Inhibition of cell aggregation by specific carbohydrates

Role of Phosphoramidate Antisense in Specific Inhibition of K562 Leukemic Cell Line

Isolation by cell-column chromatography of immunoglobulins specific for cell surface carbohydrates

A new method of affinity chromatography using glutaraldehyde-fixed cells immobilized on Sephadex beads has been used to isolate immunoglobulins (Ig's) specific for cell surface glycoproteins. Ig's that specifically bound and agglutinated the same cells as those originally fixed on the columns were isolated from nonimmune sera of various species. Periodate treatment of the cell-columns and the f...

Specific Inhibition of the Expression of the Promyelocytic Leukemia (PML) Protein by Anti-Sense Oligonucleotides

In the present study, using anti-sense oligonucleotides the inhibition of expression of the PML protein hasbeen investigated. The anti-sense oligonucleotides were designed against the translation initiation site ofthe PML gene, and their effects were investigated on cellular growth and DNA synthesis. Incubation of normalhuman fibroblast cells with the anti-sense oligonucleotid...

Expression of CK8 and CK17, Specific Epithelial Markers, by Oral Squamous Cell Carcinoma Cell Lines

Objectives Oral squamous cell carcinoma (OSCC) is among the most common cancers worldwide. This study aimed to assess the expression of CK8 and CK17 by OSCC cell lines in Iranian patients. Methods This observational study was conducted on three OSCC cell lines with a minimum of 45 passages. Cells isolated from three patients with OSCC were cultured and passaged. Expression of CK8 and CK17 epi...

Inhibition of in vivo tumor growth by a monoclonal IgM antibody recognizing tumor cell surface carbohydrates.

We have shown previously that IgM from Ehrlich tumor (ET)-immunized mice, recognizing ET cell surface carbohydrates, protects control mice to a subsequent tumor challenge. The factors involved in such IgM-mediated protection were unknown, since it was independent of complement activation. Here, we have extended these in vivo studies by means of monoclonal IgM antibodies. Two of them (A10 and E1...
