Quantitation of 55 Common Human Plasma Proteins in Healthy Young Adults and Correlation with Body Mass Index and Dietary Patterns [PDF]

open access: yes, 2010
Plasma biomarkers are a useful tool for monitoring dietary exposures and the development of chronic disease. Measuring multiple biomarkers at once provides a more complete characterization of phenotype than measuring single markers.

Tumor Cell Complementation Groups Based on Myogenic Potential: Evidence for Inactivation of Loci Required for Basic Helix-Loop-Helix Protein Activity [PDF]

open access: yesMolecular and Cellular Biology, 1996
Basic helix-loop-helix (bHLH) proteins mediate terminal differentiation in many lineages. By using the bHLH protein MyoD, which can dominantly activate the myogenic differentiation program in numerous cell types, we demonstrated that recessive defects in bHLH protein function are present in human tumor lines. In contrast to prior work with primary cell

Human complement factor H [PDF]

open access: yes, 1986
We isolated cDNA clones coding for the functionally important tryptic N-terminal38- kDa fragment of human complement control protein factor H using polyclonal and monoclonal antibodies to screen a human liver cDNA library cloned in a bacterial expression

Characterization of the lymphocyte membrane receptor for factor H (β1H- globulin) with an antibody to anti-factor H idiotype [PDF]

open access: yes, 1982
Antibody to the binding site (idiotype) of anti-factor H was shown to have specificity for both B lymphocyte membrane H receptors and C3b. Goat F(ab’)(2) anti-human H was purified by absorption and elution from H agarose and used for rabbit immunization ...

Interaction of S-protein of complement with thrombin and antithrombin III during coagulation. Protection of thrombin by S-protein from antithrombin III inactivation.

open access: yesJournal of Biological Chemistry, 1986
S-protein, the inhibitor in plasma of the membrane attack complex of complement, appears to have a second function in coagulation. S-protein during clotting enters into a trimolecular complex with thrombin and antithrombin III (ATIII). Functionally, S-protein in the presence of low concentrations of heparin, protects thrombin from inactivation by ATIII.

Buoyancy regulation and aggregate formation in Amoebobacter purpureus from Mahoney lake [PDF]

open access: yes, 1992
The meromictic Mahoney Lake (British Columbia, Canada) contains an extremely dense layer of purple sulfur bacteria (Amoebobacter purpureus). The buoyant density of Amoebobacter cells grown in pure culture at saturating light intensity was significantly ...

Detection of Sulfoquinovosidase Activity in Cell Lysates Using Activity‐Based Probes

open access: yesAngewandte Chemie, Volume 136, Issue 26, June 21, 2024.
The development of activity‐based probes targeting the active site nucleophile of glycoside hydrolase family 31 sulfoquinovosidases is described. The probes are shown to bind covalently by structural biology, mass spectrometry and Cy5 in‐gel fluorescence, are selective for sulfoquinovosidases in whole bacterial cell lysates, and are used to monitor ...

Development of Efficient Covalent Inactivators of a Fungal Aspartate Semialdehyde Dehydrogenase

open access: yesDrug Development Research, Volume 86, Issue 3, May 2025.
ABSTRACT Aspartate semialdehyde dehydrogenase (ASADH) catalyzes the second step in the fungal pathway towards the synthesis of threonine, isoleucine, and methionine, and it has been identified as a viable target for antifungal drug development. Our previous work produced a group of vinyl sulfones that function as irreversible covalent inactivators of ...

Lung‐Specific mRNA Delivery by Ionizable Lipids with Defined Structure‐Function Relationship and Unique Protein Corona Feature

open access: yesAdvanced Science, Volume 12, Issue 14, April 10, 2025.
A novel structure‐function relationship is identified for lung‐targeting ionizable lipids with nonpermanent charges. These lipids feature N‐methyl and secondary amine groups in their heads and three tails derived from epoxyalkanes, demonstrating superior pulmonary selectivity and efficiency.
