CPT-11 (irinotecan or 7-ethyl-10[4-(1-piperidino)-1-piperidino] carbonyloxycamptothecin) is an anticancer agent in use for the treatment of colon cancer.
CONCLUSIONS NPRL2 overexpression enhances sensitivity to CPT-11 treatment in colon cancer cells, and it may serve as a molecular therapeutic agent to treat patients with CRC.
Determination of the presence of a K-ras mutation may predict survival in patients with progressive colon cancer after treatment with 5-fluorouracil who receive CPT-11.
Identification of the molecular determinants of 5-fluorouracil (5-FU) and irinotecan (CPT-11) efficacy and toxicity is critically important for the development of more efficient and less toxic treatment strategies for patients with colon cancer.
In an attempt to identify genes that are involved in resistance to SN38, the active metabolite of irinotecan (also known as CPT-11), we carried out DNA microarray profiling of matched HCT116 human colon cancer parental cell lines and SN38-resistant cell lines following treatment with SN38 over time.
In present investigation, we developed a novel hyaluronated cationic nanostructured lipid carrier (CNLCs) which contains CPT-11/irinotecan to target CD44 biomarker which commonly overexpresses on colon cancer.
In this study, the chemotherapeutic efficacy of dihydromyricetin (DMY) intervention on treatments involving irinotecan (CPT-11) or gemcitabine (GM) was evaluated in an AOM/DSS-induced colitis-associated colon cancer model and a Min (Apc Min/+) mice model.
KDM5c expression upregulation in colon cancer cells had significantly reduced L-OHP and CPT-11½ inhibitory concentrations (IC50 s) and decreased the ABCC1mRNA and protein expression.
Side-Effects of Irinotecan (CPT-11), the Clinically Used Drug for Colon Cancer Therapy, Are Eliminated in Experimental Animals Treated with Latex Proteins from Calotropis procera (Apocynaceae).
Taken together, combination of PLK1-specific shRNA interference with low-dose CPT-11 triggered a antitumor efficacy and represented a potential strategy to treat colon cancer.
The irinotecan-resistant (CPT-11-R) LoVo colon cancer cell line was previously constructed by stepwise CPT-11 challenges to untreated parental LoVo cells.
The present study established a CPT‑11-resistant colon cancer cell line, LoVo/CPT‑11 cells, and detected the expression levels of CSC identification markers [cluster of differentiation (CD)44, CD133, epithelial cell adhesion molecule (EpCAM) and CD24] in parental cells and CPT‑11-resistant cells.
The results showed that CPT-11 is an effective inhibitor of angiogenesis and provided strong implications for wider clinical application of CPT-11 for colon cancer.
These data demonstrate that the protection from apoptosis induced in response to CPT-11 treatment is effectively inhibited by the transient inhibition of NF-kappaB in a variety of human colon cancer cell lines and in a tumor xenograft model, resulting in a significantly enhanced tumoricidal response to CPT-11 via increased induction of apoptosis.
