Pemetrexed's mechanism of action: After transfer into cells, pemetrexed undergoes polyglutamylation. Both the nonglutamated and as the polyglutamated forms are able to inhibit DHFR, GARFT, and TS. Figure according to36. AMP, adenosine monophosphate; DHF, dihydrofolate; DHFR, dihydrofolate reductase; dTMP, deoxythymidine monophosphate; dUMP, deoxyuridine monophosphate; FPGS, folylpoly-γ-glutamate synthetase; GARFT, glycinamide ribonucleotide formyltransferase; GGH, gamma-glutamyl hydrolase; Gln, glutamine; GMP, guanosine monophosphate; IMP, inosine monophosphate; PCFT, proton-coupled folate transporter; PPRP, phosphoribosyl pyrophosphate; RFC, reduced folate carrier; THF, tetrahydrofolate; TS, thymidylate synthase.

A to H, Examples of IHC for FPGS and TS in MPM samples with different protein expressions. A to D, IHC with an antibody against FPGS: (A) hepatocellular carcinoma was used as positive control; (B) weakly stained MPM sample (H-score of 90); (C) moderately stained MPM sample (H-score of 170); and (D) strongly stained MPM sample (H-score of 290). E to -H, IHC with an antibody against TS (dilution 1:10); (E) colorectal carcinoma was used as positive control; (F) weakly stained MPM sample (H-score of 90); (G) moderately stained MPM sample (H-score of 170); and (H) strongly stained MPM sample (H-score of 290). Magnification 1:400. IHC, immunohistochemistry; FPGS, folylpoly-γ-glutamate synthetase; TS, thymidylate synthase; MPM, malignant pleural mesothelioma.
