Ashwagandha Processes Anti-Proliferative activity Against Cancer

By Kyle J. Norton

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.

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.

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.

On finding a potent compound that processes the anti-cancer activity, researchers examined the effects of Withaferin A (WA) in W.somnifera, the secondary metabolite anti-proliferative effects in a number of human cancer cell lines.


Ashwagandha also is known as Withania somnifera is a nightshade plant in the genus of Withania, belonging to the family Solanaceae, native to the dry parts of India, North Africa, Middle East, and the Mediterranean.

The herbal medicine has been considered as Indian ginseng and used in Ayurvedic medicine over 3000 years to treat tumors and tubercular glands, carbuncles, memory loss, and ulcers and considered as anti-stress, cognition-facilitating, anti-inflammatory, and anti-aging herbal medicine.

According to the results from the flow cytometry and western blot analysis, MG-63 and U2OS human osteosarcoma cell lines treated with different concentrations of WA showed a significant inhibition and proliferation of the cancer cells.

Furthermore, WA exerting anti-cancer activity was attributed to induce cell cycle arrest at the G2/M phase, by inhibiting proteins (cyclin B1, cyclin A, Cdk2 and p-Cdc2 (Tyr15)) associated cellular mitosis of cyclin A and multiple cell cycle division and steps, and DNA damage markers such as levels of p-Chk1 (Ser345) and p-Chk2.

Based on the findings, researchers said, "....the antiproliferative potential of WA was associated with the induction of cell cycle arrest at the G2/M phase, which was a result of the attenuation of the expression levels of G2/M checkpoint proteins".

Taken altogether, Ashwagandha may be considered a functional herb for the prevention and treatment of cancer proliferation, pending to the result of larger sample size and multicenter study
