Abstract:Abstract. The substance P (SP; also known as TAC1)/neurokinin-1 receptor (NK1R; also known as TACR1) complex is a critical part in the development of cancer. Therefore, NK1R antagonists, such as the clinical drug aprepitant, are currently under investigation as future anticancer agents. In a previous study, NK1R (TACR1) was identified as a potent anticancer target in hepatoblastoma (HB). However, little is known regarding the exact distribution of this target among HB subsets and whether it correlates with cli… Show more
“…However, gene expression levels were independent from clinical markers like INSS stage, MYCN status, histology, and outcome. These results are in accordance with results we have previously published for hepatoblastoma (42).…”

“…Therefore, our group recently performed an in-depth analysis of the expression pattern of NK1R in hepatoblastoma and correlated these findings with clinical data on tumor stage, biology and outcome of 47 children with hepatoblastoma treated in Germany (155).…”

“…This correlation at the protein level has been previously detected in different cancer types. Thus, in colitis-associated colon cancer, in hepatoblastoma, and in breast cancer primary tumors, NK1R-Tr levels increase progressively with cancer progression (18,19,47). In addition, breast cancer cell lines showed…”
These and our previous data demonstrate that the whole tachykinin system is differentially regulated in leiomyomas. The increased expression of NK1R-Tr might stimulate leiomyoma growth in a similar way to that observed in other steroid-dependent tumors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
