Inflammation in diabetes complications: molecular mechanisms and therapeutic interventions.

At present, diabetes mellitus (DM) has been one of the most endangering healthy diseases. Current therapies contain controlling high blood sugar, reducing risk factors like obesity, hypertension, and so on; however, DM patients inevitably and eventually progress into different types of diabetes complications, resulting in poor quality of life. Unfortunately, the clear etiology and pathogenesis of diabetes complications have not been elucidated owing to intricate whole-body systems.

Bacteria-Elicited Specific Thrombosis Utilizing Acid-Induced Cytolysin A Expression to Enable Potent Tumor Therapy.

Given the special microenvironment of solid tumors, live microorganisms have emerged as drug delivery vehicles and therapeutic agents. Here, an acid-induced therapeutic platform is constructed using attenuated Escherichia coli to express the cytolysin A protein. The bacteria can target and colonize tumor tissues without causing notable host toxicity.

Histone structures: targets for modifications by molecular assemblies.

The core histone proteins contain modification sites that are key elements in the regulation of the cell cycle, DNA replication and repair with histone assembly, control of gene expression, and transcriptional elongation. Much work has been done on the various molecular assemblies that remodel nucleosomes, methylate, ubiquitinate, and cause ADP-ribosylation of histones, and acetylate and phosphorylate core histone tails. The core histones are the final targets of the enzymes in the molecular assemblies.
