Treatment of actinic keratosis through inhibition of cyclooxygenase-2: Potential mechanism of action of diclofenac sodium 3% in hyaluronic acid 2.5.

Dermatol Ther 2018 Dec 6:e12800. Epub 2018 Dec 6.

DISSAL Section of Dermatology, University of Genoa-IRCCS, AOU San Martino-IST, Genoa, Italy.

Cyclooxygenase-2 (COX-2) and its metabolic product prostaglandin E (PGE ) are induced in response to growth factors, inflammatory cytokines, tumour promoters, activated oncogenes and, in the skin, ultraviolet (UV) radiation. Accumulating evidence suggests a role for the COX-2/PGE pathway in tumourigenesis in various tissue types including cutaneous squamous cell carcinoma. There is also strong evidence for a role in the development of actinic keratoses (AKs) - common dysplastic lesions of the skin associated with UV radiation overexposure - considered as part of a continuum with skin cancer.

Brahma deficiency in keratinocytes promotes UV carcinogenesis by accelerating the escape from cell cycle arrest and the formation of DNA photolesions.

J Dermatol Sci 2018 Nov 22. Epub 2018 Nov 22.

Dermatology, Central Clinical School, and Bosch Institute, University of Sydney, Sydney, NSW, Australia; Centenary Institute, Cancer Services, Royal Prince Alfred Hospital, Dermatology, Bosch Institute, University of Sydney, Camperdown, NSW 2050, Australia. Electronic address:

Background: Ultraviolet radiation (UVR) is the principal cause of keratinocyte skin cancers. Previous work found that levels of the chromatin remodelling protein, Brahma (Brm), are diminished during the progression from actinic keratoses to cutaneous squamous cell carcinomas in humans, and its loss in UV-irradiated mouse skin causes epidermal hyperplasia and increased tumour incidence.

Methods: The skins of mice and mouse and human keratinocytes deficient in Brm were exposed to UVR and evaluated for cell cycle progression and DNA damage response. Read More

Influence of humidity and iron(iii) on photodegradation of atmospheric secondary organic aerosol particles.

Phys Chem Chem Phys 2018 Dec;20(47):30021-30031

Paul Scherrer Institute, Laboratory of Environmental Chemistry, 5232 Villigen PSI, Switzerland.

The absorption of solar actinic radiation by atmospheric secondary organic aerosol (SOA) particles drives condensed-phase photochemical processes, which lead to particle mass loss by the production of CO, CO2, hydrocarbons, and various oxygenated volatile organic compounds (OVOCs). We examined the influence of relative humidity (RH) and Fe(iii) content on the OVOC release and subsequent mass loss from secondary organic aerosol material (SOM) during UV irradiation. The samples were generated in a flow tube reactor from the oxidation of d-limonene by ozone. Read More

Androgen receptor functions as transcriptional repressor of cancer-associated fibroblast activation.

J Clin Invest 2018 Dec 5;128(12):5531-5548. Epub 2018 Nov 5.

Cutaneous Biology Research Center, Massachusetts General Hospital, Boston, Massachusetts, USA.

The aging-associated increase of cancer risk is linked with stromal fibroblast senescence and concomitant cancer-associated fibroblast (CAF) activation. Surprisingly little is known about the role of androgen receptor (AR) signaling in this context. We have found downmodulated AR expression in dermal fibroblasts underlying premalignant skin cancer lesions (actinic keratoses and dysplastic nevi) as well as in CAFs from the 3 major skin cancer types, squamous cell carcinomas (SCCs), basal cell carcinomas, and melanomas.

Genetic characterization of a flap1 null mutation in Arabidopsis npq4 and pgr5 plants suggests that the regulatory role of FLAP1 involves the control of proton homeostasis in chloroplasts.

Photosynth Res 2018 Nov 2. Epub 2018 Nov 2.

Center for Biological Resources & Informatics, Tokyo Institute of Technology, Yokohama, 226-8501, Japan.

Precise control of the proton concentration gradient across thylakoid membranes (ΔpH) is essential for photosynthesis and its regulation because the gradient contributes to the generation of the proton motive force used for ATP synthesis and also for the fast and reversible induction of non-photochemical quenching (NPQ) to avoid photoinhibition and photodamage. However, the regulatory mechanism(s) controlling ΔpH in response to fluctuating light has not been fully elucidated. We previously described a new NPQ-regulatory chloroplastic protein, Fluctuating-Light-Acclimation Protein1 (FLAP1), which is important for plant growth and modulation of ΔpH under fluctuating light conditions.

Dermatology Unit "Daniele Innocenzi", Department of Medical-Surgical Sciences and Bio-Technologies, Sapienza University of Rome, Fiorini Hospital, Polo Pontino, 04019 Terracina, Italy,

Actinic keratoses (AKs) are epidermal cutaneous neoplasia observed predominantly in middle-aged and older subjects with mainly photo type I and photo type II on sun-exposed surfaces as a result of DNA damage. AKs have historically been characterized as being "precancerous"; however, now it is considered by many authors a carcinoma in situ that can persist or progress to invasive squamous cell carcinoma (SCC) with metastatic potential. Despite the advances in the recognition of typical clinic, dermoscopic and histologic patterns, currently it is not yet possible to predict which AKs will progress to SCC. Read More
