Research ArticleFra-2 Expression in Osteoblasts Regulates Systemic Inflammation and Lung Injury through OsteopontinInflammatory responses require mobilization of innate immune cells from the bone marrow. The functionality of this process depends on the state of the bone marrow microenvironment.
Research ArticleProtein Phosphatase 1α and Cofilin Regulate Nuclear Translocation of NF-κB and Promote Expression of the Anti-Inflammatory Cytokine Interleukin-10 by T CellsWhile several protein serine/threonine kinases control cytokine production by T cells, the roles of serine/threonine phosphatases are largely unexplored. Here, we analyzed the involvement of protein phosphatase 1α (PP1α) in cytokine synthesis following costimulation of primary human T cells.
Research ArticleThe C9ORF72 Gene, Implicated in Amyotrophic Lateral Sclerosis and Frontotemporal Dementia, Encodes a Protein That Functions in Control of Endothelin and Glutamate SignalingA GGGGCC repeat expansion in the C9ORF72 (C9) gene is the most common known cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia. Several mechanisms have been proposed to account for its toxicity, including the possibility that reduced C9 protein levels contribute to disease.
Research ArticleRegulation of Transcription Factor SP1 by the β-Catenin Destruction Complex Modulates Wnt ResponseThe ubiquitous transcription factor specificity protein 1 (SP1) is heavily modified posttranslationally. These modifications are critical for switching its functions and modulation of its transcriptional activity and DNA binding and stability.
Research Article | SpotlightTransient Overexpression of Vascular Endothelial Growth Factor A in Adipose Tissue Promotes Energy Expenditure via Activation of the Sympathetic Nervous SystemAdipose-derived vascular endothelial growth factor A (VEGF-A) stimulates functional blood vessel formation in obese fat pads, which in turn facilitates healthy expansion of the adipose tissue. However, the detailed mechanism(s) governing the process remains largely unknown.
Research ArticleMyc-Associated Zinc Finger Protein Regulates the Proinflammatory Response in Colitis and Colon Cancer via STAT3 SignalingMyc-associated zinc finger (MAZ) is a transcription factor highly upregulated in chronic inflammatory disease and several human cancers. In the present study, we found that MAZ protein is highly expressed in human ulcerative colitis and colon cancer.
Research Article | Spotlightp62-Dependent Phase Separation of Patient-Derived KEAP1 Mutations and NRF2Cancer-derived loss-of-function mutations in the KEAP1 tumor suppressor gene stabilize the NRF2 transcription factor, resulting in a prosurvival gene expression program that alters cellular metabolism and neutralizes oxidative stress. In a recent genotype-phenotype study, we classified 40% of KEAP1 mutations as ANCHOR mutants.
