Herbal Angelica, Processes Apoptotic and Anti Proliferative Function in Vitro

Cancer is a group of medical and chronic diseases characterized by cell growth disorderly and uncontrollably in the tissue of specific organs in the body.


Over time, the alternative cells induced tumor may become progressively worse and damage other healthy tissues, depending on the grade of the tumor.

At the later stage, the most invasive tumor can induce secondary metastasis by spreading to other organs in the body via lymph or blood.

According to the National Cancer Institute, approximately 38.4% of men and women will be diagnosed with cancer at some points during their lifetimes, according to the data from 2013–2015.

In 2017, an estimated 15,270 children and adolescents ages 0 to 19 were diagnosed with cancer and 1,790 died of the disease.


In cancer, antiproliferation is a process in which the cancer cells are killed or limited to grow through many mechanisms, including the use of chemo drugs.

In the immune perspective, anti-proliferation can be carried out by activating the genes associated with cancer suppression, programming cell death,.... and cell cycle arrest.

A suppressive gene, such as pro-apoptotic p53 induces cancer cell death through cell cycle arrest. In other words, the gene inhibits tumor growth by interrupting the cancer cell cycle division.

In the programmed cell death gene, such as BCL-2 induce cell death by either inducing apoptosis. In other words, If cells are no longer needed or damaged, activating an intracellular death program will cause cell death.

In phytochemicals, anti-proliferation can also be carried out by antioxidants in which they stimulate the free radicals overexpression to induce toxicity to tumor cells without causing harm to the nearby healthy 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.

On finding a potential compound for the prevention and treatment of cancer, researchers examined the effects of Angelica phytochemical (+)-4'-decanoyl-cis-khellactone and (+)-3'-decanoyl-cis-khellactone from A. purpuraefolia on cell proliferation and apoptotic cell death.


In 4 breast (MDA-MB-231, MCF-7, HS578T, and T47D), three cervical (HeLa, SiHa, and C33A) cancer cell lines, and NIH 3T3 normal cells used for the experiment, researchers found that
* (+)-4'-decanoyl-cis-khellactone and (+)-3'-decanoyl-cis-khellactone treatment suppresses the growth and proliferation of cancer cells at a relatively low concentration (<10 μg/ml).



* The phytochemical also induces cancer cell apoptosis at a high concentration (>50 μg/ml).

* At the concentration of 10 μg/ml, the chemical compounds also exerted a strong cell cycle arrest in the S/G2 phase.


Furthermore, according to the Western blot analysis, the concentration higher than 50 μg/ml of (+)-4'-decanoyl-cis-khellactone increased the large percentage of apoptotic cells in a time-dependent manner.


Interestingly, while the (+)-4'-decanoyl-cis-khellactone using both extrinsic and intrinsic pathways to induce apoptosis, the but (+)-3'-decanoyl-cis-khellactone uses only an intrinsic pathway for the same results.



In other words, the (+)-4'-decanoyl-cis-khellactone and (+)-3'-decanoyl-cis-khellactone also inhibited the in vitro proliferation of six other human breast and cervical cancer cell lines with different pathways.


Based on the evidence, researchers said, "Our data strongly suggest that (+)-4'-decanoyl-cis-khellactone and (+)-3'-decanoyl-cis-khellactone act as an anti-cancer supplement particularly against breast and cervical cancers by inducing cell cycle arrest in the S/G2 phase and caspase-dependent apoptosis at relatively low and high concentrations, respectively".



Taken altogether, Herbal Angelica processes anti-proliferative activity against cancer, pending larger sample size and multicenter human study.
