Tyrosine-Dependent Phenotype Switching Occurs Early in Many Primary Melanoma Cultures Limiting Their Translational Value

Frontiers in Oncology, 2021
The use of patient-derived primary cell cultures in cancer preclinical assays, including drug screens and genotoxic studies, has increased in recent years.

Performance of piglets in response to the standardized ileal digestible phenylalanine and tyrosine supply in low-protein diets

Animal, 2014
Reducing the CP level of the diet allows for a reduction in N excretion without limiting performance as long as the amino acid (AA) requirements are covered. The availability of crystalline AA has permitted for a considerable reduction in the CP level of

Discovery of a Novel, Potent, and Src Family-selective Tyrosine Kinase Inhibitor

Journal of Biological Chemistry, 1996
Here, we have studied the activity of a novel protein-tyrosine kinase inhibitor that is selective for the Src family of tyrosine kinases. We have focused our study on the effects of this compound on T cell receptor-induced T cell activation, a process ...

Effect of large neutral amino acids treatment on blood phenylalanine, tyrosine, and tryptophan levels in adolescent and young adult PKU patients

Trends in Pediatrics
Objective: We aimed to evaluate the change in phenylalanine (Phe), Tyrosine (Tyr), and Tryptophan (Trp) blood levels in classical PKU patients treated with large neutral amino acids (LNAA) supplementation.

Role of Bruton’s tyrosine kinase in B cells and malignancies

Molecular Cancer, 2018
Bruton’s tyrosine kinase (BTK) is a non-receptor kinase that plays a crucial role in oncogenic signaling that is critical for proliferation and survival of leukemic cells in many B cell malignancies. BTK was initially shown to be defective in the primary

Serum tryptophan, kynurenine, phenylalanine, tyrosine and neopterin concentrations in 100 healthy blood donors

Pteridines, 2015
Formation of neopterin, a biomarker of the activated human immune system, is linked with tryptophan (TRP) and phenylalanine (PHE) metabolism. To obtain normal values, in this study, serum concentrations of neopterin as well as of TRP, PHE and their ...

Anlotinib: a novel multi-targeting tyrosine kinase inhibitor in clinical development

Journal of Hematology & Oncology, 2018
Anlotinib is a new, orally administered tyrosine kinase inhibitor that targets vascular endothelial growth factor receptor (VEGFR), fibroblast growth factor receptor (FGFR), platelet-derived growth factor receptors (PDGFR), and c-kit.

Phosphorylation of (Ser 291) in the linker insert of Syk negatively regulates ITAM signaling in platelets

Platelets
Receptor-induced tyrosine phosphorylation of spleen tyrosine kinase (Syk) has been studied extensively in hematopoietic cells. Metabolic mapping and high-resolution mass spectrometry, however, indicate that one of the most frequently detected ...

Hawkinsinuria With Direct Hyperbilirubinemia in Egyptian-Lebanese Boy

Frontiers in Pediatrics, 2019
Tyrosinemia type III is the rarest type of tyrosinemia, because of a mutation in 4-OH-phenylpyruvate dioxygenase (HPD). This causes two different types of diseases with different modes of inheritance: tyrosinemia type III and hawkinsinuria. Hawkinsinuria
