Abstract

Background:  Drug resistance is a major challenge for the treatment of high-grade serous ovarian carcinoma (HGSOC), frequently leading to disease recurrence and therapeutic failure.

Objective: This study investigated the cellular phenotypic and molecular bases of drug resistance in human ovarian cancer cell line such as OVCAR4.

Method: The chlorpromazine (CPZ) and metformin repurposed drugs were used for the treatment of ovarian cancer cells to follow the treatment response, and the hemocytometer and clonogenic assay were used, followed by the ANOVA and Tukey’s HSD post hoc test for statistical analysis. Surviving cell populations were recognized as drug resistant and further analysed at the molecular level. The OVCAR4 cells were used for RNA isolation and then converted into cDNA and used for real-time PCR, and PCR amplicons were verified by gel electrophoresis

Results: The molecular results were linked to the observable outcomes from the hemocytometer and clonogenic assay after drug treatment.

Conclusion: The research study provides a drug resistance-related inclusive analysis in ovarian cancer. Cellular and molecular analyses provide in vitro identification of resistance-associated markers and open a future path for therapeutic approaches to overcome drug resistance in ovarian cancer.
