RATIONALE: Primary myelofibrosis is encountered with the myeloproliferative diseases and is the least prevalent among women of childbearing age. The prognosis is guided by pancytopenia, leukemic transformation and thrombosis which are the dominant complications. PATIENT CONCERNS: Data regarding protocol management during pregnancy in the context of myelofibrosis are insufficient. Fewer than ten cases have been described until now and half of this cases have resulted in fetal death due to placental infarction during the second and third trimesters...

The classical BCR-ABL1-negative myeloproliferative neoplasms (MPN) include primary myelofibrosis (PMF), polycythaemia vera (PV) and essential thrombocythaemia (ET). They are characterized by stem cell-derived clonal proliferation, harbour Janus kinase 2 (JAK2), or calreticulin (CALR), or myeloproliferative leukaemia virus oncogene (MPL) driver mutations and exert an over activated JAK-signal transducer and activator of transcription (STAT) pathway. Therefore JAK inhibiting strategies have been successfully investigated in MPN clinical trials...

BACKGROUND/AIMS: Vascular endothelial growth factor (VEGF) has been demonstrated to play a pivotal role in the regulation of angiogenesis in ovarian follicular development, particularly during the preovulatory period. Although numerous studies have shown that interleukin-6 (IL-6) is one of the major inducing factors that regulate the expression of VEGF in non-ovarian cells, whether it involved in regulating the expression of VEGF in normal ovarian granulosa cells is still unknown. The aim of this study was to elucidate the mechanisms underlying the effect of IL-6 on FSH-induced VEGF expression in bovine granulosa cells derived from large follicles...

Myelofibrosis (MF) is a clonal neoplasia associated with chronic inflammation due to aberrant cytokine production. Mutations in Janus Kinase-2 (JAK2), calreticulin (CALR) and myeloproliferative leukemia protein (MPL) genes have been recently associated to MF and they all activate the JAK/STAT signaling pathway. Since this pathway is essential in shaping the immune response, we investigated the role of circulating immune subsets and cytokines in 38 patients (20 carrying JAK2((V617F)),13 exon-9 CALR mutation and 5 triple negative)...

Immune evasion is a well-recognized hallmark of cancer and recent studies with immunotherapy agents have suggested that tumors with increased numbers of neoantigens elicit greater immune responses. We hypothesized that the immune system presents a common selective pressure on high mutation burden tumors and therefore immune evasion mutations would be enriched in high mutation burden tumors. The JAK family of kinases is required for the signaling of a host of immune modulators in tumor, stromal, and immune cells...

BACKGROUND: The Janus Kinase (JAK) and Signal Transducer and Activator of Transcription (STAT) pathways play important roles in the pathogenesis of diffuse large B cell lymphoma (DLBCL) in humans, and up-regulated STAT3 expression and activity are associated with worse clinical outcome in humans. No studies have evaluated the JAK-STAT signaling pathway in DLBCL of dogs. HYPOTHESIS: STAT3 pathway is deregulated in DLBCL in dogs. We aim to assess the expression, activation, and cellular localization of STAT3 and mitogen-activated protein kinase ERK1/2 in DLBCL of dogs...

Significant advances in the understanding of the molecular basis of innate immunity have led to the identification of interferons (IFNs), particularly IFN-α, as central mediators in the pathogenesis of Systemic Lupus Erythematosus. Therefore, targeting of IFNs and of their downstream pathways has emerged as important developments for novel drug research in SLE. Based on this, several specific interferon blocking strategies using anti-IFN-α antibodies, anti-type I interferon receptor antibodies, Interferon-α-kinoid, or anti-IFN-γ antibodies have all been assessed in recent clinical trials...

The pathogenesis and cellular origin of Langerhans cell histiocytosis (LCH) are debated. Recently, mutations on MAPK and PI3K pathways have been linked to disrupted cell proliferation in LCH. Janus Kinase 2 (JAK2) mutations play the same role in Philadelphia-negative chronic myeloproliferative neoplasms. We describe the case of a patient affected by JAK2-positive Primary Myelofibrosis (PMF) who developed a clonally related LCH while in treatment with Ruxolitinib. JAK-inhibitors are well known to affect function and differentiation of different hematological lineages, including mononuclear phagocytes precursors...

