A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

open access: yesFEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

A p53-independent role for the MDM2 antagonist Nutlin-3 in DNA damage response initiation. [PDF]

open access: yes, 2011
BACKGROUND: The mammalian DNA-damage response (DDR) has evolved to protect genome stability and maximize cell survival following DNA-damage. One of the key regulators of the DDR is p53, itself tightly regulated by MDM2. Following double-strand DNA breaks

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Reduction of post-thawed sperm quality of Kacang goat using the addition of epigallocatechin-3-gallate into the skim milk–egg yolk extender

open access: yesOpen Veterinary Journal
Background: One native goat species in Indonesia that faces extinction because of cross-breeding is the Kacang goat (Capra hircus). In addition to ensuring food security as a meat-producing livestock, artificial insemination of the Kacang goat could ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Transcription influences repair-induced DNA methylation [PDF]

open access: yes, 2008
This work is aimed at the dissection of the molecular mechanism(s) linking DNA damage and gene silencing. To this end, we have developed a genetic system that allows a rapid assessment of homologous-directed repair (HR) of an unique DNA double strand ...

Declining semen quality in North Africa: from 2019 to 2024: retrospective multicentric study of 21,585 patients

open access: yesReproduction and Fertility
Recent evidence suggests a global decline in semen quality, raising significant concerns about male reproductive health. Data from North Africa are limited, and the region faces unique environmental and lifestyle challenges.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

open access: yesMolecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Super DNAging - New insights into DNA integrity, genome stability and telomeres in the oldest old

open access: yes, 2015
Reductions in DNA integrity, genome stability, and telomere length are strongly associated with the aging process, age-related diseases as well as the age-related loss of muscle mass.
