Cancer is the class of chronic disease caused by irregular cell growth in the tissue or specific organ in the body due to the alternation of cell DNA.
The ovaries are oval-shaped ovum-producing reproductive organ formed part of women reproductive system that connects to the fallopian tubes and attaches to the outer layer of the uterus via the ovarian ligament. Usually, the left and right ovary take a turn to release an egg every month.
Ovarian cancer is medical a condition characterized by abnormal cells growth of ovarian cells that start on the surface of the inner lining of the ovary. Over time, the oversize tumor can travel a distance away to infect the nearby organ and tissue via the fluid and blood circulation.
According to the statistics provided by the American Cancer Society, ovarian cancer is one of the dealy reproductive cancer in women. Every year, the disease causes more deaths than any other cancer of the female reproductive system.
The lifetime risk of getting ovarian cancer is a woman is about 1 in 78.comapred to the lifetime of dying from ovarian cancer risk of 1 in 108.
The 5-year relative survival of all stages of ovarian cancer is 47%. However, women with ovarian cancer diagnosed at the localized stage have a 5 years survival rate of over 92%.
The exact causes of ovarian cancer are not identified. However, epidemiological studies suggested that women who have endometriosis, genetic preposition such as BRCA1 and BRCA2 gene, acquired genetic mutation such as the TP53 tumor suppressor gene are susceptible to the risk of the development of the disease.
The Canadian Cancer Society in the evaluation of the risk of ovarian cancer in women who are never being pregnant or giving birth wrote, "Women who have never been pregnant have a higher risk of developing ovarian cancer than women who have been pregnant".
And, "Researchers think that the lower risk maybe because the hormones that are present during pregnancy have a protective effect. It is possible that the higher risk in women who have never been pregnant is linked to the factors that may make it difficult for her to become pregnant".
In other words, women who have at least one pregnancy are at a lower risk of ovarian cancer compared to women who do not.
On finding a natural ingredient for the prevention and treatment of cancers, Z-Ligustilide, the most potent bioactive component of Angelica Sinensis on ovarian cancer cells.
Angelica or Dang Qui is a herb of Genus Angelica from the family Apiaceae, indigenous to China.
The herb has been used as a Queen herb in traditional Chinese medicine antispasmodic and vasodilatory agent, and to balance the hormones in women for a normal menstrual cycle and menstruation and strengthen heart, spleen, kidneys, and liver for both men and women, etc. In other words, it is used to treat gynecological ailments, fatigue, mild anemia, and high blood pressure. It has analgesic, anti-inflammatory, etc.
According to the tested analysis,
* Z-Ligustilide resulted in apoptotic cell death by inducing oxidative stress on mitochondria.
* Furthermore. Z-Ligustilide enhanced the mitochondrial superoxide formation.
* NRF2, the antioxidant enzymes enhancer, and downstream antioxidant defense genes were elevated by tZ-Ligustilide in OVCAR-3 cells at the epigenetic level.
* Most importantly, NRF2 knockdown by siRNA resulted in increased cell death by Z-Ligustilide in ovarian cancer cells.
Based on the findings, researchers said, " Our result demonstrated the pro-survival role of NRF2 in Z-Ligustilide induced ovarian cancer cell death".
Taken altogether, angelica sinensis may be considered an antioxidant remedy for the prevention and treatment of human ovarian cancer, pending to the confirmation of the larger sample size and multicenter human study.
