Plant organelle C‐to‐U RNA editing factors can operate successfully in yeast (Saccharomyces cerevisiae) as an easily amenable eukaryotic system for their functional analysis

The FEBS Journal, EarlyView.
Plant‐type pentatricopeptide repeat proteins capable of C‐to‐U RNA editing perform faithfully when expressed in a new heterologous system, the yeast Saccharomyces cerevisiae. They were tested with constitutive and inducible expression and with a set of different solubility tags. PPR56, PPR65, and PPR78 from P.

A novel approach to target skin photodamage: Topical application of salt inducible kinase inhibitors

International Journal of Cosmetic Science, EarlyView.
UV‐induced photodamage leads to increased DNA damage and elevated MMP levels, which degrade collagen and contribute to wrinkle formation. SLT‐001 and SLT‐008, novel cosmetic ingredients that target salt‐inducible kinase, help reverse this effect by enhancing DNA repair, reducing MMP expression and decreasing erythema, thereby mitigating photodamage ...

New alternatives in photoprotection: Preparation and evaluation of lamellar silicate derivatives and their use as sunscreens

International Journal of Cosmetic Science, EarlyView.
The use of nanotechnology in sunscreens has increased, with various filters and organoclays tested for new intercalated formulations. As animal toxicity tests decrease, New Approach Methodologies are favoured. The S4 + OMC‐NC improved cell survival under SSL and showed antimutagenic properties, making it a promising candidate for safe photoprotection ...
