Abstract

Insights

Researchers identified novel bacteriocins from Lactobacillus salavarius with potential anticancer properties. One bacteriocin, Lsl_0510, showed significant binding affinity to key cancer targets, indicating promise for new cancer therapeutics.

Area of Science:

  • Microbiology
  • Biochemistry
  • Cancer Research

Background:

  • Bacteriocins, antimicrobial peptides from bacteria, exhibit potential antineoplastic activities.
  • Lactobacillus salavarius (Lsl) genome was screened for novel bacteriocins.
  • Azurin, a known bacteriocin with cytostatic and apoptotic effects, served as a control.

Purpose of the Study:

  • To identify and characterize bacteriocins from Lactobacillus salavarius with potential anticancer properties.
  • To evaluate the functional similarity of identified bacteriocins to Azurin.
  • To assess the binding affinity of bacteriocins to cancer-related targets: p53, Retinoblastoma 1 (Rb1), and Androgen Receptor (AR).

Main Methods:

  • Genome-wide scanning of Lactobacillus salavarius for putative bacteriocins.
  • Functional annotation and characterization of identified bacteriocins.
  • Molecular screening and binding affinity assays against p53, Rb1, and AR.

Main Results:

  • Three bacteriocins (Lsl_003, Lsl_0510, Lsl_0554) were identified and functionally characterized.
  • These bacteriocins demonstrated functional properties similar to Azurin.
  • Lsl_0510 exhibited the highest binding affinity to p53, Rb1, and AR.

Conclusions:

  • Lactobacillus salavarius harbors bacteriocins with promising anticancer potential.
  • Lsl_0510 is a strong candidate for developing novel cancer therapeutics due to its high binding affinity to key cancer targets.
  • Further research into Lsl_0510 could lead to new strategies for cancer treatment.

Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
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 specific...

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...

Selectins

Cell adhesion is  an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...

Biological Methods for Microbial Control

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...
