Effects of dietary fatty acids and cholesterol excess on liver injury: A lipidomic approach

Redox Biology, 2016
Lipid accumulation is the hallmark of Non-alcoholic Fatty Liver Disease (NAFLD) and has been suggested to play a role in promoting fatty liver inflammation. Previous findings indicate that during oxidative stress conditions excess cholesterol autoxidizes

Unveiling Candidate Markers for Drug Resistance or Synthetic Lethality in Cervical Cancer: Integrative Analysis of Genetic and Pharmacoprofiling

Cancer Reports, Volume 9, Issue 6, June 2026.
ABSTRACT Introduction Systemic cervical cancer management continues to be challenging. Numerous chemotherapies have been approved, but predicting response is difficult due to the lack of biomarkers. Here, we analyze the genetic and protein profiles of 20 cervical cancer cell lines (CCCLs) and explore their correlation with drug response patterns to ...

Olive oil polyphenols reduce oxysterols -induced redox imbalance and pro-inflammatory response in intestinal cells

Redox Biology, 2018
Dietary habits may strongly influence intestinal homeostasis. Oxysterols, the oxidized products of cholesterol present in cholesterol-containing foodstuffs, have been shown to exert pro-oxidant and pro-inflammatory effects, altering intestinal epithelial

On the rate of translocation in vitro and kinetics in vivo of the major oxysterols in human circulation

Journal of Lipid Research, 2002
Oxysterols possess powerful biological activities. Some of their effects on the regulation of key enzymes are similar to those of cholesterol, but are much more potent.

Physiology, pathology and therapeutic potential of microglial triggering receptor expressed on myeloid cells 2 signalling: A narrative update

Clinical and Translational Discovery, Volume 6, Issue 3, June 2026.
TREM2hi microglia and macrophages exert distinct roles in neurological diseases. Enhancing TREM2 signalling supports pathological protein or debris clearance and mitigates inflammation in Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, demyelination disorders and stroke, whereas blocking TREM2 may alleviate tauopathy and ...

Oxysterols in intestinal immunity and inflammation [PDF]

Journal of Internal Medicine, 2018
AbstractCholesterol is an essential molecule for life. It is a component of the cell membrane, and it is a precursor molecule for bile acids, vitamin D and steroid hormones. Cholesterol is actively metabolized, but the impact of endogenous cholesterol metabolites on immune function, especially in the intestine, is poorly understood.

Liver X Receptor α (LXRα) Regulates 5β‐Reductase (AKR1D1) Expression in Avian Embryos: Implications for Yolk Steroid Metabolism

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 5, Page 456-461, June 2026.
ABSTRACT Steroid‐mediated maternal effects are well‐studied as a source of phenotypic variation. In bird eggs, the yolk contains various steroids that can influence embryonic development. However, one complicating factor in understanding how yolk steroids affect development is that the embryo metabolizes yolk steroids to regulate exposure.

Changes in brain oxysterols at different stages of Alzheimer's disease: Their involvement in neuroinflammation

Redox Biology, 2016
Alzheimer's disease (AD) is a gradually debilitating disease that leads to dementia. The molecular mechanisms underlying AD are still not clear, and at present no reliable biomarkers are available for the early diagnosis.

Beyond the Known and Established Neurodegenerative Effects: Roles of APOE Across a Wide Spectrum of Pathophysiological Condition

MedComm, Volume 7, Issue 6, June 2026.
APOE is widely recognized for its role in neurodegeneration and cardiovascular disease, but its different genotypes also influence body composition, affecting obesity, bone density, and muscle mass, through their central role in lipid transport and metabolism.

A panel of altered blood oxysterols in patients with mild cognitive impairment: A novel combined diagnostic marker

Pharmacological Research
Perturbed cholesterol metabolism may play an important role in the development of dementia and its preclinical stage, mild cognitive impairment (MCI). Oxysterols, the metabolites generated during cholesterol oxidation, also appear to be risk factors for ...
