Increased duodenal iron uptake and transfer in a rat model of chronic hypoxia is accompanied by reduced hepcidin expression [PDF]

open access: yes, 2005
Background: Despite the requirement for increased iron delivery for erythropoiesis during hypoxia, there is very little information on how duodenal iron uptake and its transfer to the blood adapts to this condition.Aims: To assess the effects of 30 days ...

Spatial biology in cancer epigenetics

open access: yesMolecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Salidroside inhibited the proliferation of gastric cancer cells through up-regulating tumor suppressor miR-1343-3p and down-regulating MAP3K6/MMP24 signal molecules

open access: yesCancer Biology & Therapy
Salidroside inhibited the proliferation of cancer cell. Nevertheless, the mechanism has not been completely clarified. The purpose of the study is to explore the mechanisms of salidroside against gastric cancer. To analyze the changes of microRNA (miRNA)

Unraveling the epigenetic code in cancer cell–tumor microenvironment crosstalk

open access: yesMolecular Oncology, EarlyView.
Epigenetic regulation is a key driver of cancer development and progression. Diverse epigenetic alterations in cancer cells and components of the tumor microenvironment (TME) orchestrate their communication through multiple mechanisms. We discuss how the epigenetic code coordinates bidirectional cancer cell–TME crosstalk to promote cancer progression ...

Renqing Changjue alleviates sepsis-induced acute lung injury by regulating renin-angiotensin system and inhibiting inflammatory response

open access: yesImmunobiology
Sepsis, with high morbidity and mortality, represents a systemic inflammatory response syndrome. A common consequence of sepsis is acute lung injury (ALI).

Hypoxia and thrombosis [PDF]

open access: yesBlood, 2018
In this issue of Blood, Pilli and colleagues1 report that the essential antithrombotic factor protein S is inversely regulated by the transcription factor hypoxia inducible factor 1 (HIF1). This is an important contribution to our understanding of the molecular basis of the augmentation of thrombosis by hypoxia.

Profiling neoadjuvant therapy response in rectal cancer using meta‐analysis of publicly available transcriptomic RNA‐seq datasets

open access: yesMolecular Oncology, EarlyView.
This study integrates publicly available transcriptomic datasets to identify molecular signatures associated with response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer. By analyzing a combination of multiple cohorts with bioinformatics approaches, we reveal biological pathways and immune‐related features that may improve ...

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

open access: yesMolecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Hooray for Hypoxia?

open access: yesPLoS Medicine, 2005
The mortality of critically ill patients rises steadily as the partial pressure of arterial oxygen falls below about 11 kPa (80 mm Hg). A new animal study in the May 2005 issue of PLoS Biology showing a potential benefit for hypoxia is thus a challenge to current thinking.
