T cell receptor for antigen induces linker for activation of T cell-dependent activation of a negative signaling complex involving Dok-2, SHIP-1, and Grb-2

Adaptor proteins positively or negatively regulate the T cell receptor for antigen (TCR) signaling cascade. We report that after TCR stimulation, the inhibitory adaptor downstream of kinase (Dok)-2 and its homologue Dok-1 are involved in a...

Histone Deacetylase 7 Functions as a Key Regulator of Genes Involved in Both Positive and Negative Selection of Thymocytes

Histone deacetylase 7 (HDAC7) is highly expressed in CD4(+)/CD8(+) thymocytes and functions as a signal-dependent repressor of gene transcription during T-cell development. In this study, we expressed HDAC7 mutant proteins in a T-cell line and use...

NF-kappaB is required for STAT-4 expression during dendritic cell maturation

The transcription factor STAT-4 plays a pivotal role in the IL-12-mediated development of naive CD4(+) T cells into the Th1 phenotype. Initially thought to be restricted to the lymphoid lineage, STAT-4 was subsequently shown to be expressed in the...

Cleavage of misfolded nuclear receptor corepressor confers resistance to unfolded protein response-induced apoptosis

We have recently reported that accumulation of misfolded nuclear hormone receptor corepressor (N-CoR) as insoluble protein aggregates in acute promyelocytic leukemia (APL) cells induces endoplasmic reticulum (ER) stress and activates unfolded protein...

X-box-binding protein 1 (XBP-1) activates lytic Epstein-Barr virus gene expression in combination with Protein Kinase D (PKD)

Epstein-Barr virus (EBV) establishes a latent form of infection in memory B cells, while antibody-secreting plasma cells often harbor the lytic form of infection. The switch between latent and lytic EBV infection is mediated by the two viral...

ADAM28 Is Overexpressed in Human Breast Carcinomas: Implications for Carcinoma Cell Proliferation through Cleavage of Insulin-like Growth Factor Binding Protein-3

A disintegrin and metalloproteinases (ADAMs) are involved in various biological events including cell adhesion, cell fusion, membrane protein shedding, and proteolysis. In the present study, our reverse transcription-PCR analysis showed that among...

Activated Cdc42-associated kinase Ack1 promotes prostate cancer progression via androgen receptor tyrosine phosphorylation

Activation of the androgen receptor (AR) may play a role in androgen-independent progression of prostate cancer. Multiple mechanisms of AR activation, including stimulation by tyrosine kinases, have been postulated. We and others have recently shown...

Cyclic adenosine monophosphate is a key component of regulatory T cell-mediated suppression

Naturally occurring regulatory T cells (T reg cells) are a thymus-derived subset of T cells, which are crucial for the maintenance of peripheral tolerance by controlling potentially autoreactive T cells. However, the underlying molecular mechanisms...

Proinsulin is encoded by an RNA splice variant in human blood myeloid cells

Genes for peripheral tissue-restricted self-antigens are expressed in thymic and hematopoietic cells. In thymic medullary epithelial cells, self-antigen expression imposes selection on developing autoreactive T cells and regulates susceptibility to...

Cell adhesion induces p27Kip1-associated cell-cycle arrest through down-regulation of the SCFSkp2 ubiquitin ligase pathway in mantle-cell and other non-Hodgkin B-cell lymphomas

Mounting evidence suggests that dynamic interactions between tumor and its microenvironment play a critical role in tumor development, cell cycle progression and response to therapy. In this study we used mantle cell lymphoma (MCL) as a model to...
