[0040] 1 Materials and methods

[0041] 1.1 Data mining in Oncomine. Gene copy number and expression data for patients and cell lines were extracted from the Oncomine database (www.oncomine.org). TACR1 copy number level data were obtained from Reporter 02-072503625 of the Barretina CellLine 2 (GSE36138) dataset. TACR1 mRNA expression levels were obtained from Reporter 208048_at of the GarnettCellLine dataset. TAC1 copy number level data were obtained from Reporter07-097203463 of the Barretina CellLine2 (GSE36138) dataset. TAC1 mRNA expression levels were obtained from Reporter206552_s_at of the GarnettCellLine dataset.

[0042] 1.2 Cell culture. In the research of the present invention, HCT116 and SW620 cells were obtained from the First Affiliated Hospital of Zhejiang University, and HCT116 cells (HCT116 / 5-FU) resistant to 5-FU were obtained from Beijing Beina Chuanglian Biotechnology Research Institute. SW620 was cultured in DMEM (Life Technologies), and HCT116, HCT116 / ...

Abstract

The present invention relates to the role of neurokinin 1 receptor antagonists in promoting chemosensitivity and reversing chemoresistance in colorectal cancer. Specifically, the present invention relates to a method of promoting cancer chemotherapy sensitivity in a subject or reversing cancer chemotherapy resistance in a subject, comprising administering a therapeutically effective amount of an NK-1R antagonist to the subject. Furthermore, the present invention relates to a pharmaceutical composition for treating colorectal cancer, which comprises NK‑1R antagonist, chemotherapy drugs, and optional pharmaceutically acceptable carriers.

Description

technical field [0001] The invention belongs to the field of medicine, in particular to a method for promoting chemosensitivity and reversing chemoresistance in the treatment of colorectal cancer, and a pharmaceutical product containing a neurokinin 1 receptor antagonist. Background technique [0002] Colorectal cancer (CRC) is the second and third most common cancer diagnosed in women and men, respectively, and mortality is increasing [1] . Since 1995, the incidence, especially among young adults under the age of 50, has increased by 2.2% per year [2] . Using current standard treatments, including surgery, chemotherapy, and radiation, the 5-year relative survival rate for CRC patients is 65%, however, this rate drops to 12% for CRC patients with stage IV disease [3] . Therefore, understanding the pathogenesis of CRC and developing new therapies represent an unmet clinical need for CRC patients. [0003] Substance P (Substance P, SP) is the first member of the tachykini...
