The impact of identity by descent on fitness and disease in dogs.

Proc Natl Acad Sci U S A 2021 Apr;118(16)

Department of Human Genetics, University of California, Los Angeles, CA 90095;

Domestic dogs have experienced population bottlenecks, recent inbreeding, and strong artificial selection. These processes have simplified the genetic architecture of complex traits, allowed deleterious variation to persist, and increased both identity-by-descent (IBD) segments and runs of homozygosity (ROH). As such, dogs provide an excellent model for examining how these evolutionary processes influence disease. Read More

B Cell Receptor-Responsive miR-141 Enhances Epstein-Barr Virus Lytic Cycle via FOXO3 Inhibition.

mSphere 2021 Apr 14;6(2). Epub 2021 Apr 14.

Vaccine and Gene Therapy Institute, Oregon Health & Science University, Beaverton, Oregon, USA

Antigen recognition by the B cell receptor (BCR) is a physiological trigger for reactivation of Epstein-Barr virus (EBV) and can be recapitulated by cross-linking of surface immunoglobulins. Previously, we identified a subset of EBV microRNAs (miRNAs) that attenuate BCR signal transduction and subsequently dampen lytic reactivation in B cells. The roles of host miRNAs in the EBV lytic cycle are not completely understood. Read More

Bioorg Med Chem 2021 Apr 2;38:116130. Epub 2021 Apr 2.

State Key Laboratory of Natural Medicines, and Jiang Su Key Laboratory of Drug Design and Optimization, China Pharmaceutical University, Nanjing 210009, China; Department of Medicinal Chemistry, School of Pharmacy, China Pharmaceutical University, Nanjing 210009, China. Electronic address:

Protein-protein interactions (PPIs) are essentially fundamental to all cellular processes, so that developing small molecule inhibitors of PPIs have great significance despite representing a huge challenge. Studying PPIs with the help of peptide motifs could obtain the structural information and reference significance to reduce the difficulty in the development of small molecules. Computational methods are powerful tools to characterize peptide-protein interactions, especially molecular dynamics simulation and binding free energy calculation. Read More

Perspectives on outpatient administration of CAR-T cell therapy in aggressive B-cell lymphoma and acute lymphoblastic leukemia.

J Immunother Cancer 2021 Apr;9(4)

BMT & Cell Therapy Program, Division of Hematology/Medical Oncology, Knight Cancer Institute, Oregon Health and Science University, Portland, Oregon, USA.

Chimeric antigen receptor (CAR) T-cell therapies that specifically target the CD19 antigen have emerged as a highly effective treatment option in patients with refractory B-cell hematological malignancies. Safety and efficacy outcomes from the pivotal prospective clinical trials of axicabtagene ciloleucel, tisagenlecleucel and lisocabtagene maraleucel and the retrospective, postmarketing, real-world analyses have confirmed high response rates and durable remissions in patients who had failed multiple lines of therapy and had no meaningful treatment options. Although initially administered in the inpatient setting, there has been a growing interest in delivering CAR-T cell therapy in the outpatient setting; however, this has not been adopted as standard clinical practice for multiple reasons, including logistic and reimbursement issues.

Refining the management of relapsed or refractory follicular lymphoma.

Clin Adv Hematol Oncol 2020 Dec;18 Suppl 20(12):1-24

John Theurer Cancer Center, Hackensack, New Jersey.

In patients with follicular lymphoma, the prolonged clinical course consisting of multiple relapses is a fundamental challenge that requires clinicians to consider how to best balance treatment efficacy while minimizing toxicity and preserving quality of life. The treatment approaches and decisions regarding therapy are largely driven by the unique clinical features evident in each patient. The traditional treatment approaches for relapsed follicular lymphoma include chemoimmunotherapy regimens, targeted agents, radioimmunotherapy, and, occasionally, immunotherapy alone. Read More

Utility of vertebral biopsy before vertebroplasty in patients with diagnosis of vertebral compression fracture.

Radiol Med 2021 Apr 12. Epub 2021 Apr 12.

