yesCell Death and Disease, 2022
The BRAF gene is frequently mutated in cancer. The most common genetic mutation is a single nucleotide transition which gives rise to a constitutively active BRAF kinase (BRAFV600E) which in turn sustains continuous cell proliferation.

Consequences of telomere dysfunction in fibroblasts, club and basal cells for lung fibrosis development

open access: yesNature Communications, 2022
Telomere dysfunction induced by TRF1 depletion in fibroblasts, club and basal cells did not lead to interstitial lung fibrosis, underscoring alveolar type II cells as the relevant cell type in pulmonary fibrosis.

Behind Base J: The Roles of JBP1 and JBP2 on Trypanosomatids

open access: yesPathogens, 2023
β-D-glucopyranosyloxymethiluracil (Base J) is a modified thymidine base found in kinetoplastids and some related organisms. Interestingly, Base J distribution into the genome can vary depending on the organism and its life stage. Base J is reported to be

Cell Cycle, Telomeres, and Telomerase in Leishmania spp.: What Do We Know So Far?

open access: yesCells, 2021
Leishmaniases belong to the inglorious group of neglected tropical diseases, presenting different degrees of manifestations severity. It is caused by the transmission of more than 20 species of parasites of the Leishmania genus. Nevertheless, the disease

The mTOR pathway is necessary for survival of mice with short telomeres

open access: yesNature Communications, 2020
Telomerase deficiency leads to age-related diseases and shortened lifespan, while inhibition of the mTOR pathway delays aging. Here, the authors show that inhibition of mTORC1 signaling shortens the lifespan of telomerase deficient mice.

TERRA regulate the transcriptional landscape of pluripotent cells through TRF1-dependent recruitment of PRC2

open access: yeseLife, 2019
The mechanisms that regulate pluripotency are still largely unknown. Here, we show that Telomere Repeat Binding Factor 1 (TRF1), a component of the shelterin complex, regulates the genome-wide binding of polycomb and polycomb H3K27me3 repressive marks to

Increase in short telomeres during the third trimester in human placenta

open access: yesPLoS ONE, 2022
An increase in telomere shortening in gestational tissues has been proposed as a mechanism involved in the timing for the initiation of parturition. An increase in very short telomeres with increasing gestational age has been observed in mice; this study

Sox4 Links Tumor Suppression to Accelerated Aging in Mice by Modulating Stem Cell Activation

open access: yesCell Reports, 2014
Sox4 expression is restricted in mammals to embryonic structures and some adult tissues, such as lymphoid organs, pancreas, intestine, and skin. During embryogenesis, Sox4 regulates mesenchymal and neural progenitor survival, as well as lymphocyte and ...

Mice with hyper-long telomeres show less metabolic aging and longer lifespans

open access: yesNature Communications, 2019
Telomere shortening is associated with aging. Here the authors analyze mice with hyperlong telomeres and demonstrate that longer telomeres than normal have beneficial effects such as delayed metabolic aging, increased longevity and less incidence of ...

Telomeres and telomerase as therapeutic targets to prevent and treat age-related diseases [version 1; referees: 4 approved]

open access: yesF1000Research, 2016
Telomeres, the protective ends of linear chromosomes, shorten throughout an individual’s lifetime. Telomere shortening is a hallmark of molecular aging and is associated with premature appearance of diseases associated with aging.
