Efficacy of ABCA1 Transporter Proteins in Patients with Endometrial Cancer: an In Vitro Study

Endometrial carcinoma (EC) is a typical gynecological malignant tumor that occurs more frequently every year. Obesity is a significant contributor to the development of EC and its prognosis. Lipid metabolism and malignant tumors have a long history of association. Elevated cholesterol levels are made possible by adenosine triphosphate-binding cassette protein A1 (ABCA1) deficiency, which eventually promotes cancer cell survival. The aim of this study was to examine at the ABCA1 gene expression levels in EC patients. The relationship between ABCA1 and the occurrence, progression, and prognosis of EC is discussed in this article as a potential mechanism.

The samples of 45 endometrial adenocarcinoma patients were retrospectively included in this study and they were further divided into Grade 1 (15), Grade 2 (15), Grade 3 (15) tumors, control group. Twenty-nine endometrial tissues without a confirmed diagnosis of endometrial cancer made up the control group. ABCA1 gene expression was examined using real-time polymerase chain reaction.

According to the results, the gene expressions of the patient group were higher than the control group When each Grade was compared with the control group, statistically significant results were obtained. After analyzing the data, it was found that the patient group was generally higher than the control group (p < 0.05) and there were differences in the grades of the patient group (p < 0.05). When the ABCA1 expressions of the grade groups and control groups were compared separately, a difference was found between Grade 1, Grade 2 and Grade 3 and the control group (p= 0.0001).

According to the findings of our study, a key component in the growth of EC tumors is the increase in cholesterol production caused by a reduction in ABCA1.
