Requirement for ω and (ω–1)-hydroxylations of fatty acids by human cytochromes P450 2E1 and 4A11
Journal of Lipid Research, 1999 Human liver microsomes and recombinant human P450 have been used as enzyme source in order to better understand the requirement for the optimal rate of ω and (ω–1)-hydroxylations of fatty acids by cytochromes P450 2E1 and 4A.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Leukemia is the most common childhood cancer in Mexico, and acute lymphoblastic leukemia (ALL) is the most frequent subtype. Exposure to high concentrations of benzene has been associated with ALL incidence, particularly in urban areas. This study evaluated the relationship between distance to benzene emission sources and the number

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

The Rieske/cytochrome b complex of Heliobacteria
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2008 Heliobacteria have a Rieske/cytochrome b complex composed of a Rieske protein, a cytochrome b(6,) a subunit IV and a di-heme cytochrome c. The overall structure of the complex seems close to the b(6)f complex from cyanobacteria and chloroplasts to the exception of the di-heme cytochrome. We show here by biochemical and biophysical studies that a heme c(

Molecular Oncology, EarlyView.Interferon type 1 (IFN‐1) production and signaling is associated with the acquisition of therapy resistance, following chronic DNA damage, via Interferon‐related DNA damage resistance signature (IRDS) gene expression. An alternative, DNA damage‐independent role of sustained IFN‐1 mediated resistance was identified and characterized by the emergence of ...
