Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Metabolic Factors Associated with Endoscopic Atrophy, Intestinal Metaplasia, and Gastric Neoplasms in Helicobacter pylori-Positive Patients

open access: yesClinics and Practice
Background: Previous studies demonstrate an association between metabolic factors and Helicobacter pylori-related gastric cancer. However, the association of gastric atrophy or intestinal metaplasia (IM) with these factors remains unknown.

Exclusive development of T cell neoplasms in mice transplanted with bone marrow expressing activated Notch alleles [PDF]

open access: yes, 1996
Notch is a highly conserved transmembrane protein that is involved in cell fate decisions and is found in organisms ranging from Drosophila to humans. A human homologue of Notch, TAN1, was initially identified at the chromosomal breakpoint of a subset of

Comparison of the diagnostic accuracy of three current guidelines for the evaluation of asymptomatic pancreatic cystic neoplasms. [PDF]

open access: yes, 2017
Asymptomatic pancreatic cysts are a common clinical problem but only a minority of these cases progress to cancer. Our aim was to compare the accuracy to detect malignancy of the 2015 American Gastroenterological Association (AGA), the 2012 International

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Mucinous cystic neoplasm of the liver mimicking a hydatid cyst

open access: yesClinical Case Reports, 2021
Misdiagnosis of mucinous cystic neoplasms of the liver may have serious consequences due to their premalignant potential. A thorough understanding of their characteristic features and a high index of suspicion are mandatory (Mod Pathol, 24, 2011, and ...

Malignant hepatic vascular neoplasm with novel RAF1 and GNA11 mutations: Risk stratification considerations for hepatic small vessel neoplasm (HSVN)

open access: yesHuman Pathology Reports, 2022
GNAQ, GNA11, and GNA14 are paralogues in the GNAQ family that are mutually exclusively mutated in a group of vascular neoplasms with thin-walled capillary-like vasoformative growth, which occur at multiple sites.

PICALM::MLLT10 translocated leukemia

open access: yesFEBS Letters, EarlyView.
This comprehensive review of PICALM::MLLT10 translocated acute leukemia provides an in‐depth review of the structure and function of CALM, AF10, and the fusion oncoprotein (1). The multifaceted molecular mechanisms of oncogenesis, including nucleocytoplasmic shuttling (2), epigenetic modifications (3), and disruption of endocytosis (4), are then ...
