Cisplatin resistance is a main clinical problem of lung cancer therapy. Gambogic acid (GA) could prohibit the proliferation of a variety of human cancer cells. However, the effects of GA on cisplatin-resistant lung cancer are still unclear. The objective of the present study was to find out the antitumor effects of GA on cisplatin-resistant human lung cancer A549/DDP cells and further explore i...

Lung cancer is currently the leading cause of cancer-related mortality worldwide. In Taiwan, lung cancer is also the type of malignancy that is the major cause of cancer-mortality. Investigating the mechanism of apoptosis of lung cancer cells is important in the treatment of lung cancer. In the present study, isolinderalactone was demonstrated to exhibit anticancer effects in A549 human non-sma...

Gemcitabine is one of the most widely used chemotherapy drugs for advanced malignant tumors, including non‑small cell lung cancer. However, clinical efficacy gemcitabine limited due to drug resistance. The aim present study was investigate role p21 in gemcitabine‑resistant A549 (A549/G+) cancer cells. IC50 values were determined using a Cell Counting Kit‑8 (CCK‑8) assay. m...

Objective(s): Combination chemotherapy is a rational strategy to increase patient response and tolerability and to decrease adverse effects and drug resistance. Recently, the use of non-steroidal anti-inflammatory drugs (NSAIDs) has been reported to be associated with reduction in occurrence of a variety of cancers including lung cancer. On the other hand, growing evidences suggest that deuteri...

Background: Ficus auriculata (fig) has immense value of benefits with regards to their medicinal and therapeutic properties. It has been long used in traditional folk medicine, and one of the fruits mentioned in Al-Quran. Many scientific researches have proven the usage of this natural medicine in in vitro and in vivo studies, where anti-cancer is among of its recognized properties. Objective...

irradiation and is a widely accepted therapeutic method for treating various types of cancers. However, a portion of cancer cells survives even after radiotherapy and leads to the development of recurrent tumors that gives rise to more malignant phenotypes than that before irradiation. We previously reported that any lung cancer cells that survive after irradiation have high invasiveness, which...

Several genome-wide association studies (GWASs), have identified that FAM13A and IREB2 loci are associated with lung cancer, but the mechanisms by which these genes contribute to lung diseases susceptibility, especially in hypoxia context, are unknown. Hypoxia has been identified as a major negative factor for tumor progression in clinical observation. It has been suggested, that lower oxygen t...

The development of chemoresistance to cisplatin regimens causes a poor prognosis in patients with advanced NSCLC. The role of noncanonical Wnt signaling in the regulation of properties of lung cancer stem cells and chemoresistance was interrogated, by accessing capacities of cell proliferation, migration, invasion, and clonogenicity as well as the apoptosis in A549 cell lines and cisplatin-resi...

Tripchlorolide (T4) has been shown to induce A549 lung cancer cell death predominantly by activating an autophagy pathway. However, the underlying mechanism remains unclear. Herein, we demonstrated that compared with T4 treatment alone, pretreatment with wortmannin (an inhibitor of phosphatidylinositol 3-kinase), perifosine (an inhibitor of AKT) or rapamycin (an inhibitor of mTOR) combined with...

Background and purpose: Cancer is one of the major health challenges in the world. The efficacy of current treatments is low but their side effects are high. Cold atmospheric plasma (CAP) is a new modality for cancer treatment. This study aimed to compare the cytotoxicity effect of CAP on the cell line models of common cancers and normal cells. Materials and methods: In this experimental study...
