Electron Paramagnetic Resonance and Electron Spin Echo Studies of Co2+ Coordination by Nicotinamide Adenine Dinucleotide (NAD+) in Water Solution [PDF]

open access: yes, 2013
Co(2+) binding to the nicotinamide adenine dinucleotide (NAD(+)) molecule in water solution was studied by electron paramagnetic resonance (EPR) and electron spin echo at low temperatures. Cobalt is coordinated by NAD(+) when the metal is in excess only,

Positive Chemotactic Flasklike Colloidal Motors Propelled by Rotary FoF1-ATP Synthases

open access: yesResearch
Living microorganisms can perform directed migration for foraging in response to a chemoattractant gradient. We report a biomimetic strategy that rotary FoF1-ATPase (adenosine triphosphatase)-propelled flasklike colloidal motors exhibit positive ...

Effects of DTX3L on the cell proliferation, adhesion, and drug resistance of multiple myeloma cells

open access: yesTumor Biology, 2017
Cell adhesion–mediated drug resistance is an important factor that influences the effects of chemotherapy in multiple myeloma. DTX3L, a ubiquitin ligase, plays a key role in cell-cycle-related process.

Calcium-RasGRP2-Rap1 signaling mediates CD38-induced migration of chronic lymphocytic leukemia cells

open access: yesBlood Advances, 2018
: CD38 is a transmembrane exoenzyme that is associated with poor prognosis in chronic lymphocytic leukemia (CLL). High CD38 levels in CLL cells are linked to increased cell migration, but the molecular basis is unknown.
