Structural basis of ligand selectivity in FAD/NAD(P)H‐dependent dehydrogenases: insights from trypanothione reductase and type II NADH dehydrogenase

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract FAD/NAD(P)H‐dependent dehydrogenases form a structurally conserved family of redox enzymes that participate in essential metabolic processes across parasites and higher organisms. Among them, trypanothione reductase (TR) is a key component of the redox metabolism of Leishmania species and represents an attractive target for antileishmanial ...

Nuclear kpc-sized Disks of Spiral Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1999
The complex structure of nuclear disks of normal spiral galaxies is illustrated with the example of five galaxies, observed at the 6m telescope. The problem of gravitational stability of nuclear disks is briefly discussed.

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

open access: yesMolecular Oncology, Volume 20, Issue 6, Page 1473-1493, June 2026.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...

β‐Adrenergic Signaling Promotes Anti‐Tumor Immunity in TP53‐mutant Oral Squamous Cell Carcinoma

open access: yesAdvanced Science, Volume 13, Issue 35, 24 June 2026.
β‐adrenergic stimulation enhances anti‐tumor immunity in TP53‐deficient oral squamous cell carcinoma by inducing tumor‐derived secretion of CXCL10, which attracts and activates cytotoxic CD8+ T cells. The findings demonstrate that β‐adrenergic signaling alters tumor–immune interactions via CXCL10‐mediated paracrine activation, revealing a neuro‐immune ...

Tumorigenicity of KC and KPC cell lines.

open access: yes, 2013
(A) The tumorigenic properties of UN-KC-6141, UN-KPC-960, and UN-KPC-961 cells were evaluated after orthotopic (OT) (N = 7) implantation of 1×106 cells in the respective mice background. Subcutaneous (SC) injections of UN-KPC-961 cells (5×106 cells) were

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

open access: yesAdvanced Science, Volume 13, Issue 35, 24 June 2026.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome
