Imatinib inhibits VEGF-independent angiogenesis by targeting neuropilin 1-dependent ABL1 activation in endothelial cells. [PDF]

open access: yes, 2014
To enable new blood vessel growth, endothelial cells (ECs) express neuropilin 1 (NRP1), and NRP1 associates with the receptor tyrosine kinase VEGFR2 after binding the vascular endothelial growth factor A (VEGF) to enhance arteriogenesis.

Pathogenicity of Mediator Complex Subunit 27 (MED27) in a Neurodevelopmental Disorder with Cerebellar Atrophy

open access: yesAdvanced Science, EarlyView.
MED27 is one of the 26 subunits in the human Mediator complex (MED). Neurodevelopmental disorder‐causing MED27 genetic variants induce instability of MED, leading to disrupted DNA occupancy, altered chromatin interaction, and subsequent transcriptional dysregulation of critical downstream genes, including master regulatory transcription factors ...

TDP1 deficiency sensitizes human cells to base damage via distinct topoisomerase I and PARP mechanisms with potential applications for cancer therapy [PDF]

open access: yes, 2013
Base damage and topoisomerase I (Top1)-linked DNA breaks are abundant forms of endogenous DNA breakage, contributing to hereditary ataxia and underlying the cytotoxicity of a wide range of anti-cancer agents.

Mechanical Cues Regulate Cargo Sorting and Export at the Golgi

open access: yesAdvanced Science, EarlyView.
A pathway is identified linking extracellular matrix stiffness to secretion via Src–FAK–AMPK–GBF1 signaling. Golgi‐localized GBF1 acts as a mechanotransducer whose phosphorylation controls post‐Golgi cargo sorting toward secretion or lysosomal degradation.

Serine/Threonine Kinase 33 as a Novel Target of Bufalin in Treatment of Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study identified that STK33 may serve as a target of Bufalin, which induces the degradation of STK33 and inhibits the growth of TNBC. Furthermore, STK33 is highly expressed in TNBC and enhances TNBC cell proliferation by phosphorylating and stabilizing CCAR1.

αCP binding to a cytosine-rich subset of polypyrimidine tracts drives a novel pathway of cassette exon splicing in the mammalian transcriptome. [PDF]

open access: yes, 2016
Alternative splicing (AS) is a robust generator of mammalian transcriptome complexity. Splice site specification is controlled by interactions of cis-acting determinants on a transcript with specific RNA binding proteins.

Real‐Time Tracking of ASCT2‐Mediated Glutamine Uptake in Living Tumors With a Bioorthogonal Bioluminescent Probe

open access: yesAdvanced Science, EarlyView.
A bioluminescent probe, BLGLN, comprising BL568 and ASCT2‐uptaken AA201, enables real‐time monitoring and evaluation of ASCT2‐mediated glutamine uptake rates in living tumors via Staudinger ligation, aiding tumor metabolism studies and targeted therapeutics.

KLK1 as an Epithelial‐Specific Brake Inhibits Colorectal Tumorigenesis by Suppressing B1R‐Mediated Fibroblast Phenotypic Transition

open access: yesAdvanced Science, EarlyView.
KLK1 downregulation disrupts the intestinal mucosal barrier and impairs kallikrein‐kinin signaling, thereby reducing Lys‐des‐Arg9‐BK production. This enhances B1R activation on ADAMDEC1⁺ fibroblasts, promoting inflammation and extracellular matrix (ECM) remodeling. The resulting iCAFs promote colorectal cancer progression, highlighting a novel KLK1‐B1R

Transcription of satellite DNAs in insects [PDF]

open access: yes, 2011
Chromatin condensation is an important regulatory mechanism of gene silencing as well as gene activation for the hundreds of functional protein genes harbored in heterochromatic regions of different insect species.

Novel Evolutionarily Conserved Oncogene COA4 is Driven by KRAS Mutant and Promotes Cancer Metastasis Through Dual Mitochondrial Metabolism‐Dependent and ‐Independent Mechanisms

open access: yesAdvanced Science, EarlyView.
In KRAS‐mutant tumors, KRAS transcriptionally upregulates COA4 via the PI3K/AKT/E2F1 axis, promoting metastasis. Mechanistically, COA4 enhances tumor cell migration through dual pathways: within mitochondria, it boosts oxidative phosphorylation; in the cytoplasm, it binds and activates CDC42 to stimulate pseudopodia formation.
