p65 is a member of the NF-κB family of transcriptional regulatory proteins that functions as the activating component of the p65-p50 heterodimer. Through its acidic transactivation domain (TAD), p65 has the capacity to form interactions with several different transcriptional regulatory proteins, including TFIIB, TFIIH, CREB-binding protein (CBP)/p300 and TAFII31. Like other acidic TADs, the p65 TAD contains two subdomains (p65TA1 and p65TA2) that interact with different regulatory factors depending on the target gene...

Since liposome-encapsulated hemoglobin with high O2 affinity (h-LEH, P50 O2  = 10 mm Hg) has been reported to accelerate skin wound healing in normal mice, it was tested in dB/dB mice with retarded wound healing, as seen in human diabetics. Two full-thickness dorsal wounds 6 mm in diameter encompassed by silicone stents were created in dB/dB mice. Two days later (day 2), the animals were randomly assigned to receive intravenous h-LEH (2 mL/kg, n = 7) or saline (2 mL/kg, n = 7). The same treatment was repeated 4 days after wounding (day 4), and the size of the skin lesions was analyzed by photography, surface perfusion was detected by Laser-Doppler imager, and plasma cytokines and chemokines were determined on days 0, 2, 4, and 7, when all animals were euthanized for morphological studies...

Sepsis-typically caused by an uncontrolled and amplified host systemic inflammatory response to microbial infection-is a life-threatening complex clinical disorder and remains a major cause of infection-related deaths in the intensive care unit. Emerging evidence suggests that neuropilin 1 (Nrp1), an originally defined coreceptor for class 3 semaphorins and VEGF, plays important roles in the immune system; however, the function and regulation of macrophage Nrp1 in host immune defense against bacterial infection remain unknown...

The development of a blood substitute is urgent due to blood shortages and potential communicable diseases. A novel method, inside-out PEGylation, has been used here to conjugate a multiarm maleimide-PEG (Mal-PEG) to β-cross-linked (βXL-Hb) hemoglobin (Hb) tetramers through the Cys β93 residues. This method produces a polymer with a single PEG backbone that is surrounded by multiple proteins, rather than coating a single protein with multiple PEG chains. Electrophoresis under denaturing conditions showed a large molecular weight species...

Torilin, a sesquiterpene isolated from the fruits of Torilis japonica, has shown antimicrobial, anticancer, and anti-inflammatory properties. However, data on the mechanism of torilin action against inflammation is limited. This study aimed at determining the anti-inflammatory property of torilin in LPS-induced inflammation using in vitro model of inflammation. We examined torilin's effect on expression levels of inflammatory mediators and cytokines in LPS-stimulated RAW 264.7 macrophages. The involvement of NF-kB and AP-1, MAP kinases, and adaptor proteins were assessed...

BACKGROUND: Obstetrics and gynecology departments receive the smallest amount of National Institutes of Health (NIH) research funding and have significantly lower application success rates compared to pediatric, internal medicine, and surgery departments. The development of mentored early career development training grants (K awards) has been one strategy implemented by the NIH to help aspiring physician-scientists establish independent research careers. OBJECTIVE: The purpose of this study is to describe the cohort of ob/gyn physician-scientists who were K08, K12, and K23 recipients from 1988-2015 and to identify predictors of success in obtaining independent federal funding, as defined by acquisition of an R01, R21, R34, U01, U54, P01, or P50...

Catalase is well-known as an antioxidant dismutating H2O2 to O2 and H2O. However, catalases evolved when metabolism was largely sulfur-based, long before O2 and reactive oxygen species (ROS) became abundant, suggesting catalase metabolizes reactive sulfide species (RSS). Here we examine catalase metabolism of H2Sn, the sulfur analog of H2O2, hydrogen sulfide (H2S) and other sulfur-bearing molecules using H2S-specific amperometric electrodes and fluorophores to measure polysulfides (H2Sn; SSP4) and ROS (dichlorofluorescein, DCF)...

Dysregulated NF-κB signaling is critical for lymphomagenesis, however, the expression and clinical relevance of NF-κB subunit p50 in diffuse large B-cell lymphoma have not been evaluated. In this study, we analyzed the prognostic significance and gene expression signatures of p50 nuclear expression as a surrogate for p50 activation in 465 patients with de novo diffuse large B-cell lymphoma. We found that p50(+) nuclear expression, observed in 34.6% of diffuse large B-cell lymphoma, predominantly composed of activated B-cell-like subtype, was an independent adverse prognostic factor in patients with activated B-cell-like diffuse large B-cell lymphoma...

The IκBζ protein (NFKBIZ gene) is a nuclear inhibitor of NF-κB and plays an important role in the pathogenesis of Psoriasis (Psor). We sought to determine whether common NFKBIZ variants were associated with the risk of developing Psor. A total of 392 patients and 336 controls were genotyped for a common intron 10 indel that could affect pre-mRNA splicing. We found a significantly higher frequency of the insertion among the cw6-positive patients (p=0.01). Cw6-positive+intron 10 ins/ins were significantly more frequent in the patients (OR=3...

Diffuse large B-cell lymphoma (DLBCL) is the most common B-cell lymphoma subtypes, and the Epstein-Barr virus (EBV)-positive subtype of DLBCL is known to exhibit a more aggressive clinical behavior than the EBV-negative one. BTB and CNC homology 2 (BACH2) has been highlighted as a tumor suppressor in hematopoietic malignancies; however, the role of BACH2 in EBV-positive DLBCL is unclear. In the present study, BACH2 expression and its significance were studied in 23 EBV-positive and 43 EBV-negative patient samples...

We recently discovered that IκBα enhances the rate of release of nuclear factor kappa B (NFκB) from DNA target sites in a process we have termed molecular stripping. Coarse-grained molecular dynamics simulations of the stripping pathway revealed two mechanisms for the enhanced release rate: the negatively charged PEST region of IκBα electrostatically repels the DNA, and the binding of IκBα appears to twist the NFκB heterodimer so that the DNA can no longer bind. Here, we report amide hydrogen/deuterium exchange data that reveal long-range allosteric changes in the NFκB (RelA-p50) heterodimer induced by DNA or IκBα binding...

Anemia is associated with chemotherapy treatment in cancer patients. Erythropoietin (EPO) has been used to treat anemia of cancer patients, because it stimulates erythropoiesis. However, treatment of breast cancer patients with EPO has been associated with poor prognosis and decrease of survival. Epithelial to mesenchymal transition (EMT) is a process by which epithelial cells are transdifferentiated to a mesenchymal state. It has been implicated in tumor progression, because epithelial cells acquire the capacity to execute the multiple steps of invasion/metastasis process...

NF-κB is a critical transcription factor that plays an important role in mediating inflammation, the immune response, and cell proliferation. The activation of NF-κB leads to an enhancement of proinflammatory mediator expression, which is implicated in the pathogenesis of a variety of diseases. Therefore, methods that allow the intracellular tracking of NF-κB are particularly attractive because they can provide information regarding the pathways or stimulation responses that are involved in the activation of NF-κB...

Defects in p53 and nuclear factor-kappa B (NF-κB) signaling pathways are frequently observed in the initiation and development of various human malignancies, including prostate cancer. Clinical studies demonstrate higher expression of NF-κB/p65/RelA, NF-κB/p50/RelB, and cRel as well as downregulation of the p53 network in primary prostate cancer specimens and in metastatic tumors. Betulinic acid (BA), is a triterpenoid that has been reported to be an effective inducer of apoptosis through modification of several signaling pathways...
