roli Indirect Evidence of Bourbon Virus (Thogotovirus, Orthomyxoviridae) Infection in North Carolina By www.ncmedicaljournal.com Published On :: 2020-05-04T06:50:30-07:00 To the Editor—Bourbon virus (Thogotovirus, Orthomyxoviridae) was discovered in 2014 when a patient with history of multiple tick bites in Kansas died from an unknown infection [1]. Human infections from Bourbon virus have now been recognized in several states (i.e., Kansas, Oklahoma, Missouri). The virus was detected in collections of the lone star tick (Amblyomma americanum) in Missouri [2]. A serosurvey of domestic and wild mammals in Missouri noted the presence of Bourbon virus-neutralizing antibodies in serum samples collected from a variety of species, but most frequently in white-tailed deer (Odocoileus virginianus) and raccoon (Procyon lotor) [3]. We report here that neutralizing antibodies against Bourbon virus were detected in white-tailed deer in North Carolina, suggesting that the virus is present in the state. We screened 32 white-tailed deer for the presence of Bourbon virus-specific neutralizing antibodies. Of 20 plasma samples that reacted with the virus, 18 were confirmed with neutralizing antibody titers ranging from 10 to ≥ 320 for a seroprevalence rate of 56% (95% confidence interval 39%–72%). The seropositive samples were from deer killed during the 2014 hunting season from Stanly and New Hanover counties. The incidence of Bourbon virus infection in humans in North Carolina is unknown. However, given the abundance of the lone star tick in the state, and the notable proportion of deer with evidence of infection, human infections have likely gone unnoticed or possibly misdiagnosed. Human infection with Bourbon virus results in a nonspecific viral syndrome that includes fever, nausea, diarrhea, myalgia (muscle pain), arthralgia... Full Article

roli Vital Directions for Health & Health Care: The North Carolina Experience By www.ncmedicaljournal.com Published On :: 2020-05-04T06:50:30-07:00 In 2019, the National Academy of Medicine (NAM) turned to the all-important state level to draw insights on the status of health and health care within the context of the NAM Vital Directions for Health and Health Care initiative. The NAM held a two-day symposium in the Research Triangle to bring together various stakeholders to better understand actions that states and localities are taking to achieve—and the barriers they face in pursuing—more affordable, value-driven quality care and health outcomes. The NAM purposefully chose to pivot to the state level with North Carolina given that it has been at the forefront of health care transformation and illustrates the promise but also the challenges facing US health and health care nationally. A 19-member planning committee, cochaired by NAM President Victor Dzau and Secretary Mandy Cohen of the North Carolina Department of Health and Human Services, selected topics that resonate with the state's activities within the context of the Vital Directions framework, ranging from empowering people and connecting care through the integration of social, physical, and behavioral health to payer alignment though the advancement of new payment models (Figure 1). The priorities discussed during the symposium continue to be central to health reform in North Carolina and are further explored in the commentaries in this issue. Full Article
roli A Cohort Comparison of Differences Between Regional and Buncombe County Patients of a Comprehensive Perinatal Substance Use Disorders Program in Western North Carolina By www.ncmedicaljournal.com Published On :: 2020-05-04T06:50:30-07:00 BACKGROUND Pregnant patients from rural counties of Western North Carolina face additional barriers when accessing comprehensive perinatal substance use disorders care at Project CARA as compared to patients local to the program in Buncombe County. We hypothesized regional patients would be less engaged in care. METHOD Using a retrospective cohort design, univariate analyses (2, t-test; P < .05) compared patients' characteristics, engagement in care, and delivery outcomes. Engagement in care, the primary outcome, was operationalized as: attendance at expected, program-specific prenatal and postpartum visits, utilization of in-house counseling, community-based and/or inpatient substance use disorders treatment, and maternal urine drug screen at delivery negative for illicit substances. RESULTS Regional patients (n = 324) were more likely than Buncombe County patients (n = 284) to have opioid [209 (64.5%) versus 162 (57.0%)] or amphetamine/methamphetamine use disorders (25 [7.7%] versus 13 [4.6%]), but less likely to have cannabis use (19 [5.9%] versus 38 [13.4%]; P = .009) and concurrent psychiatric disorders (214 [66.0%] versus 220 [77.5%]; P = .002). Engagement at postpartum visits was the significantly different outcome between patients (110/221 [49.8%] versus 146/226 [64.6%]; P = .002). LIMITATIONS Outcomes were available for 66.8% of regional and 79.6% of Buncombe County patients of one program in one predominately white, non-Hispanic region of the state. CONCLUSION Contrary to our hypothesis, regional and Buncombe County women engaged in prenatal care equally. However, a more formal transition into the postpartum period is needed, especially for regional women. A "hub-and-spokes" model that extends delivery of perinatal substance use disorders care into rural communities may be more effective for engagement retention. Full Article
