      Caveolin-1 is suggested to act as a tumor suppressor. We tested the hypothesis that caveolin-1 does so by repression of survivin, an Inhibitor of apoptosis protein that regulates cell-cycle progression as well as apoptosis ...
    • Simón, L.; Campos González, América; Leyton Campos, Lisette; Quest, Andrew F. G. (Springer, 2020)
      Caveolin-1 (CAV1) is commonly considered to function as a cell surface protein, for instance in the genesis of caveolae. Nonetheless, it is also present in many intracellular organelles and compartments. The contributions ...

G. (Lippincott Williams & Wilkins, 2014)
      Melanomas are highly lethal skin tumours that are frequently treated by surgical resection. However, the efficacy of such procedures is often limited by tumour recurrence and metastasis. Caveolin-1 (CAV1) has been ...
    • Rodríguez, Diego A.; Tapia, Julio; Fernández, Jaime G.; Torres Gómez, Vicente; Muñoz, Nicolás; Galleguillos, Daniela; Leyton Campos, Lisette; Quest, Andrew F. G. (2009)
      Augmented expression of cyclooxygenase-2 (COX-2) and enhanced production of prostaglandin E2 (PGE2) are associated with increased tumor cell survival and malignancy. Caveolin-1 is a scaffold protein that has been proposed ...

      Caveolin-1 (CAV1) is a well-established nitric oxide synthase inhibitor, whose function as a tumor suppressor is favored by, but not entirely dependent on, the presence of E-cadherin. Tumors are frequently hypoxic and the ...
    • Sanhueza Muñoz, Carlos Joaquín (Universidad de Chile, 2013)
      El cáncer es la 2° causa de muerte en Chile. El desarrollo del cáncer se ha propuesto que es consecuencia de la pérdida de función de los genes supresores de tumores beneficiando la acción de los oncogenes (genes que ...
    • Hermosilla, Tamara; Muñoz, Daniel; Herrera Molina, Rodrigo; Valdivia, Alejandra; Muñoz, Nicolás; Nham, Sang-Uk; Schneider, Pascal; Burridge, Keith; Quest, Andrew F. G.; Leyton Campos, Lisette (ELSEVIER, 2008-06)
      Thy-1 is an abundant neuronal glycoprotein of poorly defined function. We recently provided evidence indicating that Thy-1 clusters a beta(3)-containing integrin in astrocytes to induce tyrosine phosphorylation, RhoA ...
