"Preliminary studies confirmed that sialoadenectomy reduced circulating EGF levels in nude mice (from 0.17 +/- 0.02 to 0.09 +/- 0.02 ng/ml), and that ip injection of 5 micrograms EGF raised EGF levels (the peak level of 91.7 +/- 3.3 ng/ml was achieved at 30 min, with a subsequent half-life of about 1 h)."
reach
"In the liver, EGF is upregulated in a rat model of liver fibrogenesis and in human cirrhotic liver tissues (7, 8), and a polymorphism in the human EGF gene that leads to increased EGF expression is associated with increased fibrosis and cirrhosis progression in patients with chronic hepatitis C (9)."

"Furthermore, the area of EGF receptor positive cells in the wound surface of the EGF nanogroup was higher than that of the EGF group, with the results demonstrating that EGF nanoparticles upregulated the expression of EGF receptors in wound surface cells, promoted wound surface healing, and had better efficacy than EGF."

"EGF expression is associated with progression of cirrhosis,13 and in animal models, overexpression of EGF in liver tissue leads to formation of HCC.33 34 In humans, a functional single nucleotide polymorphism in the EGF gene increases EGF levels in liver tissue, and this single nucleotide polymorphism is also associated with increased risk for HCC.14 Among cirrhotic patients, those with high EGF expression in their liver tissue have the poorest overall survival."
reach
"EGF and Notch null mutations are recessive, thatis, a half-dosage is sufficient for patterning (+/-labels); this and an EGF overexpression line with known EGF levels (JU1107 label; see XREF_TABLE for a list of the experimental lines referred in this study) delimit the central wild-type region."

"The STAT dimers translocate to the nucleus, bind response elements and activate transcription of genes.JAK, Janus kinase; P, phosphate; STAT, signal transducer and activator of transcription.ceptors for epidermal growth factor (EGF), platelet derived growth factor (PDGF) and colony stimulating factor 1 (CSF-l)] phosphorylate members of the STAT family."
reach
"These results indicate that LTC4 mediated CysLT1 signaling may regulate the EGF induced second wave of Rac1 activation.As described above, Tiam1 is responsible for the EGF induced second wave of Rac1 activation, and EGF increases Tiam1 expression in terms of both mRNA and protein levels."
