"These deficiencies of formalin are more than tissue based penetration related issues as we have shown that formalin failed to preserve an EGF induced increase in the phosphorylation of EGFR Tyr1068 in suspension cells that are likely immediately fixed, thus indicating inadequate retention of phosphorylation due to the slow inhibition of phosphatase enzymes (XREF_FIG)."

"Increased Akt and rpS6 phosphorylation were observed in the CL 1-5 cells under the dcEF stimulation in the serum containing medium, in agreement with the results in the RTK assay described in section F. EGF stimulated CL 1-5 cells show significant EGFR (Tyr1068) phosphorylation compared to the control group, while neither CL 1-5 cells nor CL1-0 cells show EGFR Tyr1068 phosphorylation under the dcEF stimulation."

"Our previous results showed that PKG II could inhibit EGF-induced tyrosine 1068 phosphorylation of EGFR in gastric cancer cell line BGC-823 xref , raising the question whether PKG II can inhibit the phosphorylation of other tyrosine sites on EGF/EGFR and thereafter have a wide-range inhibition on EGF/EGFR-induced signal transductions and related biological activities of gastric cancer cells."
