摘要: The invention discloses a tamoxifen drug resistance related microRNA molecule MiR-200a and application thereof, belongs to the field of tumor biotherapy. nucleotide sequence disclosed by is as shown in SEQ ID NO. 1. MiR-200a, novel breast cancer drug-resistance marker, has characteristics low expression ER positive cells high sensitive cells. Therefore, provides new target for designing drugs, subsequently, directly corresponding resistance, are designed developed. biological function an action mechanism promoting cell resistance; therefore, effective way provided reversal improvement clinical chemotherapeutic effect on cancer.