SC Neuroradiologia, ASST Carlo Poma, Str. Lago Paiolo, 10, 46100, Mantova, MN, Italy.

Purpose: To demonstrate the utility of a biopsy performed just before vertebroplasty in patients with diagnosis of vertebral compression fracture (VCF) and no history of neoplastic or hematologic diseases.

Background: Osteoporosis is the most frequent cause of vertebral compression fracture, with trauma and pathologic vertebral weakening being other common causes. Since secondary fractures at imaging investigation can present as simple compression fractures, it is important to identify an underlying pathology. Read More

Transplant Cell Ther 2021 Apr 17;27(4):310.e1-310.e6. Epub 2020 Dec 17.

Department of Medicine, University of Minnesota, Minneapolis, Minnesota.

Adaptive natural killer (NK) cells are long-lived and exhibit properties of immunologic memory against cytomegalovirus (CMV). We previously reported that expansion of adaptive NK cells after CMV reactivation in recipients of allogeneic hematopoietic cell transplantation (HCT) was associated with a lower rate of relapse of acute myelogenous leukemia. In the present study, we examined the impact of adaptive NK cell expansion in a cohort of 110 individuals who underwent autologous HCT (AHCT) for a lymphoid malignancy (lymphoma or multiple myeloma [MM]).

A Case of Sarcoidosis Mimicking Lymphoma Confounded by Cognitive Decline.

Cureus 2021 Mar 3;13(3):e13667. Epub 2021 Mar 3.

Internal Medicine, Wake Forest Baptist Medical Center, Winston-Salem, USA.

Sarcoidosis is a disease with an unknown cause that affects multiple organ systems and has a varied clinical presentation. Often, its symptomatology mimics other disease processes, such as lymphoma, tuberculosis, and amyloidosis. The reticuloendothelial involvement and typical B symptoms of weight loss, fatigue, night sweats, and lymphadenopathy can make sarcoidosis often easily confused with lymphoma. Read More

A rare variant in EZH2 is associated with prostate cancer risk.

Int J Cancer 2021 Apr 6. Epub 2021 Apr 6.

Menzies Institute for Medical Research, University of Tasmania, Hobart, Tasmania, Australia.

Prostate cancer (PrCa) is highly heritable, and although rare variants contribute significantly to PrCa risk, few have been identified to date. Herein, whole-genome sequencing was performed in a large PrCa family featuring multiple affected relatives spanning several generations. A rare, predicted splice site EZH2 variant, rs78589034 (G > A), was identified as segregating with disease in all but two individuals in the family, one of whom was affected with lymphoma and bowel cancer and a female relative.

TNB-486 induces potent tumor cell cytotoxicity coupled with low cytokine release in preclinical models of B-NHL.

MAbs 2021 Jan-Dec;13(1):1890411

Teneobio, Inc., Newark, CA, United States.

The therapeutic potential of targeting CD19 in B cell malignancies has garnered attention in the past decade, resulting in the introduction of novel immunotherapy agents. Encouraging clinical data have been reported for T cell-based targeting agents, such as anti-CD19/CD3 bispecific T-cell engager blinatumomab and chimeric antigen receptor (CAR)-T therapies, for acute lymphoblastic leukemia and B cell non-Hodgkin lymphoma (B-NHL). However, clinical use of both blinatumomab and CAR-T therapies has been limited due to unfavorable pharmacokinetics (PK), significant toxicity associated with cytokine release syndrome and neurotoxicity, and manufacturing challenges.

Front Oncol 2021 18;11:658234. Epub 2021 Mar 18.

Department of Hematology, Beijing Tiantan Hospital, Capital Medical University, Beijing, China.

Non-Hodgkin lymphoma (NHL) is a common type of hematological malignant tumor, composed of multiple subtypes that originate from B lymphocytes, T lymphocytes, and natural killer cells. A diagnosis of NHL depends on the results of a pathology examination, which requires an invasive tissue biopsy. However, due to their invasive nature, tissue biopsies have many limitations in clinical applications, especially in terms of evaluating the therapeutic response and monitoring tumor progression.
