Insights

MicroRNA-483 (miR-483) suppresses colon cancer growth and migration by targeting TRAF1. This finding suggests miR-483 as a potential therapeutic target for colorectal cancer treatment.

Area of Science:

  • Molecular Biology
  • Oncology
  • Genetics

Background:

  • MicroRNAs regulate human growth and development.
  • MicroRNAs are implicated in colorectal cancer pathogenesis.

Purpose of the Study:

  • To elucidate the biological function of miR-483 in colorectal cancer.
  • To identify the direct target gene of miR-483.

Main Methods:

  • Cell proliferation was assessed using Edu assays.
  • Cell migration was evaluated by transwell assays.
  • Target gene prediction and validation involved target scan software and a dual fluorescence reporter system.

Main Results:

  • miR-483 mimic significantly inhibited colon cancer cell proliferation and migration.
  • TRAF1 was identified as a direct target gene of miR-483 in SW480 cells.

Conclusions:

  • miR-483 acts as a colorectal cancer suppressor.
  • miR-483 inhibits cell proliferation and migration, potentially by targeting TRAF1.
  • miR-483 represents a potential therapeutic target for colorectal cancer.

Cancer Cell Migration through Invadopodia

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,...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

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...

Cell Migration01:19

Cell Migration

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Cell Migration

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

The Colonization of Land02:22

The Colonization of Land

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...
