Background: Expression of KRT13, FAIM2 and CYP2W1 appears to be influenced by risk habits, thus exploring the associations of these genes in oral squamous cell cancer (OSCC) with risk habits, clinico-pathological parameters and patient survival may be beneficial in identifying relevant biomarkers with different oncogenic pathways. Materials and Methods: cDNAs from 41 OSCC samples with and without risk habits were included in this study. Quantitative real-time PCR was used to analyze KRT13, FAIM2 and CYP2W1 in OSCC. The housekeeping gene (GAPDH) was used as an endogenous control. Results: Of the 41 OSCC samples, KRT13 was down-regulated in 40 samples (97.6%), while FAIM2 and CYP2W1 were down-regulated in 61.0% and 48.8%, respectively. Overall, there were no associations between KRT13, FAIM2 and CYP2W1 expression with risk habits, selected socio-demographic and clinico-pathological parameters and patient survival. Conclusions: Although this study was unable to show significance, there were some tendencies in the associations of KRT13, FAIM2 and CYP2W1 expression in OSCC with selected clinic-pathological parameters and survival.

사이자이지움 클래비플로룸(Syzygium claviflorum (Roxb.) Wall. ex A.M. Cowan & Cowan, S. claviflorum)의 추출물 (잎, 줄기, 열매, 꽃)의 화장품 소재로써 활용되기 위한 생리활성 능력을 검증하였다. 첫번째로, S. claviflorum 추출물은 DPPH와 ABTS assay법을 이용한 항산화 실험에서 다양한 농도로 처리한 결과, 약 80% 이상의 자유 라디칼을 제거하였다. 사람 피부 표피 각질형성세포(human epidermal keratinocytes)를 이용한 세포독성 실험에서는 S. claviflorum 추출물은 낮은 세포독성을 보였다. 또한, S. claviflorum 추출물은 각질형성세포의 분화인자 (keratin (KRT)1, KRT2, KRT9, KRT10)와 피부장벽의 기능 유지에 중요한 involucrin (IVL), loricrin (LOR), filaggrin (FLG)과 claudin1 (CLDN1) 유전자의 발현을 현저히 증가시켰다. 특히, in vitro 아토피 피부염 실험에서 interleukin (IL)-4/IL-13에 의해 억제된 FLG 단백질 발현이 S. claviflorum 추출물에 의해 회복되었다. 따라서, 뛰어난 항산화 효능과 피부장벽 개선 기능을 보유한 S. claviflorum 추출물은 향후 아토피 피부염 치료제 및 화장품 개발에 유용한 소재가 될 것이다.

Skin is continuously exposed to a variety of environmental stresses, including ultraviolet (UV) radiation. UVB is an inherent component of sunlight that crosses the epidermis and reaches the upper dermis, leading to increased oxidative stress, activation of inflammatory response and accumulation of DNA damage among other effects. In the present study, the anti-wrinkle mechanism of Acorus gramineus callus culture supernatant (GB-AGS-PSC) was elucidated in UVB treated HaCaT keratinocytes. GB-AGS-PSC prevented the matrix metalloprotease 1 (MMP-1), elastin, and pro-collagen product and cytotoxicity and SOD inhibition. Quantitative polymerase chain reaction showed that GB-AGS-PSC-treated cells displayed dose-dependent increase in messenger RNA expression levels of Aquaporin 3 (AQP3), Keratin 1(KRT1), fillagrin, and hyaluronan synthase-2 (HAS 2) and decreased expression levels of matrix metalloproteinase-3, -9, and -13 in UVB treated HaCaT keratinocytes. Additionally, GB-AGS-PSC suppressed TNF-α, IL-1β, and IL-8 product for inflammatory responses in UVB treated HaCaT keratinocytes. Therefore, GB-AGS-PSC may be useful as an anti-photoaging resource for the skin.
