Background: Despite the current therapeutic treatments including surgery, chemotherapy, radiotherapy and more recently immunotherapy, the mortality rate of lung cancer stays high. Regarding lung cancer, epigenetic modifications altering cell cycle, angiogenesis and programmed cancer cell death are therapeutic targets to combine with immunotherapy to improve treatment success. In a recent study, we uncovered that a molecule called QAPHA ((E)-3-(5-((2-cyanoquinolin-4-yl)(methyl)amino)-2-methoxyphenyl)-N-hydroxyacrylamide) has a dual function as both a tubulin polymerization and HDAC inhibitors.

However, understanding whether these alterations participate in RA development and can be considered putative therapeutic targets remains undetermined.In this study, we combined quantitative Trp metabolomics in the serum from patients with RA and corrective administration of a recombinant enzyme in experimental arthritis to address this question.

- The study investigates how chronic exposure to food-grade titanium dioxide (fg-TiO), a common food additive, affects the development of food allergies (FA) in young males through impacts on intestinal health and immune response.
- Researchers assessed the health and immune system of offspring whose mothers were fed diets either enriched with fg-TiO or control food from preconception to weaning, finding altered gut barrier and microbiota compositions.
- Findings indicate that perinatal exposure to fg-TiO may decrease the ability to develop oral tolerance to cow's milk proteins, showing a significant predisposition to food allergies, particularly in male subjects.
The food industry has always used many strains of microorganisms including fungi in their production processes. These strains have been widely characterized for their biotechnological value, but we still know very little about their interaction capacities with the host at a time when the intestinal microbiota is at the center of many pathologies. In this study, we characterized five yeast strains from food production which allowed us to identify two new strains with high probiotic potential and beneficial effects in a model of intestinal inflammation.

Here, we examined the effect of antibiotics (ATB) on the composition of bacterial and fungal microbiota and how the administration of CNCM I-745 influences both microbiota.
Methods: In order to get closer to the human microbiota, the mice used in this study were subjected to fecal microbiota transfer (FMT) using human feces and subsequently called human microbiotaassociated (HMA) mice.