roli SUMOylation of the transcription factor ZFHX3 at Lys-2806 requires SAE1, UBC9, and PIAS2 and enhances its stability and function in cell proliferation [Protein Synthesis and Degradation] By www.jbc.org Published On :: 2020-05-08T03:41:14-07:00 SUMOylation is a posttranslational modification (PTM) at a lysine residue and is crucial for the proper functions of many proteins, particularly of transcription factors, in various biological processes. Zinc finger homeobox 3 (ZFHX3), also known as AT motif-binding factor 1 (ATBF1), is a large transcription factor that is active in multiple pathological processes, including atrial fibrillation and carcinogenesis, and in circadian regulation and development. We have previously demonstrated that ZFHX3 is SUMOylated at three or more lysine residues. Here, we investigated which enzymes regulate ZFHX3 SUMOylation and whether SUMOylation modulates ZFHX3 stability and function. We found that SUMO1, SUMO2, and SUMO3 each are conjugated to ZFHX3. Multiple lysine residues in ZFHX3 were SUMOylated, but Lys-2806 was the major SUMOylation site, and we also found that it is highly conserved among ZFHX3 orthologs from different animal species. Using molecular analyses, we identified the enzymes that mediate ZFHX3 SUMOylation; these included SUMO1-activating enzyme subunit 1 (SAE1), an E1-activating enzyme; SUMO-conjugating enzyme UBC9 (UBC9), an E2-conjugating enzyme; and protein inhibitor of activated STAT2 (PIAS2), an E3 ligase. Multiple analyses established that both SUMO-specific peptidase 1 (SENP1) and SENP2 deSUMOylate ZFHX3. SUMOylation at Lys-2806 enhanced ZFHX3 stability by interfering with its ubiquitination and proteasomal degradation. Functionally, Lys-2806 SUMOylation enabled ZFHX3-mediated cell proliferation and xenograft tumor growth of the MDA-MB-231 breast cancer cell line. These findings reveal the enzymes involved in, and the functional consequences of, ZFHX3 SUMOylation, insights that may help shed light on ZFHX3's roles in various cellular and pathophysiological processes.

roli Cordycepin Inhibits Cancer Cell Proliferation and Angiogenesis through a DEK Interaction via ERK Signaling in Cholangiocarcinoma [Gastrointestinal, Hepatic, Pulmonary, and Renal] By jpet.aspetjournals.org Published On :: 2020-04-21T06:02:31-07:00 Cholangiocarcinoma (CCA) is a malignant tumor that arises from the epithelial cells of the bile duct and is notorious for its poor prognosis. The clinical outcome remains disappointing, and thus more effective therapeutic options are urgently required. Cordycepin, a traditional Chinese medicine, provides multiple pharmacological strategies in antitumors, but its mechanisms have not been fully elucidated. In this study, we reported that cordycepin inhibited the viability and proliferation capacity of CCA cells in a time- and dose-dependent manner determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) and colony formation assay. Flow cytometry and Hoechst dye showed that cordycepin induced cancer cell apoptosis via extracellular signal-regulated kinase (ERK) 1/2 deactivation. Moreover, cordycepin significantly reduced the angiogenetic capabilities of CCA in vitro as examined by tube formation assay. We also discovered that cordycepin inhibited DEK expression by using Western blot assay. DEK serves as an oncogenic protein that is overexpressed in various gastrointestinal tumors. DEK silencing inhibited CCA cell viability and angiogenesis but not apoptosis induction determined by Western blot and flow cytometry. Furthermore, cordycepin significantly inhibited tumor growth and angiogenic capacities in a xenograft model by downregulating the expression of DEK, phosphorylated ERK1/2 CD31 and von Willebrand factor (vWF). Taken together, we demonstrated that cordycepin inhibited CCA cell proliferation and angiogenesis with a DEK interaction via downregulation in ERK signaling. These data indicate that cordycepin may serve as a novel agent for CCA clinical treatment and prognosis improvement. SIGNIFICANCE STATEMENT Cordycepin provides multiple strategies in antitumors, but its mechanisms are not fully elucidated, especially on cholangiocarcinoma (CCA). We reported that cordycepin inhibited the viability of CCA cells, induced apoptosis via extracellular signal-regulated kinase 1/2 deactivation and DEK inhibition, and reduced the angiogenetic capabilities of CCA both in vivo and in vitro.

