B u çalışmanın amacı, arı zehiri bileşenleri olan Apamin, Melittin ve Fosfolipaz A2'nin insan keratinosit hücre hattındaki UV hasarına karşı koruyucu ve tedavi edici özelliklerini belirlemektir. Arı zehirinin kozmetik ve tedavi edici etkileri önceki çalışmalarda bildirilmiştir, ancak zehirin hangi bileşenlerinin en fazla etkiye sahip olduğu bilinmemektedir. Bu amaçla ilk olarak bir in vitro UV hasar modeli tasarlandı. Arı zehirinin bileşenleri farklı konsantrasyonlarda test edildi. Hücre canlılığı, sitotoksisite ve apoptotik süreçler tasarlanan model üzerinde analiz edildi. Sonuç olarak, Apamin'in tüm konsantrasyonlarda UV ile indüklenen hücre ölümüne karşı önemli bir koruyucu etki gösterdiği gözlendi. Melittin'in ışık koruyucu etkileri tüm konsantrasyon sürelerinde gözlendi ve yüksek konsantrasyonda ışık koruyucu etkilerinin arttığı tespit edildi. Sonuçlarımız, Fosfolipaz A2'nin bir fotokoruyucu ve fototerapi ajanı olarak kullanılabileceğini gösterdi. Bu çalışma, arı zehiri bileşenlerinin UV hasarına karşı koruyucu ve tedavi edici özelliklerini gösteren ilk çalışmadır. Sonuç olarak, bu bileşenlerin UV kaynaklı hasara karşı başarılı fotokoruyucu ve fototerapötik ajanlar olabileceği gösterilmiştir, ancak hücreler üzerindeki toksik etkilerini en aza indirmek için daha detaylı çalışmalar yapılmalıdır.
This study aimed to investigate the therapeutic and protective effects of piperine and its combination with curcumin on reactive primary astrocyte cells and whether the bioavailability of curcumin increases when piperine is used together with it (synergistic effect). Recently, studies with astrocyte cells have attracted attention to neurodegeneration pathologies caused by aluminum exposure. In particular, it has become common to study the potential of herbal therapeutic agents to inhibit the effect of aluminum. This study investigated whether piperine, curcumin, and the synergistic effect of these two components have therapeutic and protective effects against aluminum in primary isolated astrocyte cells. In order to examine the protective effect, compounds at specific concentrations were applied to the cells before the aluminum application, and for the therapeutic effect, the effectiveness of the compounds was examined after the aluminum application. The efficacy of therapeutic agents individually and synergistically on aluminum exposure was analyzed in terms of cell viability, apoptosis, necrosis, and cytokine release. As a result, the obtained data showed that the % cell viability of different concentrations of piperine, curcumin and combined use of them on aluminum-induced damage in astrocyte cells were significantly higher in both the protective and therapeutic effect groups compared to the negative control. At the same time, a decrease in the number of apoptotic and necrotic cells was observed as a result of both Acridine orange and propidium iodide and TUNEL staining. The results of IL-6 and TGF-ß cytokine analysis also showed a decrease, which showed the importance of the synergistic effect of these two compounds. Considering all these results, it is the first time in the literature that the bioavailability-enhancing feature of piperine on curcumin has been demonstrated in terms of aluminum damage in astrocyte cells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
