Background: Given burdensome side-effects and long latency for efficacy with conventional agents, there is a continued need for generalised myasthenia gravis treatments that are safe and provide consistently sustained, long-term disease control. Nipocalimab, a neonatal Fc receptor blocker, was associated with dose-dependent reductions in total IgG and anti-acetylcholine receptor (AChR) antibodies and clinically meaningful improvements in the Myasthenia Gravis Activities of Daily Living (MG-ADL) scale in patients with generalised myasthenia gravis in a phase 2 study. We aimed to assess the safety and efficacy of nipocalimab in a phase 3 study.

Distinguishing tumor maintenance genes from initiation, progression, and passenger genes is critical for developing effective therapies. We employed a functional genomic approach using the Lazy Piggy transposon to identify tumor maintenance genes in vivo and applied this to sonic hedgehog (SHH) medulloblastoma (MB). Combining Lazy Piggy screening in mice and transcriptomic profiling of human MB, we identified the voltage-gated potassium channel KCNB2 as a candidate maintenance driver.

Clinical studies of blood-borne Extracellular vesicles in psychiatry: A systematic review.

J Psychiatr Res

January 2025

Department of Molecular Cell Biology, Institute for Cancer Research, Oslo University Hospital, 0379, Oslo, Norway; Centre for Cancer Cell Reprogramming, Faculty of Medicine, University of Oslo, Oslo, Norway; Department for Mechanical, Electronics and Chemical Engineering, Oslo Metropolitan University, Oslo, Norway.

Biomarkers for the diagnosis and clinical management of psychiatric disorders are currently lacking. Extracellular vesicles (EVs), lipid membrane-encapsulated vesicles released by cells, hold promise as a source of biomarkers due to their ability to carry molecules that reflect the status of their donor cells and their ubiquitous presence in biofluids. This review examines the literature on EVs in biofluids from psychiatric disorder patients, and discuss how the published studies contribute to our understanding of the pathophysiology of these conditions and to the discovery of potential biomarkers.

Single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) techniques hold great value in evaluating the heterogeneity and spatial characteristics of hematopoietic cells within tissues. These two techniques are highly complementary, with scRNA-seq offering single-cell resolution and ST retaining spatial information. However, there is an urgent demand for well-organized and user-friendly toolkits capable of handling single-cell and spatial information.

Purpose: Intramuscular acton prolongatum is most often used as an alternative for intramuscular or intravenous tetracosactide for ACTH stimulation in some countries. Intramuscular administration of acton prolongatum is cumbersome whereas intended intramuscular acton prolongatum or tetracosactide may often turn subcutaneous. Hence, we compared the subcutaneous ACTH-stimulated steroid profiling with those of the intramuscular routes.

The p60 subunit of the chromatin assembly factor-1 complex, that is, chromatin assembly factor-1 subunit B (CHAF1B), is a histone H3/H4 chaperone crucial for the transcriptional regulation of cell differentiation and self-renewal. CHAF1B is overexpressed in several cancers and may represent a potential target for cancer therapy. However, its expression and clinical significance in lung squamous-cell carcinoma (LUSC) remain unclear.

Pituitary adenomas: biology, nomenclature and clinical classification.

Rev Endocr Metab Disord

January 2025

Pituitary Center, Cedars-Sinai Medical Center, Los Angeles, CA, USA.

An 'adenoma' is a benign neoplasm composed of epithelial tissue, and has been standard nomenclature for primary pituitary neoplasms. In 2022, the fifth edition of the WHO Classification of Endocrine Tumours and of Central Nervous System Tumours, renamed pituitary adenomas as neuroendocrine tumours (NETs), assigning an oncology label to pituitary invariably benign neoplasms. Multidisciplinary workshops convened by the Pituitary Society have questioned the process, validity, and merit of this arbitrary change, while addressing the adverse clinical implications of the proposed new nomenclature.

Purpose: Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age, often leading to anovulatory infertility. Obesity exacerbates the reproductive, metabolic and psychological features of PCOS, making fertility treatment and patient satisfaction difficult. Despite guidelines from the European Society of Human Reproduction and Embryology (ESHRE) emphasizing lifestyle modifications and specific treatments, there remains a significant gap in adherence to these guidelines by both healthcare providers and patients.
