Studies on concanavalin A receptor sites of tumour cells following ultraviolet exposure

Oncology. 1984;41(1):61-3. doi: 10.1159/000225792.

Abstract

Alteration of surface receptor of Ehrlich tumour cells by concanavalin A (Con A), shortwave UV and UV plus Con A have been studied. DNA of nuclear chromatins is highly sensitive to UV but receptor glycoprotein sites are UV resistant as evidenced by their retention of agglutination properties after radiation. Con A and UV plus Con A treatments of tumour cells delay the in vivo growth of solid tumour which may be due to some immunological mechanism.
