BACKGROUND: Women with higher serum calcium may be more likely to be diagnosed and die of ovarian cancer. We evaluated that finding in a large, prospective cohort. METHODS: We conducted a nested case-control study using a population-based biobank from Norway. We compared 202 ovarian cancer cases and 202 controls, matched for age, date at blood draw, and county of residence, with respect to serum calcium and albumin, adjusted for anthropometric variables. We evaluated risks using the entire follow-up period as well as 2-15 years and 16-25 years ("early" and "late", respectively)...

Proviral insertion in murine (PIM) lymphoma proteins are mainly regulated by the Janus Kinase/Signal Transducer Activator of Transcription (JAK/STAT) signaling pathway, which can be activated by members of the Interleukin-6 (IL-6) family, including Leukemia Inhibitory Factor (LIF). Aim of the study was to compare PIM1, PIM2 and PIM3 expression and potential cellular functions in human first and third trimester trophoblast cells, the immortalized first trimester extravillous trophoblast cell line HTR8/SVneo and the choriocarcinoma cell line JEG-3...

Donor-acceptor dyads hold the key to tuning of electrochemical properties and enhanced mobility of charge carriers, yet their incorporation into a heterogeneous polymer network proves difficulty due to the fundamentally different chemistry of the donor- and acceptor-subunits. We present a family of sulphur and nitrogen containing porous polymers (SNPs) that are obtained via Sonogashira-Hagihara cross-coupling and that combine electron-withdrawing triazine (C3N3) and electron donating, sulphur-containing linkers...

Current diagnostic criteria for Philadelphia-negative myeloproliferative neoplasia (MPN) have been redefined by the discovery of Janus kinase 2 (JAK2), myeloproliferative leukemia (MPL) and calreticulin (CALR) genetic alterations. Only few cases of coexistence of CALR-mutated MPN and Philadelphia-positive chronic myeloid leukemia (CML) have been described so far. Here we report the case of a patient with CML diagnosed in 2001, treated with imatinib and pegylated interferon (IFN) frontline. She reached complete molecular remission (CMR) and discontinued imatinib, maintaining treatment free remission...

In chronic lymphocytic leukemia (CLL) cells, both interleukin-6 (IL-6) and the B-cell receptor (BCR) activate Janus kinase 2 (JAK2) and induce the phosphorylation of signal transduction and activator of transcription 3 (STAT3) on tyrosine 705 residues. However, whereas IL-6 phosphorylates STAT3 within 15 minutes, stimulation of the BCR with anti-immunoglobulin M (IgM) antibodies phosphorylates STAT3 in 2-4 hours. Here we show that this process takes longer because it requires transcriptional activity of NF-κB...

A series of atypical asymmetric gemini surfactants with an amphiphilic carbonate group (-O-CO-O-) have been prepared. Some of these compounds could self-assemble in water into gourd-shaped Janus particles (JPs). Initial results suggested that the formation of JPs was highly likely to be related to their atypical gemini surfactant structure. To our knowledge, this is the first report on JPs that are self-assembled from a single kind of small organic molecule. We believe that our results will be utilized in many fields...

We present the case of a 79-year-old man who showed multiple pulmonary nodules on chest computed tomography (CT) after being treated for 6 months with ruxolitinib, an inhibitor of Janus kinase (JAK) 1 and 2, to treat primary myelofibrosis. We examined the lesions by bronchoscopy, and the biopsy specimen revealed fungus bodies of Cryptococcus with granulomatous inflammation. As a result, the patient was diagnosed with pulmonary cryptococcosis. The patient was treated with fluconazole (200 mg daily for 2 weeks) with concomitant ruxolitinib administration, but the pulmonary lesions progressed...

AbstractMalaria-endemic countries have to decide how much of their limited resources for vector control to allocate toward implementing long-lasting insecticidal nets (LLINs) versus indoor residual spraying (IRS). To help the Mozambique Ministry of Health use an evidence-based approach to determine funding allocation toward various malaria control strategies, the Global Fund convened the Mozambique Modeling Working Group which then used JANUS, a software platform that includes integrated computational economic, operational, and clinical outcome models that can link with different transmission models (in this case, OpenMalaria) to determine the economic value of vector control strategies...

Alopecia areata is a common hair loss condition that is characterized by acute onset of non-scarring hair loss in usually sharply defined areas ranging from small patches to extensive or less frequently diffuse involvement. Depending on its acuity and extent, hair loss is an important cause of anxiety and disability. The current understanding is that the condition represents an organ-specific autoimmune disease of the hair follicle with a genetic background. Genome-wide association studies provide evidence for the involvement of both innate and acquired immunity in the pathogenesis, and mechanistic studies in mouse models of alopecia areata have specifically implicated an IFN-γ-driven immune response, including IFNγ, IFNγ-induced chemokines and cytotoxic CD8 T cells as the main drivers of disease pathogenesis...

