Herbal Cascara sagrada may be the next pharmaceutical target to identify the single ingredient for the treatment of non-small cell lung cancer (NSCLC), some scientists suggested.
Lung cancer is a medical condition characterized by abnormal growth of the cells in the lung's tissue.
The most common form of primary lung cancers is derived from epithelial cells.
According to the statistics provided by the American Cancer Society, in the US, lung cancer is the leading cause of cancer deaths.
In 2007, lung cancer causes the death of 158,683 people, including 88,329 men and 70,354 women.
Most common types of lung cancers include
* Squamous-cell carcinoma often found in an outer area of the lung,
* Large-cell carcinoma found in the center of the lung by an air tube
* Adenocarcinoma found in any part of the lung.
Non-small cell lung cancer, the most common type of lung cancer, usually grows and spreads methodically and predictably.
The most common risk factors of non-small cell lung cancer (NSCLC) are long term smoking and people exposed to long-term second-hand smoke.
Dr. Ryo Maeda MD, the lead scientists in the study to investigate the association between cigarette smoking and clinicopathological characteristics of patients with non-small cell lung cancer (NSCLC) and to evaluate its significance as a predictor of recurrence after resection showed that
* The 5 years of the survival rate of never and ever smokers in patients with stage I is 92%, compared to 76%, in smokers.

At the final report, the doctors wrote, "Smoking history showed the different impact on postoperative recurrence in patients with NSCLC between stage I and stages II and III, and depending on histology in stage I patients" and "Disease stages should be considered while evaluating smoking history as a predictor of recurrence".
These results not only indicated smoking has a strong impact on the increased incidence of non-small cell lung cancer (NSCLC) and but also reduces years of the survival.
Compared to the effect of cisplatin, a chemo drug, Emodin, exposure to the human NSCLC cells to emodin decreased cisplatin-elicited in the inhibition of the metaplasia and tumor development and increased the inability of a protein associated to cell DNA repaired.
Cascara sagrada is a species of buckthorn, genus Rhamnus, belonging to the family Rhamnaceae, native to western North America.
The plant bark has been used in traditional medicine for gastrointestinal support. and it is thought to have a laxative and natural cleansing, etc., effect.
Besides the main compound of anthraquinones, Cascara sagrada also contains anthraquinone glycosides, (emodin, frangulin, iso-emodin, aloe-emodin, and chrysophanol), rhein, aloin, malic acid, tannic acid, cascarosides A, B, C, and D, and hydroxy anthracene derivatives (HAD), etc.
On finding a natural ingredient for the treatment of nonsmall cell lung cancer, researchers examined the effect of Emodin, a tyrosine kinase inhibitor is a natural anthraquinone derivative found in the roots and rhizomes of numerous plants including herbal Cascara Sagrada.

Further analysis of the Emodin effect on the non-small cell lung cancer (NSCLC) scientists at the Hsinchu Hospital investigates the role of ERCC1 and Rad51 in emodin-mediated cytotoxicity in human non-small cell lung cancer (NSCLC) cells.
Where ERCC1 is a protein associated with cells repair and DNA recombination and RAD51 is a protein associated with the assists in repair of DNA double-strand breaks.
Injection of Emodin showed a reduction of the expression of ERCC1 and Rad51 protein levels as well as mRNA levels in four different NSCLC cell lines correlated with the inactivation of the MKK1/2-ERK1/2 pathway involving cells proliferation.
The result suggested that application of Emodin exerts the similar effect as those of U0126, an MKK1/2 inhibitor used in conventional medicine for the inhibition of cellular ERCC1 and Rad51 protein and mRNA levels.
Taken altogether, herbal Cascara Sagrada processed the bioactive compound Emodin may be considered a functional herb for the prevention and an adjunct therapy combined with the primary medicine for the treatment of non-small cell lung cancer (NSCLC)
