“…The proteomics platforms that have evolved over the past 20 years-gel, label, gel free/label free, targeted-are used to describe protein profiles, posttranslational changes, and interactions [45]. Isolation, separation, visualization, and precise protein identification are among the many aspects of any proteomic technique that ultimately determine its effectiveness [44]. Despite recent developments, more attention needs to be paid to protein extraction procedures, especially for proteins that are hydrophobic and large molecular mass proteins [39].…”

“…The suppression of genes for root development and pathogen response is a common consequence of abiotic stress [43]. There are reviews of further works that support these findings [44,45]. In a similar vein, additional research has shown that in Arabidopsis thaliana seedlings, gene expression for the peroxide-scavenging enzyme was influenced by CNTs [46].…”

In recent years, the relationship between plants and nanoparticles (NPs) has been the subject of extensive research interest. Hence, an ever-increasing number of perspectives connected with both the positive and adverse consequences of NPs application in plants are highlighted in this review. On the other hand, nanoparticles and their interactive effects on plants have raised concern regarding their harmful aspects. There are complex mechanisms evolved in plants for controlling the uptake, accumulation, and mobilization of nanoparticles that need to be discussed further, especially in the context of proteomics and genetic level. To fill this gap, there is a dire need for the integration and application of multiomics in plants to identify sensitive biomarkers responding to engineered NPs and to provide mechanistic insights in order to design safer and enhanced nano-enabled products for agriculture. For this purpose, transcriptomic technologies have essentially contributed to understanding of the molecular systems in plants against nanoparticle stress by laying out an association between gene expression and cell response. In light of this background, the current article attempts to summarize a variety of recent transcriptomic and proteomic contributions that have been made to establishing the genetic basis of nanoparticle uptake and the mechanism of stress response. The present article also looks at recent proteomic and transcriptomic studies to learn more about the intricate regulatory network that connects plant and nanoparticle stress responses.

“…16 The success of this partially protected method reduced, to some extent, the penetration of metabolic glycan probes into the cell membrane, and thus, a next generation of improved MCRs for high labeling of O -GlcNAc proteins is urgently needed. Meanwhile, our group also disclosed several probes for specific labeling of intracellular O -GlcNAcylated proteins without this leading to S -glyco modification, including Ac 3 6deoGlcNAz 17 and Ac 3 4FGlcNAz. 18 Our findings indicated that subtle modifications of the structure of GlcNAc will, surprisingly, avoid this S -linked side reaction.…”

O‐GlcNAcylation is a prevalent protein modification in eukaryotic cells and increasing evidences indicated that over‐expressed O‐GlcNAcylation are intimately linked to the development and prognosis of prostate cancer. Thus, exploring this modification in the context of prostate cancer is vital for understanding the underlying mechanisms and hopefully used for future targeted therapies. In this paper, we use our previously established metabolic probes to comprehensively compare the labeling efficiency of O‐GlcNAc modified proteins in PC3 cells. Our results demonstrated that all the tested probes were non‐toxic to PC3 cells and only Ac4GlcNAz, Ac4GalNAz and Ac34deoGlcNAz exhibited robust labeling signals amongst the probes. Further investigations by western blot and flow cytometry analysis revealed that Ac34deoGlcNAz was a specific and efficient probe for intracelluar protein labeling with negligible S‐glyco‐modification signal. In addition, proteomic analysis further confirmed that 94% of the proteins identified by Ac34deoGlcNAz were in the form of O‐linked GlcNAc, these enriched O‐GlcNAcylated proteins were mainly involved in the regulated processes of prostate cancer. Our results here together prove Ac34deoGlcNAz is a safe and reliable probe for metabolic labeling O‐GlcNAc modified proteins in prostate cancer, providing a mean to fully exploit the regulatory mechanism of O‐GlcNAcylation in the process of prostate cancer.
