Cancer-Critical Genes II: Tumor Suppressor Genes

7.4K
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...

Tumor Progression02:07

Tumor Progression

6.3K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Structures of the Endocrine System

7.6K
The intricate framework of the endocrine system encompasses a diverse array of glands, with their target tissues and organs strategically distributed throughout the body. Central to this network are the endocrine glands, specialized structures that lack ducts and release hormones directly into the interstitial fluid. Notably, the hypothalamus, a vital neuroendocrine organ situated in the brain, governs neural functions and serves as a potent source of hormonal regulation. Near the hypothalamus...

Metastasis02:30

Metastasis

5.5K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Area of Science:

  • Endocrinology
  • Oncology
  • Genetics

Background:

  • Multiple endocrine neoplasia (MEN) syndromes are inherited disorders characterized by tumors in two or more endocrine glands.
  • MEN type 2 is a common subtype, typically involving the thyroid, adrenal glands, and parathyroid glands.
  • While paragangliomas are rare in MEN type 2, this case presents an unusual association.

Observation:

  • A rare case of multiple endocrine neoplasia (MEN) type 2 was identified.
  • The patient presented with an unusual combination of tumors.
  • These included medullary thyroid carcinoma (MTC), hyperparathyroidism, and pheochromocytoma, alongside a paraganglioma.

Findings:

  • The study documents a rare co-occurrence of paraganglioma with MTC, hyperparathyroidism, and pheochromocytoma within the context of MEN type 2.
  • This specific tumor constellation is infrequently reported in MEN type 2 patients.
  • The findings highlight the diverse clinical manifestations of MEN syndromes.

Implications:

  • This case expands the known spectrum of tumor associations in MEN type 2.
  • Understanding these rare combinations is crucial for accurate diagnosis and comprehensive patient management.
  • Further research into the genetic and molecular underpinnings of these rare MEN presentations is warranted.
