Increased Genetic Instability in Exfoliated Oral Cells in Patients With Epidermolysis Bullosa

Oral Diseases, EarlyView.
ABSTRACT Objective To analyze the nuclear abnormalities of cytotoxicity—karyorrhexis (KR), karyolysis (KL), and pyknosis (PN)—and genotoxicity—micronucleus (MN) in exfoliated cells from different sites of the oral mucosa in patients with Epidermolysis Bullosa (EB) and a control group.

Deciphering Cold Stress Resilience: Multiomics Insights in Contrasting Wheat Genotypes From the Western Himalayas

Plant Biotechnology Journal, EarlyView.
ABSTRACT Cold stress threatens wheat productivity, particularly in regions with extreme climatic conditions. To elucidate the molecular mechanisms underlying wheat's response to cold stress, we performed a multiomics analysis integrating lipidomics, transcriptomics, proteomics and metabolomics.

Long‐Term Salt Exposure Reprograms the Nicotiana tabacum BY‐2 Suspension Proteome and Metabolome Toward Stabilization of the Core Metabolic Pathways, Protein Turnover Machinery Modifications, and Protective Metabolome Adjustments

Plant, Cell &Environment, EarlyView.
ABSTRACT In this study, we analyzed a unique Nicotiana tabacum BY‐2 line that was gradually adapted to and subsequently maintained in 190 mM NaCl for over 15 years. Years of continuous high salinity shaped a stable “new homeostasis” in BY‐2 suspension cells. Salt‐adapted cells were smaller and formed tighter clusters. Metabolomics revealed constitutive

Therapeutic effect of NEO400, perillyl alcohol conjugated to linoleic acid, in a mouse model of UV‐induced skin damage

Photochemistry and Photobiology, Volume 101, Issue 2, Page 338-349, March/April 2025.
In the present work with mouse models, we demonstrate that a novel compound, NEO400, is able to profoundly protect skin against damage caused by UV radiation (UVR) when it is applied to skin post‐UVR exposure. In comparison, Aloe vera or linoleic acid are unable to achieve a similar level of protection.
