| Overexpression of epidermal growth factor receptor (EGFR)
plays a significant role in the development and metastasis
of many solid tumors. Strategies based on anti-EGFR
immunotoxins have shown promising results in several
studies, but immunogenicity of antibody and toxin moieties
is a limitation of this type of therapeutics. In the present
study, a novel humanized anti-EGFR immunotoxin (huscFv-
PE25) was developed by genetic fusing of a humanized
anti-EGFR single-chain variable fragment (huscFv) with a
modified Pseudomonas aeruginosa exotoxin A (PE25KDEL).
The reactivity and toxicity of this immunotoxin with tumor
cells were assessed by dot-blot, enzyme-linked
immunosorbent assay, and MTT procedures. Results of
enzyme-linked immunosorbent assay and dot-blot assay
indicated that the immunotoxin recognizes and efficiently
binds to EGFR-overexpressing tumor cells. MTT assay
showed a specific growth-inhibitory effect of huscFv-PE25
on EGFR-overexpressing A431 cells, without any inhibitory
effect on EGFR-negative cells. In conclusion, the results of
this study indicated that huscFv-PE25 can recognize and
exert an inhibitory effect on EGFR-overexpressing cancer
cells, despite its smaller size and lower immunogenicity.
This may provide a basis for the development of novel
clinical therapeutic agents against EGFR-overexpressing
tumor cells. |
