Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

4.9K
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...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

4.7K
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

2.6K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.5K
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.
There are several types of targeted therapies against...

Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

4.4K
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...

Drugs that Stabilize Microtubules01:15

Drugs that Stabilize Microtubules

2.0K
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

Area of Science:

  • Endocrinology
  • Oncology
  • Pharmacology

Background:

  • Thyroid cancer (TC) is the most common endocrine malignancy with rising incidence.
  • Current treatments for differentiated thyroid cancers (DTC) are insufficient for recurrent or poorly differentiated cases.
  • There is a critical need for novel therapeutic agents for challenging thyroid cancer cases.

Purpose of the Study:

  • To investigate the anti-cancer activity of flavopereirine, a compound from Geissospermum vellosii, against human thyroid cancer (TC).
  • To elucidate the mechanisms underlying flavopereirine's effects on TC cells.
  • To validate the efficacy of flavopereirine in vivo.

Main Methods:

  • In vitro studies on human TC cell lines.
  • Analysis of cell cycle arrest, apoptosis, and autophagy modulation.
  • In vivo validation using a zebrafish model.

Main Results:

  • Flavopereirine significantly inhibited human TC cell growth.
  • The compound induced cell cycle arrest and promoted apoptosis.
  • Flavopereirine modulated autophagy and affected key signaling pathways.
  • In vivo studies confirmed flavopereirine's efficacy against human TC cells.

Conclusions:

  • Flavopereirine demonstrates potent anti-human TC activity.
  • The compound effectively targets multiple cancer hallmarks in TC.
  • Flavopereirine represents a promising therapeutic candidate for human thyroid cancer treatment.
