Identifying prognostic targets in metastatic prostate cancer beyond AR

open access: yesFEBS Open Bio, EarlyView.
Genome‐wide functional screens combined with a large gene expression database and clinical outcomes can identify new therapeutic vulnerabilities in prostate cancer. Eight potentially druggable targets demonstrated strong dependency in cell lines, were associated with worse prognosis clinically, and showed evidence of protein expression in prostate ...

Orotic Aciduria [PDF]

open access: yes, 2018
Orotic acid is an intermediate found in the pathway for pyrimidine synthesis. The mitochondrial enzyme dihydroorotate dehydrogenase (DHODH) catalyzes the production of orotic acid by the conversion of the compound dihydroorotate to orotic acid.

A Visible Light‐Responsive Hydrogel to Study the Effect of Dynamic Tissue Stiffness on Cellular Mechanosensing

open access: yesAdvanced Functional Materials, EarlyView.
A visible light‐responsive polyacrylamide‐azobenzene hydrogel enables safe, reversible stiffness control for studying cell mechanobiology without harmful UV exposure. This approach reveals stem cells respond rapidly to mechanical changes, showing altered shape and protein distribution within one hour.

Expanding a fluorescent RNA alphabet: synthesis, photophysics and utility of isothiazole-derived purine nucleoside surrogates. [PDF]

open access: yes, 2017
A series of emissive ribonucleoside purine mimics, all comprised of an isothiazolo[4,3-d]pyrimidine core, was prepared using a divergent pathway involving a key Thorpe-Ziegler cyclization.

Interaction of Oligonucleotides with Gold Nanoparticles: Factors Beyond Electrostatic and Van‐Der Waals Forces

open access: yesAdvanced Materials Interfaces, EarlyView.
The formation of stable clusters of gold nanoparticles with oligonucleotides at different solution conditions is explored. DNA base homogeneity and strand directionality influence the binding with gold nanoparticles leading to interesting clustering behavior that can be relevant for SERS applications.

The Ability of Cyanobacterial Cells to Restore UV-B Radiation Induced Damage to Photosystem II is Influenced by Photolyase Dependent DNA Repair [PDF]

open access: yes, 2013
Damage of DNA and Photosystem-II are among the most significant effects of UV-B irradiation in photosynthetic organisms. Both damaged DNA and Photosystem-II can be repaired, which represent important defense mechanisms against detrimental UV-B effects ...

STUDIES IN PYRIMIDINE METABOLISM [PDF]

open access: yesJournal of Biological Chemistry, 1920
By partial hydrolysis of yeast nucleic acid, preparations containing pyrimidines as the only nitrogenous constituents were prepared and administered to rabbits. Uracil nucleoside when administered per os, subcutaneously or intraperitoneally caused an increased excretion of urea often much more than enough to account for the nitrogen administered.

Recent Developments in Radical Mediated Synthesis of Organostannanes.

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract The present review aims to provide an overview of the recent developments in the preparation of aryl‐ or alkenyl stannanes via carbon‐ and tin‐centered radicals enabling chemists to synthesize organostannyl derivatives with high efficiency and under mild conditions.
