EGFR protein, human
This protein is expressed in a variety of tissues and is often overexpressed or mutated in many types of cancer, making it an important target for cancer therapies.
EGFR protein studies are crucial for understanding its structure, function, and signaling pathways, as well as developing new therapeutic strategies.
Researchers can leverage PubCompare.ai, an AI-driven research platform, to optimize their EGFR protein experiments by exploring protocols from literature, pre-prints, and patents, and utilizing AI-powered comparisons to identify the best methodologies and products.
This can enhance research reproducibility and efficiency, making PubCompare.ai a one-stop solution for EGFR protein studies.

Example 17
The gD glycoprotein of HSV was modified to mediate viral entry via the EGFR receptor and engineered to encode for FAP-CD3. To test the ability of a retargeted ONCR-virus that encodes FAP-CD3 to induce tumor killing, 5×106 A431 cells are implanted subcutaneously into the right flank Nude mice. When the flank tumors reach ˜100 mm3, mice are injected intravenously with a single dose or ONCR-EGFR-(FAP-CD3) at 1×106 PFU; 3×106 PFU; 1×107 PFU, or vehicle (PBS). Tumor measurements are recorded every 2 to 3 days. Tumor growth inhibition is calculated against vehicle control treated cohort.

According to the above-mentioned method for measuring kinase inhibitory activity, the inhibitory activity of the active compounds on other multiple kinases was measured to characterize the kinase selectivity of active inhibitors.
The results showed that the active compound 6i could effectively inhibit the PDGFRα and PDGFRβ kinases at the concentration of 100 nM, wherein the inhibition rate could be over 100%, but had relatively weak inhibitory activity on other kinases, indicating good kinase selectivity.
Example 20
240 cell lines representative of multiple cancer indications with known alterations in the MAPK pathway, including KRAS, NRAS, HRAS, NF1, EGFR, BRAF and CRAF mutations, were seeded overnight in 386-well plates, then treated with a 9-point dose response of exemplary MEK inhibitors (starting dose of 100 nM and 3-fold dilution) for 5 days. Cell viability was determined using a Cell Titer Glo (CTG) assay. Percent inhibition was calculated for all compounds utilizing staurosporine (1000 nM) treatment as a measure of maximal inhibition. IC50 and area under the curve (AUC) values were determined by fitting a variable slope, four parameters curve to the compound concentration to percent inhibition relationship.
Compared to RAS/RAF wild-type cell lines, increased sensitivity to MEK inhibitors, such as I-2, was observed in cell lines with KRAS, NRAS, BRAF Class I and III mutations, as well as CRAF-alterations (both CRAF mutations and fusions). Cell lines with mutations in PIK3CA, PTEN, NF1, EGFR and HRAS showed similar sensitivity to MEK inhibition to RAS/RAF wild-type cell lines.

In this Example, the dose response of mAbXcite-cetuximab was studied. The present study utilized mAbXcite-cetuximab in which the conjugation utilized reductive amination (direct) chemistry, a 5-mer oligomer, and a load of about 3 oligomers per antibody.
In this Example, 7 week old female nude mice were implanted SC with 2.5×106 HCT-116 cells (HCT-116 is a human KRAS mutant colorectal cancer cell line). When tumor volume wan in the range of 51-80 mm3 mice were randomly divided into groups (9 mice/group) and treated with IVIG (as a source for anti-β-1,6-glucan antibodies) followed 2 hours later by vehicle control, cetuximab or mAbXcite EGFR. The dosing was determined by the half-life and was twice weekly. Various doses were assessed: 5, 10, 15 mg/kg for each antibody. Tumor volume was assessed by caliper measurement twice weekly. Body weight was monitored twice weekly. Mice were euthanized after tumors reached a volume of 2000 mm3 or if their body weight dropped by more than 15%.
Analysis of data collected form this experiment was performed. Tumor volume was calculated based on the following formula: TV (mm3)={length (mm)×width (mm)2}/2. Results are shown in
