Researchers have mapped how the tick Haemaphysalis longicornis responds molecularly to cinnamaldehyde, a plant-derived compound being explored as a low-risk alternative to synthetic pesticides. Using an integrated multi-omics approach combining metabolomics, transcriptomics and proteomics, the team exposed ticks to sublethal and lethal concentrations of the compound and documented distinct metabolic, transcriptional and proteomic responses across the treatment groups.
Enrichment analysis of the resulting data pointed to biological processes and pathways tied to xenobiotic detoxification, binding activity, responses to harmful biological agents, longevity, membrane integrity and other defense-related physiological functions. The most striking finding emerged from the integrated analysis of all three omics layers: the mineral absorption pathway stood out as a significant pathway in the response to the LC50 concentration of cinnamaldehyde.
Within that pathway, the genes SGLT1 and HCP1 showed increased expression, while CTR1 and ATOX1 showed decreased expression. The authors validated these patterns by RT-qPCR, and the expression trends of all four genes were consistent with the multi-omics results, lending support to the pathway’s involvement in the tick’s physiological response.
The study, published as an open-access article in Parasites & Vectors, is presented as an accepted manuscript shared early for faster access, and its conclusions are framed accordingly. The authors state that the integrated analysis provides insights into the molecular response of H. longicornis to cinnamaldehyde and identifies mineral absorption as a candidate process associated with that response, offering a foundation for further exploration toward environmentally friendly tick management products. As the underlying mechanisms of phytochemicals remain not fully understood, the work addresses a stated gap while leaving efficacy and mechanism questions open for future study.
