Mitochondria‐associated membranes (MAMs): molecular organization, cellular functions, and their role in health and disease

FEBS Open Bio, EarlyView.
Mitochondria‐associated membranes (MAMs) are contact sites between the endoplasmic reticulum and mitochondria that regulate calcium signaling, lipid metabolism, autophagy, and stress responses. This review outlines their molecular organization, roles in cellular homeostasis, and how dysfunction drives neurodegeneration, metabolic disease, cancer, and ...

C-19 and Hot, Wide Star Streams

The Astrophysical Journal
The C-19 star stream has the abundance characteristics of an unusually metal-poor globular cluster but kinematically is uncharacteristically hot and wide for a cluster stream, having a line-of-sight velocity dispersion of 7  ±  2 km s ^−1 and a 1 σ width

The origins of neutron-capture elements in globular cluster M22

Frontiers in Astronomy and Space Sciences
IntroductionThe chemical abundances of metal poor (MP) stars in globular clusters provide valuable information for constraining their evolutionary scenarios.MethodsUsing both main r-process and weak r-process patterns, we fit the abundances of s-poor ...

Interplay between RNA‐protein interactions and RNA structures in gene regulation

FEBS Open Bio, EarlyView.
Methodological advances in mapping transcriptome‐wide RNA‐protein interactions and RNA structures have started to uncover the potential of RNP conformations in gene regulation. Competing RNA–RNA, RNA‐protein and protein–protein interactions shape the compaction and function of RNPs throughout their lifetime and may provide novel therapeutic targets in ...

Thrombolytic proteins profiling: High‐throughput activity, selectivity, and resistance assays

FEBS Open Bio, EarlyView.
We present optimized biochemical protocols for evaluating thrombolytic proteins, enabling rapid and robust screening of enzymatic activity, inhibition resistance, and fibrin affinity, stimulation, and selectivity. The outcome translates to key clinical indicators such as biological half‐life and bleeding risk. These assays streamline the development of

Age‐Related Changes in Myeloid Cells and Their Impact on Subcutaneous Melanoma Growth in Mice

Aging and Cancer, EarlyView.
Our findings reveal that age‐related changes in subcutaneous melanoma growth and immunotherapy response are context‐dependent. In models where tumor growth and treatment resistance increase with age, this effect is partly driven by enhanced immunosuppression from myeloperoxidase‐active Gr‐1⁺ myeloid cells.

Improved Particle Spray Algorithm for Modeling Globular Cluster Streams

The Astrophysical Journal Supplement Series
Stellar streams that emerge from globular clusters (GCs) are thin stellar structures spread along the orbits of progenitor clusters. Numerical modeling of these streams is essential for understanding their interaction with the host galaxy's mass ...

Durable B‐Cell Impairment While Sparing IgA B Cells After Ocrelizumab Therapy in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Ocrelizumab (OCR), a humanized anti‐CD20 monoclonal antibody, is highly efficient in relapsing–remitting multiple sclerosis (RR‐MS). We assessed early cellular B‐cell profiles in patients prior to OCR treatment, on OCR treatment, and after 15 months of therapy discontinuation.
