The negative regulation of FOXP4‑AS1 on miR‑423‑5p compared to that of miR‑423‑5p on NACC1 was determined at the mRNA or protein levels in MCL cells. Moreover, an inverse expression correlation between FOXP4‑AS1 and miR‑423‑5p, and that between miR‑423‑5p and NACC1 was confirmed in MCL clinical samples. In addition, rescue assay showed that miR‑423‑5p upregulation or NACC1 knockdown abolished the promoting effects of FOXP4‑AS1 on MCL cell proliferation, migration and invasion. In conclusion, FOXP4‑AS1 promotes MCL progression through the upregulation of NACC1 expression by inhibiting miR‑423‑5p. FOXP4‑AS1 may serve as a novel therapeutic target for patients with MCL.Ovarian cancer is a gynecological malignancy with high mortality. Adjuvant therapy such as chemoradiotherapy inevitably leads to side effects and drug resistance. In recent years, traditional Chinese medicine has been widely studied for its safety, effectiveness, and unique pharmacological effects. Polyphyllin VII is an important component of Rhizoma paridis saponins, and has cytotoxic effects on many types of cancer cells. The aim of the present study was to evaluate the anti‑tumor activity of polyphyllin VII in human ovarian cancer cells. Recent studies found that polyphyllin VII induces mitochondrial pathway apoptosis by increasing mitochondrial division, but the specific mechanism was unclear. The results of this study revealed that polyphyllin VII could effectively induce mitochondrial dysfunction, including increased mitochondrial division and reactive oxygen species (ROS) production. Notably, the mitochondrial location of dynamin‑related protein 1 (DRP1) plays an important role in its function. In addition, polyphyllin VII enhanced the mitochondrial localization of DRP1 whi
