Chromatin-mediated gene transcription or silencing is a dynamic process in which binding of various proteins or protein complexes can displace nucleosomal histones from DNA to relieve repression or drive the gene into a highly repressed, silent state. Covalent modifications to DNA and histones associated with chromatin structural change play a crucial role in transcriptional regulation, with particular modifications on certain residues associated with a specific transcriptional outcome. In recent years a number of structural domains have been identified within chromatin-associated proteins, including DNA or RNA binding domains, protein-protein interaction domains and domains that recognize specific covalent modifications to histone tails. In this review we discuss the structural features of these protein modules and the functional roles they play in chromatin biology.

Mechanical wounding triggers rapid transcriptional and hormonal reprogramming in plants, primarily driven by jasmonate (JA) signalling. While the role of JA, ethylene, and salicylic acid in wound responses is well characterised, the contribution of strigolactones (SLs) remains largely unexplored. Here, for the first time, it was shown that SLs modulate wound-induced transcriptional dynamics in Arabidopsis thaliana.

Sepsis often leads to unpredictable consequences. The prognosis of sepsis has not been largely improved. We tried to construct a prognostic gene model related to the 28-day mortality of sepsis to identify the risk of mortality and improve the outcome early.

Robinin (RB) is an accepted antioxidant herbal product with known cardio-protective activity. To explore the anti-oxidative potential of RB in treating myocardial ischemia or reperfusion (MI/RI) damage in rats after inducing hypercholesterolemia (HC). HC was induced by administering cholesterol (2%) to rats for eight weeks.

This paper presents the generation and evaluation of a novel potential drug delivery platform for biologics, based on recombinant spider silk. Targeting CD40 for activation of antigen presenting cells, in order to overcome tumor induced T cell tolerance, have shown promising results in cell and animal models. However, further trials have gained limited results due to severe side reactions.

Background: Heat illness is a dangerous condition marked by a widespread inflammatory response. Although Pogostemon cablin (Blanco) Benth and its derivatives are clinically used, their mechanisms remain unclear.
Methods: 11 heat illness patients and 14 healthy volunteers from Southwest Medical University Affiliated Hospital were enrolled.
