In this study, we developed a cationic liposome-based nanoparticle loaded with miR-139-5p (miR-139-5p-HSPC/DOTAP/Chol/DSPE-PEG2000-COOH nanoparticles, MNPs) and surface-decorated with epithelial cell adhesion molecule (EpCAM) aptamer (Apt) (miR-139-5p-EpCAM Apt-HSPC/DOTAP/Chol/DSPE-PEG2000-COOH nanoparticles, MANPs) for the targeted treatment of CRC.
Six formalin-fixed paraffin-embedded CRCs developed within SSA/P were profiled for the immunohistochemical expression of MMR proteins (MLH1, MSH2, MSH6, PMS2, and Ep-CAM), p16, and β-catenin.
STn<sup>+</sup> CTC counts were significantly higher than EpCAM-based detection in colorectal cancer, providing a more efficient cell-surface biomarker for CTC isolation.
Adjuvant Chemotherapy With or Without Biologics Including Antiangiogenics and Monoclonal Antibodies Targeting EGFR and EpCAM in Colorectal Cancer: A Systematic Review and Meta-analysis.
Here, we developed a DNase I enzyme-aided fluorescence amplification method for CRC exosome detection, based on graphene oxide (GO)-DNA aptamer (CD63 and EpCAM aptamers) interactions.
We aim to explore the regulatory mechanism of miR-328 and further develop miR-328-loaded mesoporous silica nanoparticles (MSNs) and surface-decorated with polymerized dopamine, epithelial cell adhesion molecule aptamer and bevacizumab for the dual-targeting treatment of colorectal cancer (CRC).
Most importantly, Lgr5+CD44+EpCAM+ cells exhibited more pronounced CSC-like traits than did any other subpopulation, indicating that Lgr5 combined with CD44 and EpCAM can further improve the stem-like traits of CSCs in colorectal cancer.
Our results suggest that GA733-2-Fc conjugated to ER-retention motif KDEL is a more efficient antigen to prevent tumor growth induced by colorectal carcinoma and minimize an allergic response.
Ep-CAM expression was significantly higher in CRC compared with normal controls, and its overexpression was negatively linked to tumor differentiation, tumor stage, vascular invasion, depth of tumor invasion, lymph node metastasis, distant metastasis, and tumor budding in CRC patients.
In this study, we identified CTCs using the previously reported CanPatrol CTC enrichment technique from peripheral blood samples of 126 patients with colorectal cancer (CRC) and found that CTCs could be classified into three subpopulations based on expression of epithelial cell adhesion molecule (EpCAM) (E-CTCs), the mesenchymal cell marker vimentin (M-CTCs), or both EpCAM and vimentin (biphenotypic E/M-CTCs).
EPCAM-CL can be used to screen for EPCAM deletion-induced Lynch syndrome-associated CRC, whereas EPCAM-PL can be used as an indicator of tumor aggressiveness and poor prognosis in CRC.
In conclusion, this study for the first time indicates that expression of EpCAM(MT) is associated with a more aggressive phenotype and predicts poor survival in patients with colorectal cancer.
Previously we reported that LIM1863 colorectal cancer (CRC) cells secrete three distinct extracellular vesicle subtypes - two subpopulations of exosomes (apical EpCAM-Exos and basolateral A33-Exos) and shed microvesicles (sMVs) - with distinct protein and miRNA signatures.
Approximately 12-17 % of CRCs demonstrate MSI with germline mutations in genes involved in DNA mismatch repair, MLH1, MSH2, MSH6, PMS2 and TACSTD1/EPCAM and somatic MLH1 promotor hypermethylation being alternative pathways for the development of microsatellite unstable CRC.
This included quality control, consisting of the confirmation of human and colorectal cancer (CRC) origin by DNA fingerprint and epithelial cell adhesion molecule (EpCAM) staining, as well as mycoplasma and human virus testing.
GA733-1 gene expression was significantly higher in cancerous samples; conversely, the GA733-2 mRNA levels were higher in noncancerous tissues, and were significantly correlated with lymph node perforation in colorectal cancer (P < 0.05).
Using data from the Colon Cancer Family Registry, we compared the proportion of childhood cancers (diagnosed before 18 years of age) in the first-, second-, and third-degree relatives of 781 probands with a pathogenic mutation in one of the MMR genes; MLH1 (n = 275), MSH2 (n = 342), MSH6 (n = 99), or PMS2 (n = 55) or in EPCAM (n = 10) (Lynch syndrome families), with that of 5073 probands with MMR-deficient colorectal cancer (non-Lynch syndrome families).
Finally, we found that patients with LLS and LS-EPCAM shared clinical features that differed from LS-MMR patients, including lower frequency of fulfillment of the revised Bethesda guidelines (83.6 and 86.7% vs. 98.1% for LS-MMR) and older mean age at CRC diagnosis (52.6 and 52.7 years vs. 43.9 years for LS-MMR).
