DDX28 Activators

The realm of DEAD-box helicases, including DDX28, plays a pivotal role in maintaining cellular machinery associated with ribosomal processes. Chemicals that target these processes weave a complex landscape of regulation for DDX28. Actinomycin D, through its ability to tether itself to DNA, interrupts RNA synthesis, thereby potentially leading to indirect modulation of DDX28 by hindering ribosomal RNA synthesis. In the same domain, 5-Fluorouracil, CX-5461, BMH-21, and Emetine emerge as potent influencers of rRNA processing, sketching out their indirect influence on DDX28.

Metabolic regulators like Rapamycin, which target mTOR-a key player in ribosome biogenesis-highlight another layer of control over DDX28. The intricate interplay between ribosomal proteins and DDX28 becomes more evident with Oxymatrine and Quercetin, both having ties to ribosomal protein modulation. The broader chromatin landscape and its influence on DDX28 cannot be sidestepped, as Garcinol, with its histone acetyltransferase inhibitory property, sheds light on how ribosomal DNA transcription might cascade down to DDX28 regulation. Pladienolide B and Epigallocatechin gallate, by influencing spliceosome function and ribonucleotide reductase respectively, broaden the spectrum of chemicals that have the potential to regulate the multifaceted functions of DDX28 in ribosome biogenesis.
