Chenopodium album L. is a common edible herb distributed in China that has been used as a traditional Chinese medicine for antiviral, antifungal, anti-inflammatory and cancer treatment. However, to the best of our knowledge no previous reports have investigated its the function of its phytochemical extracts in lung cancer cells. The purpose of the present study was to assess the anticancer acti...

Lung cancer remains the leading cause of cancer-related deaths worldwide, and non-small cell lung cancer (NSCLC) represents approximately 80% of total lung cancer cases. The use of non-toxic dietary phytochemicals can be considered as a chemotherapeutic strategy for the management of the NSCLC. Here, we report that grape seed proanthocyanidins (GSPs) induce apoptosis of NSCLC cells, A549 and H1...

Traditional or folk medicinal herbs continue to be prescribed in the treatment of various diseases and conditions in many cultures. Recent scientific efforts have focused on the potential roles of extracts of traditional herbs as alternative and complementary medications for cancer treatment. In Taiwan, Davallia divaricata Blume has been traditionally employed in folk medicine for therapy of lu...

Non-small-cell lung cancer (NSCLC) is one of the most leading causes of cancer-related deaths worldwide. Paclitaxel based combination therapies have long been used as a standard treatment in aggressive NSCLCs. But paclitaxel resistance has emerged as a major clinical problem in combating non-small-cell lung cancer and autophagy is one of the important mechanisms involved in this phenomenon. In ...

Lindera strychifolia, a scandent shrub Lauraceous medicinal plant, has been used in Chinese traditional medicine as a palliative and an anti-spasmodic. It also shows cytotoxic effects against several tumor cell lines and inhibits marcromolecule biosynthesis. This study investigated the anti-tumor effects of L. strychifolia extract against lung cancer cells using in vitro and in vivo models. Two...

We read with great interest the article in CHEST (July 2002) by Masakazu et al,1 who observed a haplotype loss of class I human leukocyte antigens (HLAs) in several newly established lung cancer cell lines and identified it as a mechanism of tumor escape from the immunosurveillance system of the host. However, as for the HLA genes of lung cancer cell lines passing for many generations, such as ...

Isorhamnetin (ISO) is a flavonoid from plants of the Polygonaceae family and is also an immediate metabolite of quercetin in mammals. To date, the anti‑tumor effects of ISO and the underlying mechanisms have not been elucidated in lung cancer cells. The present study investigated the inhibitory effects of ISO on the growth of human lung cancer A549 cells. Treatment of the lung cancer cells with...

Cancer is a major health problem and it has been causing great damage in recent years worldwide. Serious side effects of chemotherapeutics used cancer treatment make natural products valuable. Combined use chemotherapy drugs herbal an important approach reducing revealing more effective treatment. In this study, the methanolic extract from Portulaca oleracea (POM) alone combination with Irinote...

BACKGROUND Paris polyphylla (Chinese name: Chonglou) had been traditionally used for a long time and shown anti-cancer action. Based on the previous study that paris polyphylla steroidal saponins (PPSS) induced cytotoxic effect in human lung cancer A549 cells, this study was designed to further illustrate the mechanisms underlying. MATERIALS AND METHODS The mechanisms involved in PPSS-induced...

N,N-Dimethyl-D-erythro-sphingosine (DMS) is known to induce cell apoptosis by specifically inhibiting sphingosine kinase 1 (SPHK1) and modulating the activity of cellular ceramide levels. The present study investigated the effects and the mechanism(s) of action of DMS in human lung cancer cells. We found that DMS dose-dependently suppressed cell proliferation and induced cell apoptosis in the h...
