ABSTRACT
The Pro-inflammatory cytokine, Interleukin 17A (IL-17A) plays a vital role in the pathogenesis of inflammatory-induced acute lung injury (ALI). But, the mechanisms of this pro-inflammatory cytokine in response to activation after replication stress are not yet known. Control on DNA replication (DR) is vital for maintaining genome stability. Minichromosome maintenance (MCM) proteins play essential roles in various cancers, but their involvement during ALI is not yet been discussed. The present study was carried out to assess the participation of IL-17A during replication stress and to evaluate the contribution of curcumin on this. Mass spectrometry-based proteomic approach has been used on mice lung tissues treated with IL-17A, as a prime mediator to cause injury and curcumin a natural polyphenol as an intervention. Several trends were identified from the proteomic subset which revealed that IL-17A induces expressions of proteins like MCM2, MCM3, and MCM6 along with other proteins involved in DR. Interestingly, curcumin was found in suppressing the expression levels of these proteins. This was also confirmed via validating LC-MS/MS data using appropriate molecular techniques. Pathway and gene ontology analysis were performed with DAVID GO databases. Apart from this, the present study also reports the unique contribution of curcumin in suppressing the mRNA levels of other MCMs like MCM4, MCM5, and MCM7 as well as of ORC1 and ORC2. Hence, the present study revolves around linking the replication stress by pro-inflammatory effects, highlighting the implications for ALI and therapies. This study, therefore, enhances our capacity to therapeutically target DR-specific proteins.
