“…Its capability to survive in such extreme conditions is reportedly due to the existence of broad and diverse group secondary metabolites [19]. Furthermore, Macroalgae are well reported to exhibit several UV-absorbing compounds [20], such as phlorotannins, a marine algal polyphenol which has demonstrated anti-UV activity [21]. Another common UV-absorbing compound found in marine macroalgae are the Microsporin-like Amino Acids (MAAs) [22].…”

Sunscreens today contain several synthetic UV (Ultraviolet) filter molecules to protect the skin epidermis from UV radiation damage. However, these molecules may create several negative effects on human skin. Due to this condition, there is an increase in the development of natural products to replace uses of these synthetic chemicals. Brown macroalgae Sargassum has been recently studied for its photoprotective activities. The purpose of this study is to investigate photoprotective activity of one of most abundant Sargassum species in Lombok coast; Sargassum cristaefolium. Spectrophotometry analysis with UV-VIS revealed the UV spectra absorbing capability of Sargassum cristaefolium (SC) in the UVA spectrum range (314–400 nm). Furthermore, spectrometry analyses with LC-MS revealed the existence of UV absorbing compound MAA-palythene. In correlation, SC ethanol extracts also demonstrate that it could protect DNA from UVA irradiation as analyzed in vitro in HeLa cell model. The effects of SC on UVA exposed-dorsal mice skin have also shown interesting results, as mice pretreated with SC before UVA exposure showed protective activity on the epidermal integrity similar as positive control. Whereas, UV exposed mice without SC or commercial products resulted in increased epidermal thickness, which is the common parameter of skin photoaging. In addition, pretreated mice with SC also show protective effects in the formation of collagen connective tissues. Overall, current results show promising photoprotective activity of SC against UV radiation. More advanced investigations of SC as a potential photoprotective agent would be reasonable for development of macroalgae-based natural skin protection products.

“…In algae, the production of polyphenols can be induced by UVR, which has confirmed its photoprotective function. There are other reports where it has been found that the availability of nitrates can affect the bio-generation of these compounds (Schmitz et al, 2018). This can be used as a tool when scaling production processes (Copia et al, 2012).…”

“…Extracts from the Phaeodactylum tricornutum microalgae can protect against the adverse effects of UVR, and in addition, it improves skin elasticity and firmness (Ariede et al, 2017). In the purification and elucidation of secondary metabolites responsible for the photo-protective activity, mycosporin-like amino acids, polyphenols and carotenoids have been widely reported (Schmitz et al, 2018).…”

“…Carotenoids are more representative of brown algae, they are found in some red algae and very low amounts in green algae (Łęska, Messyasz, Schroeder, 2018). The main carotenoids found in brown algae are fucoxanthin and β-carotene and in red algae lutein, zeaxanthin, and β-carotene (Bajpai, Prokop, Zappi, 2014;Łęska, Messyasz, Schroeder, 2018;Schmitz et al, 2018). Microalgae are considered the most important producers of carotenoids.…”

Skin is the largest and heaviest organ in the human body also one of the most important and act as a barrier that separates our organism from the environment. The nature of this cover is physical, chemical, and immunological. It controls the flow of substances between the environment and the body. Skin pH between 5-7 works as a chemical barrier that helps to maintain its integrity and natural microbiota (Dragicevic, Maibach, 2015).Langerhans cells, dermal dendritic cells and macrophages are specialized skin cells that make the skin an immunecompetent organ (Dragicevic, Maibach, 2015;Wiznia, Elbuluk, 2017). The skin carries out metabolic functions like vitamin D synthesis. Furthermore, thermo-regulation, excretion, endocrine and sensitivity are other functions performed by the skin. (Dragicevic, Maibach 2015) The histological structure of the skin consists of a complex architecture that has three fundamental layers: epidermis, dermis and hypodermis (Figure 1A). The epidermis is the outermost layer. (Wiznia, Elbuluk, 2017) The main constituent cells of this layer are keratinocytes corresponding to 95 %, the remaining 5 % of the cells are melanocytes, Langerhans cells and dermal dendritic cells (Dragicevic, Maibach, 2015;Wiznia, Elbuluk, 2017) Melanocytes fulfill the production of melanin, which is the main endogenous defense of the skin to protect us against UV-radiation (UVR) (Norman, Menendez, 2008). The dermis is the second layer of the skin and is thicker

“…In order to evaluate the response of 'Flester' cultivar regarding its reduced photosynthetic performance we also measured carotenoid and malondialdehyde (MDA) contents ( Figure S5). Carotenoids act as light harvesters, quenchers and scavengers of triplet state chlorophylls, and singlet oxygen species, dissipators of excess harmful energy during stress condition and membrane stabilizers [40]. MDA is produced from the lipid peroxidation of polyunsaturated fatty acid (PUFAs) in response to oxidative stress by ROS attack [41] but it has recently been suggested that MDA may act as a protection mechanism rather than being a damage indicator if the elimination of MDA and redox signaling regulation works correctly [41].…”

Cichorium endivia is a leafy crop closely related to Lactuca sativa that comprises two major botanical varieties characterized by a high degree of intraspecific morphological variation: var. latifolium with broad leaves (escarole) and var. crispum with narrow crisp curly leaves (endive). To investigate the relationship between leaf morphology and photosynthetic activity, escaroles and endives were used as a crop model due to the striking morphological diversity of their leaves. We constructed a leaf database for transcription factors (TFs) and photosynthesis-related genes from a refined C. endivia transcriptome and used RNA-seq transcriptomic data from leaves of four commercial endive and escarole cultivars to explore transcription factor regulatory networks. Cluster and gene co-expression network (GCN) analyses identified two main anticorrelated modules that control photosynthesis. Analysis of the GCN network topological properties identified known and novel hub genes controlling photosynthesis, and candidate developmental genes at the boundaries between shape and function. Differential expression analysis between broad and curly leaves suggested three novel TFs putatively involved in leaf shape diversity. Physiological analysis of the photosynthesis properties and gene expression studies on broad and curly leaves provided new insights into the relationship between leaf shape and function.
