Insights

Sulfur mustard (SM) causes severe skin damage and increases cancer risk by alkylating DNA. This review explores poly(ADP-ribosyl)ation

Area of Science:

  • Toxicology
  • Molecular Biology
  • Chemical Warfare Agents

Background:

  • Sulfur mustard (SM) is a potent chemical warfare agent.
  • SM exposure causes severe skin blistering and long-term malignancy risks.
  • SM functions as a bifunctional alkylating agent, damaging DNA.

Purpose of the Study:

  • To review the role of poly(ADP-ribosyl)ation in cellular responses to SM-induced DNA damage.
  • To explore the potential of poly(ADP-ribosyl)ation inhibitors as therapeutic agents for SM injury.

Main Methods:

  • Literature review focusing on molecular mechanisms of SM toxicity.
  • Analysis of studies on DNA damage response pathways.
  • Investigation of poly(ADP-ribosyl)ation in the context of SM exposure.

Main Results:

  • SM induces DNA mono-adducts and di-adducts.
  • Poly(ADP-ribosyl)ation is a key cellular response to SM-induced DNA damage.
  • Inhibitors of poly(ADP-ribosyl)ation show therapeutic potential.

Conclusions:

  • Poly(ADP-ribosyl)ation plays a critical role in cellular and tissue responses to sulfur mustard.
  • Inhibitors targeting this pathway represent a promising therapeutic strategy for mitigating SM injury and its long-term consequences.

Sulfur Assimilation01:20

Sulfur Assimilation

Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to become...
Translesion DNA Polymerases02:10

Translesion DNA Polymerases

Translesion (TLS) polymerases rescue stalled DNA polymerases at sites of damaged bases by replacing the replicative polymerase and installing a nucleotide across the damaged site. Doing so, TLS allows additional time for the cell to repair the damage before resuming regular DNA replication.
TLS polymerases are found in all three domains of life - archaea, bacteria, and eukaryotes. Of the different classes of TLS polymerases, members of the Y family are fitted with specialized structures that...
Preparation and Reactions of Thiols02:33

Preparation and Reactions of Thiols

Thiols are prepared using the hydrosulfide anion as a nucleophile in a nucleophilic substitution reaction with alkyl halides. For instance, bromobutane reacts with sodium hydrosulfide to give butanethiol.
Preparation and Reactions of Sulfides02:26

Preparation and Reactions of Sulfides

Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.
Biosynthesis of Nucleic Acids01:28

Biosynthesis of Nucleic Acids

Nucleic acid biosynthesis is a fundamental biochemical process that produces the purine and pyrimidine nucleotides essential for DNA and RNA synthesis. This pathway maintains a balanced nucleotide pool, preventing imbalances that could jeopardize genetic integrity and cellular function. Given the crucial role of nucleotides, their synthesis is tightly regulated to ensure proper cellular homeostasis.Purine BiosynthesisThe biosynthesis of purine nucleotides begins with ribose-5-phosphate, a...
Spontaneous and Induced Mutations01:30

Spontaneous and Induced Mutations

Spontaneous mutations arise infrequently during DNA replication due to errors in the process. A key factor behind these errors is tautomeric shifts in nitrogenous bases, where bases transition from keto to enol forms or amino to imino forms. This shift can alter base-pairing rules, leading to mutations. Additionally, reactive oxygen species (ROS) arising from aerobic metabolism can damage DNA, resulting in depurination (loss of a purine base) or depyrimidination (loss of a pyrimidine base).
