FOXP3 Polymorphism and Upregulation of the CXCL12‐CXCR4‐SNAIL Axis with High Infiltration of M2TAM by STAT3/NFKB Pathways Influence the Survival of Cervical Cancer Patients

Advanced Biology, EarlyView.
This study highlights how cervical carcinoma progression is shaped by immune–tumor interactions within the TME. M2‐TAM infiltration, regulated through STAT3/NF‐κB and linked to CXCL12–CXCR4, promotes immune suppression, angiogenesis, and poor survival.

A Spatially Resolved View on the Aging Substantia nigra: An Exploratory Proteomic Study

Advanced Biology, EarlyView.
Although aging is the most important risk factor for several neurodegenerative diseases, the molecular effects of physiological aging are still understudied. By applying spatially‐resolved proteomic analyses of the human substantia nigra pars compacta, alterations in vesicular trafficking and mitochondrial proteins are observed, as well as reduced ...

Osteocytes under Mechanical Loading Regulate PC‐3 Cancer Cell–Mineral Interactions during Early‐Stage Metastasis to Bone

Advanced Biology, EarlyView.
In this study, Seaman et al. develop a co‐culture assay to examine interactions between prostate cancer cells and mineralized osteoblasts in a microfluidic platform. The authors collect conditioned media from static or flow‐stimulated osteocytes and demonstrate that mechanical loading of osteocytes regulates the growth of prostate cancer cells and ...

Conformation spaces of proteins

Proteins: Structure, Function, and Bioinformatics, 2001
We report a simple method for measuring the accessible conformational space explored by an ensemble of protein structures. The method is useful for diverse ensembles derived from molecular dynamics trajectories, molecular modeling, and molecular structure determinations. It can be used to examine a wide range of time scales.

Conformation of ribonuclease S-protein

Experientia, 1979
Ribonuclease S-protein exhibits a pH-dependent conformational transition between folded and unfolded states, and some unfolded S-protein persists up to pH 8. The histidine C2 proton resonance of the unfolded species was erroneously assigned by Bradbury et al. to histidine residue 119 of the folded species.

Conformational spectra — probing protein conformational changes

Biophysical Chemistry, 1999
Stafford [Biophys. J. 17 (1996) MP452] has shown that it is possible, using the analytical ultracentrifuge in sedimentation velocity mode, to calculate the molecular weights of proteins with a precision of approximately 5%, by fitting Gaussian distributions to g(s*) profiles so long as partial specific volume and the radial position of the meniscus are
