To confirm the clin. significance of NF-κB and JNK protein expression from exptl. identified candidates for predicting prognosis for patients with 5-FU treatment, we evaluated the protein expression of surgically removed specimens. A total of 79 specimens were obtained from 30 gastric and 49 colorectal cancer patients who underwent R0 resection followed by postoperative 5-FU based adjuvant chemotherapy. Immunohistochem. examinations of NF-κB and JNK on tissue microarrays (TMAs) revealed that significantly shorter time-to-relapse (TTR) in both NF-κB(+) and JNK(-) subgroups in both gastric (NF-κB(+), p = 0.0002, HR11.7, 95%CI3 3.2-43.4; JNK(-), p = 0.0302, HR4.4, 95%CI 1.2-16.6) and colon (NF-κB(+), p = 0.0038, HR36.9, 95%CI 3.2-426.0; JNK(-), p = 0.0098, HR3.2, 95%CI 1.3-7.7) cancers. These protein expression patterns also show strong discriminately power in gastric cancer patients for overall survival rate, suggesting a potential utility as prognostic or chemosensitivity markers. Baseline expression of these proteins using gastric cancer cell lines demonstrated the reciprocal patterns between NF-κB and JNK, while 5-FU exposure of these cell lines only induced NF-κB, suggesting that NF-κB plays a dominant role in the response to 5-FU. Subsequent siRNA experiments confirmed that gene knockdown of NF-κB increased 5-FU-specific sensitivity, whereas that of JNK did not affect the chemosensitivity. These results suggest that the expression of these proteins may aid in the decisions involved with adjuvant chemotherapy for gastrointestinal tract cancers. In the experiment, the researchers used many compounds, for example, 1-((2R,3R,4S,5R)-3,4-Dihydroxy-5-methyltetrahydrofuran-2-yl)-5-fluoropyrimidine-2,4(1H,3H)-dione (cas: 3094-09-5Application of 3094-09-5).
1-((2R,3R,4S,5R)-3,4-Dihydroxy-5-methyltetrahydrofuran-2-yl)-5-fluoropyrimidine-2,4(1H,3H)-dione (cas: 3094-09-5) belongs to tetrahydrofuran derivatives. Solid acid catalysis, and the advantages often associated with their use, have been proved equally efficient for the synthesis of tetrahydrofurans or furans. Oxidations have also proved to be valuable and efficient approaches to chiral tetrahydrofuran derivatives.Application of 3094-09-5
