Ceramide regulates several different cellular responses including mechanisms leading to apoptosis. Serum- and glucocorticoid-inducible protein kinase (SGK)-1 is a serine threonine kinase, which activates survival pathways in response to stress stimuli. Recently, we demonstrated an anti-apoptotic role of SGK-1 in human umbilical endothelial cells treated(More)
BACKGROUND Colorectal cancer (CRC) infiltration by adaptive immune system cells correlates with favorable prognosis. The role of the innate immune system is still debated. Here we addressed the prognostic impact of CRC infiltration by neutrophil granulocytes (NG). METHODS A TMA including healthy mucosa and clinically annotated CRC specimens (n = 1491) was(More)
The clinical course of colorectal carci-noma (CRC) critically depends on cancer cell-intrinsic features, including specific mutations, microsatellite instability, and epigenetic alterations, as well as on the tumor microenvironment, as shaped by the interaction of malignant and non-transformed cells. Tumor infiltration by cellular components of the adaptive(More)
To study the early stages of development from stem cells of the CD56+ cell population [which includes natural killer (NK) cells], granulocyte-colony stimulating factor-mobilized peripheral blood CD34+ cells from healthy donors were sorted to >99% purity and cultured in the presence of stem cell factor and interleukin (IL)-2. After 3 weeks in culture, the(More)
Tumor associated antigens are useful in colorectal cancer (CRC) management. The ribosomal P proteins (P0, P1, P2) play an important role in protein synthesis and tumor formation. The immunogenicity of the ribosomal P0 protein in head and neck, in breast and prostate cancer patients and the overexpression of the carboxyl-terminal P0 epitope (C-22 P0) in some(More)
Central nervous system (CNS) involvement is identified at the time of diagnosis in less than 10% of adult acute lymphoblastic leukemia (ALL). These patients can attain long-term disease-free survival. CNS disease at presentation does not appear to be an independent poor prognostic factor. Because of the difficulty in treating CNS leukemia, innovative(More)
Acute myeloid leukemia (AML) cells induce, in vitro, NK cell abnormalities (NKCAs) including apoptosis and activating receptor down-regulation. The potential negative impact of AML cells on the therapeutic efficacy of NK cell-based strategies prompted us to analyze the mechanisms underlying NKCAs and to develop approaches to protect NK cells from NKCAs.(More)
In vitro stimulation of CD34+ cells with IL-2 induces NK cell differentiation. In order to define the stages of NK cell development, which influence their generation from CD34 cells, we cultured G-CSF mobilized peripheral blood CD34+ cells in the presence of stem cell factor and IL-2. After three weeks culture we found a diversity of CD56+ subsets which(More)
Pretreatment assessment of cytogenetic/genetic signature of acute myeloid leukemia (AML) has been consistently shown to play a major prognostic role but also to fail at predicting outcome on individual basis, even in low-risk AML. Therefore, we are in need of further accurate methods to refine the patients' risk allocation process, distinguishing more(More)
