HOTAIR level increased in the PBMCs and tumor tissues from the breast cancer patients. A): PBMCs were collected from 20 patients with breast cancer and 20 healthy women. Then the expression of HOTAIR was detected using real-time PCR. B): Fresh 20 human breast cancer tissues and 20 normal human breast tissues were collected and HOTAIR expression was assessed with real-time PCR. C): PBMCs were collected from 10 patients with breast cancer migration and 10 without migration. Then the expression of HOTAIR was detected using real-time PCR. D): Fresh 10 breast cancer tissues from patients with breast cancer migration and 10 without migration were collected and HOTAIR expression was assessed by using real-time PCR. *p < 0.05, **p < 0.01.
