Resistance to asparaginase, an antileukemic enzyme that depletes asparagine, is a common clinical problem. Using a genome-wide CRISPR/Cas9 screen, we found a synthetic lethal interaction between Wnt pathway activation and asparaginase in acute leukemias resistant to this enzyme. Wnt pathway activa...

These assays represent antibody-binding assays to analyze seroprevalence of antigens and epitopes at the individual level and also to perform fine epitope mapping characterizations. In this screening 392,299 peptides derived from reactive (antigenic) regions of Trypanosoma cruzi proteins were displa...

These assays represent an antigen discovery screening, and epitope mapping characterization. In this screening two complete proteomes from Trypanosoma cruzi, from two different strains (CL-Brener, Sylvio X10), were displayed in the form of short peptides (tiling array, overlapped) and assayed with p...

The goals of this study are to unravel the molecular mechanisms underlying leukemic transformation and chemotherapy resistance in T-cell acute lymphoblastic leukemia (T-ALL). Towards this end, a cohort of T-ALL lymphoblast specimens was collected at the time of initial T-ALL diagnosis (prior to t...

Cyclin C was cloned as a growth-promoting G1 cyclin1,2, and several studies postulated a role for cyclin C in driving cell proliferation3-8 . Moreover, cyclin C, together with its kinase partner, the cyclin-dependent kinase CDK8, is believed to represent an essential component of basal transcrip...

We have shown that drug-resistant leukemias rely on protein degradation through the ubiquitin proteasome pathway to survive during asparaginase therapy. Our studies support the model that this catabolic source of amino acids is upregulated in response to amino acid starvation. To investigate wheth...
