Neuroglobin regulates autophagy through mTORC1/RAPTOR/ULK-1 pathway in human neuroblastoma cells [PDF]
Scientific ReportsNeuroglobin (NGB) is a hexacoordinated hemeprotein mainly expressed in neurons. Following its upregulation and mitochondrial localization, NGB plays a pro-survival role against neuronal stress.

Theoretical Study on the Effective Magnetic Moments of Some Hemeproteins [PDF]
Progress of Theoretical Physics Supplement, 1961 It is pointed out that the measurement of the static magnetic susceptibilities over a wide temperature range will be able to the detailed information about the electronic structure of the paramagnetic heme derivatives. On the basis of the data given by the electron paramagnetic resonance experiment, formulas for the temperature dependence of the ...

Regulation of the expression of ferrochelatase in a murine model of diabetes mellitus type I [PDF]
Biochemistry and Biophysics ReportsBackground: Diabetes produces changes on cellular hemeprotein metabolism. The last enzyme of heme biosynthetic pathway is ferrochelatase (FECH), an enzyme that catalyzes the insertion of ferrous ion into protoporphyrin IX to produce heme. The aim of this
