Activating mutations of PIK3CA are the most frequent genomic alterations in estrogen receptor (ER)-positive breast tumors and selective PI3Kα inhibitors are in clinical development. The activity of these agents, however, is not homogenous and only a fraction of patients bearing PIK3CA-mutant ER-posi...

Hybrids between species contain a mixture of two divergent proteomes, the combination of which may lead to dysfunctional protein-protein interactions. We performed an integrative study on hybrids between the swordtail fishes Xiphophorus malinche and Xiphophorus birchmanni, and found that the combina...

Although information on the molecular pathogenesis of Waldenström’s Macroglobulinemia (WM) has greatly improved in recent years, the exact cellular origin and the mechanisms behind WM transformation from IgM MGUS remain undetermined. Here, we undertook an integrative phenotypic, molecular and genomi...

Despite their long half-life, therapeutic antibodies are considered ineffective against intracellular antigens due to their perceived inability to penetrate epithelial cells. Using recombinant antibodies targeting common mutations in oncogenes, we demonstrate that dimeric IgA, but not the same antib...
