What does vinblastine do to cancer cells?
Vinblastine works by stopping the cancer cells from separating into 2 new cells. So it blocks the growth of the cancer.
What causes apoptosis in cancer cells?
Apoptosis is either created by death receptors, which are called extrinsic pathway utilizing caspases 8 and 10. The other pathway is mitochondrial path or intrinsic pathway involving caspase 9. Recognizing involved mechanisms in cancer development is of great importance for developing neoplastic treatment.
Does apoptosis occur in cancer cells?
Cancer is one of the scenarios where too little apoptosis occurs, resulting in malignant cells that will not die. The mechanism of apoptosis is complex and involves many pathways.
Which stage of the cell cycle does vinblastine interfere with?
Vinblastine is cell cycle phase specific; it binds to microtubular proteins in the mitotic spindle, thereby preventing cell division during metaphase.
Is vinblastine a neurotoxic?
Vinblastine neuropathy is rare and mild; whereas, Vinorelbine and Vindesine can be associated with moderate neuropathy. We were unable to find any guidelines on how to modify treatment in the event of such severe neurotoxicity.
What is vinblastine and curcumin?
Curcumin, a major component of curry powder, which is a natural polyphenol product extracted from rhizoma curcumae longae, interacts with a specific binding site on microtubules. Vinblastine is an antitumor drug that induces microtubule depolymerization.
How do you induce apoptosis?
To stimulate apoptosis, one can increase the number of death receptor ligands (such as TNF or TRAIL), antagonize the anti-apoptotic Bcl-2 pathway, or introduce Smac mimetics to inhibit the inhibitor (IAPs).
What encourages apoptosis?
Beta-carotene, a carotenoid in orange vegetables, induces apoptosis preferentially in various tumor cells from human prostate, colon, breast and leukemia. Many more examples of dietary substan- ces inducing apoptosis of cancer cells are available.
Why are most cancer cells resistant to apoptosis?
The cancer cells evade apoptosis via various mechanisms. Theoretically, in order to resist apoptosis, cancer cells would upregulate anti-apoptotic signals (e.g. Bcl-2, Akt, Mcl-1, etc.) and downregulate pro-apoptotic signals (e.g. Bax, Bak, Bad, etc.), initiate and implicate faulty apoptosis, etc.
What are the side effects of vinblastine?
Vinblastine may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- constipation.
- nausea.
- vomiting.
- loss of appetite or weight.
- stomach pain.
- diarrhea.
- headache.
- dizziness.
How do you administer vinblastine?
Vinblastine should not be given intramuscularly, subcutaneously or intrathecally. The solution may be injected either directly into the vein or into the injection site of a running intravenous infusion. Injection of vinblastine sulfate may be completed in about one minute. FOR INTRAVENOUS USE ONLY.
