Overexpression of polycomb protein contributes to epigenetic repression in oral squamous cell carcinoma (OSCC) ensuing in poor prognosis and aggressive phenotype. Several plant-based compounds could help prevent epigenome alteration and cancer progression, but their low bioavailability limits their therapeutic activity.

In this study, we have synthesized genistein nanoformulation (GLNPs) and evaluated its epigenetic regulation mechanism for selective apoptosis induction in OSCC.

Lactalbumin was used to prepare nanoformulation of Genistein. The mechanism of epigenetic regulation and selective apoptosis by Genistein loaded nanoparticles was studied in OSCC cell line JHU011 and fibroblast cell line L929 using immunofluorescence, Western blotting and ChIP-qPCR assay.

We have found that GLNPs treatment selectively induced apoptosis in OSCC compared to the normal fibroblast cells. This selective effect in OSCC is achieved through enhanced reactive oxygen species (ROS) generation followed by Bax mitochondriariptional repression and selectively induce apoptosis in human oral squamous cell carcinoma.
In our previous study, we demonstrated the hepatoprotective effect of Herpetospermum pedunculosum in cholestatic rats. A bioassay-guided study also led to the identification and isolation of a lignan, dihydrodiconiferyl alcohol (DA) from the seeds of H. pedunculosum.

To investigate whether DA could alleviate cholestasis and determine the mechanisms underlying such action.

Male Sprague-Dawley (SD) rats were administered with DA (10, 20 or 40mg/kg) intragastrically once daily for 7 days prior to treatment with α-naphthylisothiocyanate (ANIT) (60mg/kg). Selleckchem Benserazide We then evaluated the levels of a range of serum indicators, determined bile flow, and carried out histopathological analyses. Western blotting was then used to investigate the levels of inflammatory mediators and the Farnesoid X Receptor (FXR), proteins involved in the downstream biosynthesis of bile acids, and a range of transport proteins. Molecular docking was used to simulate the interaction between DA and FXR. Cell viability of human hepatocytes (L-02, and Na+/taurocholate Co-transporting Polypeptide, in both guggulsterone-inhibited and Si-FXR L-02 cells. Moreover, DA enhanced the mRNA and protein expression of FXR, and its downstream genes and proteins, in L-02 cells containing an FXR-overexpression plasmid.

DA may represent an effective agonist for FXR has significant therapeutic potential for the treatment of cholestatic liver injury.

Numerous observations of this has already been made for a range of viruses with each type of virus seemingly applying its own unique tactics to accomplish this unifying goal. In this light, metabolic reprogramming of the infected cell is largely beneficial to the virus and not to the host. On the other hand, virus-induced metabolic reprogramming represents a transformed self with distorted cellular and extracellular levels of distinct metabolites and metabolic by-products. This review briefly outlines current knowledge of virus-induced metabolic reprogramming, discusses how this could be sensed by the infected host to initiate anti-viral programs, and presents examples of innate anti-viral mechanisms of the host that target the availability of biomolecules to block viral replication.Metabolic reprogramming of macrophages during immune activation can generate diversified types of small molecule metabolites, which in turn induce post-translational modifications (PTMs) on proteins. Understanding the functional implications of these modifications requires precise identification of them from complex biological samples. We herein review recent progress in systematic discovery of immunometabolite PTMs by chemical proteomics.The rise of antibiotic-resistant bacteria has led to renewed interest in the use of their natural enemies, phages, for the prevention and treatment of infections. However, phage therapy requires detailed knowledge of the interactions between these entities. Bacteria defend themselves against phage predation with a large repertoire of defences. Among these, CRISPR-Cas systems stand out due to their adaptive character, mechanistic complexity and diversity, and present a significant hurdle for phage infection. Here, we provide an overview of how phages can circumvent CRISPR-Cas defence, ranging from target sequence mutations and DNA modifications to anti-CRISPR proteins and nucleus-like protective structures. An in-depth understanding of these phage evasion strategies is crucial for the successful development of phage therapy applications.Phages are versatile agents for delivering a variety of cargo, including nanomaterials, nucleic acids, and small molecules. A potentially important application is treatment of antibiotic-resistant infections. All of these applications require molecular engineering of the phages, including chemical modification and genetic engineering. Phages are remarkably amenable to such engineering. We review some examples, including for controlled phage therapy. We suggest that the ability of phages to support extensive engineering may have evolutionary origins in the billions-year-old 'arms race' between bacteria and phages, which selects for sequences and structures that are robust in the face of rapid evolutionary change. This leads to high tolerance of both naturally evolved mutations and synthetic molecular engineering.Recently, new developments of multiple-enzyme catalysis in enzyme scaffold designs have garnered much attention for their important applications. The reactions catalyzed by multiple protease which couldn't co-exist in solution would greatly facilitate the bottom up strategy for proteome analysis. In this study, a dual-enzyme microreactor with two proteases was successfully constructed for consecutive digestion under mild reaction conditions in aqueous solution based on hydrophilic ZIF-90 with size-selective sheltering, where chymotrypsin was encapsulated into the ZIF-90 framework through a biomimetic mineralization procedure and trypsin was then covalently adsorbed on the outer surface of ZIF-90. With extraordinarily uniform size and high protein loading capacity, the microreactor exhibited enhanced stability (including thermostability, pH stability and storage stability) and better digestion performance compared to in-solution digestion. Thus, the work presents a novel and general strategy for the design of high-performance biomimetic reactors for multienzymatic catalysis by altering the type of enzyme and further develops the great potential of biomacromolecules in catalysis application.
