Reprogramming SREBP1‐dependent lipogenesis and inflammation in high‐risk breast with licochalcone A: A novel path to cancer prevention

International Journal of Cancer, Volume 158, Issue 7, Page 1927-1940, 1 April 2026.
What's new? Endocrine drugs repurposed from treatment protocols are the primary medications available for breast cancer (BC) prevention in at‐risk women. Adverse effects, however, significantly minimize uptake and prevention impact. Here, the authors investigated licochalcone A (LicA), a non‐endocrine anti‐inflammatory agent with reported hematologic ...

The multifaceted roles of the transcription factor SP1 in the pathogenesis of Alzheimer's disease: From molecular regulation to therapeutic targets

Alzheimer's &Dementia: Translational Research &Clinical Interventions, Volume 12, Issue 2, April/June 2026.
Abstract Alzheimer's disease (AD) is driven by interrelated pathologies, including the accumulation of amyloid β (Aβ), tau pathology, chronic neuroinflammation, and oxidative stress (OS). These pathological processes collectively lead to progressive neurodegeneration.

Prevention of Retinal Degeneration in a Rat Model of Smith-Lemli-Opitz Syndrome

Scientific Reports, 2018
Smith-Lemli-Opitz Syndrome (SLOS) is a recessive human disease caused by defective cholesterol (CHOL) synthesis at the level of DHCR7 (7-dehydrocholesterol reductase), which normally catalyzes the conversion of 7-dehydrocholesterol (7DHC) to CHOL ...

DHCR7: from sterol biosynthesis to oncogenic role in colorectal cancer [PDF]

PeerJ
Objective 7-Dehydrocholesterol reductase (DHCR7) is an enzyme that plays a crucial regulatory role in sterol biosynthesis and has been implicated in tumorigenesis and progression.

RNA‐Binding Proteins and Ferroptosis in Cancer: Mechanism and Therapeutic Implications

MedComm – Oncology, Volume 5, Issue 1, March 2026.
Ferroptosis critically influences cancer cell fate and represents a promising therapeutic strategy. Emerging evidence identifies RNA‐binding proteins (RBPs) as key post‐transcriptional regulators of ferroptosis. The figure summarizes ferroptosis‐related RBPs across cancers: blue RBPs act as tumor suppressors by promoting ferroptosis, whereas red RBPs ...

Elevated autophagy and mitochondrial dysfunction in the Smith–Lemli–Opitz Syndrome

Molecular Genetics and Metabolism Reports, 2014
Smith–Lemli–Opitz Syndrome (SLOS) is a congenital, autosomal recessive metabolic and developmental disorder caused by mutations in the enzyme which catalyzes the reduction of 7-dehydrocholesterol (7DHC) to cholesterol.

Lifespan‐Extending Endogenous Metabolites

Aging Cell, Volume 25, Issue 2, February 2026.
Endogenous metabolites act as mediators of longevity by modulating conserved cellular pathways. We summarize mechanistic evidence linking specific metabolites to lifespan and healthspan benefits across model systems, with discussion of clinical evidence, translational opportunities, and remaining knowledge gaps.

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, Volume 108, Issue 2, Page 676-693, February 2026.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Cholesterol Deficiency Directs Autophagy‐Dependent Secretion of Extracellular Vesicles

Journal of Extracellular Vesicles, Volume 15, Issue 1, January 2026.
Inhibition of cholesterol biosynthesis within models of rare disease and cancer causes increased release of small extracellular vesicles (sEVs) with distinct biological properties. Mechanistically, cholesterol depletion leads to impaired autophagic flux, redirection of autophagosomes to late endosomes, and subsequently increased sEV secretion ...

The use of the Dhcr7 knockout mouse to accurately determine the origin of fetal sterols

Journal of Lipid Research, 2006
Mice with a targeted mutation of 3β-hydroxysterol Δ7-reductase (Dhcr7) that cannot convert 7-dehydrocholesterol to cholesterol were used to identify the origin of fetal sterols.
