Summary
Plant-derived jasmonates show promising anti-cancer effects, selectively killing cancer cells and increasing lifespan in mice. These compounds offer new therapeutic hope, even against drug-resistant cancers.
Area of Science:
- Plant biochemistry
- Cancer biology
- Pharmacology
Background:
- Jasmonates, plant stress hormones, and their synthetic derivatives have demonstrated anti-cancer properties.
- These compounds exhibit selective cytotoxicity against cancer cells, sparing normal lymphocytes.
- Jasmonates are part of a growing class of plant-derived anti-cancer agents.
Purpose of the Study:
- To explore the anti-cancer mechanisms of jasmonates.
- To investigate the potential of jasmonates as novel cancer therapeutics.
- To highlight similarities between jasmonate effects on plant and cancer cells.
Main Methods:
- In vitro and in vivo studies on cancer models.
- Analysis of cellular mechanisms including ATP depletion, MAPK activity, and ROS generation.
- Evaluation of efficacy against drug-resistant cancer cells.
Main Results:
- Jasmonates increased lifespan in lymphoma-bearing mice.
- Selective cytotoxicity observed in cancer cells and chronic lymphocytic leukemia (CLL) cells.
- Three proposed mechanisms: bio-energetic (ATP depletion), re-differentiation (MAPK), and ROS-mediated apoptosis.
- Similarities noted between plant and cancer cell responses to jasmonates (cell death, proliferation suppression, ROS generation).
- Jasmonates induced death in drug-resistant cells (p53 mutation or P-glycoprotein over-expression).
Conclusions:
- Jasmonates represent a promising new class of anti-cancer agents.
- Further research into jasmonates could lead to novel cancer therapeutics.
- The study highlights the therapeutic potential of plant-derived compounds in oncology.

02:49Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

02:56Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
