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),

Unraveling Lysosomal Exocytosis: From Molecular Mechanisms to Physiological Functions

Traffic, Volume 27, Issue 1, March 2026.
Lysosomal exocytosis is propelled by specific molecular mechanisms that direct its microtubule‐dependent transport and subsequent fusion with the plasma membrane. This process fulfills essential physiological functions such as plasma membrane repair, maintenance of cellular homeostasis, and participation in signal transduction.

Pathogenic mycobacteria achieve cellular persistence by inhibiting the Niemann-Pick Type C disease cellular pathway [PDF]

, 2016
Background. Tuberculosis remains a major global health concern. The ability to prevent phagosome-lysosome fusion is a key mechanism by which intracellular mycobacteria, including Mycobacterium tuberculosis, achieve long-term persistence within host cells.

Membralin Assembles a MAN1B1–VCP Complex to Target Foreign Glycoproteins from the Endoplasmic Reticulum to Lysosomes for Degradation

Advanced Science, Volume 13, Issue 9, 13 February 2026.
This study identifies Membralin as an ER‐phagy receptor that recruits MAN1B1 and VCP to form a selective ERLAD complex. By sensing dense N‐glycan clusters on viral fusion glycoproteins, this ubiquitin‐independent pathway directs SARS‐CoV‐2 spike, Ebola GP, influenza HA, and HIV‐1 Env to lysosomal degradation, thereby limiting viral infectivity ...

A Supramolecular Nanoscavengers: Based “Cargo‐Exchange” Breaking Cholesterol Metabolic Dysregulation for Glioblastoma Therapy

Advanced Science, Volume 13, Issue 7, 3 February 2026.
Dysregulated cholesterol metabolism, driven by a complex array of mechanisms, is a defining characteristic of glioblastoma (GBM). In this study, supramolecular nanoscavengers are engineered by harnessing the intrinsic binding affinity between endogenous small‐molecule cholesterol and β‐cyclodextrin (β‐CD).

The role of cellular adhesion molecules in virus attachment and entry [PDF]

, 2015
As obligate intracellular parasites, viruses must traverse the host-cell plasma membrane to initiate infection. This presents a formidable barrier, which they have evolved diverse strategies to overcome.

Ezetimibe blocks the internalization of NPC1L1 and cholesterol in mouse small intestine

Journal of Lipid Research, 2012
The multiple transmembrane protein Niemann-Pick C1 like1 (NPC1L1) is essential for intestinal cholesterol absorption. Ezetimibe binds to NPC1L1 and is a clinically used cholesterol absorption inhibitor.

Oligodendroglial Process Formation is Differentially Affected by Modulating the Intra- and Extracellular Cholesterol Content [PDF]

, 2012
Cholesterol is an essential component of eukaryotic plasma membranes and plays an important role in membrane organization and signaling processes. It is the major lipid component of detergent resistant caveolin-1 containing rafts which previously had ...
