We studied regulation of hypoxanthine transport depending on its concentration in the culture medium. Caco-2 cells were differentiated on membrane filters to create a model of the intestine. Different hypoxanthine uptake on the apical and basolateral cell membranes was observed. The expression of SLC29 family genes encoding passive nucleoside transporters increased upon changes in hypoxanthine concentration in the medium Localization of the transporters and their influence on the effect of pharmacological preparations are discussed.
