Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Phosphorylation of Extracellular Signal-Regulated Kinase after Transient Cerebral Ischemia in Hyperglycemic Rats

Neurobiology of Disease, 2001
The present study was undertaken to investigate whether extracellular signal-regulated kinase (ERK) was involved in mediating hyperglycemia-exaggerated cerebral ischemic damage. Phosphorylation of ERK 1/2 was studied by immunocytochemistry and by Western

Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations

Advanced Functional Materials, EarlyView.
Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and

Relationships between summer Thermal variations and cell proliferation in heterothermic vertebrates, as revealed by PCNA expression in the brain of adult Rana bergeri (Günther, 1986) [PDF]

, 2018
About the issue if the natural encephalic proliferative activities can be infl uenced by the seasonal (thermal and photoperiodic) cyclic fl uctuations in adult earth-dwelling Anamnia and poikilothermal Amniota there is a gap regarding expressly summer ...

Functional Hydrogel for Modulating Lipid Droplets and Neuroinflammation in Head Injury

Advanced Functional Materials, EarlyView.
After TBI, elevated cholesterol levels in activated microglia lead to the accumulation of cholesterol esters in lipid droplets, exacerbating neuroinflammation. A β‐cyclodextrin‐conjugated GelMA (βCD‐GelMA) hydrogel is developed to promotes cholesterol efflux and reduces LDL influx, thereby alleviating intracellular cholesterol and lipid droplet buildup.

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

Hepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Calcium-sensing receptor activation increases cell-cell adhesion and ß-cell function [PDF]

, 2012
Background/Aims: The extracellular calcium-sensing receptor (CaR) is expressed in pancreatic β-cells where it is thought to facilitate cell-to-cell communication and augment insulin secretion.

Estrogen receptor immunocytochemistry. [PDF]

Journal of Histochemistry & Cytochemistry, 1978
Estrogen receptor activity was preserved in fixed, paraffin-embedded tissue and demonstrated by binding of estrogen which, in turn, was detected immunocytochemically. Estrogen was added to rat endocervial epithelium to protect specifically receptors during fixation.
