Embodiment

[0034] 1. Materials and methods

[0035] 1.1 Study Approval

[0036] All animal experiments were performed with institutional approval from the Yale University Animal Care Committee. Human tumor spheroids from patients with advanced (ie, stage III-IV) ovarian cancer were collected from ascitic fluid provided by informed consenting patients as completed at Yale University School of Medicine, New Haven, CT (HIC protocol #1111003959). Clinical paraffin specimens were used after approval by the Ethics Review Committee of Cancer Hospital Affiliated to Harbin Medical University, China.

[0037] 1.2 Animal models

[0038] All animal experiments were performed with the approval of the Yale University Animal Care Committee. All mice were of the C57BL / 6 series. Lysozyme Cre mice were crossed with tomato (mT / mG) mice to extract cells with the lineage marker lysozyme. Nude mice were purchased from Jackson Laboratory. Cell culture medium was grown on 100 μl mouse ovarian cancer...

Abstract

The invention discloses an application of ICAM-1 or alphaMbeta2 integral protein in screening of medicine for diagnosing or treating implantation metastatic cancer. The application firstly verifies that the ICAM-1 or alphaMbeta2 integral protein plays an important regulating effect in the ovarian cancer implantation metastasis process on a mice in-situ ovarian cancer model and discloses the formation basis mechanism of the ovarian cancer sphere, and can provide theoretical foundation for the screening of the medicine for diagnosing or treating implantation metastatic cancer.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and particularly relates to the use of ICAM-1 or αMβ2 integrin in screening medicines for diagnosing or treating implanted metastatic cancer. Background technique [0002] Ovarian cancer (OC) is the second most common cancer and one of the leading causes of death in gynecology in the United States. The high mortality rate is mainly due to the difficulty of diagnosing ovarian cancer in the early stage (I / II) until it spreads to the advanced stage (III / IV). We have reported that the confirmed rates from stage I to IV in OC patients were 7.19%, 8.63%, 72%, and 72.18%, respectively. The prognosis of OC patients is poor, and the five-year average survival rate of OC patients in all stages is 42%. Long-term follow-up of patients with stages III and IV found that the five-year survival rate was less than 10%; however, for patients with early (I-II) diagnosis, especially those whose tumors were con...
