Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

2.0K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Notch Signaling Pathway03:14

Notch Signaling Pathway

4.2K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

The Retinoblastoma Gene

4.1K
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,...

Abnormal Proliferation02:23

Abnormal Proliferation

4.5K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

2.1K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Summary
This summary is machine-generated.

Downregulation of N-myc downstream-regulated gene 2 (NDRG2) in oral squamous cell carcinoma (OSCC) correlates with poor prognosis. Restoring NDRG2 may offer a potential therapeutic strategy for OSCC patients.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • N-myc downstream-regulated gene 2 (NDRG2) is a known tumor suppressor.
  • NDRG2 downregulation is linked to poor outcomes in several cancers.
  • The prognostic role of NDRG2 in oral squamous cell carcinoma (OSCC) is currently unclear.

Purpose of the Study:

  • To assess the prognostic value of NDRG2 downregulation in OSCC.
  • To investigate the mechanisms of NDRG2 downregulation in OSCC.
  • To determine the biological role of NDRG2 in OSCC progression.

Main Methods:

  • Immunohistochemical and in silico analyses of NDRG2 expression.
  • Correlation analysis between NDRG2 expression and clinicopathological data.
  • Investigation of NDRG2 knockdown effects and 5-aza-2'-deoxycytidine (5-aza-dC) treatment on OSCC cells.

Main Results:

  • NDRG2 expression was significantly downregulated in OSCC, frequently associated with DNA hypermethylation.
  • Low NDRG2 expression correlated with adverse clinicopathological features and worse survival in OSCC.
  • NDRG2 knockdown enhanced OSCC cell oncogenicity, while 5-aza-dC treatment restored NDRG2 mRNA levels.

Conclusions:

  • NDRG2 downregulation promotes OSCC progression and predicts a poor prognosis.
  • Restoration of NDRG2 expression presents a potential therapeutic avenue for OSCC.
