Solid Lipid Nanoparticles Loaded with Glucocorticoids Protect Auditory Cells from Cisplatin-Induced Ototoxicity
(MDPI, 2019-09-14)
Cisplatin is a chemotherapeutic agent that causes the irreversible death of auditory sensory cells, leading to hearing loss. Local administration of cytoprotective drugs is a potentially better option co-therapy for ...
Integration Through Separation - The Role of Lateral Membrane Segregation in Nutrient Uptake
(Frontiers Media, 2019-06-25)
Nutrient transporters are prominent and ubiquitous components of the plasma membrane in all cell types. Their expression and regulation are tightly linked to the cells' needs. Environmental factors such as nutrient starvation ...
Dermal Delivery of the High-Molecular-Weight Drug Tacrolimus by Means of Polyglycerol-Based Nanogels
(MDPI, 2019-08)
Polyglycerol-based thermoresponsive nanogels (tNGs) have been shown to have excellent skin hydration properties and to be valuable delivery systems for sustained release of drugs into skin. In this study, we compared the ...
Characterization of USP11 as a novel regulator of Hypoxia inducible factor a
(2019-11-27)
Adaptation to hypoxia is a puzzling and tightly regulated challenge. This adaptability involves a severe gene expression rewiring, which is mainly triggered by the Hypoxia Inducible transcription Factor (HIF). Canonically, ...
Molecular recognition between PCNA and proteins involved in DNA replication and repair: p15 and p12
(2019-12-19)
El antígeno nuclear de células en proliferación (PCNA) es un factor esencial en replicación y reparación de ADN en eucariotas. Forma un anillo homotrimérico que rodea y se desliza a lo largo del ADN, actuando como una ...
Structural study of CUG-repeating small RNAs complexed with silencing suppressor P19
(2014-02-24)
The study is focused on structural aspects of interaction between silencing suppressor p19 and CUG-repeating small RNAs. The work involves crystal structure determination of a protein-unbound RNA form and RNA fragments of ...
Magnetic Cross-Linked Enzyme Aggregates (mCLEAs) of Candida antarctica Lipase: An Efficient and Stable Biocatalyst for Biodiesel Synthesis
(Public Library Science, 2014-12-31)
Enzyme-catalyzed production of biodiesel is the object of extensive research due to the global shortage of fossil fuels and increased environmental concerns. Herein we report the preparation and main characteristics of a ...
Structural Basis for Feed-Forward Transcriptional Regulation of Membrane Lipid Homeostasis in Staphylococcus aureus
(Public Library of Science, 2013-01-03)
The biosynthesis of membrane lipids is an essential pathway for virtually all bacteria. Despite its potential importance for the development of novel antibiotics, little is known about the underlying signaling mechanisms ...
RARRES3 suppresses breast cancer lung metastasis by regulating adhesion and differentiation
(Wiley Blackwell, 2014-07)
In estrogen receptor-negative breast cancer patients, metastatic relapse usually occurs in the lung and is responsible for the fatal outcome of the disease. Thus, a better understanding of the biology of metastasis is ...
Optimal Resting-Growth Strategies of Microbial Populations in Fluctuating Environments
(Public Library of Science, 2011-04-15)
Bacteria spend most of their lifetime in non-growing states which allow them to survive extended periods of stress and starvation. When environments improve, they must quickly resume growth to maximize their share of limited ...
