Hypothesis: Long non-coding RNA is a potential target of mycotoxins

Area of Science:

• Toxicology
• Molecular Biology
• RNA Biology

Background:

• The precise molecular targets of mycotoxins remain largely unknown.
• Long non-coding RNAs (lncRNAs) are increasingly recognized for their roles in cellular responses to environmental toxins.
• Existing studies suggest lncRNAs are involved in mycotoxin-induced apoptosis, cell death, and organ damage.

Purpose of the Study:

• To investigate the hypothesis that lncRNAs are potential molecular targets of mycotoxins.
• To explore the upstream and downstream regulatory roles of lncRNAs in mycotoxin toxicity.
• To elucidate the molecular mechanisms underlying mycotoxin-induced cellular damage.

Main Methods:

• Analysis of existing cell and animal experimental data on lncRNA expression and mycotoxin exposure.
• Review of literature on signaling pathways (e.g., mTOR/FoxO, NF-κB) involved in mycotoxin toxicity and lncRNA interactions.
• Hypothetical framework for future experimental investigation.

Main Results:

• Mycotoxins modulate lncRNA expression, influencing apoptosis, cell survival, and organ-specific damage (liver, chondrocytes).
• lncRNAs interact with key signaling pathways, including mTOR/FoxO and NF-κB, impacting cellular processes and immune evasion.
• lncRNAs act as potential upstream regulators of downstream events like oxidative stress and apoptosis.

Conclusions:

• lncRNAs are strongly implicated as key players in mycotoxin-induced toxicity.
• Targeting lncRNAs may offer a novel therapeutic strategy for mitigating mycotoxin effects.
• Further investigation into lncRNA-mycotoxin interactions is crucial for understanding toxicity mechanisms.
