Abstract

Insights

The microRNA let-7f-5p suppresses colon cancer cell growth. Rotundic Acid (RA) is a natural compound that enhances let-7f-5p

Area of Science:

  • Molecular oncology
  • Natural product chemoprevention

Background:

  • MicroRNAs regulate gene expression and are implicated in cancer.
  • let-7f-5p is downregulated in colorectal cancer (CRC).
  • Natural products offer potential chemopreventive agents.

Purpose of the Study:

  • Investigate the role of let-7f-5p in human colon cancer cell line Caco2 proliferation.
  • Explore natural compounds as chemopreventive agents for CRC.

Main Methods:

  • Manipulated let-7f-5p levels in Caco2 cells using mimics and inhibitors.
  • Assessed cell proliferation, migration, cell cycle, and colony formation.
  • Evaluated protein levels of AMER3 and SLC9A9 via western blotting.

Main Results:

  • let-7f-5p exhibited a suppressive function on Caco2 cell proliferation.
  • Rotundic Acid (RA) antagonized proliferation, wound healing, and colony formation.
  • RA's inhibitory effect may involve suppressing let-7f-5p targets AMER3 and SLC9A9.

Conclusions:

  • let-7f-5p acts as a tumor suppressor in Caco2 cells.
  • RA modulates let-7f-5p's effect on cell proliferation.
  • RA shows potential as a chemopreventive agent for CRC.

GPCRs Regulate Adenylyl Cylase Activity01:09

GPCRs Regulate Adenylyl Cylase Activity

Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

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...

Negative Regulator Molecules01:23

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Cell Specific Gene Expression01:58

Cell Specific Gene Expression

Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
