Ovarian cancer is a gynecological malignant tumor with the highest mortality rate, and chemotherapy resistance seriously affects patient therapeutic outcomes. It has been shown that the high expression of anti‑apoptotic proteins Bcl‑2 and Bcl‑xL is closely related to ovarian cancer chemotherapy resistance. Therefore, reducing Bcl‑2 and Bcl‑xL expression levels may be essential for reversing drug resistance in ovarian cancer. ABT‑737 is a BH3‑only protein mimetic, which can effectively inhibit the expression of the anti‑apoptotic proteins Bcl‑xL and Bcl‑2. Although it has been shown that ABT‑737 can increase the sensitivity of ovarian cancer cells to cisplatin, the specific molecular mechanism remains unclear and requires further investigation. In the present study, the results revealed that ABT‑737 can significantly increase the activation levels of JNK and ASK1 induced by cisplatin in A2780/DDP cells, which are cisplatin‑resistant ovarian cancer cells. Inhibition of the JNK and ASK1 pathway could significantly reduce cisplatin cytotoxicity increased by ABT‑737 in A2780/DDP cells, while inhibiting the ASK1 pathway could reduce JNK activation. In addition, it was further determined that ABT‑737 could increase reactive oxygen species (ROS) levels in A2780/DDP cells induced by cisplatin. Furthermore, the inhibition of ROS could significantly reduce JNK and ASK1 activation and ABT‑737‑mediated increased cisplatin cytotoxicity in A2780/DDP cells. Overall, the current data identified that activation of the ROS‑ASK1‑JNK signaling axis plays an essential role in the ability of ABT‑737 to increase cisplatin sensitivity in A2780/DDP cells. Therefore, upregulation the ROS‑ASK1‑JNK signaling axis is a potentially novel molecular mechanism by which ABT‑737 can enhance cisplatin sensitivity of ovarian cancer cells. In addition, the present research can also provide new therapeutic strategies and new therapeutic targets for patients with cisplatin‑resistant ovarian cancer with high Bcl‑2/Bcl‑xL expression patterns.

Ferroptosis inducers (FIN) have a key role in cancer therapy and provide novel and innovative treatment strategies. Although many researchers have performed FIN screening of synthetic compounds, studies on the identification of FIN from natural products are limited, particularly in the field of drug development and combination therapy. In this review, this gap was addressed by comprehensively summarizing recent studies on ferroptosis. The causes of ferroptosis were categorized into driving and defensive factors, elucidating key pathways and targets. Next, through summarizing research on natural products that induce ferroptosis, the study elaborated in detail on the natural products that have FIN functions. Their discovery and development were also described and insight for clinical drug development was provided. In addition, the mechanisms of action were analyzed and potential combination therapies, resistance reversal and structural enhancements were presented. By highlighting the potential of natural products in inducing ferroptosis for cancer treatment, this review may serve as a reference for utilizing these compounds against cancer. It not only showed the significance of natural products but may also promote further investigation into their therapeutic effects, thus encouraging research in this field.
铁色素沉着诱导剂(FIN)在癌症治疗中发挥着关键作用,并提供了新颖、创新的治疗策略。尽管许多研究人员已经对合成化合物进行了FIN筛选,但从天然产物中鉴定FIN的研究还很有限,尤其是在药物开发和联合治疗领域。在这篇综述中,通过全面总结近期有关铁中毒的研究,填补了这一空白。研究人员将铁中毒的原因分为驱动因素和防御因素,阐明了关键途径和靶点。接下来,研究通过总结有关诱导铁变态反应的天然产物的研究,详细阐述了具有 FIN 功能的天然产物。研究还介绍了它们的发现和发展,并为临床药物开发提供了启示。此外,还分析了其作用机制,并介绍了潜在的联合疗法、抗药性逆转和结构增强。这篇综述强调了天然产物在诱导铁蛋白沉积治疗癌症方面的潜力,可作为利用这些化合物抗癌的参考。它不仅显示了天然产物的重要意义,还可能促进对其治疗效果的进一步研究,从而鼓励这一领域的研究。

The mitochondria‑associated endoplasmic reticulum (ER) membrane (MAM), serving as a vital link between the mitochondria and ER, holds a pivotal role in maintaining the physiological function of these two organelles. Its specific functions encompass the participation in the biosynthesis and functional regulation of the mitochondria, calcium ion transport, lipid metabolism, oxidative stress and autophagy among numerous other facets. Scientific exploration has revealed that MAMs hold potential as effective therapeutic targets influencing the mitochondria and ER within the context of cancer therapy. The present review focused on elucidating the related pathways of mitochondrial autophagy and ER stress and their practical application in ovarian cancer, aiming to identify commonalities existing between MAMs and these pathways, thereby extending to related applications of MAMs in ovarian cancer treatment. This endeavor aimed at exploring new potential for MAMs in clinically managing ovarian cancer.

In years of research on classical pathways, the composition, information transmission mechanism, crosstalk with other pathways, and physiological and pathological effects of hedgehog (HH) pathway have been gradually clarified. HH also plays a critical role in tumor formation and development. According to the update of interpretation of tumor phenotypes, the latest relevant studies have been sorted out, to explore the specific mechanism of HH pathway in regulating different tumor phenotypes through gene mutation and signal regulation. The drugs and natural ingredients involved in regulating HH pathway were also reviewed; five approved drugs and drugs under research exert efficacy by blocking HH pathway, and at least 22 natural components have potential to treat tumors by HH pathway. Nevertheless, there is a deficiency of existing studies. The present review confirmed the great potential of HH pathway in future cancer treatment with factual basis.

Intrahepatic cholangiocarcinoma (ICC) is a type of liver cancer associated with poor prognosis and increased mortality; the limited treatment strategy highlights the urgent need for investigation. Traditional Chinese Medicine (TCM), used alone or in combination with other treatments, can enhance therapeutic efficacy, improve life quality of patients and extend overall survival. In total, two rounds of screening of a TCM library of 2,538 active compounds were conducted using a Cell Counting Kit‑8 assay and ICC cell lines. Cell proliferation and migration abilities were assessed through colony formation, 5‑ethynyl‑2'‑deoxyuridine, would healing and Transwell assays. The impact of digitoxin (DT) on signaling pathways was initially investigated using RNA sequencing and further validated using reverse transcription‑quantitative PCR, western blotting, lectin blotting and flow cytometry. ICC cells stably overexpressing ST6 β‑galactoside α‑2,6‑sialyltransferase 1 (ST6GAL1) were generated through lentiviral transfection. It was shown that DT emerged as a highly effective anti‑ICC candidate from two rounds high‑throughput library screening. DT could inhibit the proliferation and migration of ICC cells by suppressing NF‑κB activation and reducing nuclear phosphorylated‑NF‑κB levels, along with diminishing ST6GAL1 mRNA and protein expression. The aforementioned biological effects and signal pathways of DT could be counteracted by overexpressing ST6GAL1 in ICC cells. In conclusion, DT suppressed ICC cell proliferation and migration by targeting the NF‑κB/ST6GAL1 signaling axis. The findings of the present study indicated the promising therapeutic effects of DT in managing ICC, offering new avenues for treatment strategies.

Radiotherapy exhibits significant versatility and efficacy in cancer treatment, thereby playing a crucial role in the field of oncology. However, there remains an urgent need for extensive research on various aspects of radiotherapy, including target selection, damage repair and its combination with immunotherapy. Particularly, the development of in vitro models to replicate in vivo tumor lesion responses is vital. The present study provides a thorough review of the establishment and application of tumor organoids in radiotherapy, aiming to explore their potential impact on cancer treatment.
