Targeting Brain Cholesterol Homeostasis in Alzheimer's Disease: Mechanisms and Therapeutic Perspectives

Journal of Neurochemistry, Volume 170, Issue 6, June 2026.
Brain cholesterol homeostasis is tightly regulated and largely independent of peripheral cholesterol. This review proposes a unifying framework in which aging, sex, and related biological stressors, including hypercholesterolemia, neurodegeneration, inflammation, and oxidative stress, converge to disrupt cholesterol homeostasis in the brain ...

Astrocytic TIA1‐Mediated Stress Granules Promote the Demyelination of Optic Neuritis by Sequestering mRNA of Cholesterol Synthesis Genes in an Experimental Autoimmune Encephalomyelitis Model

Advanced Science, Volume 13, Issue 23, 23 April 2026.
Astrocytic TIA1‐mediated stress granules (SGs) promote demyelination by sequestering the mRNA of cholesterol synthesis genes. In this model, astrocytic TIA1‐mediated SGs were increased in the optic nerves of EAE mice, leading to the downregulation of cholesterol synthesis genes such as HMGCS1 through sequestration of their mRNA into SGs, which ...

Estrogen Enhances FDFT1 Expression in Theca Cells of Chicken Hierarchical Ovarian Follicles by Increasing LSD1Ser54p Level Through GSK3β Phosphorylation at 216th Tyrosine

Biomolecules
The development of chicken ovarian follicles involves two key stages of primordial follicle recruitment and follicle selection that are tightly regulated by multiple reproductive hormones and cytokines.

Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Differential mRNA expression of seven genes involved in cholesterol metabolism and transport in the liver of atherosclerosis-susceptible and -resistant Japanese quail strains

Genetics Selection Evolution, 2012
Background Two atherosclerosis-susceptible and -resistant Japanese quail (Coturnix japonica) strains obtained by divergent selection are commonly used as models to study atherosclerosis, but no genetic characterization of their phenotypic differences has

Unilateral mastication‐induced memory deficits linked to disrupted hippocampal cholesterol metabolism in rats

VIEW, Volume 7, Issue 2, April 2026.
Unilateral mastication, a common oral habit, induces cognitive decline in rats by disrupting hippocampal cholesterol metabolism. It triggers astrocyte hyperplasia, enhances cholesterol synthesis, impairs transport/degradation, and reduces 24‐hydroxycholesterol (24‐OHC), ultimately damaging synaptic function.

Distinct roles and molecular mechanisms of nicotine and benzo(a)pyrene in ferroptosis of lung adenocarcinoma and lung squamous cell carcinoma

Tobacco Induced Diseases
Introduction The essence of ferroptosis is the accumulation of membrane lipid peroxides caused by increased iron, which disrupts the redox balance within cells and triggers cell death.

Targeting Autophagy in Ovarian Cancer: The Emerging Role of Ginsenosides

Cancer Medicine, Volume 15, Issue 3, March 2026.
ABSTRACT Background Ovarian cancer, the third most prevalent gynecological malignancy, is frequently diagnosed at an advanced stage owing to its asymptomatic early progression. Despite the application of conventional therapies, clinical management remains limited by adverse effects and the development of drug resistance.

The Contribution of Cholesterol and Squalene Synthase in Cancer: Molecular Mechanisms, Lipid Rafts and Therapeutic Approaches

Medicinal Research Reviews, Volume 46, Issue 2, Page 352-381, March 2026.
ABSTRACT A plethora of cellular signaling pathways are dysregulated in cancer cells, promoting carcinogenesis and migration. Cholesterol has recently been linked to cancer by several subcellular mechanisms, especially by its involvement in the formation of lipid rafts, which promote oncogenic signaling and cancer cell invasion. Squalene synthase (SQS),

Generation and characterization of iPSC‐derived microglia for in vitro modeling of stimuli‐specific neuroimmune responses

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Microglia are macrophage‐like brain resident immune cells known to express numerous Alzheimer's disease risk genes. Here we generated a human induced pluripotent stem cell (iPSC) derived microglia cell culture model for use in neuroimmune modeling and therapeutic testing.
