Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

open access: yesMolecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Optimization of Nd-Doped LMA Fibers for High-Power Laser Emission Near 915 nm

open access: yesIEEE Photonics Journal
We report on the development of low numerical aperture (NA) Nd-doped large mode area (LMA) fibers with optimized core/clad geometry to achieve high-power laser emission near 915 nm while maintaining near diffraction-limited output beam.

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

open access: yesMolecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

open access: yesMolecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Experimental studies of exotic transitions in high-Z few-electron ions [PDF]

open access: yes, 2009
A novel experimental approach for studying exotic transitions in few-electron high-Z ions was developed. In this approach, few-electron ions with selectively produced single K-shell holes are used for the investigation of the transition modes that follow

Towards Gas-Phase Enzymes: Ion Chemistry for Introducing Selective Dissociation Pathways into Bio-ions

open access: yes, 2020
Tandem mass spectrometry has long been used as a tool to extract structural information from an analyte ion. However, the information obtained in a tandem mass spectrometry experiment is dependent on both the ion type subjected to activation and the type

Profiling neoadjuvant therapy response in rectal cancer using meta‐analysis of publicly available transcriptomic RNA‐seq datasets

open access: yesMolecular Oncology, EarlyView.
This study integrates publicly available transcriptomic datasets to identify molecular signatures associated with response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer. By analyzing a combination of multiple cohorts with bioinformatics approaches, we reveal biological pathways and immune‐related features that may improve ...

Impact of a transient neonatal visual deprivation on the development of the ventral occipito-temporal cortex in humans

open access: yesNature Communications
How does sensory experience shape the development of the visual brain? To answer this eluding question, we examine brain responses to visual categories in a rare group of cataract-reversal individuals who experienced a short transient period of early ...
