Prostate cancer is a condition characterized by abnormal cells growth in prostate tissue.
Most cases of prostate cancer start in the cells on the surface of the inner lining of the prostate tissue.
Most prostate cancers are slow growing. Enlarged prostate and prostate cancer may be detected during the Physical (rectum) exams.
Contrary to popular belief, as of today, prostate cancer no long is a disease of aging male, it has a tendency to affect the younger age population, particularly to that of age group 20 -40.
According to the statistic, most men diagnosed with prostate cancer survival or died due to another disease instead of prostate cancer. In the US, approximately over 2.9 million men in who have been diagnosed with prostate cancer at some point are still alive today.
Also, 1 man in 9 will be diagnosed with prostate cancer during his lifetime and the disease is the most common cancer in American men.
Researchers do not know the exact causes of prostate cancer. Epidemiological studies suggested age, family history, being obesity or obese, genetic preposition, particularly a poor diet with high saturated and trans fat, red meat and processed food and low fruits and vegetables and whole grain are associated to the onset of prostate cancer.
Some researchers suggested ethnicity is a predictor involved the development of the disease due to a number of genetic mutations.
Dr. P Kheirandish said, "It is recognized that the risk of prostate cancer is higher in black men than in white men worldwide" and "...Compares data from the United States (US), which suggest that African-American men have a 60% higher risk for developing prostate cancer with poorer prognosis in comparison with their white counterparts, with similar studies carried out in the United Kingdom (UK) and also in African and Caribbean countries".
The results clearly proposed if you are black men, you are associated with a substantially higher risk of prostate cancer. However, if you follow a healthy diet and lifestyle, your risk of the prostate can be reduced compared to other men in the same race group.
Cascara sagrada is a species of buckthorn, genus Rhamnus, belonging to the family Rhamnaceae, native to western North America.
The herbal medicine bark has been used in traditional medicine for gastrointestinal support. and it is thought to have a laxative and natural cleansing, etc..
The chemical constituents of Cascara Sagrada include Aloe-emodin, Anthrquinone glycosides (Barbaloin Cascarosides A, B, C and D ChrysaloinFrangul), Chrysophanol, Emodin, Heterodianthrones palmitin A, B, and C, dianthrones, Oxanthrone, Rhein, Tannins, etc.
The Korea Research Institute of Bioscience and Biotechnology, in the concern of mTOR Complex 2, a protein complex that regulates cellular metabolism may involve in the stimulation of the onset of prostate cancer, examined the effect of Aloe-emodin natural compound found in Cascara Sagrada and Aloe effect in prostate cancer cell line PC3.
Treatment of Aloe-emodin inhibited both proliferation and anchorage-independent growth of PC3 cells through a number of mechanisms, including the regulation of cellular metabolism, proliferation, and migration.as well as tumor-promoting.
Furthermore, in vivo in an athymic nude mouse model, injection of Aloe-emodin also exhibited tumor suppression effects.
The finding strongly suggested Aloe-emodin suppresses prostate cancer progression by targeting mTORC2, a protein complex which plays an important role in prostate cancer development.
The examination of the Emodin (ED), an anthraquinone derivative found in Cascara Sagrada effect in inhibiting the proliferation, induce apoptosis, suppress angiogenesis, impede metastasis, and enhance chemotherapy, researchers investigated the mechanism of ED related to the regulation of gene expression that affects cellular migration and invasion in prostate cells.
In CXCR4/CXCL12 gene expression, involved in promoting invasion and metastasis in prostate tumor, injection of ED reduced the cancer proliferation and metastasis through inhibiting the CXCR4 expression.
Futhermore, researchers discovered, ED also reduced the expression of HER2 without affecting cell viability in tumor cells.
Moreover, The suppression of CXCR4 expression by ED was found to correlate with the inhibition of CXCL12-induced migration and invasion of DU145, a human prostate cancer cell line.
Additional differentiation of the efficacy of ED, researchers also found the inhibition of the expression of CXCR4 was associated with the mRNA expression through a protein (NF-κB ) which controls the transcription of DNA, cytokine production and cell survival.
Dr.Ok S, the lead researcher wrote in the final report, "ED is a novel blocker of CXCR4 expression and, thus, has enormous potential as a powerful therapeutic agent for metastatic cancer".
Taken altogether, Herbal Cascara Sagrada (Rhamnus purshiana) processed bioactive compound Aloe emodin and emodin may be considered a functional herb for the prevention and combined with other primary medicine for the treatment of prostate cancer.
