Functional comparison of phototropin from the liverworts Apopellia endiviifolia and Marchantia polymorpha
In this study, we functionally compared phot from two different liverworts species:Apopellia endiviifolia (Aephot) andMarchantia polymorpha (Mpphot). The BL-dependent photochemical activity of Aephot was similar to that of Mpphot, whereas the thermochemical activity of Aephot was lower than that of Mpphot. Therefore, the phot-mediated signaling pathways of the two plant species may differ more in response to temperature than to BL. Furthermore, we analyzed the functional compatibility of Aephot and Mpphot in chloroplast movements by transiently expressingAePHOT orMpPHOT. The transient expression ofAePHOT did not mediate ch...

Extracts of Trichocline sinuata (Asteraceae) as natural sensitizers in the photodynamic inactivation of Candida albicans
Flora in the east-central region of Argentina may offer a vast array of opportunities to isolate new photoactive molecules or plant extracts, with high potential for use in antimicrobial photodynamic therapy (aPDT) against yeast. For this purpose, the photofungicidal potential ofTricholine sinuata ( “contrayerba”) againstCandida Albicans was determined. The highest photoinactivation againstC. albicans was observed for dicholormethanic extracts (MFC = 62.5 μg/mL). Furthermore, we determine that photochemical mechanisms dependent on oxygen (type I and type II) and independent of oxygen (photoadduct formation) are...

A single photodynamic priming protocol augments delivery of ⍺‐PD‐L1 mAbs and induces immunogenic cell death in head and neck tumors
A single PDP protocol using Lipo-BPD induces immunogenic cell death by releasing damage-associated molecular patterns (DAMPs) and augments the delivery of ⍺-PD-L1 antibodies in head and neck tumors. Created using Biorender.com using an academic license. AbstractPhotodynamic priming (PDP) leverages the photobiological effects of subtherapeutic photodynamic therapy (PDT) regimens to modulate the tumor vasculature and stroma. PDP also sensitizes tumors to secondary therapies, such as immunotherapy by inducing a cascade of molecular events, including immunogenic cell death (ICD). We and others have shown that PDP improves th...

Photobiomodulation therapy enhances neural differentiation of dental pulp stem cells via ERK1/2 signaling pathway
This study demonstrated that photobiomodulation therapy (PBMT) could promote the neural differentiation of DPSCs, and the mechanism was related to the ERK1/2 signaling pathway. The results provided evidence that PBMT could assist in the transplantation of DPSCs in the treatment of nervous diseases. AbstractPhotobiomodulation therapy (PBMT) is the application of a low-level laser device to generate physiological changes and provide therapeutic effects. Till now, the effects of PBMT on the neural differentiation of mesenchymal stem cells have been rarely reported. Herein, the potential effect and mechanism of PBMT on the neu...

Lycium barbarum polysaccharide inhibits blue ‐light‐induced skin oxidative damage with the involvement of mitophagy
Lycium barbarum polysaccharide (LBP), the main active ingredient extracted from the traditional Chinese medicineLycium barbarum, can ameliorate blue-light-induced skin damage in vitro and in vivo, which is closely related to its antioxidant effect involving mechanism of mitophagy. AbstractAlthough blue light can damage the skin to a certain extent, the pathogenesis of its damage remains still unclear. The available evidence suggests that oxidative stress may be the main cause of its damage.Lycium barbarum polysaccharide (LBP) has antioxidative effects in a variety of cells. In this paper, we investigated the protective rol...

Can methylated purine bases act as photoionization hotspots?
The direct photoionization of canonical nucleobases under ultraviolet radiation is difficult due to their high ionization potentials (IPs). Interestingly, as an important epigenetic modification, nucleobase methylation has a greater impact on lowering the IP, rendering photoionization under lower-energy UV irradiation possible. Through capturing and characterizing hydrated electrons and concomitant methylated base radicals, we demonstrate methylated purine bases can undergo direct low-energy UV photoionization with non-negligible one-photon ionization yields ((1.4 –5.0) × 10−3). Since these reactive radicals can t...

Alleviation of ultraviolet ‐B radiation‐induced photoaging using Saussurea medusa Maxim polysaccharide
Ultraviolet B radiation from sunlight can lead to photoaging, thickening of the dermis, and deep wrinkles. It triggers the production of inflammatory factors like TNF-a and IL-1, which then activate EGFR receptors in cells. This, in turn, activates MEK1/2 and ERK1/2, eventually causing an increase in the production of MMPs. The increased MMPs then degrade collagen and other extracellular matrix components, leading to skin inflammation and damage. However, the polysaccharides present inSaussurea medusa maxim can mitigate skin damage by this pathway. AbstractSaussureamedusa polysaccharide, the polysaccharide extract ofSaussu...

Molecular evolution of Cypridina noctiluca secretory luciferase for production of spectrum ‐shifted luminescence‐emitting mutants and their application in nuclear receptor–reporter assays
In this study, we generated blue- and red-shifted ( −16 and 12 nm) luminescence-emittingCypridina secretory luciferase (CLuc) mutants using multiple cycles of random and site-directed mutagenesis. Even for red-shifted CLuc mutant, which exhibited relatively low activity and stability, its enzymatic activity was sufficiently high for a luciferase assay (3.26 × 106 relative light unit/s), light emission was sufficiently prolonged (half-life is 3 min), and stability at 37°C was high. We independently determined the luminescence of these CLuc mutants using a luminometer with an optical filter. Finally, we replace...
