Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.9K
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...

Autophagy01:27

Autophagy

5.8K
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

The Thyroid Gland01:23

The Thyroid Gland

7.6K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Functions of Thyroid Hormones

5.6K
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...

Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

7.8K
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...

Cancer02:18

Cancer

54.2K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Area of Science:

  • Oncology
  • Cellular Biology
  • Molecular Medicine

Background:

  • Thyroid cancer is a common endocrine malignancy, with advanced forms like metastatic, radioiodine-refractory, or anaplastic types having poor prognoses.
  • Molecularly targeted therapies, including tyrosine kinase inhibitors (TKIs), are transforming treatment for radioiodine-refractory differentiated thyroid cancers (RR-DTCs).
  • Drug resistance and adverse effects of TKIs necessitate the development of synergistic treatment strategies.

Purpose of the Study:

  • To summarize recent evidence on the role of autophagy in thyroid cancer.
  • To explore how autophagy influences drug resistance and the dedifferentiation process in thyroid cancers.
  • To highlight future research perspectives for autophagy-targeted therapeutic strategies.

Main Methods:

  • Review of current scientific literature and research findings.
  • Analysis of the complex role of autophagy in thyroid cancer development and treatment.
  • Synthesis of evidence regarding autophagy's involvement in drug resistance and radioiodine therapy outcomes.

Main Results:

  • Autophagy is implicated in protecting cells from stressors but also in cancer development and progression.
  • Autophagy significantly mediates drug resistance to small-molecule therapeutics in thyroid cancer.
  • Autophagy influences the dedifferentiation of thyroid cancer cells and impacts radioiodine therapy efficacy.

Conclusions:

  • A deeper understanding of autophagy's role in thyroid cancer pathogenesis is crucial for improving patient outcomes.
  • Targeting autophagy presents a promising avenue for developing novel therapeutic strategies to overcome TKI resistance.
  • Future research should focus on elucidating the intricate mechanisms of autophagy in thyroid cancer for clinical translation.
