Abstract

The invention discloses application of human ribosomal protein L23 label peptide to preparation of anti-cancer medicines. The amino acid sequence of the human ribosomal protein L23 label peptide is defined by SEQ ID NO:1. The human ribosomal protein L23 label peptide has time and dose dependence on growth inhibition rate of human breast cancer Bcap-37. The human ribosomal protein L23 label peptide at the concentrations of 0.2, 0.5 and 0.8 ug / ml has a good effect on growth inhibition of the human breast cancer Bcap-37, wherein the growth inhibition ratio of the human ribosomal protein L23 label peptide at the concentration of 0.5 ug / ml on the human breast cancer Bcap-37 is highest and reaches 72.29 percent.

Description

technical field [0001] The invention relates to the application of human ribosomal protein L23 tag polypeptide in the preparation of anticancer drugs, and belongs to the technical field of biomedicine. Background technique [0002] Ribosomes are organelles that catalyze protein synthesis. Mammalian ribosomes are composed of 4 RNAs and about 80 different proteins. The names of ribosomal proteins are related to the size of the protein in the ribosome. The small subunit ribosomal proteins are named S1 to S31, and the large subunit The base ribosomal proteins are named L1 to L44. The RPL23a protein is a component of the 60S ribosomal protein. The ribosomal protein encoded by the RPL23A gene is a component of the 60S subunit. This protein belongs to the L23P family of ribosomal proteins. It exists in the cytoplasm. In recent years, some research results have shown that the RPL23A gene is involved in cell growth and regulation. The cDNA and structural gene of the human ribos...