The saponin ginsenoside Rk1 is a major compound isolated from ginseng. Ginsenoside Rk1 has been reported to have anti-inflammatory and anti-tumor properties and to be involved in the regulation of metabolism. However, the effect and mechanism of anti-inflammatory action of ginsenoside Rk1 has not been fully clarified. We investigated whether ginsenoside Rk1 could suppress the inflammatory response in lipopolysaccharide-stimulated RAW264.7 macrophages and to explore its mechanism of the action. RAW264.7 cells were treated with LPS (1 μg·mL(-1)) in the absence or the presence of Ginsenoside Rk1 (10, 20, and 40 μmol·L(-1))...

Jumonji (Jmj)/Jarid2 is a DNA-binding transcriptional repressor mediated via histone methylation. Nevertheless, the well-known function of Jmj is as a scaffold for the recruitment of various complexes including Polycomb repressive complex 2 (PRC2), and required for mouse embryonic stem cell development. However, PRC2 independent function is suggested for Drosophila Jumonji (dJmj). To clarify the function of dJmj during cell differentiation, we used Drosophila adult intestinal stem cell system that allows to follow stem cell behaviors in vivo...

REVIEW
Alexandra Azevedo, Tiago Torres
Psoriasis is a common, chronic, immune-mediated disease associated with several comorbidities. Biologic therapy revolutionized the treatment of moderate-to-severe psoriasis, improving physical and emotional burden of the disease. Still, there are unmet needs in the treatment of psoriasis regarding long-term efficacy, tolerability, safety, route of administration, and cost. The increased knowledge of the pathogenesis of the intracellular metabolic pathways allowed the development of new compounds that inhibit certain intracellular proteins involved in the immune response...

We previously identified a novel inhibitor of La protein, H11, which inhibited hepatitis B virus (HBV) replication by inhibiting the interaction between La protein and HBV RNA. However, the other cellular factors involved in this process remain unclear. To investigate the mechanism of H11-mediated inhibition of HBV infection, a lncRNA microarray analysis was performed using H11-treated and untreated stable HBV-expressing human hepatoblastoma HepG2.2.15 cells. The profiles of differentially expressed lncRNAs and mRNAs were generated and analyzed using Gene Ontology (GO) and pathway analyses...

Resistance to platinum-based chemotherapy is the major barrier to treating high-grade serous ovarian cancer (HGS-OvCa). To improve HGS-OvCa patient prognosis, it is critical to identify the underlying mechanisms that promote platinum resistance. The goal of the present study was to identify a lncRNA-mRNA co-expression network and key lncRNAs that predict resistance to platinum-based chemotherapy in ovarian cancer patients. By systematically analyzing the expression profiles of lncRNAs and mRNAs in HGS-OvCa samples from the Cancer Genome Atlas (TCGA), we revealed that lncRNAs play important roles in platinum resistance in HGS-OvCa patients and delineate a lncRNA-mRNA co-expression network in HGS-OvCa patients who exhibit platinum resistance...

Tofacitinib is an oral JAK inhibitor for the treatment of rheumatoid arthritis. In the 2-year carcinogenicity study with tofacitinib, increased incidence of hibernoma (a neoplasm of brown adipose tissue [BAT]) was noted in female rats at ≥30 mg/kg/day (≥41x human exposure multiples). Thus, signaling pathways within BAT were investigated by measuring BAT: weight, cell proliferation biomarkers, content of basal and prolactin-induced phosphorylated Signal Transducer and Activator of Transcription (STAT), and uncoupling protein 1 (UCP-1)...

The Single von Willebrand factor C-domain proteins (SVCs) are a group of short proteins mainly found in arthropods. They are proposed to be responsive in relation to environmental challenges including the nutritional status, bacterial and viral infections. The SVC protein Vago acts as a cross-talk molecule between the small interfering RNA (siRNA) pathway and the Jak/STAT pathway upon viral infection in Drosophila melanogaster and Culex mosquito cells. Unlike flies and mosquitoes that possess diverse SVCs, most bee species only have one of which the function remains unclear...
