Antioxidant effects of potassium ascorbate with ribose in costello syndrome.

Background: Costello syndrome is a rare genetic condition characterized by coarse facies, short stature, loose folds of skin especially on hands and feet, severe feeding difficulties and failure to thrive. Other features include cardiac anomalies, developmental disability and increased risk of neoplasms. Given the link between oxidative stress (OS) and carcinogenesis, we tested the hypothesis that OS occurs in this syndrome, supposing its role both in cancer development and in other clinical features.

Identification of a novel p190-derived breakpoint Peptide suitable for Peptide vaccine therapeutic approach in ph+ acute lymphoblastic leukemia patients.

Ph+ acute lymphoblastic leukemia (Ph+ ALL) is a high-risk acute leukemia with poor prognosis, in which the specific t(9;22)(q34;q11) translocation results in a chimeric bcr-abl (e1a2 breakpoint) and in a 190 KD protein (p190) with constitutive tyrosine kinase activity. The advent of first- and second-generation tyrosine kinase inhibitors (TKIs) improved the short-term outcome of Ph+ ALL patients not eligible for allo-SCT; yet disease recurrence is almost inevitable. Peptides derived from p190-breakpoint area are leukemia-specific antigens that may mediate an antitumor response toward p190+ leukemia cells.

Impressive activity of lenalidomide monotherapy in refractory angioimmunoblastic T-cell lymphoma: report of a case with long-term follow-up.

Angioimmunoblastic T-cell lymphoma (AITL) is characterized by an aggressive clinical course and unfavourable prognosis. Refractory AITL patients have very few treatment options. Lenalidomide has previously been reported to have clinical efficacy in this setting; however, long-term reports are limited.
