Department of Basic Medical Sciences, College of Veterinary Medicine, Purdue University, West Lafayette, IN, USA.

The factor VII (FVII) protein is an integral component of the extrinsic coagulation pathway. Deleterious variants in the gene encoding this protein can result in factor VII deficiency (FVIID), a bleeding disorder characterized by abnormal (slowed) clotting with a wide range of severity, from asymptomatic to life-threatening. In canids, a single FVIID-associated variant, first described in Beagles, has been observed in 24 breeds and mixed-breed dogs. Read More

Different predictive values of microvessel density for biochemical recurrence among different PCa populations: A systematic review and meta-analysis.

Cancer Med 2022 Aug 7. Epub 2022 Aug 7.

Department of Urology, Institute of Urology, West China Hospital, Sichuan University, Chengdu, PR China.

Background: Several studies have explored the relationship between intratumoral microvessel density (MVD) and the risk of postoperative biochemical recurrence (BCR) in prostate cancer (PCa), although the results are contradictory. Therefore, we conducted a meta-analysis to investigate the effect of MVD on BCR in PCa.

Improvement of recombinant ADAMTS13 production through a more optimal signal peptide or an N-terminal fusion protein.

J Thromb Haemost 2022 Jul 16. Epub 2022 Jul 16.

Laboratory for Thrombosis Research, IRF Life Sciences, KU Leuven Campus Kulak Kortrijk, Kortrijk, Belgium.

Background: Recombinant human ADAMTS13 (rADAMTS13) is a key protein in fundamental research for investigating its mode of action and the pathophysiology of thrombotic thrombocytopenic purpura (TTP). However, the expression of rADAMTS13 is quite low in mammalian cells, which makes the production of the protein time-consuming and labor-intensive.

Objectives: We aimed at increasing the yield of rADAMTS13 by (1) using a more optimal signal peptide (SP) and (2) constructing an N-terminal fusion protein of ADAMTS13 with human serum albumin domain 1 (AD1-ADAMTS13). Read More

Transplant Cell Ther 2022 Jul 11. Epub 2022 Jul 11.

Hematology and Cellular Therapy Service, Hôpital Saint Antoine, AP-HP, Paris, France; INSERM, UMR 938, Paris, France.

Unmanipulated haploidentical hematopoietic stem cell transplantation (HCT) with post-transplantation cyclophosphamide as graft-versus-host disease (GVHD) prophylaxis (haplo-PTCY) and unrelated double-unit umbilical cord blood transplantation (dUCBT) are feasible options for treating patients with high-risk acute myelogenous leukemia (AML). This study compared outcomes after dUCBT and haplo-HCT using peripheral blood stem cells (PBSCs) in adult patients with AML in complete remission (CR) who underwent transplantation in European Society for Blood and Marrow Transplantation (EBMT)-affiliated centers. In a population of adults with de novo AML in first or second CR, we compared outcomes after dUCBT (n = 165) and after haplo-PTCY PBSC (n = 544) performed between January 2013 and December 2018.

LGBTQIA+ rights, mental health systems, and curative violence in India.

Indian J Med Ethics 2022 Apr-Jun;VII(2):127-133

Assistant Professor, Department of Psychology, CHRIST (Deemed-to-be) University, Bengaluru, INDIA.

This commentary examines the space-attitude-administrative complex of mainstream mental health systems with regard to its responses to decriminalisation of non-heteronormative sexual identities. Even though the Supreme Court, in its 2018 order, instructed governments to disseminate its judgment widely, there has been no such attempt till date. None of the government-run mental health institutions has initiated an LGBTQIA+ rights-based awareness campaign on the judgment, considering that lack of awareness about sexualities in itself remains a critical factor for a non-inclusive environment that forces queer individuals to end their lives.

Tissue factor: a neglected role in cancer biology.

J Thromb Thrombolysis 2022 Jul 28;54(1):97-108. Epub 2022 Jun 28.

The Department of Tumor Surgery, Lanzhou University Second Hospital, Lanzhou, China.

Tissue factor (TF), an initiator of extrinsic coagulation pathway, is positively correlated with venous thromboembolism (VTE) of tumor patients. Beyond thrombosis, TF plays a vital role in tumor progression. TF is highly expressed in cancer tissues and circulating tumor cell (CTC), and activates factor VIIa (FVIIa), which increases tumor cells proliferation, angiogenesis, epithelial-mesenchymal transition (EMT) and cancer stem cells(CSCs) activity.

Coagulation factors promote brown adipose tissue dysfunction and abnormal systemic metabolism in obesity.

iScience 2022 Jul 7;25(7):104547. Epub 2022 Jun 7.

Department of Cardiovascular Biology and Medicine, Juntendo University Graduate School of Medicine, 2-1-1 Hongo, Bunkyo-ku, Tokyo 113-8431, Japan.

Brown adipose tissue (BAT) has a role in maintaining systemic metabolic health in rodents and humans. Here, we show that metabolic stress induces BAT to produce coagulation factors, which then-together with molecules derived from the circulation-promote BAT dysfunction and systemic glucose intolerance. When mice were fed a high-fat diet (HFD), the levels of tissue factor, coagulation Factor VII (FVII), activated coagulation Factor X (FXa), and protease-activated receptor 1 (PAR1) expression increased significantly in BAT.

Procoagulant Activity in Amniotic Fluid Is Associated with Fetal-Derived Extracellular Vesicles.

Curr Issues Mol Biol 2022 Jun 13;44(6):2710-2716. Epub 2022 Jun 13.

Hemostasis Research Department, Dmitry Rogachev Pediatric Hematology and Immunology Hospital, Moscow 117997, Russia.

Procoagulant activity in amniotic fluid (AF) is positively correlated with phosphatidylserine (PS) and tissue factor (TF)-expressing(+) extracellular vesicles (EVs). However, it is unknown if pathological fetal conditions may affect the composition, phenotype, and procoagulant potency of EVs in AF. We sought to evaluate EV-dependent procoagulant activity in AF from pregnant people with fetuses with or without diagnosed chromosomal mutations. Read More
