Abstract

Background

Paclitaxel, a tubulin-binding agent, is a Food and Drug Administration-approved first-line drug for the treatment of non-small cell lung cancer (NSCLC), for both squamous and non-squamous cell lung carcinoma, with paclitaxel/carboplatin + bevacizumab a common chemotherapy regimen for stage IV non-squamous NSCLC; however, primary or acquired resistance to paclitaxel is gradually increasing, leading to treatment failure.

Methods

Our results show that Ras-related C3 botulinum toxin substrate 3 (RAC3) is overexpressed in cultured paclitaxel-resistant cells and that RAC3 expression levels are negatively correlated with sensitivity of lung adenocarcinoma cells to paclitaxel. Pulsatilla saponin D could inhibit RAC3 expression, and we hypothesize that it may block paclitaxel resistance. Further, we found that treatment with paclitaxel combined with Pulsatilla saponin D, can overcome lung adenocarcinoma cell resistance to paclitaxel alone in cell culture and mouse xenograft models.

Keynote webinar | Spotlight on antibody–drug conjugates in cancer

Antibody–drug conjugates (ADCs) are novel agents that have shown promise across multiple tumor types. Explore the current landscape of ADCs in breast and lung cancer with our experts, and gain insights into the mechanism of action, key clinical trials data, existing challenges, and future directions.