Induction of interferon and proinflammatory cytokines is a hallmark of the infection of many different viruses. However, hepatitis B virus (HBV) does not elicit a detectable cytokine response in infected hepatocytes. In order to investigate the molecular mechanism underlying the innate immune evasion, a functional cGAS-STING pathway was reconstituted in a human hepatoma cell line supporting tetracycline-inducible HBV replication. It was demonstrated that induction of HBV replication neither activated nor inhibited this cytosolic DNA sensing pathway...

Cytokines are key modulators of immunity. Most cytokines use the Janus kinase and signal transducers and activators of transcription (JAK-STAT) pathway to promote gene transcriptional regulation, but their signals must be attenuated by multiple mechanisms. These include the suppressors of cytokine signaling (SOCS) family of proteins, which represent a main negative regulation mechanism for the JAK-STAT pathway. Cytokine-inducible Src homology 2 (SH2)-containing protein (CIS), SOCS1, and SOCS3 proteins regulate cytokine signals that control the polarization of CD4(+) T cells and the maturation of CD8(+) T cells...

Highly anisometric nanoparticles have distinctive mechanical, electrical, and thermal properties and are therefore appealing candidates for use as self-assembly building blocks. Here we demonstrate that ultra-anisometric nanoplates, which have a nanoscale thickness but a micrometer-scale edge length, offer many materials design capabilities. In particular, we show that these nanoplates "copolymerize" in a predictable way with patchy spheres into one- and two-dimensional structures with tunable architectural properties...

Protein phosphorylation, mediated by protein kinases, has important physiological and pathological implications in our lives . Targeting kinase is one of the most interesting of the emerging topics in the pharmaceutical industry, especially since there is a focus on cancer therapy. Given that kinases may be involved in the aging process the focus will be on using the kinase inhibitor for anti-aging intervention to enhance healthspan and increase longevity. In this review , we will summarize: (i) the impact of the phosphoproteomic approach to elucidate molecular mechanisms of diseases; (ii) importance of the drug discovery approach for targeting kinases; (iii) the dysregulation of Janus kinase (JAK) / signal-transducing adapter molecules (STAT) and p70 ribosomal protein S6 kinase (S6Ks) pathway in aging and the age-related process; (iv) the epidemiological studies available in order to see whether a correlation between JAK/STAT and S6Ks mRNA expression levels exist in cancer and in patient outcome; (v) finally, we will show selected inhibitors of these kinases approved by the US Food and Drug Administration (FDA)...

The diffusion of a Janus rod-shaped nanoparticle in a dense Lennard-Jones fluid is studied using molecular dynamics (MD) simulations. The Janus particle is modeled as a rigid cylinder whose atoms at each end have different interaction energies with fluid molecules, thus comprising wetting and nonwetting surfaces. We found that both rotational and translational diffusion coefficients are larger for Janus particles with lower average wettability, and these values are bound between the two limiting cases of uniformly wetting and nonwetting particles...

Tofacitinib is an oral Janus kinase inhibitor. These post-hoc analyses assessed tofacitinib efficacy and safety in Japanese patients with psoriasis enrolled in a 52-week global phase 3 study. Patients received tofacitinib 5 mg, tofacitinib 10 mg or placebo twice daily (b.i.d.); placebo-treated patients advanced to tofacitinib at week 16. Primary efficacy end-points were the proportions of patients with 75% or more reduction from baseline Psoriasis Area and Severity Index (PASI-75) and Physician's Global Assessment (PGA) of "clear" or "almost clear" (PGA response) at week 16...

Previous studies have suggested that the Janus kinase (JAK)/signal transducers and activators of transcription (STAT) pathway is involved in hyperglycemia‑induced lung injury. The present study aimed to investigate the roles of suppressor of cytokine signaling3 (SOCS3) in the regulation of JAK2/STAT3 activation following high glucose (HG) treatment in A549 human pulmonary epithelial cells. Cell viability was evaluated using Cell Counting Kit-8 and lactate dehydrogenase assays. HG‑induced inflammatory injury in A549 cells was assessed through the evaluation of interleukin‑6 (IL‑6) and tumor necrosis factor‑α (TNF‑α) levels using ELISA...

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and Ulcerative Colitis (UC), are immune mediated conditions associated with progressive damage of the inflamed gut tissue, and have a considerable impact on the patient's quality of life. The pathogenesis remains uncertain, but it is clear that complex mechanisms associated with host and luminal factors are involved, generating an unbalance between pro- and anti-inflammatory signaling. It is well established that the purpose of an adequate and complete control of the intestinal inflammation measured not only by clinical symptoms, but also with more objective data such as fecal biomarkers (calprotectin) and endoscopy...

The pathogenesis of atopic dermatitis (AD) involves epidermal barrier dysfunction and T helper cell type 2 (Th2) lymphocyte-driven inflammation. Cytokines, such as interleukin 4 (IL-4) and IL-13, are important in this reaction. They stimulate B cells to produce immunoglobulin E, causing atopic disease. This process has been well characterized, and new therapies for AD, such as phosphodiesterase 4 (PDE-4) inhibitors, Th2-expressed chemoattractant receptor-homologous molecule antagonists, and Janus kinase inhibitors, work by antagonizing this cellular pathway...
