Mammary tumors induce select cognitive impairments
چکیده انگلیسی
Cancer, in addition to many other chronic diseases, is associated with serious and problematic behavioral symptoms, including cognitive impairments. In humans, various factors likely contribute to cancer-associated cognitive deficits including disease awareness and chemotherapy; however, the endogenous biological factors arising from tumor development may also play a causal role. In the present study, rats with mammary tumors exhibited impaired spatial reference memory on a radial arm maze and amnesia for familiar objects in an object recognition memory test. In contrast, their performance in the Morris water maze and in fear conditioning tests was comparable to that of controls. These select cognitive impairments were accompanied by elevations in hippocampal interleukin-1β mRNA expression, but were not associated with decreases in hippocampal brain-derived neurotrophic factor gene expression. Together the results indicate that peripheral tumors alone are sufficient to induce increases in hippocampal cytokine expression and select deficits in hippocampal-dependent memory tasks.
