Pleiotropic physiological consequences of feedback-insensitive phenylalanine biosynthesis in Arabidopsis thaliana.

Plant J. 63(5) , 823-35, (2010)

A large proportion of plant carbon flow passes through the shikimate pathway to phenylalanine, which serves as a precursor for numerous secondary metabolites. To identify new regulatory mechanisms aff...

Concomitant tumor resistance: the role of tyrosine isomers in the mechanisms of metastases control.

Cancer Res. 72(5) , 1043-50, (2012)

Concomitant tumor resistance (CR) is a phenomenon in which a tumor-bearing host is resistant to the growth of secondary tumor implants and metastasis. Although previous studies indicated that T-cell-d...

Inhibitory effect of a two day fast on reactive oxygen species (ROS) generation by leucocytes and plasma ortho-tyrosine and meta-tyrosine concentrations.

J. Clin. Endocrinol. Metab. 86(6) , 2899-902, (2001)

ABSTRACT Since glucose intake acutely increases reactive oxygen species (ROS) generation by polymorphonuclear leucocytes (PMN) and mononuclear cells (MNC), we have now investigated whether a fast over...
