LAMC3 interference reduces drug resistance of carboplatin-resistant ovarian cancer cells
Abstract Ovarian cancer is the most lethal tumor in female reproductive system, which seriously threatens the life and health of women. Our previous study found that LAMC3 was down-regulated in ovarian cancer tissues and correlated with ovarian cancer resistance. However, the effects of LAMC3 interf...

| Summary: | Abstract Ovarian cancer is the most lethal tumor in female reproductive system, which seriously threatens the life and health of women. Our previous study found that LAMC3 was down-regulated in ovarian cancer tissues and correlated with ovarian cancer resistance. However, the effects of LAMC3 interference on drug resistance in carboplatin-resistant ovarian cancer cells remain unknown. In the present study, the effects of LAMC3 interference on drug resistance, cell proliferation, cycle, apoptosis, and ultrastructure of carboplatin-resistant ovarian cancer cells were examined. The results showed that LAMC3 interference lowered drug resistance of carboplatin-resistant ovarian cancer cells. The cell proliferation was inhibited and cell apoptosis was promoted in carboplatin-resistant ovarian cancer cells with LAMC3 interference. Besides, LAMC3 interference arrested cell cycle and affected cell ultrastructure of carboplatin-resistant ovarian cancer cells. Furthermore, transcriptome sequencing and WB verification results revealed cell cycle, autophagy, ferroptosis, lysosome related key pathway proteins may be involved in LAMC3 interference regulating drug resistance of carboplatin-resistant ovarian cancer cells. This study indicated LAMC3 interference reduced drug resistance of carboplatin-resistant ovarian cancer cells principal by affecting cell cycle, autophagy, ferroptosis, and lysosome. The present study provides a potential target for clinical treatment of drug resistance in ovarian cancer. |
