Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein.
NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Factors Affecting Drug Biotransformation: Biological

Biological factors significantly impact drug metabolism, influencing drug clearance, efficacy, and potential toxicity.
Species differences: Variations in enzyme systems across species can cause disparities in drug metabolism. For instance, humans may metabolize certain drugs faster than rodents, altering therapeutic effects.
Strain differences: Genetic variations within a species can result in differing enzyme activity, impacting drug response and toxicity. For example, some mouse strains may...
Chirality in Nature02:30

Chirality in Nature

Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid. The...

Area of Science:

  • Phytochemistry
  • Pharmacology
  • Nutraceuticals

Background:

  • Turmeric (Curcuma longa) is a spice known for its vibrant yellow color, primarily due to curcuminoids.
  • Curcuminoids, including curcumin, demethoxycurcumin, and bisdemethoxycurcumin, are recognized food colorants (E100).
  • Emerging research highlights the significant health-promoting properties of curcuminoids.

Purpose of the Study:

  • To review the transition of curcuminoids from traditional food applications to modern biological regulators.
  • To explore the documented health benefits and mechanisms of action of curcuminoids.
  • To discuss the potential of synthetic curcumin analogues.

Main Methods:

  • Literature review of traditional uses, food additive regulations, and scientific studies on curcuminoids.
  • Analysis of research on the biological activities, including antioxidant, anti-inflammatory, neuroprotective, and chemopreventive effects.
  • Examination of studies investigating the influence of curcuminoids on gene expression and epigenetic mechanisms.

Main Results:

  • Curcuminoids possess potent antioxidant and anti-inflammatory activities.
  • Evidence suggests neuroprotective, chemopreventive, and anticancer potential of curcuminoids.
  • Curcuminoids modulate gene expression and epigenetic pathways.
  • Synthetic analogues also demonstrate biological efficacy.
