PED Mediates AKT-Dependent Chemoresistance in Human Breast Cancer Cells

2005

Abstract Killing of tumor cells by cytotoxic therapies, such as chemotherapy or gamma-irradiation, is predominantly mediated by the activation of apoptotic pathways. Refractoriness to anticancer therapy is often due to a failure in the apoptotic pathway. The mechanisms that control the balance between survival and cell death in cancer cells are still largely unknown. Tumor cells have been shown to evade death signals through an increase in the expression of antiapoptotic molecules or loss of proapoptotic factors. We aimed to study the involvement of PED, a molecule with a broad antiapoptotic action, in human breast cancer cell resistance to chemotherapeutic drugs–induced cell death. We show…

PTEN hamartoma tumor syndromes in childhood: description of two cases and a proposal for follow-up protocol

2013

PTEN hamartoma tumor syndromes (PHTS) are a spectrum of hamartomatous overgrowth syndromes associated with germ-line mutations in the tumor suppressor PTEN gene located on 10q23.3. It is widely accepted that two of these disorders, Cowden syndrome and Bannayan-Riley-Ruvalcaba syndrome, are allelic conditions. Because PTEN mutations are not identifiable in every case of the PHTS phenotype, the inability to detect a mutation within the PTEN gene does not invalidate the clinical diagnosis of Cowden syndrome, or Bannayan-Riley-Ruvalcaba syndrome, in patients who meet diagnostic criteria for these disorders. PTEN mutations are associated with an increased risk for developing breast, thyroid, end…
