Summary
Etoposide and vincristine demonstrate significant anticancer effects in thyroid carcinoma cell lines. Trichostatin A also shows promise as a potential innovative therapy for refractory thyroid cancers.
Area of Science:
- Oncology
- Pharmacology
Background:
- Thyroid carcinomas are predominantly well-differentiated with good prognosis.
- Undifferentiated and refractory thyroid carcinomas have limited therapeutic options.
- Novel treatments are crucial for advanced thyroid cancer cases.
Purpose of the Study:
- To evaluate the in vitro anticancer efficacy of 20 chemotherapy and hormonal therapy drugs.
- To identify potential novel therapeutic agents for refractory thyroid carcinomas.
- To assess drug sensitivity across various thyroid carcinoma cell lines.
Main Methods:
- Utilized the adenosine-triphosphate-based chemotherapy response assay (ATP-CRA) for in vitro chemosensitivity testing.
- Tested 20 different chemotherapy and hormonal therapy drugs against 8 thyroid carcinoma cell lines.
- Analyzed tumor inhibition rate (TIR) and half maximal inhibitory concentration (IC50) to determine drug effectiveness.
Main Results:
- Etoposide and vincristine exhibited the highest chemosensitivity in follicular and Hürthle cell carcinoma lines, respectively.
- Trichostatin A demonstrated a favorable anticancer effect with a low IC50 in follicular carcinoma cells.
- These drugs showed significant potential in inhibiting thyroid carcinoma cell growth.
Conclusions:
- Etoposide and vincristine are identified as active anticancer drugs for thyroid carcinoma cell lines.
- Trichostatin A emerges as a promising candidate for future refractory thyroid cancer therapy.
- These findings suggest potential innovative treatment strategies for challenging thyroid cancer cases.

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
02:57Targeted Cancer Therapies
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.

02:50Combination Therapies and Personalized Medicine
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

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...
01:20Synthesis and Regulation of Thyroid Hormones
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
