Insights

Researchers found that Lactobacillus fermentum UCO-979C significantly inhibited Helicobacter pylori colonization in gerbils. This human gastric probiotic shows strong potential for combating this common, high-priority pathogen.

Area of Science:

  • Microbiology
  • Gastroenterology
  • Probiotics

Background:

  • Helicobacter pylori is a high-priority pathogen with increasing prevalence.
  • Developing effective bacterial probiotics against H. pylori remains a clinical challenge.

Purpose of the Study:

  • To evaluate the in vivo anti-H. pylori efficacy of the human gastric probiotic strain Lactobacillus fermentum UCO-979C.
  • To assess the protective activity of L. fermentum UCO-979C against H. pylori colonization in a Mongolian gerbil model.

Main Methods:

  • A Mongolian gerbil model (Meriones unguiculatus) was employed.
  • Animals were administered L. fermentum UCO-979C and/or H. pylori SS1.
  • H. pylori colonization levels in the antrum were quantified to assess probiotic activity.

Main Results:

  • Lactobacillus fermentum UCO-979C demonstrated significant inhibition of H. pylori SS1 colonization.
  • A reduction of up to 87% in gastric antrum colonization by H. pylori was observed.
  • The probiotic strain showed strong anti-H. pylori activity in vivo.

Conclusions:

  • Lactobacillus fermentum UCO-979C exhibits potent probiotic properties against Helicobacter pylori.
  • This strain is a promising candidate for further development as a therapeutic agent against H. pylori infections.

Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy

Helicobacter pylori, a resilient gram-negative bacterium, can thrive in the stomach's harsh, acidic environment. Infection with H. pylori leads to a cascade of events within the stomach lining. One of the critical disruptions caused by this bacterium is the interference with somatostatin production, a hormone responsible for regulating acid secretion. This interference tips the balance, escalating acid secretion and diminishing bicarbonate levels. This imbalance compromises the defensive...

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!

Enzyme Inhibition01:30

Enzyme Inhibition

Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Eukaryotic Transcription Inhibitors01:52

Eukaryotic Transcription Inhibitors

Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a...

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...
