Therapeutic Strategies Targeting SLC6A6 to Enhance Cisplatin Sensitivity in Ovarian Cancer

The solute carrier family 6 member 6 (SLC6A6) is a taurine transporter that has been implicated in the resistance of ovarian cancer cells to cisplatin, a common chemotherapeutic agent. Recent studies have shown that targeting SLC6A6 can sensitize ovarian cancer precursor cells to cisplatin treatment.

1. Mechanism of SLC6A6 in Cisplatin Resistance

Research indicates that SLC6A6 expression is associated with increased survival of ovarian cancer cells under cisplatin treatment. Specifically, the expression of mutant p53, commonly found in ovarian cancer, enhances the protective role of SLC6A6 against cisplatin-induced DNA damage. Depletion of SLC6A6 using shRNA has been shown to increase cisplatin sensitivity in fallopian tube non-ciliated epithelial (FNE) cells expressing mutant p53R175H, suggesting that SLC6A6 contributes to the resistance mechanism in these cells.

2. Therapeutic Strategies

shRNA-Mediated Depletion: Utilizing lentiviral delivery of small hairpin RNA (shRNA) to specifically target and reduce SLC6A6 expression has been demonstrated to resensitize FNE cells to cisplatin. This approach effectively disrupts the protective mechanism conferred by SLC6A6, leading to increased cell death upon cisplatin treatment.
Taurine Supplementation: Since SLC6A6 is responsible for taurine transport, manipulating taurine levels in the tumor microenvironment could influence cisplatin sensitivity. Studies suggest that taurine may have protective effects against DNA damage, thus its modulation could be a double-edged sword in therapy.
Combination Therapies: Combining cisplatin with other agents that inhibit SLC6A6 or enhance its degradation could synergistically improve treatment outcomes. For instance, using agents that disrupt the p53-SLC6A6 interaction may further enhance cisplatin efficacy.

3. Clinical Implications

Targeting SLC6A6 presents a promising strategy to overcome cisplatin resistance in ovarian cancer. The findings from recent studies highlight the potential of SLC6A6 as a therapeutic target, suggesting that its inhibition could lead to improved responses to cisplatin in patients with ovarian cancer.

4. Future Directions

Further research is needed to explore the full range of SLC6A6's roles in ovarian cancer and to develop targeted therapies that can effectively inhibit its function. Clinical trials assessing the efficacy of SLC6A6-targeting strategies in combination with cisplatin are warranted.
