Summary

This summary is machine-generated.

Ubiquitin-specific protease 33 (USP33) promotes esophageal squamous cell carcinoma (ESCC) migration and metastasis by stabilizing integrin α6. Targeting USP33 offers a potential therapeutic strategy for ESCC treatment.

Area Of Science

  • Oncology
  • Molecular Biology
  • Biochemistry

Background

  • Deubiquitinating enzymes (DUBs) are implicated in cancer development.
  • Ubiquitin-specific protease 33 (USP33) influences tumor cell behaviors, but its role in esophageal squamous cell carcinoma (ESCC) is not fully understood.

Purpose Of The Study

  • To investigate the biological functions and mechanisms of USP33 in ESCC progression.
  • To determine if USP33 is a potential therapeutic target for ESCC.

Main Methods

  • Analysis of USP33 expression in ESCC using bioinformatics, RT-PCR, and immunohistochemistry.
  • Evaluation of cell adhesion, spreading, migration, and metastasis.
  • Investigation of USP33 interaction with integrins via immunoprecipitation and deubiquitination assays.

Main Results

  • USP33 expression correlates positively with advanced TNM stage, T classification, and poor prognosis in ESCC patients.
  • USP33 enhances laminin-dependent adhesion, spreading, and migration of ESCC cells.
  • USP33 promotes ESCC cell migration and metastasis by deubiquitinating and stabilizing integrin α6.

Conclusions

  • USP33 promotes ESCC cell migration and metastasis through a novel mechanism involving integrin α6.
  • USP33 represents a promising therapeutic target for esophageal squamous cell carcinoma.

Cancer Cell Migration through Invadopodia 01:35

2.3K

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Integrins 01:10

3.8K

Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal 01:22

2.2K

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Role Of Notch Signalling In Intestinal Stem Cell Renewal 01:12

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...

Activation of Integrins 01:15

3.3K

Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...

Receptor Downregulation in MVBs 01:15

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...
