Functional Suppression of SCAP Triggers Endoplasmic Reticulum Stress‐Dependent Ferroptosis by Impairing Cholesterol Metabolism in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
This study reveals a novel GC therapy targeting cholesterol homeostasis. Inhibiting the SCAP sterol‐sensing domain causes lethal ER stress via cholesterol accumulation, paradoxically forcing continuous synthesis that triggers ferroptosis. The findings link sterol sensing, metabolic dysregulation, and ferroptosis, establishing an anti‐cancer paradigm ...

Cholesterol overload in macrophages drives metabolic dysfunction-associated steatohepatitis via inhibiting 7-dehydrocholesterol reductase in mice

open access: yesJournal of Translational Medicine
Background Dietary cholesterol promotes metabolic dysfunction-associated steatohepatitis (MASH), with hepatic macrophages central to disease pathology. However, the mechanisms by which cholesterol-loaded macrophages influence MASH remain unclear. Methods

Expanding the Utility of Exome Sequencing in Preventive and Population Genetics

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Carrier screening is a long‐standing genetic testing process offered to at‐risk couples, with or without a family history, who might have pregnancies affected by an autosomal recessive (AR) or X‐linked (XL) disorder. A total of 276 unrelated individuals, initially referred for rare disorder screening by clinicians, were enrolled in this study ...

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

open access: yesBMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Clinical Utility of Nuchal Translucency Measurement in First‐Trimester Ultrasound Screening in a Setting With First‐Tier NIPT for Aneuploidy Screening

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective To investigate the additional clinical value of nuchal translucency (NT) measurement at the first‐trimester anomaly scan (FTAS) in a setting with first‐tier non‐invasive prenatal testing (NIPT). Method This nationwide prospective cohort study, part of the IMITAS study on FTAS implementation, included all pregnancies with increased NT

Association of Vitamin D, Zinc and Selenium Related Genetic Variants With COVID-19 Disease Severity

open access: yesFrontiers in Nutrition, 2021
Background: COVID-19 pandemic has proved to be an unrelenting health threat for more than a year now. The emerging amount of data indicates that vitamin D, zinc and selenium could be important for clinical presentation of COVID-19.

Genetic testing in paediatric neurological disorders

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
In this study 390 paediatric patients with neurological disorders underwent genetic testing via exome sequencing, commercial panel, in‐house epilepsy, and movement disorder gene panels. Exome sequencing provides the highest diagnostic yield, and severe developmental delay and hypotonia predicted pathogenic variants in the exome sequencing cohort ...

RAB4A acts as a negative feedback regulator of extracellular vesicle secretion during TGF‐β signaling

open access: yesThe FEBS Journal, EarlyView.
TGF‐β signaling regulates extracellular vesicle (EV) release in cancer cells by modulating the expression and activity of genes associated with EV biogenesis. The TGF‐β‐induced upregulation of RAB4A expression facilitates fast endosomal recycling, a process that limits the fusion of multivesicular bodies with the plasma membrane and EV secretion. Hence,

Craniofacial bone anomalies related to cholesterol synthesis defects

open access: yesScientific Reports
DHCR7 and SC5D are enzymes crucial for cholesterol biosynthesis, and mutations in their genes are associated with developmental disorders, which are characterized by craniofacial deformities.

Genetic analyses reveal a role for vitamin D insufficiency in HCV-associated hepatocellular carcinoma development. [PDF]

open access: yesPLoS ONE, 2013
Vitamin D insufficiency has been associated with the occurrence of various types of cancer, but causal relationships remain elusive. We therefore aimed to determine the relationship between genetic determinants of vitamin D serum levels and the risk of ...
