Malignancy without immortality? Cellular immortalization as a possible late event in melanoma progression

open access: yes, 2011
P>Cell senescence is a permanent growth arrest following extended proliferation. Cultured cancer cells including metastatic melanoma cells often appear immortal (proliferate indefinitely), while uncultured benign nevi (moles) show senescence markers ...

A New Paradigm: 46 Structural Cell Types Function as Environment‐Supporting Innate Immune Cells, With Endothelial and Vascular Smooth Muscle Cells as Key Prototypes

open access: yesiNew Medicine, EarlyView.
ABSTRACT The scope, organization, and biological significance of innate immune functions across structural cell types remain poorly defined. To address these fundamental knowledge gaps, we analyzed experimental data of transcriptomes generated by our group and others.

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

Reconceptualizing Aplastic Anemia—Seed, Worm, Soil

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
Aplastic anemia (AA) encompasses a group of hematological syndromes often misdiagnosed, resulting in a decrease in the overall blood cell count and representing a form of bone marrow failure. We reinterpret AA based on the “seed, worm, and soil” doctrine.

Colocalizing Telomeres With PML or γH2AX Foci by IF-FISH in Mouse Brain Neurons

open access: yesBio-Protocol
Telomere length maintenance is strongly linked to cellular aging, as telomeres progressively shorten with each cell division. This phenomenon is well-documented in mitotic, or dividing, cells. However, neurons are post-mitotic and do not undergo mitosis,

Nail Disorders in Systemic Conditions

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Nail findings in children can be indicative of an underlying systemic disease. Many of these findings are seen in multiple entities and are not specific to one disease. The importance of specifically examining for these nail changes cannot be overstated.

Telomeres: the silence is broken

open access: yes
The ends of linear eukaryotic chromosomes, telomeres, distinguish natural chromosome ends from DNA double stranded breaks and thus promote genome stability.

No overt nucleosome eviction at deprotected telomeres

open access: yes, 2008
Dysfunctional telomeres elicit the canonical DNA damage response, which includes the activation of the ATM or ATR kinase signaling pathways and end processing by nonhomologous end joining (NHEJ) or homologous recom-bination (HR). The cellular response to
