Subcellular partitioning of MRP RNA assessed by ultrastructural and biochemical analysis. [PDF]

, 1994
A small RNA encoded within the nucleus is an essential subunit of a RNA processing endonuclease (RNase MRP) hypothesized to generate primers for mitochondrial DNA replication from the heavy strand origin of replication.

Novel drugs approved by the EMA, the FDA and the MHRA in 2025: A year in review

British Journal of Pharmacology, Volume 183, Issue 9, Page 1779-1813, May 2026.
Abstract In the 2025 novel drug mini‐review, one can take a full measure of the ingenuity that underlies current drug design and development, despite the year's smaller harvest (46 novel drugs) compared to 2024 (53) and 2023 (70). 54% of the novel drugs are first‐in‐class (FIC).

Collagen and microvascular alterations contribute to neuromuscular degeneration and disease progression in chronic intestinal pseudo‐obstruction

Journal of Internal Medicine, Volume 299, Issue 5, Page 587-603, May 2026.
Abstract Background Chronic intestinal pseudo‐obstruction (CIPO) is a severe gastrointestinal motility disorder that may be idiopathic or associated with systemic disease. In idiopathic cases, the pathophysiological mechanisms remain poorly defined. Although mutations in angiogenic factors have been reported in mitochondrial forms of CIPO, their role ...

The Conjugated Bile Acids Profile Suggests a Novel Liver‐Muscle Axis Associated With Sarcopenia in Chronic Liver Disease

Liver International, Volume 46, Issue 5, May 2026.
ABSTRACT Background Liver‐related sarcopenia is a devastating systemic complication of chronic liver disease (CLD) driven by mechanisms extending beyond nutritional deficiency. However, the role of liver‐derived humoral factors remains unclear. We utilised a unique cohort of human skeletal muscle biopsies to test the hypothesis that serum conjugated ...

IFNγ causes mitochondrial dysfunction and oxidative stress in myositis

Nature Communications
Idiopathic inflammatory myopathies (IIMs) are severe autoimmune diseases with poorly understood pathogenesis and unmet medical needs. Here, we examine the role of interferon γ (IFNγ) using NOD female mice deficient in the inducible T cell co-stimulator ...

Caspase‐6 Controls Lipid and Energy Metabolism in Diet‐Induced Obesity

Advanced Science, Volume 13, Issue 21, 13 April 2026.
This study reveals an unknown metabolic role of caspase‐6 beyond cell death. Caspase‐6 deficiency protects against HFD‐induced obesity by increasing energy expenditure, reducing inflammation, and improving glucose metabolism. Mechanistically, caspase‐6 cleaves PPARγ and SP1 to suppress ATGL expression.

Compensatory Interplay Between Clarin‐1 and Clarin‐2 Deafness‐Associated Proteins Governs Phenotypic Variability in Hearing

Advanced Science, Volume 13, Issue 20, 9 April 2026.
Functional compensation between clarin‐1 and clarin‐2 in cochlear hair cells. Hearing loss associated with CLRN1 mutations shows striking phenotypic variability; however, the underlying mechanisms remain poorly understood. This study reveals that clarin‐1 and clarin‐2 function cooperatively in cochlear hair cells to sustain mechanoelectrical ...

Decades of Misdiagnosis as Myasthenia Gravis: Late‐Onset POLG‐Related Ophthalmoplegia Unveiled by Whole‐Genome Sequencing

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT A 55‐year‐old male developed POLG‐related ophthalmoplegia in 2015 and was misdiagnosed with seronegative myasthenia gravis for 10 years. Whole‐genome sequencing identified compound heterozygous POLG mutations, highlighting its value in diagnosing refractory neuromuscular disorders.

Maternal Undernutrition Alters Fetal Muscle Growth, Metabolism, and Transcriptomic Regulation in Intrauterine Growth Restricted Sheep

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
Maternal undernutrition in late pregnancy restricts fetal skeletal muscle growth and shifts muscle fiber types to fast muscle types. These changes are driven by changes in mitochondrial enzymes and DNA, endoplasmic reticulum stress, and ribosomal activity that predispose postnatal offspring to metabolic disorders.
