PI3K
PI3K signaling regulates cellular function by linking growth factors, GPCRs, and oncogene products to intracellular lipid signaling[1]. Mechanistically, class I PI3K isoforms generate PIP3, a second messenger that controls cell movement, growth, survival, and differentiation[2][3]. Therefore, PI3K biology provides a practical framework for studying metabolism, immune-system function, cancer, and inflammation[1][2]. In disease-focused models, PI3K pathway activation supports cancer-cell growth, survival, motility, and metabolism, making pathway inhibition relevant for genetically and clinically defined cancers[2]. Compared with related isoforms, PI3Kα inhibition is most effective in cancers with genetic activation of this isoform, whereas PI3Kδ inhibition acts mainly through B-cell antigen receptor signaling and tumor-stroma interactions[4]. PI3Kδ and PI3Kγ also function prominently in leukocytes, and dual blockade with IPI-145 suppressed immune responses in autoimmune and inflammatory disease models[5]. For experimental applications, IPI-145 inhibited PI3K/AKT/S6 signaling, reduced CLL-cell chemokine secretion and chemotaxis, and promoted apoptosis in BCR-stimulated or stromal co-cultured primary CLL cells[6].
