A caveolin dominant negative mutant associates with lipid bodies and induces intracellular cholesterol imbalance [PDF]

open access: yes, 2001
Recent studies have indicated a role for caveolin in regulating cholesterol-dependent signaling events. In the present study we have analyzed the role of caveolins in intracellular cholesterol cycling using a dominant negative caveolin mutant. The mutant

Caveolin-1 in Cell Migration and Metastasis

open access: yesCurrent Molecular Medicine, 2014
Caveolin-1 is a member of the caveolin family that has been ascribed a dual role in cancer. In early stages of disease the protein functions predominantly as a tumor suppressor, whereas at later stages, caveolin-1 expression is associated with tumor progression and metastasis. Here, some mechanisms associated with caveolin-1-dependent tumor suppression

Piezo1 Channel Mediates Mechanically Programmable Drug Delivery to Potentiate Intravesical Chemotherapy

open access: yesAdvanced Science, EarlyView.
This study utilizes programmable mechanical pressure as a therapeutic enhancer to establish a mechano‐chemotherapy strategy. Controlled pressure activates the mechanosensitive ion channel Piezo1 in bladder cancer, triggering a calcium ion cascade that transiently and reversibly amplifies membrane permeability to chemotherapeutics.

Caveolin-1 mediates the utilization of extracellular proteins for survival in refractory gastric cancer

open access: yesExperimental and Molecular Medicine, 2023
Despite advances in cancer therapy, the clinical outcome of patients with gastric cancer remains poor, largely due to tumor heterogeneity. Thus, finding a hidden vulnerability of clinically refractory subtypes of gastric cancer is crucial.

Sirtuin1 protects endothelial Caveolin-1 expression and preserves endothelial function via suppressing miR-204 and endoplasmic reticulum stress. [PDF]

open access: yes, 2017
Sirtuin1 (Sirt1) is a class III histone deacetylase that regulates a variety of physiological processes, including endothelial function. Caveolin1 (Cav1) is also an important determinant of endothelial function. We asked if Sirt1 governs endothelial Cav1

Caveolin-1 and Lipid Rafts in Confluent BeWo Trophoblasts: Evidence for Rock-1 Association with Caveolin-1

open access: yesPlacenta, 2007
Lipid rafts are detergent-insoluble, low-density membrane domains that are rich in cholesterol and sphingolipids; caveolae are a subdomain of the biochemically defined glycolipid raft whose expression is associated with the protein caveolin-1. This protein associates with numerous signalling molecules, regulating their activity by holding them inactive.

Caveolin‐1 Stabilizes SERCA2 to Counteract Acute Kidney Injury via Suppression of Ca2+‐Dependent Endoplasmic Reticulum Stress in Distal Tubules

open access: yesAdvanced Science, EarlyView.
In AKI, initial kidney injury upregulates the expression of Cav‐1, which subsequently binds to and stabilizes SERCA2 via its scaffolding domain and through deubiquitination, thereby regulating Ca2+ homeostasis and ER stress. Conversely, Cav‐1 deficiency accelerates SERCA2 degradation, triggering Ca2+ overload and ER stress, and ultimately exacerbating ...

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

open access: yes, 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 ...

GLS1 Orchestrates Exosome‐Mediated Tumor‐Endothelial Communication to Facilitate Angiogenesis

open access: yesAdvanced Science, EarlyView.
This study reveals a previously unappreciated, non‐metabolic function of GLS1 in the control of tumor angiogenesis via exosome‐mediated CAV1‐TNC signaling, indicating that therapeutic targeting of GLS1 may offer a dual benefit by simultaneously suppressing tumor metabolic activity and angiogenic processes in head and neck cancer. ABSTRACT Glutaminase 1
