    • Association of PALB2 sequence variants with the risk of familial and early-onset breast cancer in a ... 
      Leyton, Yessica; González Hormazábal, Patricio; Blanco Castillo, Rafael; Bravo, Teresa; Fernández Ramires, Ricardo; Morales, Sebastián; Landeros, Natalia; Reyes, José M.; Peralta Musre, Octavio; Tapia, Julio C.; Gómez, Fernando; Waugh, Enrique; Ibáñez, Gladys; Pakomio, Janara; Grau, Gilberto; Jara Sosa, Lilian (BioMed Central, 2015)
      Background Germline mutations in PALB2 have been identified in approximately 1% of familial breast cancer (BC) in several populations. Nevertheless its contribution in the South-American population is unknown. The goal ...
    • CK2 functionally interacts with AKT/PKB to promote the β-catenin- dependent expression of survivin and ... 
      Ponce, Daniela P.; Yefi, Roger; Cabello, Pablo; Maturana, Jose L.; Niechi, Ignacio; Silva, Eduardo; Galindo, Mario; Antonelli, Marcelo; Marcelain Cubillos, Katherine; Armisen Yáñez, Ricardo; Tapia, Julio C. (2011)
      β-Catenin is crucial in the canonical Wnt signaling pathway. This pathway is up-regulated by CK2 which is associated with an enhanced expression of the antiapoptotic protein survivin, although the underlying molecular ...
    • Identification of Ski as a target for Aurora A kinase 
      Mosquera, Jocelyn; Armisen Yáñez, Ricardo; Zhao, Hongling; Rojas, Diego A.; Maldonado, Edio; Tapia, Julio C.; Colombo, Alicia; Hayman, Michael J.; Marcelain Cubillos, Katherine (2011)
      Ski is a negative regulator of the transforming growth factor-β and other signalling pathways. The absence of SKI in mouse fibroblasts leads to chromosome segregation defects and genomic instability, suggesting a role for ...
    • Neuronal Thy-1 induces astrocyte adhesion by engaging syndecan-4 in a cooperative interaction with αvβ3 ... 
      Avalos, Ana María; Valdivia, Alejandra D.; Muñoz, Nicolás; Herrera Molina, Rodrigo; Tapia, Julio C.; Lavandero González, Sergio; Chiong Lay, Mario; Burridge, Keith; Schneider, Pascal; Quest, Andrew F. G.; Leyton Campos, Lisette (2009)
      Clustering of αvβ3 integrin after interaction with the RGD-like integrin-binding sequence present in neuronal Thy-1 triggers formation of focal adhesions and stress fibers in astrocytes via RhoA activation. A putative ...
    • Phosphorylation of AKT/PKB by CK2 is necessary for the AKT-dependent up-regulation of β-catenin transcriptional ... 
      Ponce, Daniela P.; Maturana, Jose L.; Cabello, Pablo; Yefi, Roger; Niechi, Ignacio; Silva, Eduardo; Armisen Yáñez, Ricardo; Galindo, Mario; Antonelli, Marcelo; Tapia, Julio C. (2011)
      β-Catenin is a key protein in the canonical Wnt signaling pathway and in many cancers alterations in transcriptional activity of its components are observed. This pathway is up-regulated by the protein kinase CK2, but the ...
    • Protein kinase CK2 promotes cancer cell viability via up-regulation of cyclooxygenase-2 expression and ... 
      Yefi, Roger; Ponce, Daniela P.; Niechi, Ignacio; Silva, Eduardo; Cabello, Pablo; Rodriguez, Diego A.; Marcelain Cubillos, Katherine; Armisen Yáñez, Ricardo; Quest, Andrew F. G.; Tapia, Julio C. (2011)
      Augmented expression of protein kinase CK2 is associated with hyperproliferation and resistance to apoptosis in cancer cells. Effects of CK2 are at least partially linked to signaling via the Wnt/β-catenin pathway, which ...
    • The Ski Protein is Involved in the Transformation Pathway of Aurora Kinase A 
      Rivas, Solange; Armisen Yáñez, Ricardo; Rojas, Diego A.; Maldonado Maldonado, Edio; Huerta, Hernán; Tapia, Julio C.; Espinoza, Jaime; Colombo, Alicia; Michea Acevedo, Luis; Hayman, Michael J.; Marcelain Cubillos, Katherine (Wiley & Sons, 2016)
      Oncogenic kinase Aurora A (AURKA) has been found to be overexpresed in several tumors including colorectal, breast, and hematological cancers. Overexpression of AURKA induces centrosome amplification and aneuploidy and it ...
    • TRPM4 enhances cell proliferation through up-regulation of the β-catenin signaling pathway 
      Armisen Yáñez, Ricardo; Marcelain Cubillos, Katherine; Simon, Felipe; Tapia, Julio C.; Toro, Jessica; Quest, Andrew F. G.; Stutzin Schottlander, Andrés (2011)
      Altered expression of some members of the TRP ion channel superfamily has been associated with the development of pathologies like cancer. In particular, TRPM4 levels are reportedly elevated in diffuse large B-cell non-Hodgkin ...
    • TRPM4 regulates Akt/GSK3-b activity and enhances b-catenin signaling and cell proliferation in prostate ... 
      Sagredo, A.; Sagredo, Eduardo A.; Cappelli, Claudio; Baez, Pablo; Andaur, Rodrigo E.; Blanco, Constanza; Tapia, Julio C.; Echeverría, César; Cerda, Oscar; Stutzin Schottlander, Andrés; Simon, Felipe; Marcelain Cubillos, Katherine; Armisen Yáñez, Ricardo (John Wiley, 2018)
      Increased expression of the TRPM4 channel has been reported to be associated with the progression of prostate cancer. However, the molecular mechanism underlying its effect remains unknown. This work found that decreasing ...
