Affinity-based protein profiling identifies vitamin D3 as a heat shock protein 70 antagonist that regulates hedgehog transduction in murine basal cell carcinoma.

European journal of medicinal chemistry

Wen J, Hadden MK.
PMID: 34844141
Eur J Med Chem. 2021 Nov 20;228:114005. doi: 10.1016/j.ejmech.2021.114005. Epub 2021 Nov 20.

Vitamin D3 (VD3) is a seco-steroid that inhibits the Hedgehog (Hh) signaling pathway. Initial studies suggested its anti-Hh activity results from direct inhibition of Smoothened, a seven-transmembrane cell surface receptor that is a key regulator of the Hh signaling...

A recent workshop titled "Developing Models to Study Polymicrobial Infections," sponsored by the Dartmouth Cystic Fibrosis Center (DartCF), explored the development of new models to study the polymicrobial infections associated with the airways of persons with cystic fibrosis (CF)....

Note: Velocity map imaging the scattering plane of gas surface collisions.

The Review of scientific instruments

Hadden DJ, Messider TM, Leng JG, Greaves SJ.
PMID: 27802734
Rev Sci Instrum. 2016 Oct;87(10):106104. doi: 10.1063/1.4965970.

The ability of gas-surface dynamics studies to resolve the velocity distribution of the scattered species in the 2D scattering plane has been limited by technical capabilities and only a few different approaches have been explored in recent years. In...

Relatively little is known about Nubia's genetic landscape prior to the influence of the Islamic migrations that began in the late 1st millennium CE. Here, we increase the number of ancient individuals with genome-level data from the Nile Valley...

Tissue-specific control of CFTR endocytosis by Dab2: Cargo recruitment as a therapeutic target.

Communicative & integrative biology

Madden DR, Swiatecka-Urban A.
PMID: 23181163
Commun Integr Biol. 2012 Sep 01;5(5):473-6. doi: 10.4161/cib.21375.

Clathrin-mediated endocytosis dynamically regulates cell membrane abundance of CFTR and plays an essential role in CFTR-dependent Cl(-) conductance in fluid-transporting epithelia. It requires two closely related, but distinct processes: assembly of the clathrin coat and recruitment of cargo proteins...

A Control-Theoretic Assessment of Interventions During Drinking Events.

The replication stress response, which serves as an anticancer barrier, is activated not only by DNA damage and replication obstacles but also oncogenes, thus obscuring how cancer evolves. Here, we identify that oncogene expression, similar to other replication stress-inducing...
