De novo cyclic peptides allow visualisation of the monomeric and functional amyloid conformations of the kinase RIPK3.
Receptor interacting protein kinase 3 (RIPK3) is a central regulator of necroptosis and a key mediator of inflammatory signalling. Its function is orchestrated through RIP homotypic interaction motif (RHIM)-dependent interactions with other RHIM-containing adapter proteins, forming amyloid-structured necrosomes that tr...

On-Resin Pictet-Spengler Cyclization for 1,2,3,4-Tetrahydro-β-carboline-3-carboxylate (Tcc) Peptide Synthesis With Acid-Labile Functional Tolerance.
The constrained tryptophan (Trp) analog 1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid (Tcc) is used to restrict peptide conformation in structure-activity relationship studies. Although Pictet-Spengler cyclization of Trp and aldehydes with mineral acid gives Tcc analogs, such harsh conditions do not tolerate acid-la...

Spine age derived from DXA vertebral fracture assessment images predicts incident fractures and mortality: the Manitoba Bone Mineral Density Registry.
Biological age may better predict health outcomes than chronological age by capturing individual heterogeneity in aging. We investigated whether accelerated spine aging, estimated from DXA vertebral fracture assessment (VFA) using deep learning, predicts fracture and mortality independently of age, vertebral fracture (...

Multi-layered gene regulation by long non-coding RNAs: from chromatin to genome architecture.
Long non-coding RNAs (lncRNAs) are now recognized as pivotal regulators that enable the fine-tuned control of gene expression. While the functional diversity of lncRNAs challenges comprehensive understanding of their mechanisms, recent advances have revealed how these molecules coordinate epigenomic control, ranging fr...

FLT3-directed BiTE molecules vs CAR T cells in AML: costimulatory signals mitigate T-cell exhaustion.
<h4>Abstract</h4>T-cell-based immunotherapies have revolutionized treatment paradigms in B-cell malignancies, yet their translation to acute myeloid leukemia (AML) has been hindered by a scarcity of tumor-restricted antigens and the risk of on-target off-leukemia toxicity. FLT3 has emerged as a promising therapeutic ta...
