The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.2K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Cancers Originate from Somatic Mutations in a Single Cell

12.4K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Skin Cancer01:30

Skin Cancer

4.3K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.8K
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...

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

7.7K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Cancer-Critical Genes II: Tumor Suppressor Genes

7.6K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Summary
This summary is machine-generated.

Medullary thyroid cancer (MTC) arises from C cells, often seen in multiple endocrine neoplasia (MEN) syndromes. Early detection via calcitonin and RET proto-oncogene testing, followed by prophylactic thyroidectomy, significantly improves patient prognosis.

Area of Science:

  • Endocrinology
  • Oncology
  • Genetics

Context:

  • Parafollicular C cells can develop into medullary thyroid cancer (MTC), a condition observed even in early childhood among patients with multiple endocrine neoplasia (MEN) types 2A and 2B.
  • Basal calcitonin and carcinoembryonic antigen (CEA) serve as crucial biomarkers for diagnosing and monitoring MTC.
  • The RET proto-oncogene exhibits a strong genotype-phenotype correlation, enabling risk assessment for MTC development.

Purpose:

  • To summarize the progression of C cells to MTC, diagnostic markers, prognostic factors, and the role of prophylactic thyroidectomy in MEN syndromes.

Summary:

  • Medullary thyroid cancer (MTC) originates from parafollicular C cells and can manifest early in life, particularly in individuals with MEN 2A and 2B.
  • Calcitonin and CEA are key tumor markers for MTC diagnosis and management.
  • Prognosis is linked to diagnostic stage and RET proto-oncogene mutations, guiding risk stratification and prophylactic thyroidectomy decisions.

Impact:

  • Highlights the importance of genetic screening for RET proto-oncogene mutations in MEN syndromes.
  • Emphasizes the critical role of risk-stratified prophylactic thyroidectomy in improving outcomes for gene mutation carriers.
  • Underscores the value of calcitonin and CEA in early MTC detection and monitoring.
