Our recent data demonstrate that the CSB protein, besides its role in DNA repair, functions also as a master switch factor that can selectively influence the transcription of specific sets of genes, after DNA damage or hypoxia, by influencing the biological functions of p53. It is likely that the CSB protein, by modulating p53 activity after different cellular stresses would re-equilibrate the physiological response towards cell proliferation and survival instead of cell cycle arrest and cell death. Some important implications of these findings are discussed here.

Pancreatic ductal adenocarcinoma (PDAC) is one of the worst solid malignancies in regard to outcomes and metabolic dysfunction leading to cachexia. It is alarming that PDAC incidence rates continue to increase and warrant the need for innovative approaches to combat this disease. Due to its relatively slow progression (10-20 years), prevention strategies represent an effective means to improve outcomes.

Ultraviolet B (UVB) radiation is a major contributor to skin photoaging. Although mainly absorbed by the epidermis, UVB photons managing to penetrate the upper dermis affect human dermal fibroblasts (HDFs), leading, among others, to the accumulation of senescent cells. In vitro studies have shown that repeated exposures to subcytotoxic UVB radiation doses provoke HDFs' premature senescence shortly after the end of the treatment period.

High energy diets are a risk factor for intestinal barrier damage. Butyrate, a major energy source for intestinal epithelial cells, has been shown to improve barrier dysfunction and modulate the gut microbiota. In this trial, we examined the preventative effect of coated sodium butyrate (CSB) on high-energy and low-protein (HELP)-induced intestinal barrier injury in laying hens, and also worked to determine the underlying mechanisms by an integrative analysis of gut microbiota and the metabolome.

Cockayne syndrome (CS) is a segmental progeroid syndrome characterized by defects in the DNA excision repair pathway, predisposing to neurodegenerative manifestations. It is a rare genetic disorder and an interesting model for studying premature aging. Oxidative stress and autophagy play an important role in the aging process.
