Morphoproteomics identifies constitutive activation of the mTORC2/Akt and NF-κB pathways and expressions of IGF-1R, Sirt1, COX-2, and FASN in peripheral T-cell lymphomas: pathogenetic implications and therapeutic options.

Background: Gaining a better understanding of the molecular circuitries and pathways implicated in the malignant growth and biological behavior of T cell lymphomas may identify potential cellular targets with clinical therapeutic potential. The immunohistochemical characterization of key cellular proteins participating in these pathways can provide surrogate markers of biological activity. The mammalian target of rapamycin complex (mTORC) signaling pathway has been implicated in T-cell lymphopoiesis.
