While many research programs have focused on the challenge of developing small molecules that can inhibit protein-protein interactions, some researchers have taken the problem one step further by attempting to develop small molecules that mimic the essential features of an entire protein. An area of particular interest has been in the field of artificial transcription factors (ATFs), where the essential function of some transcription factors is to recruit and promote the assembly of a larger transcription complex, leading to the expression of a gene of interest. The goal of synthesizing small-molecule ATFs holds promise as a means to independently control the expression of genes such as those that are misregulated in cancer and disease.

Naringenin has the potential to regulate ferroptosis and mitigate renal damage in diabetic nephropathy (DN). However, it remains unclear whether the naringenin's effects in DN are linked to its ability to regulate ferroptosis. This study investigated the potential anti-ferroptosis properties of naringenin in high glucose (HG)-induced renal tubular epithelial cell models.

Abdominal aortic aneurysm (AAA) is a severe cardiovascular disease (CVD) that is partly attributable to endothelial dysfunction, inflammatory response, and angiogenesis. G protein-coupled receptor 4 (GPR4), a proton-sensitive G protein-coupled receptor that is abundantly expressed in vascular endothelial cells, has been associated with numerous physiological functions. Nevertheless, its potential involvement in the development of AAA remains unexplored.

Increasing evidence suggests that inhibition of receptor-interacting serine/threonine-protein kinase (RIPK) 1/RIPK3/mixed lineage kinase domain-like pseudokinase (MLKL) necrosome has protective effects in vivo models of painful conditions seen in humans associated with inflammation and demyelination in the central nervous system. However, the contribution of RIPK1-driven necroptosis to inflammatory pain remains unknown. Therefore, this study aims to determine the effect of necrostatin (Nec) -1s, a selective RIPK1 inhibitor, on lipopolysaccharide (LPS)-induced inflammatory pain and related underlying mechanisms.

Berberine (BBR), an isoquinoline alkaloid abundant in Coptis chinensis, exhibits anti-tumor and hypoglycemic properties. The regulation of tumor cell homeostasis and metabolism is greatly influenced by Hypoxia-inducible factor-1α (HIF-1α). This research aims to elucidate whether BBR inhibits the progression of hepatocellular carcinoma (HCC) by modulating HIF-1α expression.

Objective This study investigated the regulatory effect of high mobility group protein B1 (HMGB1) in the peripheral blood of patients with primary immune thrombocytopenia (ITP) on myeloid dendritic cells (mDC) and Th17/regulatory T cells (Treg) balance. Methods The study enrolled 30 newly diagnosed ITP patients and 30 healthy controls.Flow cytometry was used to measure the proportion of mDC, Th17, and Treg cells in the peripheral blood of ITP patients and healthy controls.
