Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

The relation between classical and quantum electrodynamics [PDF]

open access: yes, 2008
In this article it is presented the idea that quantum electrodynamics presents intrinsic limitations in the description of physical processes that makes it impossible to recover from it the type of description we have with classical electrodynamics.

Use of C4d as a diagnostic tool to classify membranoproliferative glomerulonephritis

open access: yesNefrología, 2017
Background: Membranoproliferative glomerulonephritis (MPGN type I, II and III) was reclassified in 2013 as MPGN and C3 glomerulopathy (C3G) based on the complement system activation mechanism.

FUNCTIONAL ACTIVITY OF COMPLEMENT CLASSIC WAY ACTIVATION COMPONENTS AND ART1CULAS DAMAGE IN RHEUMATOID ARTRITIS

open access: yesНаучно-практическая ревматология, 2000
A relationship between X - ray joints changes and functional activity of classical pathway complement components in R4 was investigated. 31 patients with the moderate activity ofRA (ARA 1987) have been examined. Disease duration was 4,5lyear±3,84 (SD). X-

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

open access: yesFEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Mechanisms of pre-mRNA splicing: classical versus non-classical pathways.

open access: yesHistology and histopathology, 1998
Expression of genetic information proceeds through two major biological events, transcription and translation. However, in eukaryotic cells, the primary transcript (pre-mRNA) is not the template that the translational apparatus scans through, in order to produce the corresponding protein. Pre-mRNAs undergo several modifications (cap site addition, poly

Factor H as a regulator of the classical pathway activation

open access: yesImmunobiology, 2012
C1q, the first subcomponent of the classical pathway, is a charge pattern recognition molecule that binds a diverse range of self, non-self and altered self ligands, leading to pro-inflammatory complement activation. Although complement is required for tissue homeostasis as well as defence against pathogens, exaggerated complement activation can be ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Surface stabilization determines a classical: fersus non-classical nucleation pathway during particle formation

open access: yes, 2016
Particle formation can occur by way of a classical or non-classical nucleation pathway. We show that during the bottom-up synthesis of cobalt particles the degree of particle surface stabilization determines the formation pathway.
