Bivariate Genomic Footprinting Detects Changes in Transcription Factor Activity

open access: yesCell Reports, 2017
In response to activating signals, transcription factors (TFs) bind DNA and regulate gene expression. TF binding can be measured by protection of the bound sequence from DNase digestion (i.e., footprint).

Nothing Besides Remains: Preserving the Scientific and Cultural Value of Paleontological Resources in the United States [PDF]

open access: yes, 2005
Receptor occupancy assessed by Positron Emission Tomography (PET) can provide important translational information to help bridge information from one drug to another or from animal to man.

cMet and fas receptor interaction inhibits death-inducing signaling complex formation in endothelial cells [PDF]

open access: yes, 2005
Fas receptor is constitutively expressed on endothelial cells; however, these cells are highly resistant to Fas-mediated apoptosis. In this study, we examined death-inducing signaling complex (DISC) formation in endothelial cells after Fas receptor ...

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

open access: yesFEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

Structural basis of frizzled 7 activation and allosteric regulation

open access: yesNature Communications
Frizzleds (ten paralogs: FZD1-10) belong to the class F of G protein-coupled receptors (GPCRs), which remains poorly understood despite its crucial role in multiple key biological functions including embryonic development, stem cell regulation, and ...

Molecular basis for allosteric agonism and G protein subtype selectivity of galanin receptors

open access: yesNature Communications, 2022
The basis for the diverse peptide-binding modes and the G protein selectivity of peptide GPCRs remains elusive. Here, the authors offer a structural basis for allosteric-like agonism and G protein selectivity of a neuropeptide GPCR, galanin receptor.

A chimeric virus-based probe unambiguously detects live circulating tumor cells with high specificity and sensitivity

open access: yesMolecular Therapy: Methods & Clinical Development, 2021
The current methods for detecting circulating tumor cells (CTCs) suffer from several drawbacks. We report a novel method that is based on a chimeric virus probe and can detect CTCs with extremely high specificity and sensitivity. Moreover, it exclusively

Exposure to Endocrine Disruptors and Nuclear Receptors Gene Expression in Infertile and Fertile Men from Italian Areas with Different Environmental Features [PDF]

open access: yes, 2015
Internal levels of selected endocrine disruptors (EDs) (i.e., perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), di-2-ethylhexyl-phthalate (DEHP), mono-(2-ethylhexyl)-phthalate (MEHP), and bisphenol A (BPA)) were analyzed in blood/serum of ...

Biophysical analysis of angiotensin II and amyloid‐β cross‐interaction in aggregation and membrane disruption

open access: yesFEBS Letters, EarlyView.
Angiotensin II (AngII), a neuropeptide, interacts with amyloid‐β (Aβ), a key player in Alzheimer's disease. This study reveals that AngII reduces Aβ aggregation and membrane disruption in vitro. Biophysical assays and molecular modeling suggest AngII binds disordered Aβ forms, potentially modulating early amyloidogenic events and contributing to ...
