Aligned Fibronectin Microenvironment Temporally Facilitates Profibrotic Fibroblast Activation via Integrin α5β1

Advanced Science, EarlyView.
Compared to a healthy random nanofibrous fibronectin microenvironment, a fibrotic aligned nanofibrous fibronectin microenvironment employs a specific integrin, α5β1 integrin, to activate early pro‐fibrotic fibroblast behaviors and later fibrotic fibroblast tissue formation with cell/F‐actin alignment, α‐SMA expression, and cell‐driven aligned ...

Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System

Advanced Science, EarlyView.
Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...

Programmable RNA N6,2´‐O‐Dimethyladenosine Editing

Advanced Science, EarlyView.
ABSTRACT N6,2’‐O‐dimethyladenosine (m6Am) is a prevalent RNA modification located at the first transcribed nucleotide adjacent to the 5′ cap of mRNAs, where it has been implicated in gene regulation. However, the lack of methods for precise, transcript‐specific manipulation of m6Am has limited its functional dissection.

Identification of subunit contact sites on the .alpha.-subunit of lutropin

Biochemistry, 1991
Peptides corresponding to the entire sequence of the alpha-subunit of the human glycoprotein hormones were synthesized by using standard solid-phase procedures. Purified peptides were incubated in the presence of alpha- and beta-subunits of bovine lutropin, and subunit recombination was monitored by difference spectroscopy, reverse-phase high-pressure ...

The reaggregation of purified subunits of alpha-crystallin

Experimental Eye Research, 1973
Abstract Ultracentrifuge studies have been carried out with reaggregated macromolecules obtained from purified subunits of low MW calf lens alpha-crystallin. The subunits were isolated by affinity chromotography with para-amino-phenyl mercuric acetate-Agarose columns followed by chromatography with DEAE-cellulose in 7 m urea.

II. Immunochemical studies on alpha crystallin subunits

Experimental Eye Research, 1972
Abstract Carboxymethylated alpha crystallin subunits yield a clearer separation of the acidic and basic subunit molecules than native alpha crystallin subunits. A minimum of four distinct subunit molecules could be observed in all fractionation procedures tested.

Kinetics of oxygen binding and subunit assembly for the hemoglobin alpha subunit

Biophysical Chemistry, 1992
A thorough kinetic characterization of the O2-binding and self-association reactions of alpha-subunits of human hemoglobin A has been performed. All of the rate constants for a five step reaction model linking the monomer-dimer reaction to the O2-binding steps have been determined for the first time.

A monosaccharide is bound to the sodium-pump .alpha.-subunit

Biochemistry, 1992
We have recently reported that the Na pump alpha-subunit has cytosolic-oriented oligosaccharides which were sensitive to cleavage by an enzyme specific for hydrolysis of N-linked glycans [Pedemonte et al. (1990) Proc. Natl. Acad. Sci. U.S.A. 87, 9789-9793].

Detection of the alpha-subunit of inhibin in trophoblastic neoplasia

Human Pathology, 1999
Placental trophoblasts are the primary source of serum inhibin during pregnancy. We sought to characterize inhibin immunolabeling in trophoblastic neoplasms and compare the results with those for established markers of trophoblastic differentiation. Formalin-fixed, paraffin-embedded tissues from three normal term placentas, 13 hydatidiform moles (HM ...
