Naturally occurring apigenin facilitates the death of cancer cells
Resistance of tumor cells to chemotherapy is the leading cause of death among cancer patients.
Now a study reports that ingesting apigenin – a naturally occurring dietary agent found in vegetables and fruit – improves cancer cells’ response to chemotherapy.
It has been found in the study that apigenin localizes tumor suppressor p53, a protein, in the cell nucleus. This step is a necessary step for killing the cell that results in some tumor cells responding to chemotherapy.

The study, published this week in the online early edition of the Proceedings of the National Academy of Sciences, provides a novel approach to conquer tumor resistance to chemotherapy, and suggests an avenue for developing safe chemotherapy via naturally occurring agents.
In normal condition, the cells have low levels of p53 diffused in their cytoplasm and nucleus. On damage of DNA in the nucleus, p53 moves to the nucleus where it activates genes that stop cell growth and cause cell death.
p53 ensures that cells with damaged DNA are killed.
Apigenin is able to activate p53 and transport it into the nucleus, resulting in a stop to cell growth and cell death.
Apigenin is mainly found in fruits (including apples, cherries, grapes), vegetables (including parsley, artichoke, basil, celery), nuts and plant-derived beverages (including tea and wine).
Its growth inhibitory properties have been found in several cancer lines, including breast, colon, skin, thyroid and leukemia cells. It has also been shown to inhibit pancreatic cancer cell proliferation.
The study advocates the inclusion of vegetables and fruit in our daily diet to help prevent cancer.
Before proceeding to examination in any joint pathology, it is important to take a good history of the illness. It begins with questions like when did it begin, where is the pain or is there any swelling. History of trauma, tuberculosis, typhoid, exposure to venereal disease is important.
According to a recently published study, nicotine could play a role in the development and growth of tumors in breast cancer.
A new touch up software has been developed which uses a mathematical formula to alter the original form into a theoretically more attractive version, while maintaining what programmers call an unmistakable similarity to the original.
TScorpion venom is being used to attack tumor cells in the body. It has been found that a non-toxic extract from the venom specifically seeks out and locks onto malignant cells after it is injected into the body.