roli Breast Cancer 18F-ISO-1 Uptake as a Marker of Proliferation Status By jnm.snmjournals.org Published On :: 2020-05-01T06:31:37-07:00 The 2 receptor is a potential in vivo target for measuring proliferative status in cancer. The feasibility of using N-(4-(6,7-dimethoxy-3,4-dihydroisoquinolin-2(1H)-yl)butyl)-2-(2-18F-fluoroethoxy)-5-methylbenzamide (18F-ISO-1) to image solid tumors in lymphoma, breast cancer, and head and neck cancer has been previously established. Here, we report the results of the first dedicated clinical trial of 18F-ISO-1 in women with primary breast cancer. Our study objective was to determine whether 18F-ISO-1 PET could provide an in vivo measure of tumor proliferative status, and we hypothesized that uptake would correlate with a tissue-based assay of proliferation, namely Ki-67 expression. Methods: Twenty-eight women with 29 primary invasive breast cancers were prospectively enrolled in a clinical trial (NCT 02284919) between March 2015 and January 2017. Each received an injection of 278–527 MBq of 18F-ISO-1 and then underwent PET/CT imaging of the breasts 50–55 min later. In vivo uptake of 18F-ISO-1 was quantitated by SUVmax and distribution volume ratios and was compared with ex vivo immunohistochemistry for Ki-67. Wilcoxon rank-sum tests assessed uptake differences across Ki-67 thresholds, and Spearman correlation tested associations between uptake and Ki-67. Results: Tumor SUVmax (median, 2.0 g/mL; range, 1.3–3.3 g/mL), partial-volume–corrected SUVmax, and SUV ratios were tested against Ki-67. Tumors stratified into the high–Ki-67 (≥20%) group had SUVmax greater than the low–Ki-67 (<20%) group (P = 0.02). SUVmax exhibited a positive correlation with Ki-67 across all breast cancer subtypes ( = 0.46, P = 0.01, n = 29). Partial-volume–corrected SUVmax was positively correlated with Ki-67 for invasive ductal carcinoma ( = 0.51, P = 0.02, n = 21). Tumor–to–normal-tissue ratios and tumor distribution volume ratio did not correlate with Ki-67 (P > 0.05). Conclusion: 18F-ISO-1 uptake in breast cancer modestly correlates with an in vitro assay of proliferation. Full Article
roli An intronic deletion in megakaryoblastic leukemia 1 is associated with hyperproliferation of B cells in triplets with Hodgkin lymphoma By www.haematologica.org Published On :: 2020-05-01T00:05:42-07:00 Megakaryoblastic leukemia 1 (MKL1) is a coactivator of serum response factor and together they regulate transcription of actin cytoskeleton genes. MKL1 is associated with hematologic malignancies and immunodeficiency, but its role in B cells is unexplored. Here we examined B cells from monozygotic triplets with an intronic deletion in MKL1, two of whom had been previously treated for Hodgkin lymphoma (HL). To investigate MKL1 and B-cell responses in the pathogenesis of HL, we generated Epstein-Barr virus-transformed lymphoblastoid cell lines from the triplets and two controls. While cells from the patients with treated HL had a phenotype close to that of the healthy controls, cells from the undiagnosed triplet had increased MKL1 mRNA, increased MKL1 protein, and elevated expression of MKL1-dependent genes. This profile was associated with elevated actin content, increased cell spreading, decreased expression of CD11a integrin molecules, and delayed aggregation. Moreover, cells from the undiagnosed triplet proliferated faster, displayed a higher proportion of cells with hyperploidy, and formed large tumors in vivo. This phenotype was reversible by inhibiting MKL1 activity. Interestingly, cells from the triplet treated for HL in 1985 contained two subpopulations: one with high expression of CD11a that behaved like control cells and the other with low expression of CD11a that formed large tumors in vivo similar to cells from the undiagnosed triplet. This implies that pre-malignant cells had re-emerged a long time after treatment. Together, these data suggest that dysregulated MKL1 activity participates in B-cell transformation and the pathogenesis of HL. Full Article
roli Early growth response 1 regulates hematopoietic support and proliferation in human primary bone marrow stromal cells By www.haematologica.org Published On :: 2020-05-01T00:05:41-07:00 Human bone marrow stromal cells (BMSC) are key elements of the hematopoietic environment and they play a central role in bone and bone marrow physiology. However, how key stromal cell functions are regulated is largely unknown. We analyzed the role of the immediate early response transcription factor EGR1 as key stromal cell regulator and found that EGR1 was highly expressed in prospectively-isolated primary BMSC, down-regulated upon culture, and low in non-colony-forming CD45neg stromal cells. Furthermore, EGR1 expression was lower in proliferative regenerating adult and fetal primary cells compared to adult steady-state BMSC. Overexpression of EGR1 in stromal cells induced potent hematopoietic stroma support as indicated by an increased production of transplantable CD34+CD90+ hematopoietic stem cells in expansion co-cultures. The improvement in bone marrow stroma support function was mediated by increased expression of hematopoietic supporting genes, such as VCAM1 and CCL28. Furthermore, EGR1 overexpression markedly decreased stromal cell proliferation whereas EGR1 knockdown caused the opposite effects. These findings thus show that EGR1 is a key stromal transcription factor with a dual role in regulating proliferation and hematopoietic stroma support function that is controlling a genetic program to co-ordinate the specific functions of BMSC in their different biological contexts.
