Stat proteins and oncogenesis [PDF]

Journal of Clinical Investigation, 2002
The discovery of Stat proteins’ key role in IFN signaling, initially described over ten years ago, provided the first molecular link of growth factor receptor stimulation to the direct activation of a transcription factor (1). Since that time a large number of growth factor receptors and some nonreceptor tyrosine kinases have been found to lead to the ...

Targeting WTAP/ROR1/WNT5A‐Mediated Crosstalk Between Glioma Stem Cells and Macrophages to Normalize Tumor Vasculature and Enhance Chemotherapy

Advanced Science, EarlyView.
In hypoxic microenvironment, WNT5A is predominantly secreted by tumor‐associated macrophages. Hypoxia‐induced WTAP mediates ROR1 stability by m6A modifications in a HuR‐dependent manner in Glioma stem cells (GSCs). WNT5A activates the WNT pathway via ROR1 binding on GSCs, driving glioma‐derived endothelial cells (GDECs) differentiation.

Dual Aptamers‐Based SETDB1 PROTACs as Effective Anti‐Tumor Strategies for Breast Cancer

Advanced Science, EarlyView.
This study establishes dual‐aptamer PROTACs targeting SETDB1 using a SETDB1‐specific aptamer conjugated to AS1411. The designed PROTACs penetrate cells, recruit MDM2 to degrade SETDB1, and inhibit cancer cell proliferation and migration. Remarkably, they also overcome tamoxifen resistance and enhance CD8+ T cell cytotoxicity, suppressing tumor growth ...

PROTAC‑Mediated HMGCR Depletion Reprograms Lipid Metabolism in Breast Cancer to Potentiate Photoimmunotherapy via Ferroptosis

Advanced Science, EarlyView.
This work introduces a study that identifies HMGCR as a novel target in TNBC and develops a light‐gated PROTAC nanomedicine. Upon irradiation, this agent selectively degrades HMGCR, reprogramming lipid metabolism to induce ferroptosis and potent antitumor immunity, thereby significantly enhancing photoimmunotherapy efficacy.

Targeting the Spliceosomal Protein USP39 Through Allosteric Ligands and PROTAC‐Induced Degradation

Angewandte Chemie International Edition, EarlyView.
Proteolysis‐targeting chimeras (PROTACs) enable degradation of proteins previously considered undruggable by harnessing the cellular ubiquitin–proteasome system. In this study, Schäfer et al. identify thiazole‐based small molecules that allosterically bind the zinc finger domain of ubiquitin‐specific protease 39 (USP39), a non‐enzymatic scaffold ...

Association of the Human Bocavirus With Tonsil Squamous Cell Carcinomas

Frontiers in Microbiology, 2018
Background: The human bocavirus (HBoV) is known to persist latently in the infected host cells and seems to replicate its DNA via the DNA damage response system, which is frequently defect in tumors and correlates with microsatellite instability (MSI ...

Versatile and Selective Biomolecule Pulldown with Combinatorial DNA‐Crosslinked Polymers

Angewandte Chemie International Edition, EarlyView.
We present a programmable smart polymer system for universal, sequence‐selective bioseparation under native conditions. Polymer phase separation is achieved through combinatorial DNA crosslinking, enabling the capture of DNA, RNA, or proteins in a homogeneous solution with high pulldown efficiency and near‐zero background binding.

Bioactive Phytochemical Compounds in Medicago sativa L. (Alfalfa): A Systematic Review of Biological Properties and Therapeutic Relevance in Nutraceutical and Functional Food Implications

Food Frontiers, EarlyView.
ABSTRACT Medicago sativa L. (alfalfa) harbors a remarkably diverse reservoir of bioactive secondary metabolites. Flavonoids, isoflavones, and triterpenoid saponins dominate its bioactivity landscape, driving potent antioxidant, anti‐inflammatory, antimicrobial, estrogenic, hypolipidemic, and cytotoxic actions through redox modulation, membrane ...
